  • What is real? How do we know what is real?
    Okay, fair enough. I am not familiar with Lavoisier so that reference isn't informative to me. So you are saying that Lavoisier worked with precise instruments and Aristotle did not? That is the difference I see you pointing to.Leontiskos

    Aristotle worked with what he had -- but I'm not sure he had instruments at all, to be honest. His instrument was logic, description, empiricism, and interpretation of prior works on the subjects he was interested in.

    I'm saying Lavoisier's contribution to our intellectual heritage is scientific because he was building instruments to test theories and discover what the empirical formula for water was in a way that convinced the rest of the scientific community.

    Building instruments in accord with a theory does not look like philosophy, to me -- at all. So he serves as a contrast case to Aristotle who was a philosopher-scientist -- Aristotle is an empiricist, but he was born before a time when measurement was theorized at all. So it makes sense that he'd think there's a continuity between science and philosophy.
  • The Phenomenological Origins of Materialism
    I appreciate your thoughtful approach.

    I have some objections though.

    I think you've supported thesis 2 better than thesis 1.

    "Materialism", as I understand it, is not intuitive at all. I'm hesitant to guess anymore, but if I had to guess I'd say that "Dualism" is the "default" position of most people, if pressed; but mostly philosophy isn't interesting enough for people to define their categories that cleanly.

    The reason it is not intuitive is because of all the problems you listed with it. It needs to be defended in some sense.

    And I take umbrage with the notion of "default" in philosophy -- I think the default depends on one's environment they grew up in. So if you grew up in a spiritualist household then spirituality would be the "default", and so on for any other ontology.

    I. Indeed, the triumph of volanturist theories of liberty can be seen as stemming, at least in part, from the fact that the new conception of reason is incapable of ruling over a person because it is bereft of its own motivations (i.e., its desire for Goodness and Truth as such).

    II. One need only consider likely modern challenges to St. John of Damascus’s matter of fact claim that: “neither are all things unutterable nor all utterable; neither all unknowable nor all knowable. But the knowable belongs to one order, and the utterable to another; just as it is one thing to speak and another thing to know,” to see that labeling both modern and pre-modern views “correspondence theories” papers over a great deal of difference (St. John of Damascus. An Exact Exposition of the Orthodox Faith. Book I, Ch. II)

    III.
    Then, as the tower-clock calls us to come
    at the hour when God's Bride is roused from bed
    to woo with matin song her Bridegroom's love,

    with one part pulling thrusting in the other,
    chiming, ting-ting, music so sweet the soul,
    ready for love, swells with anticipation

    Paradiso, Canto X, lines 139-142 (Musa translation)

    IV. Much more could be said about how Han’s recent influential critique in The Agony of Eros relates to Dante’s conception of love and knowing. It’s worth noting that Han covers ground that is very similar to Pope John Paul II’s Theology of the Body in Simple Language, with the latter drawing heavily from the tradition Dante represents.

    Han quotes Emmanuel Levinas’s Time and the Other (pg. 11-12) approvingly, questioning if the erotic love must always be a “failure” if it is defined in terms of “grasping,” “possessing,” or “knowing,” since these presuppose the conquest (and so elimination) of the other, and are “synonyms of power.”
    However, Levinas’s inclusion of “knowing” in the paradigm of power presupposes the modern notion of knowledge. This is not the knowing of ecstasis one finds in Plato and much of the pre-modern tradition, nor is it the "knowing by becoming" of the Neoplatonic ascent. Rather it is a knowing where a static self lays hold of the other and makes it a part of itself, consuming it. There is no "going out" or "being penetrated" in such a view, but merely "acquisition."

    This shift in “knowing” makes certain a sort of sense when one considers the modern reduction of man's rationality to discursive ratio alone. Aquinas himself says that ratio is to acquisition (and movement) as intellectus is to possession (and rest). The latter is, of course, likened to "possession," but this is not Levinas’s “possession as power.” It is possession as respects rest in a goal, a rest in the other as an end, rather than a frenetic, never-ending movement, a need to extract from the other as means for the gratification of the self.

    V. Such a view of knowing also goes along with Ferdinand Ulrich’s conception of “being as gift,” which is heavily influenced by Aquinas and the medieval tradition.

    VI. Christian Moevs’s excellent work The Metaphysics of Dante’s Comedy explores these notions of “knowing by becoming,” and “knowing as self-knowledge” in depth.

    VII. Understanding the role of love vis-à-vis reason is complicated by the fact that “love” has itself been subject to a sort of deflation. We can see this in the collapse of several unique concepts (i.e., philia, agape, pragma, stroge, eros, and ludus) into a single English word: “love.” Today, one finds the language of the buffered, atomized, discursively rational economic actor (the goal-driven consumer) even in the language of romantic relationships. Be it in guides on attracting "high value males," and not being a "pick-me," aimed women, or the "attraction through competition," and "peacocking" schemes of male-oriented advice writers (the self-described “pick-up artists” of the online “Manosphere”), Homo oeconomicus appears to have replaced Homo sapiens.

    VIII. Another of Dante’s sources, Dionysius the Areopagite uses similar circle imagery in De Divinis Nominibus (Book IV, Chapter IX):

    Further, there is a movement of soul, circular indeed,----the entrance into itself from things without, and the unified convolution of its intellectual powers, bequeathing to it inerrancy, as it were, in a sort of circle, and turning and collecting itself, from the many things without, first to itself, then, as having become single, uniting with the uniquely unified powers, and thus conducting to the Beautiful and Good.

    IX. For instance, in the Prolegomena to Any Future Metaphysics, Kant stakes our ability to distinguish dreams from reality on “connection according to [discursive] rules that determine the combination of representations” in experience, rather than on any definite relation between the actuality of things and their appearances (4.290).

    X. For instance, Wittgenstein’s influential On Certainty takes up many of the same questions about justification and knowledge addressed by Aristotle’s Posterior Analytics. Yet the two thinkers come to radically different conclusions on the nature of knowledge, in large part because intellectus is not considered as an option in the later work.

    XI. In Christian terminology, this would be the rule of the “Flesh.” Yet it is important to note that the “Flesh” is not simply the body, nor is it the sensuous appetites or passions. These are to be purified and redirected towards what is truly good, not uprooted. The appetites and emotions are an important part of the person, and the human being’s perfection in “the age to come” involves the restoration of their body. Rather the “Flesh” represents an orientation towards finite goods and away from God, the ultimate end of human existence. Because it is the intellect that knows the good as good, it is only when the intellect rules that man can be directed towards goodness itself, and so escape the allures of the “World” and “Flesh.”

    XII. It is instructive that Virgil makes this pronouncement before Dante is led to Limbo, with its bucolic scenery and its brightly glowing seven walled castle (likely symbolizing the seven “liberal arts” by which men are made free and the “light of intellect,” as suggested by Musa pg.103). The imagery here recalls the Earthly Paradise atop Mount Purgatory, a “heaven on Earth,” that Virgil, human reason, was ultimately capable of directing the Pilgrim to. Indeed, as Gerald Walsh suggests, had Dante wished to write a Human Comedy, an ode to humanism, the story might have ended with Virgil bringing Dante to that summit, to a Limbo-like Heaven atop Mount Purgatory. In so doing, Walsh claims Dante would have advanced a view of man’s telos in line with Condorcet, Kant, and Hegel (Gerald Groveland Walsh. Dante’s Philosophy of History. The Catholic Historical Review, Vol. 20, No. 2 (Jul., 1934), pp. 117-134).
    Yet Canto IV begins with Virgil telling the Pilgrim that he is now descending “into the sightless world” (Canto IV line 13), and the air of Limbo is filled “the sounds of sighs of untormented grief” (line 28). Hence, we must not forget that for Dante, those in Limbo are still “damned.” These souls have “lost the good of intellect” in that intellect can no longer bring them to man’s natural end. They are consigned to endless motion, never reaching satisfaction. They have seen the Beloved, but cannot reach Him.
    Dante’s narrative here, far from showcasing a “secular semi-heaven,” should rather be taken as a potent critique of ethical systems that take the Good to be the proper target of rational thought and will, but in the end merely an “intentional object” (ens rationis but not ens reale). Such a system supposes that, though we might become true self-movers, exercising a rational freedom, our movement is ultimately every bit as vain as Satan’s fruitless kicking (and so in some sense still irrational).

    XIII. Such an association of multiplicity with sin is a foundational part of the Christian tradition. For instance, Origen of Alexandria, often regarded as the first systemic Christian theologian, writes in his On Prayer (Chapter XII. The Lord’s Prayer:: The Preface in Matthew):

    There is no unity in matter and in bodily substances, but every such supposed unity is split up and divided and disintegrated into many units to the loss of its union. Good is one; many are the base. Truth is one; many are the false. True righteousness is one; many are the states that act it as a part. God’s wisdom is one; many are the wisdoms of this age and of the rulers of this age which come to nought. The word of God is one, but many are the words alien to God.

    XIV. A look at how St. Thomas defines “spirit,” in contrast to “soul” might be helpful here. The spirit is the soul vis-a-vis its transcendence of the body (e.g. ST 1.97.3). When we consider the “spirit,” the agent of the operations of intellect and will is the soul considered in its distinction from the body (as opposed to its unity with the body). The sensible appetites, which attract us to finite goods that cannot be freely shared, are excluded from spiritual activities (ST 1.75.2).

    Hence, we could think of envy, and all of our competition for status, wealth, etc., as in some sense a misordering, since it involves the lower part of the soul (i.e. sensible) ruling over the higher part (i.e. the rational). It is also a misuse of our body, if we consider the body to be primarily a vehicle for the spiritual life, that is, a conception of the body as sacramental (e.g. in Pope John Paul II’s Theology of the Body in Simple Language).

    XV. St. Bonaventure, one of Dante’s many sources (and a soul he encounters in the Heaven of the Sun), is instructive here:

    The creatures of this sensible world signify the invisible things of God [Rom. 1:20], partly because God is of all creation the origin, exemplar, and end, and because every effect is the sign of its cause, the exemplification of the exemplar, and the way to the end to which it leads; partly from its proper representation; partly from prophetic prefiguration; partly from angelic operation; partly from further ordination. For every creature is by nature a sort of picture and likeness of that eternal wisdom… (Itinerarium Mentis in Deum. Chapter 2.12)

    XVI. Dante’s conception here is in line with the classical Christian tradition. For example, we could consider the famous adage from St. Maximos the Confessor that:
    Nothing created by God is evil. It is not food that is evil but gluttony, not the begetting of children but unchastity, not material things but avarice, not esteem but self-esteem. It is only the misuse of things that is evil, not the things themselves.
  • The Phenomenological Origins of Materialism
    This is very much in line with how I see science.
  • What is real? How do we know what is real?
    Well, it's not that a number holds for the iterative set, but rather that a relation holds for the iterative set. But yeah, that's close.Leontiskos

    Fair.

    Right, though a species is not a set if we wish to speak more carefully.Leontiskos

    How would we differentiate it? It looks a lot like set theory to me.

    Why do you see what you describe of Aristotle's method as "mathematical induction"?Leontiskos

    Because, for him, the genera are real. When he moves up the chain there's no such thing as a black swan, for instance. It's different from mathematical induction in that it's about concretes, but it's like mathematical induction because the sets are real and the induction is thought to apply to all cases, which is what secures the claim to validity. Also, since I'm thinking about these as sets, where a genera is only a more general set than some given species, so I think he quite literally thinks the world is structured like his categories. There's still a basic material, but it requires some form -- like a cause -- in order for something to be real. This makes sense for him because ultimately where we end up is in a finite universe which is produced by the mind of God thinking himself into being. So the categories are a part of our world, and not just our experience, and certainly not just a way of ordering our thoughts. That's why there wouldn't be any invalidity in moving up, inductively -- the categories have an essence which makes it to where there's no problem making an inference from the particular to the general.


    For myself I think of these as ways of ordering our thinking rather than as an ontology. The world isn't constrained by our logic, and frequently demonstrates this. But it's easier to see that when we have so much knowledge that no one person will ever be able to dwell on it. In Aristotle's day it makes sense to continue the research programme he set up in the manner that he did.

    Basically because we can always be wrong when we follow a procedure of induction it's never valid -- there is at least one case where the inference could be false, where we are mistaken about the object we are talking about, so it fails to the basic definition of validity. But since it doesn't structure reality itself that's not as big of a deal for me.
  • What is real? How do we know what is real?
    In math we can form an induction which is valid by starting with a particular case and then proving that it holds for all cases so that the individual number, say n=0, holds for all n +1, and so on.

    But with Aristotle I think of his categories more like trees in set theory where the trees are increasingly wider sets that encompass the lower sets as their species -- so there are individuals, but then sets become individuals, and we can make inferences about the world because these sets aren't just a means for us to organize our thoughts, but rather are depictions of the world as it is -- so that the induction which takes place from an individual, like a human, can hold for the more general category when we utilize that individuals essence that fits within a wider category.

    Does this make any sense at all?

    EDIT: Though if we were to build a tree of Aristotle's concepts it would look "inverse" because there'd be one node at the top -- being -- under which all the other genera are species, and at the bottom you'd have all the individuals which the sets "contain"

    The hylomorphism that he espouses makes sense of why one could do this with respect to reality.
  • What is real? How do we know what is real?
    Eh, well how do we view induction about math? When you say that I think of inductive mathematical proofs, which do not remind me of anything in Aristotle. So I'm at a loss again.Leontiskos

    Good point. I think Aristotle sees his categories as mathematical inductions because he empirically witnessed them.

    I see them as mathematical inductions because I read Aristotle as feeling justified in writing his metaphysics because he had covered all the theories prior, showed their weaknesses and strengths, and expressed the truth given their inputs -- in light of his prior analytics I think he thought it possible to find true categories, such as the four causes, which would resemble the necessary conclusions of his prior analytics.

    The categories looked real, as they do today -- but he decided, in good taste, to philosophize them. (or write down his notes so he could teach tomorrow, flip a coin)
  • What is real? How do we know what is real?
    I mean, that's impressive if you've read all of that. I sure haven't.Leontiskos

    Only in english, and years ago. Something like 15 years. I don't doubt that my reading is rusty.

    But, yes. I wouldn't bother to say something here unless I had at least some reading, experience, or knowledge that relates.

    Different in what ways? And what is his method? I asked for your source for your ideas about "Aristotle's view of induction," and you literally pointed to seven different works without giving any specific references. That doesn't help me understand where your ideas about "induction" are coming from.Leontiskos

    Fair questions.

    The posterior analytics deals with induction, by my memory. And I want to add that I think Aristotle's notion of induction is not the same as induction today. But I grant you that I didn't give the specificity you asked for: My reading is certainly rusty.

    I feel we're getting closer here now, though, in terms of not talking past one another.

    The ways that Lavoisier and Aristotle are different, by my head-cannon at least, is that Lavoisier didn't question the enlightenment premises as much as pursued them and did them well.

    ***

    I think Aristotle's method -- Lavoisier I think didn't invent a method as much as adopted one -- is to review what has been said, demonstrate its strengths and weaknesses, then show his conclusion.

    And, on top of that, Aristotle had empirical verification for his conclusions.

    For his "view of induction" -- I listed the sources I did because I thought thems would explain it... but maybe not. I can tell you in my own words, though, since that's more relevant to our conversation: Aristotle views induction about objects in the same way we view induction about math. Since there are no other categories he is able to say "this is what that thing is. this is its being" -- but over time we've found that his methods are, while a good guess, not quite right either.

    He thinks that the world is harmonious. As I read the metaphysics, at least, all of being is within the mind of God thinking himself. Being is God thinking himself into being by thinking, and the categories apply because we can, through empirical research that climbs up, discover the essence of things.



    Now, I could be very wrong in my interpretation, but since you asked for how I understand Aristotle's notion of induction I'm giving an attempt at answering that more clearly.

    Science does, indeed, rock.

  • Differences/similarities between marxism and anarchism?
    Useful if starting a commune, which I may want to do.unimportant

    Now that you mention it -- one of the most practical ways of practicing anarchy in our world today is through the housing collective. Finding one and joining would be a way to learn from people actually doing the practice rather than reading a lot of long books, and you said you were interested in meeting up with people so that would be a good route.

    For an organization that's alive today which will put you in contact with anarchists I'd suggest Food not Bombs -- it has a diverse group of people and it's activist work so it's quite literally putting the ideas into practice. I know lots of anarchists tend to frequent that organization because of how it's run, and they'd know what possible institutional resources -- such as a housing collective -- might be in your area.

    BUT

    I can understand that the fruit might just look too juicy to be true, and dreaming big dreams can bring one down. I'd only do it if you enjoy it rather than out of a sense that one must accomplish the mission.
  • Differences/similarities between marxism and anarchism?
    Heh, fair enough. No worries.

    For myself the end-goal isn't as important to be achieved -- organizing with likeminded people was enough for me to want to know how it works. But it's not like you're going to earn a living or achieve anything immediately practical by studying it -- you'll improve your mind, which is good, but in terms of whether you ought study other things or not I can understand saying "OK, sounds interesting, but I'd rather deal with something more realistic"
  • What is real? How do we know what is real?
    No, you're not being clear, you're being intellectually dishonest - admitting Descartes was self censoring, but refusing to draw the conclusion that he wrote Meditations; a subjectivist epistemology in diametric opposition to Galileo's objectivist epistemology, as a defence against potential accusations of heresy.karl stone

    Couldn't it be the case that Descartes both censored himself and expressed himself? Or must we say, because he censored himself once all of what he did in his life is an act of self-censorship, including what he said?
  • What is real? How do we know what is real?
    Heh, I've once again not been clear.

    I agree Descartes was self-censoring. However, I don't think he was doing so in his philosophy, while he was doing so in his science.

    With respect to his science he was self-censoring, but I don't believe he was in his philosophy.

    And I'd hesitate to call Descartes' philosophy subjectivist, at least. Seems wrong to me given he wanted certain foundations for scientific knowledge in his philosophy.
  • What is real? How do we know what is real?
    I agree he was self censoring.

    I'm not sure I agree he wrote the Meditations to stop the inquisition, though. I think he liked both science and philosophy, and that his published philosophy could be read as his response to his circumstances -- I can't work scientifically because of these ideas in place, and so I'll set about doing the philosophical work that needs to be done in order that science might flourish.
  • What is real? How do we know what is real?
    Cool, I don't have that deep a knowledge of the sequence of events in his life so I'll go with it.

    But I know Descartes was not scared of doing science; covering himself from the ignorant, sure. And I agree he didn't think "subjectivism" is a valid epistemology -- that's not his thing. It's methodical, and not metaphysical, doubt.

    He wrote the meditations afterwards -- but it's still a methodical doubt, but like you noted: People often like the question but reject the answer.
  • What is real? How do we know what is real?
    I'm pleased to see so much analytic work going on. Working through the issues is the only way to work out how to fit all these pieces together - if that is possible.

    This is core analytic philosophy - looking closely at how the terms involved are being used, comparing them with formal systems we know are consistent, seeing what works and what does not. Bread and butter stuff. It's hard conceptual work.
    Banno

    Same.

    wasn't Descartes purpose to establish certainty, to avoid assumptions? I don't think he was particularly successful. Indeed, I don't believe he believed what he claimed to believe. I think he saw what happened to Galileo, and wrote an alternate epistemology more consistent with doctrine.karl stone

    He didn't establish certainty to avoid assumptions. He did not believe what he claimed to believe with respect to radical skepticism -- he explicitly says it's a methodical doubt rather than a doubt about the world.

    I think he withheld his publication of The World after seeing how Galileo was treated, but his philosophy differs from that.

  • Reading group: Negative Dialectics by Theodor Adorno
    Moliere I think this is what you were asking about here:Jamal

    Yes.

    Trying again with some rest and your rendition --

    "The meanwhile completely mismatched relationship (since degraded to a mere topos) between each Spirit and power, strikes the attempt to comprehend this hegemony by those inspired with their own concept of the Spirit with futility. The very will to do so betokens a power-claim which countermands what is to be understood."

    "meanwhile" contrasts the way the technician and the philosopher operates in a world which glorifies the technician. So the philosopher has turned away from positive cognitions and instead critiques itself while the technicians demonstrate their worth through power -- the mismatch then is between Spirit and Power.

    To add a punctuation mark to note how I'm reading this now...

    "The meanwhile completely mismatched relationship (since degraded to a mere topos) between each,Spirit and Power, strikes the attempt...."


    So the philosophers -- the introverted thought-architects who have a sense of Spirit, are struck with futility at even being able to comprehend the hegemony if the technician.

    The desire to comprehend this hegemony indicates a technician's knowledge, which in turn turns one away from Spirit.

    How's that sound to you?
  • What is real? How do we know what is real?
    When you talk about "Aristotle's view of induction," what texts are you referring to?Leontiskos

    I'm thinking about the physics, the metaphysics, on the weather, the prior analytics, the posterior analytics, parts of animals, and de anima.

    The prior and post analytics serve as his epistemology -- how he goes about making inferences. One by deduction and the other by induction. His treatises on weather, the soul, and the parts of animals too serve as examples of Aristotle applying his epistemology to the world at hand. The physics serves as a precursor to the metaphysics in that it is both a particular and general science since it deals with the topic of change, itself an entry into the study of the most general categories.

    I know you've read him and know him -- that's why I thought him a good example for us, and didn't think there'd be anything controversial in comparing his method to modern scientific methods and noting that they are different in what they are doing and arguing.

    How many pages have you read of any of them? If they are to serve as exemplars of the putative categories you attach to them, then apparently both of us must have strong exposure to all three. That seems doubtful. I have read lots of Aristotle, a small bit of Kripke (less than 70 pages), and nothing from Lavoisier. Have you read enough of each to take them as exemplars of categories such as "philosopher-scientist"? If not, they are not going to function as exemplars of anything substantial.Leontiskos

    Yes. Aristotle I'd say I'm most familiar with, and the bit of Kripke we've been referencing in this conversation is something I've read here on the forums. Lavoisier's contribution to science is his meticulous work on making precise instrumentation, which I gather is a clear difference between what both Aristotle and Kripke are doing.

    Now, readings get rusty and I make mistakes. But I'm not just using these just because -- Kripke got added to the mix, but Aristotle/Lavoisier is one I've just often thought through as a good comparison for finding a difference.

    Also, what I've noticed is that between us is they are not good examples because it's only leading to accusations of ignorance and showmanship.

    This is why learning to make real arguments is important.Leontiskos

    When you say this it seems like I must not know how to make a real argument, to your mind.

    I'd rather say that arguments don't reveal truth as much as serve as a check to ourselves -- ah, yes, there I messed up, that inference can't be quite right.
  • What is real? How do we know what is real?
    Okay, but do you have an argument for your conclusion? Are we no longer capable of induction in the 21st century? Was Aristotle wrong that we should have wide experience before drawing conclusions?Leontiskos

    Aristotle was not wrong in his time.

    But neither he nor we can make induction a valid move that secures knowledge.

    I say he wasn't wrong because I can see how his inferences are good given his circumstances, influences, and concerns not just from the rest of his writing but also from others' writings at the time, as well as writings about those writings.

    But I don't think we can travel by induction up to knowledge of God, for instance. I'd say there is a limit of some kind on our ability to judge on some questions we might want to answer or try to answer, but don't seem like we can reliably answer.

    Because the idea that such a process is defeated if we do not consider every single scientific claim that exists or is available in our linguistic context looks like a strawman. Even if we don't look at every single scientific claim, the process is still perfectly sound. And the person who looks at more evidence will be more suited to draw conclusions.Leontiskos

    I'm not sure that the process is sound. If we don't check every member of a set it's always possible to find a black swan. If it's always possible to find a black swan then we can't make the inference to climb our tower upwards towards being and the mind of God -- and ultimately reality, all as a unity.

    But if someone had something in mind other than Aristotle -- some modification which dealt with the notion that a single mind dealing with eternal categories does not bring one closer to being, but rather collective effort and distributing tasks and building trust such that we can work together, which tends to function better in an atmosphere where doubt is encouraged does.

    Also, the reason I like using historical examples is because it's meant to get around the notion that stipulation of a difference between philosophy and science is uninteresting -- we can say it and put up our terms and use the terms thereon in that way, but that misses the point.

    The historical examples provide a wider context other than standalone crisp definitions with syllogisms (though there's a time and place for that, too, I'm just explaining my method)
     
    Are you able to say what each is?Leontiskos

    Not exactly, but by way of example I've hoped to show a difference -- Aristotle is the philosopher-scientist, Lavoisier is the scientist, and Kripke is the philosopher.

    Not that I've been explicit or clear on this, really, but this is what the examples are meant to furnish -- as good examples of how to use the terms differently. The interpretation of each I'm meaning to use as why I might want to distinguish between the terms: look at what they mean and how they make inferences in these details and you'll hopefully catch onto the difference.

    There won't be necessary and sufficient conditions -- I don't think we can solve the problem of the criterion, though I think falsification is still an important subject unto itself -- but there will be stark differences between two family resemblances when we compare them.
  • What is real? How do we know what is real?
    But that is relevant to the OP -- if Aristotle secures knowledge of the real through a thorough review of all of what's known and induction towards being, such that he could be in a position to say the what-it-is-ness of a thing is, its real definition stating its essence, and this is the way by which we are saying there is no separation between science and philosophy, it seems that we'd need another way to coherently weave science and philosophy into the same practice in order to rely upon the science to claim it's relevant to the question "What is real?" -- which is largely where I'm contending against not science's relevance, but an over-reliance upon science in asking that question of reality.

    Basically I think philosophy and science are separate activities. That's the claim at stake from when I originally jumped with in this particular interlude.
  • What is real? How do we know what is real?
    So, for instance, I wouldn't say induction requires, but I'd say that the manner in which Aristotle's induction does. The way I see him move is securing his claim by an exhaustive survey of the extent arguments, a review of their merits and demerits followed by the conclusion of Aristotle's.

    So, yeah, you'd have to figure out some other way to be an Aristotelian, at least, if you wanted to progress to metaphysical truth in the manner of induction as Aristotle practiced it.
  • What is real? How do we know what is real?
    So your argument is that <Induction requires exhaustive knowledge; in order to have exhaustive knowledge we would have to survey every scientific claim; therefore induction is no longer possible in an age with a multitude of scientific claims>?Leontiskos

    Aristotle's use of induction to reach metaphysical truths would require him to survey the prior categories before he could move upwards towards being, as I understand it. That's why he does that prior to the metaphysics, at least as I read it -- I know it could just be a nomenclature thing and not something separate from physics. It definitely fits with his general process for generating knowledge -- start with the senses and move by induction through the categories, and he usually only moves after he thinks he's considered all the options.

    Not that the future couldn't be different, but now there are just that many options that this method is not feasible to do metaphysics with.
  • What is real? How do we know what is real?
    Your article says nothing at all about modus ponens, and so fails to answer my question.Leontiskos

    Blah, that's cuz I said it wrong. Modus Tollens.
  • What is real? How do we know what is real?
    Where does Aristotle say that one needs to consider every scientific claim?

    Do you have an argument that connects your premise to your conclusion, or am I right that your inference was invalid?
    Leontiskos

    I infer that because of his method of induction -- in order for him to be able to consider being, as such, he would have to start with the lower categories and move his way up. As I read the move from the physics to the metaphysics that's pretty much how we gets to his claims to have philosophical, metaphysical knowledge.
  • What is real? How do we know what is real?
    But how is a seed not a solid foundation? That seems to be precisely what a seed is. From an edit:Leontiskos

    Because it's small and could die and remains uncertain from its inception. It only grows in certitude with growth, or gets thrown out -- but its beginning is not its end, unlike a building -- an architectonic -- which builds from a solid beginning.

    Why must a metaphysical realist read and review every scientific claim?Leontiskos

    They don't have to unless they're following in the footsteps of Aristotle.

    Also, a note -- realism isn't the thing I contest. I think we decide how things are real, but most of the time we believe false things -- hence, skepticism.

    So X can falsify Y even when X is not true?Leontiskos

    Possibly, though there's a difference in kind here where "X" is some measurement and "Y" is some theory.

    So the theory that follows is just another guess that sounds good, but doesn't have any observable measurements which falsify it.

    I'm not sure what it means to say that falsification follows the form of a modus ponens. Does Popper say this somewhere?Leontiskos

    https://en.wikipedia.org/wiki/The_Logic_of_Scientific_Discovery

    I would say that there is truth and falsity, and then there are also beliefs about propositions, namely that they are true or false. Falsification can be viewed from either angle, but both are interconnected.

    I think TPF probably needs a thread addressing the deep problems with an intersubjective approach to truth, given how many people here are captive to it. We can falsify an individual's belief, but only if the content of that belief itself has a truth value (apart from any particular individual).
    Leontiskos

    Yes, I think a lot of the questions we're running across are somewhat siderails -- but I don't think it's some fundamental error as much as a difference in approach to philosophy.

    I'm not proposing an intersubjective approach to truth, but to justification, though. At least with respect to beliefs about what is real.

    Okiedokie.

    @Amity -- what's wrong with making them publicly available?
  • What is real? How do we know what is real?
    Well I know exactly what I mean by falsification. Do you know what you mean?Leontiskos

    I'd start with Popper, at least, so falsification follows the form of a modus ponens.

    But then I'd say that in order to falsify something you have to demonstrate that it is false to such a degree that someone else will agree with you. Which states clearly how there's so much more to falsification than mere disagreement, or believing in two different things that cannot both be true at the same time of the same object. That's just believing two different things, so all you need is a notion of belief and what beliefs are about.

    For falsification there's not just beliefs at play, there's an interplay between measurement, theory, and practioners.

    Loosely speaking I'd say that for falsification to take place the two have to be talking to one another in the same dialogue. So Aristotle and Lavoisier serve as a good example specifically because they mean very different things about water while referring to the same. There's no falsification taking place as much as the dialogues are doing different things entirely. Furthermore I don't think that for falsification to take place that the next theory which takes its place will be true or even needs to be demonstrated as true. Rather, it's "good so far, and here are the ways we can test its limits" -- falsification has a whole practice of testing built into it. It's a collective activity, and not just a status between competing theories of reality.
  • What is real? How do we know what is real?
    I think that is so vague as to be saying nothing at all,Leontiskos

    I'd say it's on par with "From the more certain to the less certain"

    For one, I intend the biological metaphor to apply to knowledge: and what was once a good bit of knowledge depended upon the intents of the organism using it, the whole ecology within which it fits and is responding to. Further, life is something of a cycle and the final cycle of life, just like ideas, is death -- eventually the ideas die out because the environment has changed far too much.

    Further, we don't begin with a solid foundation and build outwards. Rather I'd use the plant metaphor that we begin with a seed which, when nurtured in the proper environment, slowly takes roots to the soil and becomes something solid.

    So rather than beginning with the certain I'd say we make random guesses and hope to be able to make it cohere in the long run.

    As above, I don't think this is a theory. Note too that if one thinks "guess and try to make sense" is a viable approach, then they already hold to the idea that reality is intelligible and sensible. They are not starting from skepticism.Leontiskos

    I don't think that follows at all. I think that what this says is that @Leontiskos can't understand how someone could think that sensibility and intelligibility are important unless they are not skeptics, rather than that one doesn't begin with skepticism.

    The intelligible and the sensible are what we deal with -- but whose to say that what is sensible is what is real? That's the question after all. How do we hop from "the intelligible and the sensible" to "and it is real"?

    Sure, and we could add in your new thesis about indivisibility to complicate the picture, but my general point will still hold.Leontiskos

    Well, it's persuasive to you, but not to I.

    Well, is there an argument here? And is it valid? The basis of any such argument is something like <There are more scientists and scientific papers today; therefore metaphysical realism cannot be true>Leontiskos

    Aristotle's method of metaphysics which utilizes science is what justifies his inference from the sciences to support metaphysical truths. At the time one could reasonably, though falsely, believe they had reviewed "all the sciences" such that they could reasonably make inferences about "all of reality at its most fundamental". Today, however, no one person can reasonably, though also falsly, make the statement such that "And now that I've finished reviewed all existent sciences and shown how my views are better I will now move onto the most general truths about being as such"

    Aristotle, though he did not have access to all science, could feel confident that he'd responded to all the worthwhile arguments so that he could link science to metaphysics.

    The sheer volume of knowledge today makes it so that Aristotle's procedure can't be carried out. So one's metaphysical realism can't be on the basis of science insofar that we are taking on a neo-Aristotelian framework -- it's simply impossible to do what Aristotle did today with how much there is to know.

    So the whole "From the more certain to the less..." thing will work for some particular case, but it won't reach metaphysical universality.

    Re: Style -- I can understand him writing the way he does. Where I'm writing out the short version I'm mostly doing the thing where I'm checking myself to make sure I understand the basic message as a sanity check to my understanding. The style makes sense, though, because his justifications for his philosophical moves come from a large number of philosophical concerns and comparisons; the concept simply isn't easy to write about in a philosophically persuasive way.

    Also, great rendition of the prologue. I think a lot of my silence comes from unfamiliarity, so your more thorough synopsis is helping me to think through things better.
