First, I want to commend you for the substantial time and effort you have clearly put into philosophizing. You have managed to put something together which is, on the whole, innovative, and impressive. As to whether or not it does the best job among competing theories by metrics of truth and explanatory power, I hold my reservations. But, I expect a good time investigating it. — Tarrasque
Thanks! I'm looking forward to this conversation too (and enjoying it so far already).
"John believes that abortion is impermissible, while I believe abortion is permissible." This is a statement which makes sense, and would not be strange to hear. In a sentence such as this, do you hold that the use of the word "believes" is a category error? If moral utterances do not express beliefs, how can the above be true or false? Must it be false? How would you reform this sentence to preserve its meaning? — Tarrasque
Natural language is inherently sloppy, and I don't set out to admonish anyone for casually using "belief" to refer to their moral opinions. But because "belief" has descriptivist connotations, especially in the Kantian vs Humean context, I try to be careful to avoid it myself. I say instead that moral utterances impress (and so implicitly also express; you caught the part about impression vs expression earlier?) intentions. And I say that intentions can be objectively correct or incorrect ("true" and "false" also frequently have descriptivist connotations, so I try to avoid them myself, but recognize their casual use). Both intentions and beliefs are subsets of what I call "thoughts" (as distinct from "feelings", "experiences", and other mental states), so the simplest rephrasing of the above would just be to say "John thinks ... while I think ..." instead, since the permissible/impermissible already carry subtler imperative force.
(I want to launch into the next thing I wanted to bring up, thoughts vs feelings or "order of opinion" here, but I don't want to break the flow of this response so I'll put that at the bottom instead).
In general, when not dealing with modalities like that, I would most strictly phrase things as "so-and-so believes such-and-such (to be the case)" for descriptions and "so-and-so intends such-and-such (to be the case)" for prescriptions.
Furthermore, atomic moral sentences can be used to construct valid arguments. Example,
P1. Stealing is wrong.
P2. If stealing is wrong, then getting your little brother to steal is wrong.
C. Getting your little brother to steal is wrong.
If moral statements express beliefs about matters of fact, this is no different from a common variety modus ponens. Otherwise, there is something strange going on here. If I understand you correctly, when I utter "stealing is wrong," I am impressing on my audience some imperative not to steal. This normative evaluation is capable of being correct or incorrect, by your account, but the meaning of the sentence is nonetheless to impress a particular intent. With this in mind, let us semantically dissect the above modus ponens.
In P1, the atomic sentence "stealing is wrong" impresses an intent by its very utterance. This is due to the type of speech-act you claim it is. In a sense, the statement "stealing is wrong" cannot be disentangled from this force of impression.
Yet, in P2, I state that "IF stealing is wrong," then this other thing is wrong. In this case, I am not committing to impress anything on my audience. The meaning of "stealing is wrong" as an atomic sentence appears different than its use as the antecedent of a conditional. This is problematic for the validity of moral modus ponens. Your theory will have to account for this in some way to be successful. — Tarrasque
This is why I brought up the "Socrates being mortal" example before.
In my system of logic, I propose that rather than treating a statement like "All men are mortal" as one proposition and a statement like "All men ought to be mortal" as another, completely unrelated proposition, we instead take the idea that they have in common, "all men being mortal", and wrap that in a function that conveys what we wish to communicate about some attitude toward that idea. For example we might write there-is(all men being mortal) to mean "all men are mortal", and be-there(all men being mortal) to mean "all men ought to be mortal"; and generally, write there-is(S) and be-there(S) for the equivalent descriptive and prescriptive statements about the idea of some state of affairs S, whatever S is. We might wish to use shorter names for the functions, like simply is() and be(), or some other names entirely; I am merely using the indicative and imperative moods of the copula verb "to be" to capture the descriptive and prescriptive natures of the respective functions.
So in your modus ponens, the logical relationship is actually between "stealing happening" and "getting your little brother to steal": getting your little brother to steal entails stealing happening. So if it-ought-to-be-the-case-that-there-is(not(stealing happening)), and (getting your little brother to steal) entails (stealing happening), then it-ought-to-be-the-case-that-there-is(not(getting your little brother to steal)).
You can replace it-ought-to-be-the-case-that-there-is with it-is-the-case-that-that-there-is and you get the same logical relations, just with descriptive force instead of prescriptive force.
Alright, I'm following so far. Whether or not this conception is accurate, I like it a lot. — Tarrasque
Thanks again!
To this point, I will simply offer an alternative explanation. I don't think that "same idea, two different attitudes toward it" captures what is going on in this case. Rather, I hold that these are two distinct ideas. One is that people do murder, the other is that people ought to murder. Somebody could agree or disagree(correctly or incorrectly) with either, in any combination. In accordance with the is-ought distinction, my agreement with one cannot logically follow merely from my agreement from the other. — Tarrasque
I agree completely, and I didn't mean to suggest otherwise. My point is just that the opinion "people do murder" and the opinion "people ought to murder" can both be decomposed into some attitude or another toward the idea of people murdering: one descriptive attitude (the idea does happen) and one prescriptive attitude (the idea should happen). You can totally have different views on each of those full opinions: agree that it does happen, disagree that it should happen. That was the point of using that example, that for most people, I expect their agreement on opinions about the same idea (people murdering) will be opposite for those two kinds of attitude: they'll agree that it does, disagree that it should. Thus illustrating what "people do murder" and "people ought to murder" have in common (the idea of people murdering), and different (the attitudes toward that idea).
I was thinking of supererogatory action when I typed that out, so I'm glad you caught it. While you are correct that "he is obligated to X" is much normatively weightier than "he ought to X," I still think that using "ought" to refer to supererogatory acts is a butchery of our use of the word. If you were to tell me "everybody on the planet ought to live life in constant ecstasy" or "you ought to sacrifice your life to save mine," I would strongly disagree with you. If you then told me that when you used "ought," you really just meant that these things would be good, I would come to agree with you, still believing that you had originally misused the word "ought." I will provide more reasons why I think this below. — Tarrasque
I see this as just another example of natural language being sloppy. I agree that in some cases "ought" will carry connotations of obligation, rather than merely supererogatory good, and that being blithe to those differences will result in miscommunication. But that's something to sort out rhetorically, and doesn't have much to do with the actual underlying logic I'm on about here.
Alright, this is the place where I want to talk about reasons and rationality. In all your theorizing on normativity thus far, I have only seen you touch on moral normativity. This is not the only type. I can make claims like:
"You should stop smoking."(Prudential ought)
"You ought to proportion your belief to the evidence."(Rational ought)
"You ought not to beat your wife."(Moral ought)
"You ought to do the thing that you have the most reason to do."
I would like to touch on that last example a little more. "You ought to do the thing that you have the most reason to do." If you are anything like me, you find that incredibly intuitive. I have come to believe that it is essentially the definition of ought. The thing that a person ought to do is the thing that they have the most reason to do. Moral reasons are a type of reason, but often the thing that we have the most moral reason to do is not the thing that we have the most total reason to do(ergo supererogatory actions).
Since moral oughts are not the only type of oughts we use, I am surprised to not see theorizing on broader normativity in your work. Questions like "Is X rational" or "Is P a good reason to Q" need to be answerable, or at least explainable, by any plausible theory of normativity. — Tarrasque
I see prudential oughts as boiling down to a kind of moral ought. Taking care of yourself is a kind of moral good -- not necessarily an obligatory one, but still a moral one even if only supererogatory, you matter just like everybody else matters -- and instrumentally seeing to moral ends is still a kind of moral good. So you should stop smoking because if you don't you'll probably suffer and die, and people suffering and dying is bad.
Rational "oughts" I think can be better rephrased descriptively. "If you proportion your belief to the evidence your belief is more likely to be accurate." You might ask "but should beliefs be accurate?" and the answer to that is a trivial yes, because believing something just is thinking it's an accurate description of reality. If you didn't care to have an accurate description of reality, you wouldn't bother forming beliefs.
I agree completely that "you ought to do the thing that you have the most reason to do" is incredibly intuitive, but I think that a reason to do something just is a moral imperative; largely because of how prudential self-care collapses to moral normativity on my account.
I do have a lot more thoughts on how to
justify both beliefs and intentions, which I think is more of the rationality-normativity you're thinking of. But that would get way outside the scope of this thread on semantics. I do intend to start threads on them later, and I hope you'll join in then.
In the meantime, here's the bit about order of opinion (thoughts vs feelings) I cut out from above for flow:
The difference in attitude alone isn't enough to account for what I mean by "intention" as distinct from "desire", which both have the same direction of fit, world-to-mind. To explain that, I need to first elaborate on differences in attitude between opinions with the same
mind-to-world fit. More fundamental than opinions are experiences, and an experiences with mind-to-world fit are called "sensations". These are the raw input from our senses, free from any interpretation: the contents of a sensation are colors of light, pitches of sound, and so on, not yet shapes or words. In contrast, the simplest opinions with mind-to-world fit, first-order or irreflexive opinions of that type, are called "perceptions". These are interpretations of that raw sense-data into more abstract representations, but still of the same idea. (An analogy can be made here between raster and vector computer graphics formats, where a raster format stores an array of colored pixels and any shapes that appear in them are merely inferred by human viewers out of the patterns in those pixels; while a vector format stores abstract representations of exact shapes directly, which can then be rendered as arrays of pixels for display. The human viewer senses something like the array of pixels with their eyes, but then in perceiving shapes in the image, they are essentially "vectorizing" the image in their own mind). Further still, higher-order or reflexive opinions with mind-to-world fit are called "beliefs", and I hold that the distinguishing feature of beliefs is that they "objectify" what have thus far been completely subjective opinions, because they are reflexive in attitude, being capable of casting judgement on other opinions with the same content: one can disbelieve one's perceptions, or judge someone else's perception to be wrong as well. A belief is a perception that has been questioned (however thoroughly) and found (however correctly) to be the correct interpretation of sensations, the correct picture to use as a representation of the world, the correct opinion with mind-to-world fit.
I hold that there are analogues to all of those, but with world-to-mind fit instead. I call experiences with world-to-mind fit "appetites". These are composed of the raw inputs of things like pain, hunger, thirst, and so on. While sensations are the experiences that make us feel, on a raw unexamined level, like the world is some way, appetites are those experiences that make us feel, on a raw unexamined level, like the world ought to be some way. I visualize this as building two images, two ideas, in our minds: one of them a picture of the world as it is, meant to serve as a representation of the world, meant to fit the world; and the other of them a picture of the world as it ought to be, meant to serve as a guide for the world, meant for the world to fit. Sensations are those experiences that feed into that first picture, and appetites are those experiences that feed into that second picture. In contrast to those uninterpreted appetites, the simplest opinions with world-to-mind fit, first-order or irreflexive opinions of that type, are called "desires", like the expressivists and Humeans are all about, which I hold to differ from appetites in the same way that perceptions differ from sensations: desires are interpretations of appetites, and while an appetite may have as its content the feeling of, for example, hunger pains, the desire that is interpreted from that will have as its content instead, for example, to eat a burrito; just as sensations may contain patterns of light while perceptions instead contain shapes. And lastly, higher-order or reflexive opinions with world-to-mind fit I call "intentions", and I hold that the distinguishing feature of intentions is that they "objectify" what have thus far been completely subjective opinions, because they are reflexive in attitude, being capable of casting judgement on other opinions with the same content: one can intend other than what one desires, or judge someone else's desires to be wrong as well. An intention is a desire that has been questioned (however thoroughly) and found (however correctly) to be the correct interpretation of appetites, the correct picture to use as a guide for the world, the correct opinion with world-to-mind fit.
It is that reflexivity of attitude that I hold to make an opinion cognitive, apt for being found objectively correct or not, though as they differ in the purposes to which they put their ideas, they differ in the criteria by which they are to be judged correct or incorrect: beliefs are to be judged by appeal to the senses, everyone's senses in all circumstances if they are to be judged objectively, and intentions are to be judged by appeal to the appetites, everyone's appetites in all circumstances if they are to be judged objectively. Intentions are cognitive but non-descriptive opinions; in the same way that perceptions are descriptive but non-cognitive opinions. I like to term cognitive opinions like beliefs and intentions "thoughts", and non-cognitive ones like perceptions and desires "feelings". So when I say that I hold prescriptive statements, moral utterances, to impress intentions rather than to express desires, I mean that they are not simply demonstrating the speaker's present feelings about how things ought to be, any more than descriptive statements are simply demonstrating the speaker's present feelings about how things are. They are instead pushing a considered thought about how everyone should think things ought to be, in the same way that descriptive statements are pushing a considered thought about how everyone should think things are.
