    PSR - for every fact there is an explanationRussellA

    Ok, let's hear about this first. What is the explanation for "for every fact there is an explanation"?
  • In defence of the Principle of Sufficient Reason
    On the one hand "light bends around sources with high mass due to gravity" and on the other hand "gravity causes light to bend around sources with high mass".RussellA
    This sounds like a contradiction. Surely PSR doesn't allow contradictions for the conclusions.

    In the same way that "the reason he is ambitious is because he is driven" and "the reason the job was complex was because it was complicated."RussellA
    These are just repeating the same thing for what had been said in the first part of the sentence using because. It is not saying anything new or different.

    "Gravity" is more a synonym than a reason why light bends around sources with high mass.RussellA
    Gravity is a scientific concept which must apply to every cases in the universe if it is true.
  • How do you define good?
    Isn't it the case that good cannot be defined in morality? Only the human actions are good, neutral or evil. But good itself is a word for property of the actions.
  • An evolutionary defense of solipsism
    The question does not answer itself. It implies that mind without body is an unintelligible assumption, which generates the vacuous assertion. It asks if solipsism would make more sense if it assumed mind in body.
  • In defence of the Principle of Sufficient Reason
    In a sense it does, as light bends around sources with high mass due to gravity.

    From www.astronomy.com

    While it is true that photons have no mass, it is also true that we see light bend around sources with high mass due to gravity.
    RussellA

    Doesn't it then disapprove what you are claiming? Gravity is a force when the high mass pulls any mass lower than the high mass. But the light bends around sources with high mass due to gravity. Even massless photons gets bend due to gravity means gravity applies to even massless matter.
  • In defence of the Principle of Sufficient Reason
    we just have to accept our observation that gravity causes a rock to fall to the ground when released, where gravity is something that causes a rock to fall to the ground when released.RussellA

    When the light is released into the space, why doesn't it fall to the ground?
  • An evolutionary defense of solipsism
    My purpose is to try and figure out what's going on. And 'solipsism' isn't trying to prove anything. It's a thesis. I am the prover. And I'm not really trying to 'prove' it, just show that it is a simpler thesis than its nearest rival. Whether that proves it - that is, puts its truth beyond all reasonable doubt - is another matter, as simplicity is only one epistemic virtue not all of them.Clearbury

    Why not solipsism with the mind in a body, or mind and body? You keep emphasising on simplicity, but simplicity can degenerate into the vacuous assertions.
  • In defence of the Principle of Sufficient Reason
    Principle of Sufficient Reason (PSR): For any thing that exists or is true, there is a sufficient reason for it to exist or to be true.A Christian Philosophy

    Isn't reason a product of human mind? Reasons don't exist out there in the external world. There are only matter, energy and changes in the world. Reason is an operation of human mind seeking for the causal explanations on the existence and changes.

    For the proper operations of the inductive reasoning, human observations do need the data to draw the reasoning for the conclusions.

    Therefore there are many events and existence which have the reasons, and many are unknown due to lack of the data.
  • The universality of consciousness
    If individual consciousness does not exist besides our own, that does not disprove the existence of others’ consciousness. In fact, it gives evidence to the opposite. The creation of other people by one’s own mind means that those people must, then, have a consciousness, that consciousness being your own. Likewise to the characters in dreams, if we assume other people are also creations of our mind, to say that they do not have consciousness is to deny the existence of one’s own consciousness, as the actions of those people are a direct result of your consciousness.Reilyn

    I know other people's consciousness exist by my perception of their bodies, language they speak which reflects their thought contents, feelings, emotions and dispositions. Their facial expressions can be also the sign of their consciousness, which can give clues to their mental states. But when someone is far away in the remote place not visually perceptible, their writings I read can be the proof of their existence in body and consciousness.

    Without above evidence, it is not possible for me to know the consciousness of the others exist. This is the way existence claims its reality in the real world.

    Folks I see in my dreams are as you say, mind-created existence which only exist as mental images in the mind.

    Folks I think about such as the philosophers in history e.g. Plato, Aristotle, Spinoza, Leibniz, Kant ... etc would be the abstract existence who exist in the mind, but not in the real world at the present time now.

    I cannot know anything about the consciousness of the folks in the dreams and abstract world whether they exist or not. I suppose they don't exist.

    So, just assume a mind in a mental state. Now assume the mind has one disposition: to put itself in a mental state that closely resembles the one it is already in. So, its disposition is just to replicate the state it is in but it makes small changes every time it does this. That gets the job done. That's what this is (or could be).Clearbury

  • How do you define good?
    This is analogous to if there was an OP asking where to begin studying what is red, and your response is to say “analyze red trucks”. One should not begin with an analysis of what can be predicated to be red (like a red truck)—viz., happiness—but rather what does it mean for something, in principle, to be red at all? That’s where begin. — Bob Ross


    Your response was to say:

    You are still missing the point. I never said happiness is Good. I said, actions which brings happiness is Good. — Corvus


    Thereby trying to evade my critique by providing the rejoinder that it was a mischaracterization of your view (because you do not believe happiness is good). I, then, responded with:
    Bob Ross

    This is not true. This is your distortion on my point. I wrote about "happiness is not good, but what brings happiness is good". That doesn't mean happiness is not good quality of mind. It means happiness is NOT IDENTICAL TO good. Happiness and good are not the same thing. Happiness is a mental state and Good is a moral value which can cause happiness.

    I am not sure if you were confused between happiness and Good, or your writing was intentional distortion on my points.

    For the concept of Red, you don't learn the concept of Red by analysing what red means. You learn what red means by looking and seeing the red objects. So here is another gross misunderstanding on your part.

    Just like the concept of red, you don't learn what the concept of Good is by analysing it. You learn the concept of Good, by seeing the good acts of humans in the moral situations.

    I think I already wrote in my previous post somewhere. I looked into many philosophers in history for their idea of moral good. They are different, and there is not much content in the description what moral good is.

    For example, Spinoza said moral good is pleasure, evil is pain. And Kant must have said something different, so did Leibniz etc etc. I was not quite sure why you insisted on starting defining Good in building someone's moral code. That doesn't sound like making sense at all. Even if the OP's title is about How to define Moral Good, you should have said moral good is undefinable, like Moore said 100 years ago.
  • The Nihilsum Concept
    I do see now how this Nihilsum doesn't actually provide anything for thought for lets say theoretical abstraction because it has no base at all, thus not very 'useful' or positing anything to our being and not. I also don't even think I understand it anymore or if I did, I think so but it expanded itself.mlles

    You need the concrete logical arguments with evidence based on the rational reasoning to put forward your ideas. But if you deny the logic and reasoning, then you have no feet to stand on to make your ideas and claim objective and acceptable.
  • How do you define good?
    Thereby trying to evade my critique by providing the rejoinder that it was a mischaracterization of your view (because you do not believe happiness is good). I, then, responded with:Bob Ross

    This sounds incredibly obtuse and irrelevant. My point was defining good wouldn't make one morally good, or more morally sensitive person. Rather, being able to reason what morally good actions are in the real life situations, which brings happiness to all parties would be more practical way to be morally apt person.

    You are talking about something totally different in some other planet, from what I am talking about.
  • How do you define good?
    E.g., "where did you get that idea?": I don't know, maybe when you literally said it?Bob Ross

    Happiness is a state of mind, which is the purpose of life. This idea is from Aristotle, which inspired me to follow.

    My point is simple, and precise. There is not much complication there.
    Morally good actions bring happiness to all parties involved.
    Happiness is a state of mind, which is the purpose of life.

    You could further analyse what happiness is. We could say happiness is a mental state of mind, which is good and satisfactory. Good here is different from moral good of course. A good mental state is the opposite of a bad or unpleasant mental state, which is totally different from moral good.

    I couldn't believe when you asked, can happiness be not good. I don't think I have implied or suggested that happiness is not good. Happiness is always good.
    Good here is the quality of the mental state, which is happiness.

    Moral good is the quality or value of some human actions when performed out of the moral duties and practical reasoning.

    This explains exactly why your position is so muddied and convoluted. Instead of providing a substantive response, you just noted that you have absolutely no clue what I am saying.Bob Ross

    You seem to have some fixed ideas of your own on all these questions. But you asked the questions just for the question begging purposes, it appears. It seems to be the case that your questions were not to clarify the points, but to negate the replies as soon as they were sent to you. They are the typical case of question begging.
  • How do you define good?
    You did: are you trying to troll me? That’s literally what I responded to, when you said:Bob Ross

    I was explaining to your question. When you say good actions make you happy, then the good actions were the cause for your happiness. You can be happy without any cause at all from your emotional state of the day. Hence good can be many different things depending on how you use it in the different situation.

    You seem to be too over sensitive on reading the philosophical explanations, which are meant to offer you the simple explanations to your questions. It could be the case that you might be injecting too much emotions into the interactions on what supposed to be objective and rational discussions.

  • How do you define good?
    So, under your view, it is good to do things that make you happy; but not good to be happy?Bob Ross
    If it is good to do things that make you happy, then you are good to be happy. There are many different ways good can be used.

    My critique did not presuppose that there is an abstract object of The Good. Predicating happiness as being good is analogous to predicating actions (that produce happiness) as being good. You can just swap the parts where I said “happiness is good” for “actions which bring about happiness are good” in my critique, and it all still stands.Bob Ross
    You seem to be trying to make things more complicated than necessary here.

    That is a non-sequiture. Moore is talking about the property of goodness, just like you. Moore is not saying that goodness is undefinable because there is no abstract object for it.Bob Ross
    I was pointing out what looks like the source of your misunderstanding.

    That implies happiness is a good thing; which you denied above.Bob Ross
    Where did you get the idea? :D Who on earth would deny happiness is good? Happiness is the purpose of life, according to Aristotle.

    “Good” is the concept of, roughly speaking, what ought to be: what you just described is the concept of ‘moral good’.Bob Ross
    I was looking into various philosophers' concept of Good, but there weren't much in them. One thing noticeable was that the concept of Good was all different in the different philosophers. Beginning with the concept of Good seems to be a not good idea in studying Ethics. Maybe you could come up with establishing the concept in the middle or later stage of reading up Ethics, if it is your topic of interest.

    You don’t think that it may be, under certain circumstances, immoral to go out for a walk?Bob Ross
    Depending on the situation, it could be. It was just a simple example to help you understand the principle.
  • How do you define good?
    It is putting the cart before the horse to begin with what can be predicated to be good, when one hasn’t analyzed what goodness is itself. Do you disagree?Bob Ross

    Yes I disagree. The horse want to have a free run by himself in the field, but you keep insisting putting the cart onto him.

    Good cannot be found until you have performed some actions first.

    Not all actions are moral actions of course. If you went out for a walk or dropped off by the shop, that is not moral action category. But if you helped out an elderly crossing the busy road for her safety, then it is an action performed in moral category.

    From the practical reasoning, you would have known the action was morally good. It brought happiness to all the parties involved in the action, and it would be judged as morally good when the action was performed out of pure duty to bring happiness to the society, the elderly and yourself. This is how moral good operates and means. There is no some matter called Good out there for you to define what it is.
  • How do you define good?
    This was my main point that you keep dismissing without any response: happiness is good is not a description whatsoever of what goodness is. It is not an analysis of the metaphysics of goodness. When you say it “was [a] good enough definition”, that is patently false; because it was not a “definition” in any of the two senses of the term that I used before (or anyone uses).Bob Ross

    You are still missing the point. I never said happiness is Good. I said, actions which brings happiness is Good.

    I thought my point in my previous posts were clear. Good is not an entity. It is property or quality. There is no such a thing called Good. So Moore was right, it is undefinable.

    Only human actions are good or not good based on the fact that whether the actions brought happiness to the society, the parties involved and the agent.

    Until actions are performed, and analysied based on the above criteria, there is no such thing as Good. Good is the quality of some human actions.
  • How do you define good?
    Show me where I ever said that we can “define” good in this sense. Never once. I even referred you to an earlier post I made where I explicitly stated that the concept of good is absolutely simple and cannot be properly defined.Bob Ross

    OK, it is not an important point anyway. Just was trying to clarify the murky points you raised in this thread. It is not the main focus of this OP either.

    I feel that my explanation for Good as the actions which brings happiness to all involved parties meeting at the mid point was good enough definition, if you really insist that one must start from a concept of Good.

    If you feel that is the way you want go, and wish to present your concept of Good, by all means, go ahead after consulting the OP on the matter. I will stand aside, and add my opinion, if any crops up.
  • How do you define good?
    Where did Moore say that?
    I found my old copy PE, and had a quick scan of the book. Moore says something like this,

    "Who right minded folk would ask what Good is unless for lexicographical purpose? .... Good is good. It is undefinable." (PE, pp.6)

    You seem to think Moore had started with a concept of Good in PE, which is a misunderstanding of the original text in PE.

    I have maintained from the beginning of this discussion thread that I think Moore was right that good is an absolutely primitive and simple concept.Bob Ross
    Your writing above seems to suggest Good is definable from what Moore had said about Good. Good is an absolutely primitive and simple concept. When Moore said Good is an absolutely primitive and simple concept, he didn't mean that it is a definition of Good. He was just telling about the nature of Good.

    How can you define good when it is not definable? It seems to suggest you don't understand what you have been maintaining, and are self negating yourself.
  • An evolutionary defense of solipsism
    The issue does not seem to be what kind of a thing the mind is. It does not matter for simplicity's sake whether minds are material or immaterial. What make the thesis simple is that only one kind of a thing is posited - whatever kind of a thing a mind is - and only one instance of that kind of thing is posited.Clearbury

    Another problem with disembodied mind is that, it is devoid of all the sensory perceptions, which is the source of thoughts, feelings and sensations on the external world. It has no linguistic apparatus either which is closely linked to logic and reasoning. All it could do is dreaming, but dreaming is only possible via brain. With no bodily organs available to the mind, we wonder how it could even dream, imagine or even have illusions and hallucination.

    The OP title says it is "an evolutionary defense", hence some counter arguments is being presented against the OP's assumptions.
  • How do you define good?
    Nothing was corrected about what I said: I refer you back to my response. I have maintained the same position throughout this discussion, and you are merely confused about Moore and my claims (as they relate thereto) because you haven't read him.Bob Ross

    In fact, you are absolutely right that he considered it an absolutely simple and primitive concept; and I am inclined to agree with him on that point.Bob Ross

    Well you have agreed with my point succinctly in your post, but then for some mysterious reasons you seem to have changed your mind again.

    Now I agree, that this discussion is a waste of time.

    :roll: I find it interesting that the person who has never read Moore, who doesn't see a need to, thinks they are understand Moore better than someone who actually has.Bob Ross
    It seems to be the case, that your reading the original text was not very through or accurate. The academic commentaries are for helping you to understand the original texts better, and they could correct the misunderstandings you make from your readings on the original texts. They are not being written so that they can be ignored or treated as not useful. Therefore I would advise you not to ignore the academic commentaries and introductions to the topics and original texts.

    This conversation is a waste of my time.Bob Ross
    I thought it was not a waste of time at all, because it helped someone to correct his misunderstanding on Moore. :D
  • An evolutionary defense of solipsism
    I think you have missed the point. Posits are not expalined, that's what makes them posits. Positing two things is more complicated than positing one, other things being equal. thus, I posit one thing - a mind - and I see how far I can go with it.Clearbury

    Your idea of mind seem to be coming from some sort of dualism. That's fine. But my idea of mind is based on the mind as a function of body. That means mind without body is impossible. As soon as body dies, mind dies also by necessity.

    In this situation, the question naturally arises, and need to be explained i.e. how mind can exist and operate without body. This is a quite complicated process I would imagine.

    If the mind without body arguments keeps going on without clearing the inevitable question first, then it would sound like a paranormal rants. We want to avoid that.
  • How do you define good?
    In fact, you are absolutely right that he considered it an absolutely simple and primitive concept; and I am inclined to agree with him on that point.Bob Ross
    It is good that you admit your misunderstanding Moore, and your claim was wrong. :cool:

    “Ethics since 1900” was not written by Moore. If you want to understand Moore, then you need to read The Principia Ethica:Bob Ross
    Warnock was a professor of Philosophy, and the book is a good introduction to modern Ethics. I don't think you need to read The PE, in order to understand Moore, unless you are specializing in his Ethics.

    That’s all fine: the OP is about where should a person start. Do you think they should just skip over asking themselves “is good definable?”? Do you just want them to skip that step?!?Bob Ross
    I am easy with that. If you think the concept of Good is intensely relevant to the topic, by all means carry on with unfolding and elaborating on it. Your question on whether to skip the step should be asked to the OP, not me.
  • An evolutionary defense of solipsism
    For example, the claim that, other things being equal, we have reason to believe a simpler thesis is true, is itself a self-evident truth of reason (or 'apparent' one, as we shouldn't rule out the possiblity it may be false). So, the assumption that the simpler thesis is true is more reasonable than the assumption that the more complicated theory is default true.Clearbury

    Mind without physical body assumption is not simpler than mind with body, because you must explain on how the mind ended up with no body. How can mind operate without body is far more complicated than starting with mind with body which is empirically and logically natural and sound.
  • How do you define good?
    And your response to them was to suggest starting with analyzing happiness; when that is clearly not a good starting point for metaethics.Bob Ross

    I don't think I said to analyze happiness. I said what brings happiness to all parties involved is good. So it was an inferred definition of Good.

    If you ever read any Ethics book, most of them start from the story of Socrates who asked, "How should we live?". He doesn't talk about what good is. No one really starts with what good is. Because like Moore said, and I agreed, good is not an entity. It is a property and quality. It is not possible to define what good is, according to Moore.
  • How do you define good?
    I was talking about the concept of good, and of which one must have an understanding of before they can accurately assess what can be predicated to have it. This is a classic mistake that Moore rightly points out: ethics starts not with what is good, but what goodness even refers to---whereas, most people do it in the opposite order (or merely engage in the latter).Bob Ross

    Where did Moore say that? From my memory, Moore said it is impossible to define what good is, and one must start from what one ought to do from the knowledge of what morally good actions are, rather than asking what good is. (Ethics since 1900, by M. Warnock)

    If it is from the actual reference from the original texts and academic commentaries on these points, you should indicate the source of the reference with your claims.
  • How do you define good?
    You misunderstand me: the concept of good refers to whatever 'good' means, not what or how one can predicate something to have it. Viz., the concept of value does not refer to what may be valuable. One must first understand, explicitly, what 'value' even means, not just as a word but as a concept, to determine what has it.Bob Ross

    You seem to be unaware of the fact that there are hundreds of different concepts of moral good depending on which theory you are looking at. Whatever definition you choose as your definition, it wouldn't be the only one, and definitely not the final one either.

    I have given out the inferred definition from Aristotle's idea. It is clearly saying what moral good is, even if it sounds indirect and informal.

    It wouldn't be right to force down a randomly selected concept of moral good to someone who is looking for a basic method to build the moral code.
  • An evolutionary defense of solipsism
    Yes, I think simplicity demands it must be a mind without a physical body, as a physical body would be less simple than a mind that had no body.Clearbury

    The OP is based on the assumption, it claims, but assumptions are only accepted as reasonable and intelligible when it makes sense or is supported by evidence.

    Assuming mind without physical body is not a reasonable assumption, when it is impossible to imagine mind without its physical body empirically, medically, biologically, and scientifically.

    If you read my post again, it would be clear what the concept of moral good is from Aristotle. Good is a quality or property of actions which brings happiness to all parties involved.

    If you are interested in the wider concepts of good, there are plenty available on internet searches. But is the OP asking for the concept of Good in general? It doesn't appear to be. The OP asks where to begin

    One example of greed is not a sufficient reason for all pleasure senses to be defined as sin. Pleasure senses are also vital factor in survival for the bodily and psychological well-being for the biological agents.

    When you said, "opposite of sin is God", at first glance, it sounds abstract. People would wonder how God could be opposite of sin? But when they think about it further, they immediately would realise that is nonsense, illogical and unintelligible. Opposite of sin could be many different things. No one really would know what you mean by the statement. Defining God is identical with opposite of sin, and saying God is proven sounded absurd.
