The hotel argument points out the absurdity of infinite material things. If the hotel has infinite rooms and they are all occupied and then a new customer comes the manger can still except new guests. He has infinite rooms. Everytime a new customer comes and can give them a room and move tenet in room 1 to room 2 an room 2 to room 3 etc. Even though every room is occupied he can always except new customers. And even though new customers are checking in he always has the same number of customers. Infinite. 1000 more check in, still the same number of customers. Even if an infinite amount of new customers can he could still accommodate all of them. and he would still have the same number of customers.

Now everyone in rooms with even numbers checks out. Guess what he still has the same exact number of customers; infinite.

The argument goes on and on but you get the point. An actually existing material thing is full of absurdities. It cannot exist.

Yes, but for the argument to work it has to apply not only to synchronic collections of particulars but also to diachronic chains of events states of affairs. So since Craig thinks that God has existed within physical time since the universe existed, and that God but not the universe is eternal, it looks very much like Craig is forced to say something like 'before God created the Universe, he existed outside time,' which is something that is hard to make sense of. Hence the mental gymnastics.


Although, re-reading it, this post looks more like a reply to WWN than to myself, since I haven't so far disputed the first half of the KCA. Was that the intention?

Well, there's the obvious one:

1.) The cardinality of any set is greater than the cardinality of any of its subsets.
2.) To say that God is eternal is to say that God has an infinite number of temporal parts, and no first temporal part.
3.) The cardinality of the set of all of God's temporal parts is infinite. (From 2)
4.) There is a proper subset of the set of all of God's temporal parts which has an infinite cardinality.
5.) 3 and 4 contradict 1.

Since Craig thinks (1) is a logical necessity, and indeed depends on it for the first half of the KCA, and 3 and 4 follow directly from 2, premise 2 must be false. But if so then it's not clear what 'eternal' means.

I don't recall you ever making an argument about types of pleasure, at least explicitly. But even if you had, it's not clear to me that it would be any more difficult to determine the likely causes of those pleasures than the sensual ones.

You have been trying to construe my position as entailing that utilitarians identify happiness with an unmeasurable quantity, but any time I suggest a candidate quantity and ask you to confirm that you think it is unmeasurable, you apparently get quite upset. So frankly I'm at a loss as to what your contentions actually are.

Additionally, there's really no need for insults. I'm starting to think you're using indignation as a cover for your lack of a convincing reply.

The people I don't get are the atheist moral realists, which according to that poll posted, is definitely something that exists in philosophy departments. Why bother? The creation of moral realism was there to save the idea of god from the problem of evil, absent god you no longer need moral realism. I think people just like the idea of their morals being 'objective', because they're taught that subjective = bad and objective = good, which is important for theories of knowledge, but a bad way to think about ethics.

I also think you can solve the problems of utilitarianism if you think of pleasures/enjoyment not as a continuous metric, but as an infinite ordered set of satisfied desires. You can starve 1 to feed 100, but you can't make 100 content by starving 1 - the 'addition' is in different dimensions, and the 'hunger' dimension takes priority over the 'entertainment' dimension. Of course, that reduces some of the appeal of utilitarianism, by getting rid of a single metric of 'utility' that everything can add or subtract from, and you have to go through the hard work of deciding the ordering of those desires, but that classic simplification is what introduces the problems of the utility monster in the first place. Keeping your terms separate is probably for the best.

Yes, but this is a blunting of the verificationist sword - you can no longer say that certain statements about metaphysical states of affairs are meaningless full stop, you can only really say that you are unwilling to accept the axiomatic system under which they are meaningful. Which is more Carnap than Ayer; not nearly as flashy, because you can't go around telling people they're fundamentally and systematically mistaken about what they think they mean when they speak.

That is, it is not the positivists reliance on the principle of verification that is a problem, it is their insistence that it is the only justifiable axiom.
I see your point, and it's valid. I just strongly don't like this idea of importing the issue of self-referential sets into theories of knowledge. How many other systems of morality or knowledge could survive having to justify their own axioms with themselves? Not many, but only the positivists get hit with it again and again.

If we have no logical grounds from which we can tell others what they should and should not do then there is no such thing as morality. This is the OP's point.
Oh, there's an excellent reason for everyone to act a certain way - no society can exist without a shared moral base on the broadest level. Now, the continued existence of humanity and society is not an objective good either, but humans including me unsurprisingly tend to agree it's a subjective good. A lot of subjective beliefs are shared by most people and are very important to us but in the end they're not really any more objective than liking a color. My conclusion that they are not objective doesn't make them less important or valid to me.

Any argument that concludes that morality doesn't exist is patently false as all people indeed hold morals, whether they have any supposedly objective basis for them or not.

I think I don't understand the historical/teleological claim here - plato was certainly a moral realist (in that he thought value-laden things like The Form Of The Good take, actually existed), but it'd be a stretch to think that he was reacting to the threat of atheism. Maybe you're thinking of something in particular?

Anyway, even if it turns out that moral realism was invented to fulfill a purpose that atheists have since given up on, but this doesn't obviously bear on the question of the truth or falsity of the position. Plus, if I can name-drop Plato again, a lot of people think that the Euthyphro dilemma shows that theism is actually a major threat to moral realism as it's normally construed.

In contemporary philosophy, there are something like five major ethical theories in play: consequentialism, deontology, virtue ethics, contractualism, and divine command theory. Only the last of those depends on a deity, and even that one can be thought of as a species of a more general command theory, in which moral facts depend on the commands of some group or individual, divine or otherwise. The vast majority of published work in the field of ethics makes no mention of God at all.

Yeah, could be. I have no major objection to this version of utilitarianism. But there are a lot of ways to formulate a utilitarian theory. I'm not actually an expert in ethics, but I think some of my ethicist friends have said something like this maybe.

Subjective morality clearly exists, that's true. But it provides no grounds from which one can hold others morally accountable. If our subjective moral beliefs clash then there is nothing to be done because neither of us are right or wrong since there is no objective basis from which those moral beliefs can be judged. Shared subjectivity does not make it any less subjective. That your subjective beliefs are important does not give you any right to hold others accountable according to those beliefs. Holding others accountable for your subjective moral beliefs is just as absurd as claiming that everyone ought to like the color orange because you like the color orange. The point is not that morality does not exist as a concept, it's that if morality is only subjective belief then no one is in any position to hold others morally accountable, which is the entire point of morality.

I very much doubt the existence of a higher power from which we can obtain objective morality. So the problem of subjective morality is a problem for me as well. But pretending that it isn't a problem does nothing to solve it, it merely makes you (seem?) delusional. The idea that subjective beliefs can hold sway over others is pretty much the basis of totalitarianism.

In my opinion there is no such thing as true objectivity. What we call objective is simply the agreement of many subjectivities. However, if the universe has an infinite creator it would seem that creation would be an objectively real thing. That creator would also be responsible for creating morality since it created everything and thus morality would be objective. Infinity is a difficult concept for human beings to wrap our heads around, but I think one way of explaining what I'm trying to say is that an infinite subjectivity would be objectivity by virtue of its infinite-ness.

God 'creating morality' doesn't make sense to me either. Pretty much everyone thinks that moral facts supervene on the totality of the physical facts. If that's true, then a hypothetical deity could no more make a physically identical universe with a different distribution of values than they could (e.g.) make a physically identical universe in which the theory if evolution is false.

If you think that objective morality has to be something totally independent of the physical universe, then I can see why an atheist would have to be skeptical of it, but almost nobody thinks that.

Please don't take my words out of context. I told you exactly what I believe objectivity is. The nature of experience is entirely subjective, and since experience is all that we can possibly know, feel, be aware of, etc. then if objectivity exists we cannot know it. We cannot know facts about things in the world, we can only know facts about our experiences, but that it seems that we experience things outside of ourselves does not mean that we actually do (i.e. Kant). This is simply the nature of subjective experience, and when a bunch of them agree on something we call it objectivity because it's more comforting to believe that we know something objectively than accept that we can't.

Most of us are naive realists about the objective world for practical reasons, but logically there is no bridge to get from subjective experience to objective reality. So to borrow your words, subjective facts about an individuals experiences are all that that individual can know by the very nature of subjectivity and experience.

We do not disagree on this point. It simply means that there is a logical problem with claiming that a subjective belief should hold for all, some, or even a single other person. Practically, it clearly works well.

Granted, a deistic creator would merely put us in the same situation we are in now. But you missed the most important point regarding a theistic creator, that of being infinite. If a theistic creator existed and was infinite then that creator would be objectivity itself.

Okay, yeah sure: universal radical skeptics have ground for refusing to assent to any objective theory of ethics. But it also means that you are barred from assenting to any conclusions from e.g. the natural sciences. I suspect that if a moral realist gets an interlocutor to agree that moral facts are on the same epistemic level as physical facts, they'd count that as a win.

'Radical' in the sense of "All knowledge is illusory, pull it up by the root!"

Anyway, logical inference goes two ways and your modus ponens is my modus tollens. I tend to think that if out turns out that some philosophical position leads to the conclusion that nobody knows anything, that counts as a reductio against that position. The a priori insistence that nothing can be known is a surefire way to shut down a conversation. Like, I could reply to any post in D&D (or SAL even) saying "You don't know that! Nobody knows anything!" And it would be about as interesting and relevant as it is here.

But, you know, Duhem-Quine and 'come what may' and all that. The most I can do is show that your premises lead to something ridiculous, but if you are determined to accept that conclusion anyway, there's not really anything I can do. Oh well. (Though I suspect you will not have the courage of your convictions, and will, at some point, claim to have knowledge of something).

I never claimed that nobody can know anything and I've already claimed that I know things. I don't doubt that other people know things too. We all have a great deal of subjective experiential knowledge. That is the only type of knowledge that we can have. And when many subjectivities agree on what counts as experiential knowledge we call it objective knowledge.

I think that the external world exists. I think there are things in the world which correspond to my experience of those things. Can I know that with any logical certainty? No. That's simply a fact. Do I believe that knowledge doesn't exist simply because a logical bridge between subjectivity and objectivity is not possible? Of course not.

We can know facts, even facts about objects, but those facts aren't objective, since we can't be certain about them.

Is that a fair rendering of your position? Because if it is, it looks very much like you're mistaking certainty for objectivity. Alternatively:

Second Guess posted:

We can know facts, but not facts about objects, only facts about our conscious experience. So we have knowledge, but not objective knowledge.

This doesn't involve a terminological confusion, but it does entail solipsism. Because on this account what you know is something like "I am presently having an experience as of someone talking to me," but you absolutely do not know anything like "Someone is presently talking to me" or even "That, over there, is a person." You might think that we infer the latter from the former, but that we lose certainty along the way. So we know that 'This is a person' but we aren't certain about it. But this is the same conclusion we got from the first guess: we have fallibile objective knowledge. To deny that this is really objective knowledge is, once again, simply to confuse certainty and objectivity.

So it looks like your position either depends on a terminological confusion, or else it entails solipsism.

Finally this is all ignoring the fact that whichever of these positions you're prepared to endorse, the problem you're pointing out isn't unique to moral facts; it generalizes to all knowledge. If the most you can say about knowledge of moral facts is that I can be no more certain of it than I am that I have two hands, then that looks like a pretty weak argument against moral realism.

Before I address your questions, do we agree that solipsism is the necessary logical result of subjective experience? If not, then we're both wasting our breath because that logical conclusion is the basis of all I've been talking about so far.

For now I will assume we agree so as to answer your questions. Your second guess is correct. But this is not "fallible objective knowledge," it is subjective knowledge. As the guess implies, if objective knowledge exists or is possible it is not so for human beings. It certainly entails solipsism. Subjective knowledge is the only type of knowledge human beings can possibly hold, by the very nature of human experience.

For a thing to be objectively real it must exist regardless of whether or not a subjectivity experiences it at a certain point in time. Objective reality is true independent of our subjective observations. Yet, all we can know are our subjective observations. So we cannot know anything objectively, since objective reality is dependent upon being true without subjective experience of it and we cannot know anything without subjectively experiencing it. If you believe that human beings are capable of knowledge without subjectively experiencing it, I would love to hear the insane argument supporting this idea.

It seems to me that a logically sound or valid argument that shows that objective knowledge is not possible would be quite a strong point against moral realism. But we don't seem to agree with or understand each other on any other topic, so why change that dynamic now?

I'm saying that there is no logically sound argument that can show that we are capable of having objective knowledge of anything. This logical fact does not negate the fact that normal human experience makes the existence of objective reality extremely intuitively accurate. The strength of the logical argument regarding subjective experience and objective reality, coupled with the strength of the intuition that objective reality exists, means that naive realism is a reasonable philosophical position and one to which I ascribe.

There's a difference between morals being subjective, and that there exist an objective morality that is inherently unknowable. It technically wouldn't undermine moral realism, you'd need something else. Though I suppose you could say that, just as atheism is the pragmatic choice for when you lack knowledge of God, moral realism is therefore not useful in the same way. But I think the argument against moral realism can be made a bit stronger than that.

Couldn't you then contort any "utilitarian" argument to individual ends based on how you order those desires? Why bother with the contrivance of utilitarianism at that point?
That already happens. Take the colosseum example. with a continuous metric of happiness, there must be some number of people watching that would counter balance the people suffering - what that number is depends on how much you value each of the experiences involved, what the numerical relationship would be between them.

All moral systems are contrivances, I guess is the point. But that's okay :)
Well, all historical narratives involved in philosophy are a little fast and loose with the truth. I guess that's my bias showing up, because that's how it's treated in Abrahamic faiths. Greek pagan religion had no problem showing Gods as callous and capricious entities, which I presume you can judge for yourself. In systems with an unquestionable good deity, you need to deploy moral realism at some point, just to save His skin. You absolutely do see it in religious debates In The Wild, as it were.

This is the point many people lose their poo poo over. ~morality~ is not supposed to be some practical thing decided upon by mere mortals that could be changed, it's supposed to be an immutable law of physics that applies to everyone ever in the same way.
