What's the difference between determinism and fatalism?

One way may be to describe the difference in counterfactuals. Fatalism is the thesis that had things been different at some time t, it still would have occurred some event (here we may or may not want to see this event as a token or type, it may not matter) at a later time t'. Determinism has this as a vacuous truth since it could not have been different at time t because events at time t is determined by the events in some previous time and the laws of nature.

The parable of Jesus

Many secular people who admire the story of Jesus will point out that it is a moral parable. It is the story of someone that gave his life for the sins of others and was kind despite the huge costs incurred to himself. It is about redemption. But can our sins be redeemed by punishing someone else, even someone who is purely good? It seems immoral top punish innocent people on behalf of the guilty. Sins don't seem to be transferable. Sometimes some minor sins are for example, fines can usually be paid by the friends and family of the guilty and thus, the guilty incur no harm as a result of the punishment. We seem to have no problem with that kind of transferability of punishment. David Lewis wrote an interesting paper on the topic called Do We Believe in Penal Substitution?. I personally find the redemption parable uninteresting and quite morally barbaric. Punishing a good man for the sins of the sinful seem to be a immoral act.

That aside, however, I believe that there is an alternate interpretation of the story that warrants moral attention. I make an analogy to the ubermensch of Nietzsche. The ubermensch is someone that would choose, out of his own will, a life of great challenge and struggle, if only to exercise his strength, courage and engage in a creative life if only for the sake of the challenge. There is triumph in the struggle and it's more important in Nietzsche's scheme of things to live a beautiful but tragic life than a happy or pleasant life if the later life does not offer the opportunity for struggle and greatness. The virtues of strength and courage and creativity are paramount for Nietzsche. Being all powerful might even prevent someone, say a god, from living such a great life because omnipotence forbids the possibility of true struggle and the exhibition of heroic courage which comes in the face of one's own peril when one struggles against something greater than himself. This is why Nietzsche always thought the Roman Stoic philosopher Epictetus's claim that the gods have good reason to be jealous of man to be insightful and true. This is one kind of paradox which I will call a "paradox of omnipotence." Jean-Luc Godard explored another similar theme in his Hélas Pour Moi. In this film, God takes over the body of a man in order to seduce his wife. It seems that only a man, in all his finitude and imperfection can truly win the love of a woman. A god may manipulate her or coerce her into loving him but he cannot win her love the old fashioned way, i.e., through charm, conversation, etc, all the mere mortal appeals.

Now let's imagine a perfectly moral being. He happens to be all powerful as well. Now I suggest that there is a similar paradoxical limiting of one's virtues by being omnipotent in moral virtues as well (instead of the Nietzschean virtues of strength, courage, and creativity which are not traditionally thought of as moral virtues). How does being omnipotent limit oneself here? Well, it seems to me that only the mortal, the finite, are truly capable of things like moral courage, free will, moral responsibility and so on. An all powerful and all good god cannot be truly morally courageous (what has he got to be justifiably afraid of? What can possibly harm him?). Courage is the overcoming of justified fear through strength of character and will. Without the possibility of justifiable fearing anything, courage is impossible. God may only be "courageous" in a irrational sense that he overcomes an irrational fear. God can seem to do no wrong either and may not seem to have a choice in doing evil as he is determined by his omnibenevolence and his other attributes.

Thus it seems to me that God, or any moral ubermensch, if he is truly all powerful and all good, would necessarily choose to limit his powers by some kind of incarnating himself into mortal form and suffer through the (moral) trials and tribulations of someone that is put into dire situations to test and practice his own moral virtues. This would then be a parable to show that the possibility of being truly good and decent necessarily rests on our finitude. I think that this is an extremely far fetched interpretation of the Bible and it is likely not how it was intended to be read by any of its writers. But for me to see any value in the Bible at all, with all its barbarity, I would have to see it this way.

Possibility does not entail any degree of probability

In the previous post I noted that I think Wittgenstein was trying to make the point that the mere raising of a possibility counter to common sense does not offer us a justified reason to put that common sense into real doubt of any degree. Real doubt requires more than mere raising of alternative (logical or otherwise) possibilities or the feelings of uncertainty which may result from it. One example of possibility not entailing any probability is this:

Consider the unit line (length of 1). It contains a continuum of numbers from 0 to 1, inclusive. Choose any arbitrary number on that line, say, .333.... There certainly is a possibility that a random selection of any number from that continuum will be .333...; after all, .333...is a number between 0 and 1. But what is the probability that it will be that number? The answer is literally, 0.

So in this case, even though there is a possibility of it landing on that number, there is no probability of it ever doing so. Our confidence in it landing on it, if it is to be rational, to to assign it 0 confidence.

Wittgenstein's examples, I believe, used real life possibilities instead of this mathematical example.

My reply on a blog

Here's my reply to a blog's post about Wittgenstein's On Certainty.

I think it quite a naive reading of W’s On Certainty to say that the Moon Landing was a refutation of his views. Keep in mind that, as a young man, W was a year away from his doctorate in aeronautical engineering and he probably was well aware that someday, maybe even in the near future, people would walk on the moon.

Let me just say that I believe W’s work on doubt to be very insightful and even correct. I may be taking some exegetical liberties in my interpretations but such liberties are justified when dealing with W because he was such a horrendous writer. Horrendous writer may be but I still find many of his ideas quite profound though, as with you, I also think that much of his esteem among many philosophers to be from his “bewitching” personality as opposed to the quality of his views.

This is how I interpret those passages. W was making an analogous move to Gettier in his seminal work on knowledge. As Gettier showed that justified true belief (JTB) is not necessarily a well defined and philosophically robust definition of knowledge but may be loosely termed such, W showed that just by raising possibilities counter to some forms of common sense is not a philosophically relevant form of doubting.

Gettier showed that it takes more than just JTB because the justification criterion must occur in a certain way. It can’t just be any ol’ sort of justification because one can be justified in some belief coincidentally. W’s example of being correct about dreaming and being on the moon, I believe, is meant to show that same point as it relates to doubt.

Mere raising of possibilities such as the possibility that one is now dreaming or being on the moon yesterday when one doesn’t believe oneself to be does not destroy one’s belief or even certainty in such beliefs. W’s reasoning for this conclusion as is detailed is by several examples and arguments.

He argues that raising odd possibilities tend to cancel out. For example, the possibility of someone being on the moon in 1949 (when On Certainty was written) when he tells you that he was is more than canceled out by the possibility of his being crazy or by him using those words in a way that you have misunderstood him. He could be in a different linguistic context than what you presume him to be in of speaking truthfully (such as sarcasm, telling a fictional story, etc) or he could be speaking in a language you don’t even understand. These unlikely possibilities cancel out any such *even more* unlikely possibilities of someone being on the moon in 1949 (which was impossible given the technology of the time). Raising of mere (logical) counter possibilities does not entail one should justifiably lower the probability of any belief as doubt would require. This was, I think, W’s point.

I think W was also making some kind of distinguishing remark about raising a counter possibility and the *feeling* of being doubtful and being doubtful itself. Think of this example (mine, not W’s but I think captures what he meant). Imagine a drug that is able to induce a *feeling* of doubt even in your most confidently held beliefs (maybe in logic or math). Now just because you feel doubtful doesn’t make it’s doubtful that that belief is false. Consider W’s quote:

“From its seeming to me – or to everyone – to be so, it doesn’t follow that it is so.”

I think W was making the point that true doubt requires justified reasons (and not just coincidentally justified) and not just a feeling of doubt or a mere possibility. That may have been an analytic truth to him as Gettier’s point that it is just an analytic truth (“built in the very meaning”)that knowledge requires more than JTB. Hence someone who claimed to doubt based on some mere possibility and a “doubtful feeling” simply don’t know what to doubt means (though they may in a philosophically irrelevant sense be correct in that usage much as JTB may be correct in some common usage).

To be doubtful you would have to be justified in the doubt in just the right way (just like you would have to be justified in just the right way for a belief to be knowledge). And that would entail you being able to answer a host of questions to which all our common sense beliefs may be connected in some way to that belief. See W’s quote:

“For this demands answers to the questions “How did he overcome the force of gravity?” “How could he live without an atmosphere?” and a thousand others which could not be answered.”

The more certain and “common sense” the belief, the more questions you’d have to answer which are connected to it. Compare this view with Quine’s web of beliefs and I think there’s quite a similarity. With Quine’s web, the closer it is to the center of the web, the more it will disturb the outer edges of that web and more of the whole web will have to be replaced by a more justified system or web of coherent beliefs.

W also notes that normal doubt requires some standard of weight to measure certitude or confidence. We doubt some belief X by using a stronger standard Y. Y provides the standards to put X into question. Even if X ultimately ends up being correct, if we had a stronger standard in a “common sense” Y to justifiably put X into doubt, X would only end up being correct *by coincidence* much like someone who says in his dream “it is raining” may be only coincidentally correct about the status of the non dream world.

Someone who doubted Y without good reason to by holding fast to some contradictory belief X would not be in fact correct to doubt Y in favor of X (compare with the Matrix where we are told that we don’t live in a real world but a dream world where evil robots are controlling our dream environment). He would not have an epistemic right to doubt Y because he could not provide a stronger standard to do so (which would entail coherently and justifiably answering a host of questions related to common sense Y).

I am now convinced that raising mere possibilities cannot justify loss in certainty in some belief as W claimed for much of the same reasons he argued. Doing so would be more akin to artificially inducing a feeling of doubt rather than real doubting. Lowering of confidence in our common sense beliefs (or any belief) has to occur in just the right way much as justification has to occur in just the right way for knowledge. This would still allow for the normative claim that it is still good practice to question all our beliefs but just that when that is done without good justification, it is not real doubt.
