Let’s put it this way: is it self deception to do one’s best to persuade oneself that 0.9999… = 1? That is one of many true but hard to believe mathematical statements. We have many good formal proofs (“infallible” for all practical purposes, if you wish) for that statement. So, would going through those proofs again and again until one’s brain gives up and accepts the statement count as “self deception”? I would say that it is not “self deception”, because it wouldn’t be “deception” if it was done by someone else.…but what sets that apart from self deception?
Or, if you want something “less infallible” - would it be “self deception” to try to persuade oneself that Theory of Relativity or Quantum Mechanics are true? Would you say it is “self deception” to persuade oneself of truth of Darwinian evolution?
Or let’s look at something even more “less infallible”. Is it “self deception” when a judge (or jury, or some other institution) declares that defendant is “not guilty” without anything close to a proof that the defendant is innocent? For example, when the evidence indicates that the defendant is guilty - but that evidence is just not strong enough to go beyond “reasonable doubt”? Would you say it is “self deception” to act as if the defendant is not guilty in such case - even if there are good reasons to think that such way to act is perfectly rational given the evidence?
And Pascal’s Wager is supposed to be like that: as a precondition, the “audience” consists of the ones who have no idea if God exists (“It is all so complicated!” or something like that - if someone can make a decision on different grounds, Pascal’s Wager is irrelevant, just as presumption of innocence is irrelevant if we have definite proof of guilt or innocence). Then that argument shows that in such case it is rational to act as if one had a belief that God exists (and it is also rational to have such a belief). Is it “self deception” to act in the way that seems to be rational given the evidence?
In other words, the Pascal’s Wager is supposed to say: “God is to be presumed to exist, unless it can be demonstrated that He does not exist.”.
