Hah. Funny reference. Anyways, this is the new Atheous thread. I’ll be providing a new argument for atheism complete with new definitions and sub-arguments. I hope this will foster as good a discussion as the last one did.
Atheous 2
Main Argument:
Definition:
D1: An instance of suffering, E, is inscrutable for S if and only if (i) S believes E has obtained, and (ii) after attempting to discern whether E is morally justified, S fails to know of any moral justification for E. (Note, this is compatible with a theist’s belief that God is morally justified in permitting E, it’d just mean the theist doesn’t know what that justification is).
Argument:
Before motivating my premises, I want to elaborate on the notion of probability premise (1) refers to. Probability, as I’m using it, refers to the amount or degree of confidence a cognizer has that a proposition bares a particular truth-value.
We numerically represent these degrees of confidence on a scale of 1.0-0.0. 1.0 represents our highest confidence, 0.5 represents our doxastic indifference and 0.0 represents our least amount. The idea of numerically representing our subjective states seems quite common. e.g., ‘How much pain do you feel on a scale of 1-10?’.
I understand (1) to mean that if inscrutable suffering occurs, our degree of confidence in atheism should be higher than doxastic indifference i.e., we should believe atheism is true. This leads me to my motivation of (1).
Premise (1):
I’ll use Bayes’ theorem for this premise and, for the sake of space, will have to assume the reader is able to follow.
I believe (1) will be accepted as true by most people, atheists and theists alike. I say most for reasons I’ll shortly get into.
Let T = Theism, ~T = the denial of T or Atheism, I = Inscrutable Suffering and K = our background knowledge.
My first goal in motivating (1) is to show that P(I|~T&K) is extremely high. My second goal is to show that P(I|T&K) is very low. The result will be that the only way P(T|I&K) > P(~T|I&K) is if P(T|K) is exceedingly high.
This is why I said most people will accept (1). There will of course be some theists who have such an impressive prior for theism that no argument could sway them. So, I wouldn’t consider their rejection of this premise particularly interesting anyways.
Motivation of (1) p1:
Definition:
D2: An instance of suffering, E, is morally gratuitous if there exists no moral good in virtue of which E is morally justified. In our Bayesian notation, let M represent (4)'s consequent.
Sub-Argument:
6’. P(I|~T&K)
A logically valid argument is one which if its premises are true, its conclusion must be true. This is why the probability of the conclusion of any sound deductive argument is 1.0. So, if (4)-(5) are true, then P(I|~T&K)=1.0.
My goal therefore is to first show that (4)-(5) are true, and then to drive a chasm between (6’)'s probability and P(I|T&K).

Argument:
- If inscrutable suffering occurs, atheism is probably true.
- Inscrutable suffering occurs.
- Therefore, atheism is probably true.

Sub-Argument:
- If atheism is true, then morally gratuitous suffering occurs.
- If morally gratuitous suffering occurs, then inscrutable suffering occurs.
- Therefore, if atheism is true, then inscrutable suffering occurs.
