Many of the arguments against religion/faith/creation that I see on this site seem to be implicitly recognizing the Law Of Contradiction. In other words they are trying to show that there is a contradiction inherent in the belief in God or in the bible, and therefore that God does not exist or the bible is not true. I am curious if that is in fact where these arguments stem from, and if so, does everyone accept this Law as a fundamental truth.
I haven't read the whole of this thread, so what I have to say may already have been covered but I wanted to answer your question.
Firstly, I'll need to reframe your question: what is a "law"? what is a "truth"? And how may a truth be "fundamental"?
I don't accept the existence of laws; laws as we see them are abstractions of real properties of the universe at best; and inventions of the human mind at worst.
Truth is real; but only for a specific subset of possible questions which may be answered objectively by reference to reality - something we have no direct access to; and doesn't always answer in ways that fit with our impressions.
A fundemental truth I shall assume, is one somehow primary to other; as such I do not accept any human derived law as such - see above.
None-the-less I do accept the law of non-contradiction. It is empirically derivable from the world around us and does seem to hold given suitable caveats and frame of reference.
