Yes, philosophers argue "hard logic" is a subset of philosophy and the human experience, and its claim to truth is as unstable and fuzzy as the rest of said human experience - to the extent it can be applied to the real world at all. Moreover, the use of "hard logic" brings its own relative cultural perspective that steamrolls others without foundational claim to truth. Appealing to "hard logic" without awareness and acknowledgement of other arguments for claims to truth is thus seen as naive or arguably unethical, especially when imposed into systems that limit other discussions of truth.

That said, there are logical positivist philosophers that believe reality is consistent with a hard logic view of the world, and thus it is foundational. They are a minority these days as far as I know - falling out of favor since... Kant? (I forget my history).

But no, philosophy is not a relic of the past in the sense that it has been surpassed by logic/science/etc - not til those can lay claim to truth better than a bunch of old Athenians. Jury's still out.
