“Reality is defined by the Principle of Sufficient Reason. Anyone who denies this is ipso facto an irrationalist. Whatever they say is necessarily irrational, hence can be immediately discounted. The very act of trying to provide reasons why the Principle of Sufficient Reason is wrong is irrational because, in trying to find reasons, you have already acknowledged the supremacy of the PSR. You cannot use reasons to attack reason while denying the worth of reason. Yet it’s astounding how many people try.”
