View submission: The Principle of Sufficient Reason is Self-Evident and its Criticisms are Self-Defeating (a case for the PSR being the fourth law of logic)

Summary: The Principle of Sufficient Reason (PSR), which posits that all contingent facts must have sufficient reasons for their existence, is self-evident and fundamental to our understanding of reality (whether or not we admit we accept it). Those who reject the PSR could only do so by accepting the PSR, as any reason-based argument against it would implicitly rely on the need for sufficient reasons. The PSR serves as a basic assumption in science's search for fundamental explanations, and unexplained events should be attributed to the incompleteness of our model, rather than the incompleteness of reality. The text also addresses criticisms of the PSR, particularly concerning quantum indeterminacy, its necessitarian implications, and its demand for infinite causes. The author is happy to answer any questions.

Why can't I simply reject it without giving a reason based argument, or any argument at all?

If I do decide to offer an argument against it - say because an interlocutor wants convincing - doesn't this merely show that I recognize the possibility of reasons, not their necessity? If reasons exist for this one truth it does not follow that reasons exist for other truths - not unless we can be sure there is nothing at all special about our chosen case, and it seems clear that this condition is not met here.

The Principle of Sufficient Reason (PSR), which posits that all **contingent** facts must have sufficient reasons for their existence

As opposed to what other kinds of facts?
