Is There a Law of Non Contrast?

A law of non contradiction reveals that we have a two category reality. We have a reality in which there is some portion of reality, namely the totality, that lacks an outside explanation. But this is already weird, because the things we ordinarily experience have outside explanations beyond themselves. So i don't think the infinite regret has really even address is the problem. The infinite regrets really just does nothing to address this more basic problem of how there can be anything ifeverything is purely contingent in its nature.
