 The concept of a brute fact is closely related to the Principle of Sufficient Reason (see the entry on the  principle of sufficient reason).  The PSR comes in various versions. For each sense of “brute”, the claim that there are no brute facts is (logically equivalent to) a version of the PSR. Thus if we appeal to the distinction between epistemically brute and metaphysically brute facts, then some of these versions are epistemic (e.g. “Every fact has a deductive-nomological explanation”) and others metaphysical (e.g. “Every fact is grounded”).
