Penelope Fitzgerald offers a "psychological" theory of this, while Alexander Pruss offers a "reassessment" of this concept.  In one work about this subject, its author digresses to call Hegel a charlatan and claim that Hegelian "savants" have led German philosophy to be laughed at as if it were a prostitute. That work also discusses "the divine Plato," argues against Kant's theory of causality and discusses intuitive, perceptive, and complete empirical representations.  The other major writer about this concept used it to account for "truths of fact" as opposed to "truths of reason," a construction adopted by Christian Wolff but rejected by Kant and the author of the work described earlier, Schopenhauer. Advocated in Section 33 of Monadology, FTP, identify this concept championed by Leibniz, mocked by Voltaire and whose "Fourfold Root" was investigated by Schopenhauer, a claim that "nothing is without a reason for its being."
