  Reinach's insistence that the objects of a priori knowledge can be considered apart from any realization in the world led to Husserl's later accusation that Reinach embraced a Platonism that “distorted the true picture of phenomenology” (Spiegelberg, p. 192). Yet Reinach explicitly rejected any notion of essences of the sort that would generate any form of third man argument. In his article, “The Supreme Rules of Rational Inference According to Kant” (1911a), he observes that judgments such as “the triangle has three sides” or “the lion has a tail” have often been said to refer to general concepts such as “triangle” or “lion.” But this leads not only to odd ideas (e.g., that a concept has a tail) but also, as Berkeley noted, to impossible ideas (such as a triangle that is at once right-angled, equilateral, and obtuse). Reinach notes that the ontological mistake lies in assuming that essences are substances or really existing particulars; the logical mistake is assuming that judgments about “the triangle” or “the lion” refer to concepts at all. Rather, the judgment that “the triangle has three sides” is more precisely expressed as having the general form “everything that is a triangle has three sides.” It is this general state of affairs that is the specific object of our a priori knowledge.
