Critiques of Aristotle’s concept of privation, or the absence of a form, often center on whether it’s a legitimate principle of being, its role in causation, and its potential metaphysical or conceptual inconsistencies within his hylomorphic theory. Critics question if privation is truly a “third principle” alongside matter and form, a mere negative mode of being, or if it’s a contradiction to attribute causal power to non-being. Some analyses suggest it functions as a “qualified form” to account for changing substances but then face challenges in defining its exact ontological status and its relationship to fundamental substance.
