 Brentano concludes that the distinction between judgement and presentation is intrinsic and irreducible to other distinctions between these mental phenomena. Hillebrand (1891: 26–7) called Brentano’s view therefore an “idiogenetic” theory of judgement—it takes judgement to be a fundamental kind of mental phenomenon—while “allogenetic” theories take judgements to be composed out of other mental phenomena that belong to fundamental kinds.
