The goal of the article is to describe and critically asses Brentano's and Husserl's theories of abstraction and their ensuing theories of generality. At the beginning I describe Brentano's Conceptualism with regard to some of its historical sources, especially with regard to Aristotelism and the school of Port-Royal.
I then approach Husserl's critique of Nominalism from his Logical Investigations and his theory if general intuition. I try to put the theory of general intuition into the wider context of Husserl's theory of generality in Logical Investigations in order to show a fundamental problem and a certain unclarity of this position.
I then go back to Brentano to show, yet again in relation to Antoin Arnaulds theory, that Brentano's conceptualism is not tenable.
