Abstract

Schlick held that our knowledge is founded upon certain contingent apprehensions which he described as follows: "I grasp their meaning at the same time that I grasp their truth." He cites as an example the apprehension expressed by "Yellow here now." When such apprehensions are expressed in syntactically well-formed sentences, they can be seen to have certain psychological states as their objects - and therefore to be similar in all essential respects to what members of the Brentano school had called "inner perceptions."
