All propositions are composed of concepts. All concepts are linguistically mediated. All awareness is linguistically mediated Dr. Chrucky finds the conclusion of the argument objectionable and something he would like to protect Sellars from having to embrace. His strategy is first to admit that the critics are not unfair in attributing this argument to Sellars but then to go on to show that a close and sympathetic reading of Sellars allows one to divide the argument into two related arguments, whose conclusions are much less shocking and unacceptable. Both kinds of awareness are propositional and hence the original claim, stated in premise 1., survives.
All conceptual awareness is propositional.
All propositions are composed of concepts. All concepts are linguistically mediated. All conceptual awareness is linguistically mediated. All rs-awareness is propositional. No rs-concepts are linguistically mediated.
