The chosen objection is the comprehensive physical knowledge with no knowledge of physical facts. Jackson’s first premise asserts that if Mary has all the physical truths in regard to human color visualization then she understands the wholesome truth (Nida-Rümelin 1). It can be argued that Mary lacks adequate knowledge in regard to the functional truths in regard to human vision as he lacks the idea of what it entails for an object that is red, yellow, and black and so on. According to metaphysical physicalism, all the physical things can be expressed or acquired in the languages of physical science (Nida-Rümelin 1). The argument should have incorporated the premise that all the physical facts can be established conversationally.
