Observation apprises us of what's, but not of what must be. It therefore does not apprise us of logical norms or of relationships of logical dependence. Furthermore, the transformation of sensory information (pictorial) information into propositional (conceptual, non-pictorial) information presupposes knowledge of how to convert information of 1 kind into information of various other kind, and it therefore presupposes knowledge of logical equivalencies. Thus, not absolutely all knowledge is derived from sense-perception, even after allowances are created for the variation between knowledge-like, but not genuinely knowledge-mediating, cognitive constructions, on the main one hand, and genuine knowledge, on the other. A philosophical justification is provided for Freud's serious insights, in Section VII of the Interpretation of Dreams, regarding the restrictions of iconic ideation. Wittgenstein's so-called "Picture-Theory" of vocabulary is examined.
