The Right Stuff

I consider Kant’s theory of matter, examine his distinction between “formal” and “material” purposiveness, review the related secondary literature, and interpret the role of the stuff of which organs consist in his conception of the special characteristics of organisms. As organisms ingest or absorb compounds, they induce chemical changes among those materials to grow and repair organs. Those organs have their functions with respect to each other in part on account of the materials of which they are composed. A Kantian biological law, I argue, is a coordinated system of lower-order chemical and mechanical regularities that an organism instantiates in the relations that its organs have to each other. I interpret Kant’s contention that organisms resist cognition as claiming that a “discursive understanding” can have no conception of why a particular biological law instantiates whichever lower-order mechanical and chemical regularities it does.
