Re: Peirce List https://list.iupui.edu/sympa/arc/peirce-l/2021-06/thrd4.html#00078 ::: Mauro Bertani https://list.iupui.edu/sympa/arc/peirce-l/2021-06/msg00109.html <QUOTE MB:> About Lobe Connective and Node Connective and their consequences, I have a question: You say that genus and species are evaluated by the proposition (a, (b),(c)). The following proposition would no longer be appropriate: a (b, c). And another question about differential calculus: When we talk about A and dA we talk about A and (A) or is it more similar to A and B? </QUOTE> Dear Mauro, The proposition (a, (b),(c)) describes a genus a divided into species b and c. The proposition a (b, c) says a is always true while just one of b or c is true. The first proposition leaves space between the whole universe and the genus a while the second proposition identifies the genus a with the whole universe. The differential proposition dA is one we use to describe a change of state (or a state of change) from A to (A) or the reverse.
