merely to lead up to Thirdness and to the particular
kind and aspect of thirdness which is the sole object
of logical study. I want first to show you what Genuine
Thirdness is and what are its two degenerate forms.
Now we found the genuine and degenerate forms of
secondness by considering the full ideas of First and Second.
Then the genuine Secondness was found to be ReAction, where
First and Second are both true Seconds and the Secondness is something

Let us proceed in the same way with Thirdness. We
have here a First, a Second, and a Third. The first is
