But this foreward to these prolegomena has been already
longer than enough; so that, though there remains something
that must yet be added to it, the Gracious Reader for whose attention
to my screed I am warmly grateful, though I have no further acquaintance with him as yet, is hereby
invited to assist at the formulation of our diagram of thought.

This diagram, in any one state of it, shall map out what thinking
is, in any stage of discussion, actual; and the diagram shall successively
undergo modifications to represent the passage from
premisses to conclusions. Let us scribe,---that is, write or
draw, or partly write and partly draw,---our diagram
upon a certain side of a certain sheet of paper or
pasteboard appropriated to the purpose; and let us call this
side of the sheet the recto. Then, the recto will stand for
the quasi-mind.
