Peirce's graphs), and I'm painfully aware of that fact:    (02)

And by the way, I have found that teaching introductory
logic in terms of Peirce's existential graphs is a very big
help in getting *both* kinds of students up to speed much
more quickly.    (04)

Many nonmathematicians have bad feelings about algebra

otherwise quite sane.  And the diagrams get them over the
"speed bump" more quickly.    (05)
