Actually, I think I used the wrong word in this caption. The name of the course lesson for this school of fish should be Philosophy, not Logic. The theorem, I think, therefore I am is by a philosopher, not a logician! (I took both subjects, but apparently not enough of either.)

Philosopher Rene Descartes

Some cartoon ideas just resonate with a cartoonist more than others, and this is one of them. We keep working at it with different captions, trying to get it “right”!

Some variations:

I think, therefore I am

Cogito ergo sum

je pense, donc je suis

I fish, therefore I am. (Or, I am, therefore I am a fish.)

Rene Descartes chose to write this theorem in French, rather than Latin, to reach a wider audience in his country than just scholars.

He forgot text slang.

My latest cartoon in PsychCentral is about the lady or the tiger. (If you’ve heard of Descartes, you probably already read the short story.}

ID: #646iu Fish school. Instructor says, “I swim, therefore I am.”

Completely off topic: I am a big fan of Swimfan, the movie. I’m a high schooler.
