Cogito synonyms

The axiom of Cartesianism is, therefore, the Cogito ergo sum.

The name is often wrongly spelt Codgers and Coggers; the "o" is really long, the accepted derivation being from Descartes' Cogito, ergo sum, and thus meaning "The society of thinkers."

Descartes, the founder of psychological idealism, having proceeded from the conscious fact, cogito ergo sum, to the non sequitur that I am a soul, and all a soul can perceive is its ideas, nevertheless went on to the further illogical conclusion that from these mental ideas I can (by the grace of God) infer things which are extended substances or bodies, as well as thinking substances or souls.

In this respect Descartes' dictum - cogito ergo sum - may be said to have struck the keynote of modern philosophy, and all subsequent speculation to have been merely a prolonged commentary upon it.
