“I think, therefore I am. I think.”
George Carlin
“Cogito cogito ergo cogito sum - I think that I think, therefore I think that I am.”
Ambrose Bierce
“I think, therefor I am”
Rene Descartes
“The most erroneous stories are those we think we know best - and therefore never scrutinize or question.”
Stephen Jay Gould
“I therefore claim to show, not how men think in myths, but how myths operate in men's minds without their being aware of the fact.”
Claude Levi-Strauss
“'I think therefore I am' is the statement of an intellectual who underrates toothaches”
Milan Kundera
“Descartes said: "I think, therefore I am." Helvetius wants to say: "I feel, therefore I want to feel pleasantly." I prefer Hobbes who claims that in order to draw a conclusion which takes us somewhere, we must say, "I feel, I think, I judge; therefore, a part of organized matter like me is capable of feeling, thinking, and judging."”
Denis Diderot
