I think therefore I am - René Descartes

The t-shirt expression “I Do Not Think Therefore I Do Not Am” is a humorous and ironic play on the philosophical statement “Cogito, ergo sum” by René Descartes, which asserts that the act of thinking proves one’s existence. The t-shirt expression suggests the opposite, that the lack of thinking negates one’s existence. It may also be seen as a critique of Descartes’ idea of self and suggests that identity and existence are more complex than mere thinking.
