Question

Did you know? Descartes' "Cogito, ergo sum" — "I think, therefore I am" (1637) — was his single certainty after doubting everything else away. Even if everything around him were illusion, the fact that he doubts implies something that doubts exists. It is the foundation of modern philosophy.

Descartes' "Cogito, ergo sum" — "I think, therefore I am" (1637) — was his single certainty after doubting everything else away. Even if everything around him were illusion, the fact that he doubts implies something that doubts exists. It is the foundation of modern philosophy.

Descartes' "Cogito, ergo sum" — "ik denk, dus ik ben" (1637) — was zijn enige zekerheid na alle twijfel weg te denken. Zelfs als alles om hem heen illusie zou zijn, het feit dat hij twijfelt impliceert dat er iets is dat twijfelt. Het is het fundament van moderne filosofie.
