Additional quotes by René Descartes
Γνωρίζω ότι υπάρχω, και ρωτάω ποιος είμαι εγώ, το εγώ που γνωρίζω. Είναι παραπάνω από βέβαιο ότι γνώση που έχω γι' αυτό το εγώ, με την ακριβή του έννοια, δεν εξαρτάται από αυτό που δεν γνωρίζω ακόμα αν υπάρχει.
Cogito ergo sum
I doubt, therefore I think, therefore I am.
