Question

Quizplus · Accepted Answer

Descartes argues that while one can doubt the existence of the physical body and its properties (such as self-movement, extension, and sight), one cannot doubt the existence of the self as a thinking thing. This is encapsulated in his famous dictum "Cogito, ergo sum" ("I think, therefore I am"). Therefore, the correct answer is that it is impossible to doubt none of the options given, as they all pertain to physical properties or abilities, which Descartes believes can be doubted.
