Descartes classifies his ideas into three types: innate ideas (inborn and a priori knowledge), adventitious ideas (acquired through sensory experience), and factitious ideas (formed by humans based on combinations of innate and adventitious ideas).

Plato and René Descartes believed that innate knowledge can be discovered through logical reasoning. Plato argued that knowledge is recollection of the forms, while Descartes believed in innate ideas that can be accessed through reason and doubt.

Rene Descartes concluded that certain ideas, such as those of God, self, and mathematical truths, were inborn and innate in the mind. He believed that these ideas were not learned but were already present from birth.

No, John Locke rejected Plato's theory of innate ideas. Locke believed that the mind at birth is a blank slate (tabula rasa) and that knowledge comes from experience through the senses. He argued that all knowledge is derived from sensory perception and reflection on our experiences.

No, Descartes did not believe in tabula rasa. He believed that innate ideas existed within the mind prior to experience. Descartes argued that the mind had certain inherent knowledge, such as the concept of God, which did not require sensory input to be known.
