What is the difference between Frege’s and Descartes’ theory of ideas?

What was Descartes theory?

Descartes argued the theory of innate knowledge and that all humans were born with knowledge through the higher power of God. It was this theory of innate knowledge that was later combated by philosopher John Locke (1632–1704), an empiricist. Empiricism holds that all knowledge is acquired through experience.

What were Descartes main ideas?

Scholars agree that Descartes recognizes at least three innate ideas: the idea of God, the idea of (finite) mind, and the idea of (indefinite) body. In the letter to Elisabeth, he includes a fourth: the idea of the union (of mind and body). There is an alternate division of ideas worth noting.

What does Frege mean by thought?

Frege on Thoughts and Representations. To fix the terms, for Frege the term ‘thought’ [Gedanke] is reserved for a sense of a declarative sentence that has as its referent a truth value (Frege, 1918, p. 292). This is to say that ‘thoughts’ (and only ‘thoughts’, thus defined) are what partake of truth and falsity.

What are clear and distinct ideas according to Descartes?

Clear and Distinct Perception

Clear and distinct perceptions are defined by Descartes as those perceptions which are so self-evident that, while they are held in the mind, they cannot logically be doubted.

Where do our ideas come from Descartes vs Locke?

The central distinction between Descartes and Locke is that Descartes holds that the ideas are gained when one is born while Locke trusts that ideas come just through experience. Consequently, Descartes endeavors to find from the fundamental principle the thought of the existence of God.

How does René Descartes explain his idea about self?

Locke provides a stronger point of view than Descartes because the evidence in his philosophy goes so far out of his own understanding.

Why did Locke reject Descartes theory of innate ideas?

They are not innate or intuitive knowledge. They are not a priori or prior to all experience. Thus Locke has rejected Descartes’ doctrine of innate ideas. Locke has further expounded the role of experience even in case of those ideas which are present in all minds in order to disapprove their innateness.
