Question

Who said the following? - “Thoughts themselves are symbolic representations”

Answer 1

Rene Descartes told this

Answer 2

This statement is of René Descartes.

René Descartes is frequently credited with being the "Father of Modern Philosophy." This title is legitimized due both to his break with the customary Scholastic-Aristotelian rationality predominant at his opportunity and advancement and promotion of the new, mechanistic sciences. 

His fundamental break with Scholastic logic was twofold. To start with, Descartes felt that the Scholastics' strategy was inclined to question given their dependence on sensation as the source for all knowledge. Second, he needed to supplant their last causal model of logical clarification with the more current, mechanistic model.
