Brouwer, Luitzen
Luitzen Brouwer was a Dutch mathematician and philosopher best known for founding intuitionism, a philosophy of mathematics emphasizing that mathematical truths are mental constructions rather than external realities. His work challenged classical views by asserting that the infinite and certain mathematical concepts are grounded in human intuition. Brouwer's ideas influenced the foundations of mathematics and logic, encouraging a more constructive approach that requires proof of existence through explicit methods. His contributions helped shape modern discussions on the nature of mathematical knowledge and the relationship between mathematics, logic, and philosophy.
