Quote by Brouwer, Luitzen Egbertus Jan
"Logic is not the foundation of mathematics; intuition is."
"Logic is not the foundation of mathematics; intuition is."
"Mathematics is not about numbers, equations, computations, or algorithms: it is about understanding."
"The intuitionist does not accept the axiom of the excluded middle."
"Creating mathematics is like creating poetry or music."
"The act of intuitively creating a mathematical system requires freedom of thought."
