Quote by Brouwer, Luitzen Egbertus Jan
"The structure of mathematics is the structure of possible thought."
"The structure of mathematics is the structure of possible thought."
"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."
