"The structure of mathematics mirrors the structure of the mind that creates it."
"The structure of mathematics mirrors the structure of the mind that creates it."
"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."
