“With me, everything turns into mathematics.”

“If we leave that general descriptive talk where everything which looks like a poem can be called a poem and turn instead to normative talk, we will of course not recognize as a poem everything that looks like a poem. A real poem has to be a successful poem, a successful speech act. In approximately the same way that only a mathematical proof which really proves something can be called a mathematical proof. It is not enough that it looks like a proof. The proof has to prove. For the poem it is not enough to look like a poem. It has to achieve something.”

“Mathematics catalogues everything that is not self-contradictory; within that vast inventory, physics is an island of structures rich enough to contain their own beholders.”

“Just as King Midas turned everything to gold, Stalin turned everything to mediocrity.”

“The danger in happiness - "Now everything is turning out right for me; from now on I'll love every turn of fate - Who wants to be my fate?”

“A new field of science was emerging: mathematical cognition, or the scientific inquiry into how the human brain gives rise to mathematics... the transition from mathematics to neuropsychology.”
