Now ... the basic principle of modern mathematics is to achieve a complete fusion [of] 'geometric' and 'analytic' ideas.
Jean DieudonneOn foundations we believe in the reality of mathematics, but of course, when philosophers attack us with their paradoxes, we rush to hide behind formalism and say 'mathematics is just a combination of meaningless symbols,'... Finally we are left in peace to go back to our mathematics and do it as we have always done, with the feeling each mathematician has that he is working with something real. The sensation is probably an illusion, but it is very convenient.
Jean DieudonneWe have not begun to understand the relationship between combinatorics and conceptual mathematics.
Jean DieudonneThe life of a mathematician is dominated by an insatiable curiosity, a desire bordering on passion to solve the problems he is studying.
