## A quotation by Raymond Wilder

There is nothing mysterious, as some have tried to maintain, about the applicability of mathematics. What we get by abstraction from something can be returned.

*Introduction to the Foundations of Mathematics.*

Mathematics was born and nurtured in a cultural environment. Without the perspective which the cultural background affords, a proper appreciation of the content and state of present-day mathematics is hardly possible.

*The American Mathematical Monthly*, March 1994.
