This is quite feasible, for the challenge of simplification is so fascinating that, if we do our job properly, we shall have the greatest fun in the world. -- E. W. Dijkstra, On the nature of computing science.

We now come to the decisive step of mathematical abstraction: we forget about what the symbols stand for. ...[The mathematician] need not be idle; there are many operations which he may carry out with these symbols, without ever having to look at the things they stand for. -- Hermann Weyl, The Mathematical Way of Thinking

Within a computer natural language is unnatural. -- Alan J. Perlis (Epigrams in programming)
