Definitions, examples, theorems, proofs -- they all seem so
inevitable. But how did they come to be that way? What is
the role of counterexamples? Why are some definitions so
peculiar? What good are proofs?
In this brilliant and deep -- yet easy to read -- book,
Lakatos shows how mathematicians explore concepts; how their
ideas can develop over time; and how misleading the "textbook"
presentation of math really is.
Fascinating for anyone who has seen mathematical proofs
(even high-school Euclidean geometry) and essential for
anyone studying mathematics at any level.
