- This point is raised by Whitehead and Russell in _Principia Mathematica_.
- The point out that the definitions may be more important than the
- formal manipulations; they indicate what something is and why it
- is important.
-
- Now they were writing primarily for mathematicians. For non-mathematicians,
- I would say that the concepts are the important item, and the translation
- to and from mathematics. Also, I would prefer using characterizations to
- definitions; one can have many characterizations of the same thing, but
- at least in mathematics there can only be one definition.
