Calculus went for over 100 years without a formal definition of either
function or derivative, talking about infinitesimal changes without a
formal definition of infinitesimal.  Worse, at some point in a proof it
would be a mistake to discard infinitesimals as "essentially zero," yet
you always did at the end of the proof.  There were no real rules as to
when you should and when you shouldn't.

Formalization often happens only after a field is well understood and
used, usually not before.
