I have a passion for proving. In my view, proving is the essence of
mathematics. As soon as we ask "why?" we start proving. Proving is
cultivated reasoning. Mathematics cannot be defined by the objects studied but
only by its method, which is proving. Formal proving, the basis of
computersupported proving, will drastically change the way we do mathematics.
Computing is a special case of proving, and proving is a special case of
computing. Actually, computing and proving are two of the three main aspects of
formal mathematical activity. The third aspect is solving. Proving, solving, and
computing naturally correspond to the way free variables in formulae are
considered: They can be universally quantified, existentially quantified, or
left free for substitution.
