products of contemplation, intellectual objects in
the mind, and of and for the mind exclusively.
--Coleridge.
[1913 Webster]
By the theorems,
Which your polite and terser gallants practice,
I re-refine the court, and civilize
Their barbarous natures. --Massinger.

Note: A theorem is something to be proved, and is thus
distinguished from a problem, which is something to be
solved. In analysis, the term is sometimes applied to a
rule, especially a rule or statement of relations
expressed in a formula or by symbols; as, the binomial
theorem; Taylor's theorem. See the Note under
Proposition, n., 5.
[1913 Webster]
Binomial theorem. (Math.) See under Binomial.
Negative theorem, a theorem which expresses the

a particular quantity.
Theorem of Pappus. (Math.) See Centrobaric method, under
Centrobaric.
Universal theorem (Math.), a theorem which extends to any
quantity without restriction.
