Bayesian email filters take advantage of Bayes' theorem. Bayes' theorem is used several times in the context of spam:
- a first time, to compute the probability that the message is spam, knowing that a given word appears in this message;
- a second time, to compute the probability that the message is spam, taking into consideration all of its words (or a relevant subset of them);
- sometimes a third time, to deal with rare words.

Famous quotes containing the words mathematical and/or foundation:
“As we speak of poetical beauty, so ought we to speak of mathematical beauty and medical beauty. But we do not do so; and that reason is that we know well what is the object of mathematics, and that it consists in proofs, and what is the object of medicine, and that it consists in healing. But we do not know in what grace consists, which is the object of poetry.”
—Blaise Pascal (1623–1662)
“The foundation of empire is art & science. Remove them or degrade them, & the empire is no more. Empire follows art & not vice versa as Englishmen suppose.”
—William Blake (1757–1827)
