Sextus Empirĭcus
A physician who was a contemporary of Galen, and lived in the first half of the third
century of the Christian era. Two of his works are extant—
Πυρρώνιαι Ὑποπτυπώσεις, dealing with the skeptical learning of
Pyrrho (q.v.), in three books; and
Πρὸς τοὺς Μαθηματικοὺς Ἀντιρρητικοί, in eleven books, against all positive
philosophy. The first six books strive to show the falsity of the sciences of grammar,
rhetoric, geometry, arithmetic, astrology, and music; the last five attack logic, physics, and
ethics. Edited by Fabricius
(Leipzig, 1718). See

(1858) and Pappenheim
