science: c.1300, "knowledge (of something) acquired by study," also "a particular branch of knowledge," from O.Fr. science, from L. scientia "knowledge," from sciens (gen. scientis), prp. of scire "to know," probably originally "to separate one thing from another, to distinguish," related to scindere "to cut, divide," from PIE base *skei- (cf. Gk. skhizein "to split, rend, cleave," Goth. skaidan, O.E. sceadan "to divide, separate;" see shed (v.)). Modern sense of "non-arts studies" is attested from 1678. The distinction is commonly understood as between theoretical truth (Gk. episteme) and methods for effecting practical results (tekhne), but science sometimes is used for practical applications and art for applications of skill. Main modern (restricted) sense of "body of regular or methodical observations or propositions ... concerning any subject or speculation" is attested from 1725; in 17c.-18c. this concept commonly was called philosophy.

Politicks is not a science so properly as a business. It cannot have fixed principles, from which a wise man would never swerve, unless the inconstancy of men's view of interest and the capriciousness of the tempers could be fixed." [Fisher Ames (1758–1808)]
