Politicks is the science of good sense, applied to public affairs, and, as those are forever changing, what is wisdom to-day would be folly and perhaps, ruin to-morrow. 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), "British Alliance," in the Boston Repertory, November 1806]
The sense of "political actions or practice" is from 1640s. Meaning "political allegiances or opinions of a person or party" is from 1769.
