Science—Latin, scientia—can signify an integrated corpus of knowledge as well as a systematic method of study that enables humans to wrest reliable knowledge from the world around us. A slightly more speculative etymology traces “science” to the Greek skhizein, “to split, cleave, or separate” and to the Latin scindere, “to cut, rend, or tear asunder.” As Peter Harrison argues, scientia understood as a body of knowledge, an exterior entity rather than an interior disposition or habit of mind, is of relatively recent vintage. This understanding emerged alongside intentional and sometimes zealous efforts to separate science from not-science.
