When empirical first appeared as an adjective in English, it meant simply "in the manner of an empiric." An empiric was a member of an ancient sect of doctors who practiced medicine based exclusively on experience, as contrasted with those who relied on theory or philosophy. The name empiric derives from Latin empiricus, itself from Greek empeirikos ("experienced"). It ultimately traces back to the verb peiran, meaning "to try, attempt, or experiment."
