Empirical Has Roots in Latin and Greek
Whenempirical first appeared as an adjective in English, it meant simply “in the manner of an empiric.” In the ancient world, empirics were members of a sect of doctors who practiced medicine using treatments observed to be clinically effective, rather than treatments based on theoretical principles. This sounds all fine and good to a modern reader, but empirics were in direct opposition to Galen, the 2nd century Greek physician whose theories and practices (including the theory ofbodily humors) dominated medicine in Europe from the Middle Ages until the mid-17th century. As the underdogs in this rivalry, empirics took some reputational hits, evidenced by the use ofempiric to refer to someone who disregards or deviates from the rules of science or accepted practice; to be called an empiric was sometimes like being called a quack or charlatan.Empirical can still be used critically to describe ideas and practices that rely on experience or observation alone and without due regard for system or theory. But, perhaps in a bit of a case of “the Empirics strike back,”empirical more often keeps its narrower sense, and is used positively to describe evidence and information grounded in observation and experience, or capable of being verified or disproved by observation or experiment.
