The Three Types of Science

Too Long; Didn't Read

1. Science may be divided into three sorts. All that can fall within the compass of human understanding, being either, FIRST, the nature of things, as they are in themselves, their relations, and their manner of operation: or, SECONDLY, that which man himself ought to do, as a rational and voluntary agent, for the attainment of any end, especially happiness: or, THIRDLY, the ways and means whereby the knowledge of both the one and the other of these is attained and communicated; I think science may be divided properly into these three sorts:— 2. First, Physica. FIRST, The knowledge of things, as they are in their own proper beings, then constitution, properties, and operations; whereby I mean not only matter and body, but spirits also, which have their proper natures, constitutions, and operations, as well as bodies. This, in a little more enlarged sense of the word, I call [word in Greek: physika], or NATURAL PHILOSOPHY. The end of this is bare speculative truth: and whatsoever can afford the mind of man any such, falls under this branch, whether it be God himself, angels, spirits, bodies; or any of their affections, as number, and figure, &c.
