of the several subjects of knowledge.
There are of knowledge two kinds; whereof one is knowledge of fact: the other knowledge of the consequence of one affirmation to another. The former is nothing else, but sense and memory, and is absolute knowledge; as when we see a fact doing, or remember it done: and this is the knowledge required in a witness. The latter is called science; and is conditional; as when we know, that, if the figure shown be a circle, then any straight line through the centre shall divide it into two equal parts. And this is the knowledge required in a philosopher; that is to say, of him that pretends to reasoning.
The register of knowledge of fact is called history. Whereof there be two sorts: one called natural history; which is the history of such facts, or effects of nature, as have no dependence on man’s will; such as are the histories of metals, plants, animals, regions, and the like. The other, is civil history; which is the history of the voluntary actions of men in commonwealths.
The registers of science, are such books as contain the demonstrations of consequences of one affirmation, to another; and are commonly called books of philosophy; whereof the sorts are many, according to the diversity of the matter; and may be divided in such manner as I have divided them in the following table.
