Again, all Knowledge is thought to be capable of being taught,

and what comes within its range capable of being learned. And all

teaching is based upon previous knowledge; (a statement you will

find in the Analytics also,)[11] for there are two ways of

teaching, by Syllogism and by Induction. In fact. Induction is

the source of universal propositions, and Syllogism reasons from

these universals.[12] Syllogism then may reason from principles

which cannot be themselves proved Syllogistically: and therefore

must by Induction.

So Knowledge is "a state or mental faculty apt to demonstrate

syllogistically," &c. as in the Analytics:[13] because a man,

strictly and properly speaking, knows, when he establishes his

conclusion in a certain way, and the principles are known to him:

for if they are not better known to him than the conclusion, such

knowledge as he has will be merely accidental.

Let thus much be accepted as a definition of Knowledge.
