also,)134 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.135 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:136 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.
Chapter IV.
Matter which may exist otherwise than it actually does in any given case (commonly called Contingent) is of two kinds, that which is the object of Making, and that which is the object of Doing; now Making and Doing are two different things (as we show in the exoteric treatise), and so that state of mind, conjoined with Reason, which is apt to Do, is distinct from that also conjoined with Reason, which is apt to Make: and for this reason they are not included one by the other, that is, Doing is not Making, nor Making Doing.137 Now138 as Architecture is an Art, and is the same as “a certain state of mind, conjoined with Reason, which is apt to Make,” and as there is no Art which is not such a state, nor any such state which is not an Art, Art, in its strict and proper sense, must be “a state of mind, conjoined with true Reason, apt to Make.”
Now all Art has to do with production, and contrivance, and seeing how any of those things may be produced which may either be or not be, and the origination of which rests with the maker and not with the thing made.
