 present with that, so that there will be some principles that a thing is, but others that it is not. Still when it is required to demonstrate, that which is first predicated of B must be assumed; let this be C, and let A, in like manner, (be predicated) of this; by always proceeding thus, there is never a proposition externally, nor is that which is present with A assumed in the demonstration, but the middle is always condensed till they become indivisible and one. They are one indeed when the immediate is produced, and one proposition simply, an immediate one, and as in other things the principle is simple, but this is not the same every where, but in weight it is a minor, in melody a demi-semi-quaver, and something else in another thing, thus in syllogism, "the one" is an immediate proposition, but in demonstration and science it is intuition. In syllogisms then, which demonstrate the being inherent, nothing falls beyond (the middle), but in negatives here, nothing falls external of that which ought to be inherent, as if A is not present with B through C. For if C is present with every B, but A with no C, and if, again, it should be requisite to show that A is with no C, we must assume the medium of A and C, and thus we must always proceed. If
