one property and not many, in this respect property of moisture would be well stated.
Chapter 3
In the next place, the subverter (ought to consider) if he (the proposer) has used that, the property of which he assigns, or some of its (subjects), for the property will not be well laid down. For the property is assigned, for the sake of learning; the same thing therefore is similarly unknown with itself, but what is the subject of a certain thing is posterior to it, and therefore is not more known. Hence, through these, greater instruction in any thing does not happen, e.g. since he who states the property of animal, to be a substance, a species of which is man, uses some one of the subjects of this (animal), the property would not be well stated. But the confirmer (must observe) if he uses neither it, nor any of its subjects, for in this respect, property will be well stated; thus, since he who lays down the property of animal, to be composed of soul and body neither uses it, nor any of its subjects, the property of animal, with regard to this, would be well assigned.
In the same manner, also, consideration must be paid as to the other things which do not, or which do render, a thing more known, subverting, indeed, if what is opposite is used, or in short, what is simultaneous in nature, or any thing posterior, for the property will not be well stated. What is opposite is indeed simultaneous in nature, but what is simultaneous in nature and what is posterior, do not render a thing more known. For instance, since he who states the property of good, to be that which is especially opposed to evil, uses the opposite of good, the property of good would not be well assigned. On the other hand, we confirm it if nothing opposite is used, nor, in short, what is simultaneous in nature, nor what is posterior, for as to this, the property will be well assigned; e.g. since he who lays down the property of knowledge, to be a notion in the highest degree credible, uses neither an opposite, nor what is simultaneous
