his walking now, asserts this with a distinction, the property would be well alleged.
Next, it is subverted if such a property is assigned, which is in no other way evident to be inherent than by sense, since the property will not be well placed; for every thing sensible, when it is external to sense becomes obscure, since it is not apparent whether it is still inherent, because of its only being known by sense. This, indeed, would be true in those things which do not always follow from necessity. For example, since he who asserts the property of the sun to be the most splendid star moved above the earth, uses such (an expression) in the property, to be moved above the earth, which is known by sense, the property of the sun would not be well assigned, for it would be doubtful when the sun sets, whether it is moved above the earth, because of sense then failing us. Property, however, is confirmed if such a kind has been given, as is not evident to sense, or which, being sensible, is manifestly inherent of necessity, for in this respect the property will be well stated. Thus, since he who lays down, as the property of superficies, to be that which is first coloured, uses, indeed, something sensible, viz. to be coloured, but of such a kind as is evidently always inherent, in this respect the property of superficies would be well assigned.
Next, it is subverted if definition is assigned as property, for the property will not be well stated, since it ought not to manifest the very nature of a thing; e.g. since he who says the property of man is to be an animal pedestrian biped, assigns as the property of man that which signifies his very nature, the property of man would not be well assigned. But we confirm it if a property which reciprocates is assigned, yet which does not manifest the very nature of a thing, since in this respect the property would be well assigned; e.g. since he who states the property of man to be an animal naturally mild, assigns a property which reciprocates indeed, yet does not manifest the very nature of man, in this respect the property of man would be well assigned.
