That compasses will not make a circle.
It is the draughtsman.
That a round hole will not surround a square handle. That the shadow of a flying bird does not move. That there is a moment when a swiftly-flying arrow is neither moving nor at rest. That a dog is not a hound.
Two things cannot be identical unless even their names are the same.
That a bay horse and a dun cow are three.
Taken separately they are two. Taken together they are one. One and two make three.
That a white dog is black.
If his eyes are black. Part standing for the whole.
That a motherless colt never had a mother.
When it had a mother, it was not an orphan.
