...in this way the structure of the universe- I mean, of the heavens and the earth and the whole world- was arranged by one harmony through the blending of the most opposite principles.
... on principle, it is quite wrong to try founding a theory on observable magnitudes alone. In reality the very opposite happens. It is the theory which decides what we can observe.
It is absolutely impossible for a subject to see or have insight into something while leaving itself out of the picture, so impossible that knowing and being are the most opposite of all spheres.
I've done a lot of independent film, which are short shoots that are usually four to six weeks, max. I enjoy everything. After one particular experience of work, I like to go in the opposite direction and do a short film, or something else.
Therefore it is unnecessary for a prince to have all the good qualities I have enumerated, but it is very necessary to appear to have them. And I shall dare to say this also, that to have them and always to observe them is injurious, and that to appear to have them is useful; to appear merciful, faithful, humane, religious, upright, and to be so, but with a mind so framed that should you require not to be so, you may be able and know how to change to the opposite.
There is nothing very odd about lambs disliking birds of prey, but this is no reason for holding it against large birds of prey that they carry off lambs. And when the lambs whisper among themselves, "These birds of prey are evil, and does this not give us a right to say that whatever is the opposite of a bird of prey must be good," there is nothing intrinsically wrong with such an argument-though the birds of prey will look somewhat quizzically and say, We have nothing against these good lambs; in fact, we love them; nothing tastes better than a tender lamb.
The disposition of noble dogs is to be gentle with people they know and the opposite with those they don't know...How, then, can the dog be anything other than a lover of learning since it defines what's its own and what's alien.
Rhetoric is useful because the true and the just are naturally superior to their opposites, so that, if decisions are improperly made, they must owe their defeat to their own advocates; which is reprehensible. Further, in dealing with certain persons, even if we possessed the most accurate scientific knowledge, we should not find it easy to persuade them by the employment of such knowledge. For scientific discourse is concerned with instruction, but in the case of such persons instruction is impossible.
What connexion can there be, between the place in Lincolnshire, the house in town, the Mercury in powder, and the whereabout of Jo the outlaw with the broom, who had that distant ray of light upon him when he swept the churchyard-step? What connexion can there have been between many people in the innumerable histories of this world, who, from opposite sides of great gulfs, have, nevertheless, been very curiously brought together!
.. we shall not be properly educated ourselves, nor will the guardians whom we are training, until we can recognise the qualities of discipline, courage, generosity, greatness of mind, and others akin to them, as well as their opposites in all their manifestations.
I have argued with him on almost every subject in the world, and we have always been on opposite sides, without affectation or animosity... It is necessary to disagree with him as much as I do, in order to admire him as I do; and I am proud of him as a foe even more than as a friend.
