.. 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.
Nothing shocks our moral feelings so deeply as cruelty does. We can forgive every other crime, but not cruelty. The reason for this is that it is the very opposite of compassion.
Cosmos is a Greek word for the order of the universe. It is, in a way, the opposite of Chaos. It implies the deep interconnectedness of all things. It conveys awe for the intricate and subtle way in which the universe is put together.
Where there is happiness, there is found pleasure in nonsense. The transformation of experience into its opposite, of the suitable into the unsuitable, the obligatory into the optional (but in such a manner that this process produces no injury and is only imagined in jest), is a pleasure.
But nirvana is a radical transformation of how it feels to be alive: it feels as if everything were myself, or as if everything---including "my" thoughts and actions---were happening of itself. There are still efforts, choices, and decisions, but not the sense that "I make them"; they arise of themselves in relation to circumstances. This is therefore to feel life, not as an encounter between subject and object, but as a polarized field where the contest of opposites has become the play of opposites.
We ought to be able to persuade on opposite sides of a question; as also we ought in the case of arguing by syllogism: not that we should practice both, for it is not right to persuade to what is bad; but in order that the bearing of the case may not escape us, and that when another makes an unfair use of these reasonings, we may be able to solve them.
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.
Education is implication. It is not the things you say which children
respect; when you say things, they very commonly laugh and do the opposite.
It is the things you assume which really sink into them. It is the things
you forget even to teach that they learn.
As a general rule, do not kick the shins of the opposite gentleman under the table, if personally unaquainted with him; your pleasantry is liable to be misunderstood--a circumstance at all times unpleasant.
... 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.
