“All things, at least those we know, contain number”
The Life of Pythagoras (1919)
Context: Fragment 2. All things, at least those we know, contain number; for it is evident that nothing whatever can either be thought or known, without number. Number has two distinct kinds: the odd, and the even, and a third, derived from a mingling of the other two kinds, the even-odd. Each of its subspecies is susceptible of many very numerous varieties; which each manifests individually.

The Passionate State Of Mind, and Other Aphorisms (1955)
Context: Our credulity is greatest concerning the things we know least about. And since we know least about ourselves, we are ready to believe all that is said about us. Hence the mysterious power of both flattery and calumny.... It is thus with most of us: we are what other people say we are. We know ourselves chiefly by hearsay.

Context: We hear often of the distress of the negro servants, on the loss of a kind master; and with good reason, for no creature on God's earth is left more utterly unprotected and desolate than the slave in these circumstances.
The child who has lost a father has still the protection of friends, and of the law; he is something, and can do something, — has acknowledged rights and position; the slave has none. The law regards him, in every respect, as devoid of rights as a bale of merchandise. The only possible acknowledgment of any of the longings and wants of a human and immortal creature, which are given to him, comes to him through the sovereign and irresponsible will of his master; and when that master is stricken down, nothing remains.
The number of those men who know how to use wholly irresponsible power humanely and generously is small. Everybody knows this, and the slave knows it best of all; so that he feels that there are ten chances of his finding an abusive and tyrannical master, to one of his finding a considerate and kind one. Therefore is it that the wail over a kind master is loud and long, as well it may be.

Source: The Prince (1513), Ch. 3 (as translated by RM Adams). Variants [these can seem to generalize the circumstances in ways that the translation above does not.]: The Romans, foreseeing troubles, dealt with them at once, and, even to avoid a war, would not let them come to a head, for they knew that war is not to be avoided, but is only put off to the advantage of others.
There is no avoiding war; it can only be postponed to the advantage of others.
Context: The Romans never allowed a trouble spot to remain simply to avoid going to war over it, because they knew that wars don't just go away, they are only postponed to someone else's advantage. Therefore, they made war with Philip and Antiochus in Greece, in order not to have to fight them in Italy... They never went by that saying which you constantly hear from the wiseacres of our day, that time heals all things. They trusted rather their own character and prudence — knowing perfectly well that time contains the seeds of all things, good as well as bad.
