Book 1: The End.
Chapter 4: Men agree that the good is happiness, but differ as to what this is.
Since—to resume—all knowledge and all purpose aims at some good, what is this which we say is the aim of Politics; or, in other words, what is the highest of all realizable goods?
As to its name, I suppose nearly all men are agreed; for the masses and the men of culture alike declare that it is happiness, and hold that to “live well” or to “do well” is the same as to be “happy.”
But they differ as to what this happiness is, and the masses do not give the same account of it as the philosophers.
The former take it to be something palpable and plain, as pleasure or wealth or fame; one man holds it to be this, and another that, and often the same man is of different minds at different times,—after sickness it is health, and in poverty it is wealth; while when they are impressed with the consciousness of their ignorance, they admire most those who say grand things that are above their comprehension.
Some philosophers, on the other hand, have thought that, beside these several good things, there is an “absolute” good which is the cause of their goodness.
As it would hardly be worth while to review all the opinions that have been held, we will confine ourselves to those which are most popular, or which seem to have some foundation in reason.
But we must not omit to notice the distinction that is drawn between the method of proceeding from your starting-points or principles, and the method of working up to them. Plato used with fitness to raise this question, and to ask whether the right way is from or to your starting-points, as in the race-course you may run from the judges to the boundary, or vice versâ.
Well, we must start from what is known.
But “what is known” may mean two things: “what is known to us,” which is one thing, or “what is known” simply, which is another.
I think it is safe to say that we must start from what is known to us.
And on this account nothing but a good moral training can qualify a man to study what is noble and just—in a word, to study questions of Politics. For the undemonstrated fact is here the starting-point, and if this undemonstrated fact be sufficiently evident to a man, he will not require a “reason why.” Now the man who has had a good moral training either has already arrived at starting-points or principles of action, or will easily accept them when pointed out. But he who neither has them nor will accept them may hear what Hesiod says*—
“The best is he who of himself doth know;
Good too is he who listens to the wise;
But he who neither knows himself nor heeds
The words of others, is a useless man.”
