Plants, again, inasmuch as they are without locomotion, present no great variety in their heterogeneous pacts. For, when the functions are but few, few also are the organs required to effect them. ... Animals, however, that not only live but perceive, present a great multiformity of pacts, and this diversity is greater in some animals than in others, being most varied in those to whose share has fallen not mere life but life of high degree. Now such an animal is man.

The saying of Protagoras is like the views we have mentioned; he said that man is the measure of all things, meaning simply that that which seems to each man assuredly is. If this is so, it follows that the same thing both is and is not, and is bad and good, and that the contents of all other opposite statements are true, because often a particular thing appears beautiful to some and ugly to others, and that which appears to each man is the measure.

Courage is the mother of all virtues because without it, you cannot consistently perform the others.

Every effort therefore must be made to perpetuate prosperity. And, since that is to the advantage of the rich as well as the poor, all that accrues from the revenues should be collected into a single fund and distributed in block grants to those in need, if possible in lump sums large enough for the acquisition of a small piece of land, but if not, enough to start a business, or work in agriculture. And if that cannot be done for all, the distribution might be by tribes or some other division each in turn.

What has soul in it differs from what has not, in that the former displays life. Now this word has more than one sense, and provided any one alone of these is found in a thing we say that thing is living. Living, that is, may mean thinking or perception or local movement and rest, or movement in the sense of nutrition, decay and growth. Hence we think of plants also as living, for they are observed to possess in themselves an originative power through which they increase or decrease in all spatial directions.

When we look at the matter from another point of view, great caution would seem to be required. For the habit of lightly changing the laws is an evil, and, when the advantage is small, some errors both of lawgivers and rulers had better be left; the citizen will not gain so much by making the change as he will lose by the habit of disobedience.

To Thales the primary question was not what do we know, but how do we know it.
-
Virtue also depends on ourselves. And so also does vice. For where we are free to act we are also free to refrain from acting, and where we are able to say No we are also able to say Yes; if therefore we are responsible for doing a thing when to do it right, we are also responsible for not doing it when not to do it is wrong, and if we are responsible for rightly not doing a thing, we are also responsible for wrongly doing it.
-
It is just that we should be grateful, not only to those with whose views we may agree, but also to those who have expressed more superficial views; for these also contributed something, by developing before us the powers of thought.
-
We praise a man who feels angry on the right grounds and against the right persons and also in the right manner at the right moment and for the right length of time.

The only way to achieve true success is to express yourself completely in service to society.

Irrational passions would seem to be as much a part of human nature as is reason.
-
In general, what is written must be easy to read and easy to speak; which is the same.
-
But it is not at all certain that this superiority of the many over the sound few is possible in the case of every people and every large number. There are some whom it would be impossible: otherwise the theory would apply to wild animals- and yet some men are hardly any better than wild animals.

In the many forms of government which have sprung up there has always been an acknowledgement of justice and proportionate equality, although mankind fail in attaining them, as indeed I have already explained. Democracy, for example, arises out of the notion that those who are equal in any respect are equal in all respects; because men are equally free, they claim to be absolutely equal.

The shape of the heaven is of necessity spherical; for that is the shape most appropriate to its substance and also by nature primary.
-
For as the eyes of bats are to the blaze of day, so is the reason in our soul to the things which are by nature most evident of all.
-
I call that law universal, which is conformable merely to dictates of nature; for there does exist naturally an universal sense of right and wrong, which, in a certain degree, all intuitively divine, even should no intercourse with each other, nor any compact have existed.

... a science must deal with a subject and its properties.

The soul of animals is characterized by two faculties, the faculty of discrimination which is the work of thought and sense, and the faculty of originating local movement.
-
He who is by nature not his own but another's man is by nature a slave.
-
Thus it is thought that justice is equality; and so it is, but not for all persons, only for those that are equal. Inequality also is thought to be just; and so it is, but not for all, only for the unequal. We make bad mistakes if we neglect this for whom when we are deciding what is just. The reason is that we are making judgements about ourselves, and people are generally bad judges where their own interests are involved.

He then alone will strictly be called brave who is fearless of a noble death, and of all such chances as come upon us with sudden death in their train.

But since there is but one aim for the entire state, it follows that education must be one and the same for all, and that the responsibility for it must be a public one, not the private affair which it now is, each man looking after his own children and teaching them privately whatever private curriculum he thinks they ought to study.
