Human beings are not born identical. There are many different temperaments and constitutions; and within each psycho-physical class one can find people at very different stages of spiritual development. Forms of worship and spiritual discipline which may be valuable for one individual maybe useless or even positively harmful for another belonging to a different class and standing, within that class, at a lower or higher level of development.

The refined and active, on the other hand, prefer honour, which I suppose may be said to be the end of the political life. Yet honour is plainly too superficial to be the object of our search, because it appears to depend rather on those who give than on those who receive it, whereas we feel instinctively that the good must be something proper to a man, which cannot easily be taken from him.

Almost as soon as I began to study philosophy, I was impressed by the way in which philosophical problems appeared, disappeared, or changed shape, as a result of new assumptions or vocabularies.

It is so rare to meet with a man out-doors who cherishes a worthy thought in his mind, which is independent of the labor of his hands.

I do not believe that the source of value is unitary - displaying apparent multiplicity only in its application to the world. I believe that value has fundamentally different kinds of sources, and that they are reflected in the classification of values into types. Not all values represent the pursuit of some single good in a variety of settings.

The science which has to do with nature clearly concerns itself for the most part with bodies and magnitudes and their properties and movements, but also with the principles of this sort of substance, as many as they may be.

You are the salt of the earth; but if the salt loses its flavor, how shall it be seasoned? It is then good for nothing but to be thrown out and trampled underfoot by men. You are the light of the world. A city that is set on a hill cannot be hidden. Nor do they light a lamp and put it under a basket, but on a lampstand, and it gives light to all who are in the house. Let your light so shine before men, that they may see your good works and glorify your Father in heaven. Matthew 5:13-16 (NIV) (See also: Mark 9:50; Luke 14:34, 35)

As far as men go, it is not what they are that interests me, but what they can become.

Staying as I am, one foot in one country and the other in another, I find my condition very happy, in that it is free.

A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. By this shall all men know that ye are my disciples, if ye have love one to another. 13:34-35 KJV

What a monstrous thing that a University should teach journalism! I thought that was only done at Oxford. This respect for the filthy multitude is ruining civilisation.

The nature of power is such that even those who have not sought it, but have had it forced upon them, tend to acquire a taste for more.

But by far the greatest hindrance and aberration of the human understanding proceeds from the dullness, incompetency, and deceptions of the senses; in that things which strike the sense outweigh things which do not immediately strike it, though they be more important. Hence it is that speculation commonly ceases where sight ceases; insomuch that of things invisible there is little or no observation.

That the sun will not rise to-morrow is no less intelligible a proposition, and implies no contradiction, than the affirmation, that it will rise.

By this means all knowledge degenerates into probability; and this probability is greater or less, according to our experience of the veracity or deceitfulness of our understanding, and according to the simplicity or intricacy of the question.

The war against war is going to be no holiday excursion or camping party. The military feelings are too deeply grounded to abdicate their place among our ideals until better substitutes are offered than the glory and shame that come to nations as well as to individuals from the ups and downs of politics and the vicissitudes of trade.

The third of this kind of principles is : matter neither originates nor perishes; all the changes in the world concern form only ; a postulate which on the recommendation of common sense has spread through all philosophical schools, not because it is to be taken as having been found so, or as having been demonstrated by arguments a priori, but because if we were to admit that matter itself is fleeting and transitory, nothing at all that is stable and lasting would be left any longer to serve for the explication of phenomena according to universal and perpetual laws, and hence nothing at all would be left for the exercise of the intellect.

Do not be arrogant because of your knowledge, but confer with the ignorant man as with the learned. For knowledge has no limits, and none has yet achieved perfection in it. Good speech is more hidden than malachite, yet it is found in the possession of women slaves at the millstones.

Those who claim to care about the wellbeing of human beings and the preservation of our environment should become vegetarians for that reason alone. They would thereby increase the amount of grain available to feed people elsewhere, reduce pollution, save water and energy, and cease contributing to the clearing of forests; moreover, since a vegetarian diet is cheaper than one based on meat dishes, they would have more money available to devote to famine relief, population control, or whatever social or political cause they thought most urgent. ... when nonvegetarians say that "human problems come first" I cannot help wondering what exactly it is that they are doing for human beings that compels them to continue to support the wasteful, ruthless exploitation of farm animals.

Do not hire a man who does your work for money, but him who does it for love of it.

I have read in Plato and Cicero sayings that are very wise and very beautiful; but I never read in either of them, "Come unto me, all ye that labor and are heavy laden."

What peculiar privilege has this little agitation of the brain which we call thought, that we must thus make it the model of the whole universe? Our partiality in our own favour does indeed present it on all occasions; but sound philosophy ought carefully to guard against so natural an illusion.

I have been writing & speaking what were once called novelties, for twenty five or thirty years, & have not now one disciple. Why? Not that what I said was not true; not that it has not found intelligent receivers but because it did not go from any wish in me to bring men to me, but to themselves. I delight in driving them from me. What could I do, if they came to me? - they would interrupt and encumber me. This is my boast that I have no school & no follower. I should account it a measure of the impurity of insight, if it did not create independence.

All men would then be necessarily equal, if they were without needs. It is the poverty connected with our species which subordinates one man to another. It is not inequality which is the real misfortune, it is dependence.

The facts of science, as they appeared to him [Heraclitus], fed the flame in his soul, and in its light, he saw into the depths of the world.

The capitalist cannot store labour-power in warehouses after he has bought it, as he may do with the raw material.

What is the essence of life? To serve others and to do good. Often given as a saying of Aristotle with no reference.

If we take a survey of ages and of countries, we shall find the women, almost - without exception - at all times and in all places, adored and oppressed. Man, who has never neglected an opportunity of exerting his power, in paying homage to their beauty, has always availed himself of their weakness He has been at once their tyrant and their slave.

Marriage is encouraged in China, not by the profitableness of children, but by the liberty of destroying them.

The Idols of the Cave are the idols of the individual man. For everyone (besides the errors common to human nature in general) has a cave or den of his own, which refracts and discolors the light of nature, owing either to his own proper and peculiar nature; or to his education and conversation with others; or to the reading of books, and the authority of those whom he esteems and admires; or to the differences of impressions, accordingly as they take place in a mind preoccupied and predisposed or in a mind indifferent and settled; or the like. So that the spirit of man (according as it is meted out to different individuals) is in fact a thing variable and full of perturbation, and governed as it were by chance. Whence it was well observed by Heraclitus that men look for sciences in their own lesser worlds, and not in the greater or common world.

Landlords... grow richer, as it were in their sleep, without working, risking, or economizing.

Many Catholic mystics have affirmed that, at a certain stage of that contemplative prayer in which, according to the most authoritative theologians, the life of Christian perfection ultimately consists, it is necessary to put aside all thought of the Incarnation as distracting from the higher knowledge of that which has been incarnated. From this fact have arisen misunderstandings in plenty and a number of intellectual difficulties.

A merchant, it has been said very properly, is not necessarily the citizen of any particular country.

Between the Shaman of the Tungus, the European prelate who rules church and state, the Voguls, and the Puritans, on the one hand, and the man who listens to his own command of duty, on the other, the difference is not that the former make themselves slaves, while the latter is free, but that the former have their lord outside themselves, while the latter carries his lord in himself, yet at the same time is his own slave.

The man who esteems himself as he ought, and no more than he ought, seldom fails to obtain from other people all the esteem that he himself thinks due. He desires no more than is due to him, and he rests upon it with complete satisfaction.

There have been men before ... who got so interested in proving the existence of God that they came to care nothing for God himself... as if the good Lord had nothing to do but to exist. There have been some who were so preoccupied with spreading Christianity that they never gave a thought to Christ.

Only geometry can hand us the thread [which will lead us through] the labyrinth of the continuum's composition, the maximum and the minimum, the infinitesimal and the infinite; and no one will arrive at a truly solid metaphysic except he who has passed through this [labyrinth].

The wise is one only. It is unwilling and willing to be called by the name of Zeus.

Mother love is stronger than the filth and scabbiness on a child, and so the love of God toward us is stronger than the dirt that clings to us.

Wherever the want of clothing forced them to it, the human race made clothes for thousands of years, without a single man becoming a tailor.

The art of persuasion consists as much in that of pleasing as in that of convincing, so much more are men governed by caprice than by reason!

A reflective, contented mind is the best possession.

Eternity, not as a static "now," nor as a sequence of "nows" rolling off into the infinite, but as the "now" that bends back into itself. ... Thinking the most difficult thought of philosophy means thinking being as time.

Make thyself pure, 0 righteous man! Anyone in the world here below can win purity for himself, namely, when he cleanses himself with Good Thoughts, Good Words, and Good Deeds.

Beauty is the mark God sets upon virtue.

Reviewing what you have learned and learning anew, you are fit to be a teacher.

It pays to be obvious, especially if you have a reputation for subtlety.

While loving glory so much how can you persist in a plan which will cause you to lose it?

Virtue cannot dwell with wealth either in a city or in a house.

The problem of establishing a perfect civic constitution is dependent upon the problem of a lawful external relation among states and cannot be solved without a solution of the latter problem.
