Formerly, it was held by philosophers and mathematicians alike that the proofs in Geometry depended on the figure; nowadays, this is known to be false. In the best books there are no figures at all. The reasoning proceeds by the strict rules of formal logic from a set of axioms laid down to begin with.

Being happy involves both a certain achievement in action and a rational assurance about the outcome.

I call upon you, young men, to obey your heart, and be the nobility of this land. In every age of the world, there has been a leading nation, one of a more generous sentiment, whose eminent citizens were willing to stand for the interests of general justice and humanity, at the risk of being called, by the men of the moment, chimerical and fantastic. Which should be that nation but these States? Which should lead that movement, if not New England? Who should lead the leaders, but the Young American?

He who postpones the hour of living rightly is like the rustic who waits for the river to run out before he crosses.

That which parents should take care of... is to distinguish between the wants of fancy, and those of nature.

What is a weed? A plant whose virtues have yet to be discovered.

Hear first the four roots of all things: shining Zeus, life-bringing Hera, Aidoneus, and Nestis, who wets with tears the mortal wellspring.

Sex also concentrates the mind wonderfully, and that is why civilised man is so obsessed by it. It enables him to "savour every fraction of an inch," not merely of the act of sexual intercourse, but of living itself. But that, of course, only underlines the basic problem: after coitus, "man becomes sad," because he quickly returns to his unconcentrated and defocused state. In sexual excitement, it is the spirit itself that becomes erect, and becomes capable of penetrating the meaning of life. Normal consciousness is limp and flaccid; its attitude towards reality is defensive. This is what Sartre called contingency, that feeling of being at the mercy of chance.

Their worship was not paid to the demon which such a being as they imagined would really be, but to their own idea of excellence. The evil is, that such a belief keeps the ideal wretchedly low; and opposes the most obstinate resistance to all thought which has a tendency to raise it higher. Believers shrink from every train of ideas which would lead the mind to a clear conception and an elevated standard of excellence, because they feel (even when they do not distinctly see) that such a standard would conflict with many of the dispensations of nature, and with much of what they are accustomed to consider as the Christian creed.

People are enticed by a desire which continually cheats them.'Nothing is enough,' they say, 'for you're only worth what you have.'

The mind celebrates a little triumph whenever it can formulate a truth, however unwelcome to the flesh, or discover an actual force, however unfavourable to given interests.

Logical analysis applied to mental phenomenon shows that there is but one law of mind, namely that ideas tend to spread continuously and to affect certain others which stand to them in a peculiar relation of affectibility. In this spreading they lose intensity, and especially the power of affecting others, but gain generality and become welded with other ideas.

The criticism of the reformers was directed not so much at the weakness or cruelty of those in authority, as at a bad economy of power.

That which distinguishes the Christian narrow way from the common human narrow way is the voluntary. Christ was not someone who coveted earthly things but had to be satisfied with poverty, no, he chose poverty.

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.

...he always firmly believed that they were purely on the defensive in that rebellion. He considered the Americans as standing at that time, and in that controversy, in the same relation to England, as England did to king James the Second, in 1688.

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.

Absurdity destroys the and of the enumeration by making impossible the in where the things enumerated would be divided up.

The smartphone seems to be a playground, but it is a digital panopticon.

I have resolved to demonstrate by a certain and undoubted course of argument, or to deduce from the very condition of human nature, not what is new and unheard of, but only such things as agree best with practice.

In old days the plastic arts, music, and poesy were so germane to man in his totality that his Transcendence plainly manifest in them. ... What is to-day obvious to all is a decay in the essence of art. ... the opposition to man's true nature as man.

May it not be the fact that mankind, who after all are made up of single human beings, obtain a greater sum of happiness when each pursues his own, under the rules and conditions required by the good of the rest, than when each makes the good of the rest his only object, and allows himself no personal pleasures not indispensable to the preservation of his faculties? The regimen of a blockaded town should be cheerfully submitted to when high purposes require it, but is it the ideal perfection of human existence?

I think no virtue goes with size; The reason of all cowardice Is, that men are overgrown, And, to be valiant, must come down To the titmouse dimension.

Things have their root and their branches. Affairs have their end and their beginning. To know what is first and what is last will lead near to what is taught in the Great Learning.

For some identify happiness with virtue, some with practical wisdom, others with a kind of philosophic wisdom, others with these, or one of these, accompanied by pleasure or not without pleasure; while others include also external prosperity. Now ... it is not probable that these should be entirely mistaken, but rather that they should be right in at least some one respect or even in most respects.

Scepticism is not irrefutable, but obviously nonsensical, when it tries to raise doubts where no questions can be asked. For doubt can exist only where a question exists, a question only where an answer exists, and an answer only where something can be said.

I think they do it to pass the time, nothing more. But time is too large, it can't be filled up. Everything you plunge into it is stretched and disintegrates.

To live without duties is obscene.

The ceaseless labour of your life is to build the house of death.

Conduct, practice, is the proof of doctrine, theory. "If any man will do His will - the will of Him that sent me," said Jesus, "he shall know of the doctrine, whether it be of God or whether I speak of myself" (John vii. 17); and there is a well known saying of Pascal: "Begin by taking holy water and you will end by becoming a believer." And pursuing a similar train of thought, Johann Jakob Moser, the pietist, was of the opinion that no atheist or naturalist had the right to regard the Christian religion as void of truth so long as he had not put it to the proof by keeping its precepts and commandments.

As an empiricist I continue to think of the conceptual scheme of science as a tool, ultimately, for predicting future experience in the light of past experience. Physical objects are conceptually imported into the situation as convenient intermediaries-not by definition in terms of experience, but simply as irreducible posits comparable, epistemologically, to the gods of Homer. For my part I do, qua lay physicist, believe in physical objects and not in Homer's gods; and I consider it a scientific error to believe otherwise. But in point of epistemological footing the physical objects and the gods differ only in degree and not in kind. Both sorts of entities enter our conception only as cultural posits. The myth of physical objects is epistemologically superior to most in that it has proved more efficacious than other myths as a device for working a manageable structure into the flux of experience.

In writing what he does not speak, what he would never say and, in truth, would probably never even think, the author of the written speech is already entrenched in the posture of the sophist; the man of non-presence and non-truth. Writing is thus already on the scene. The incompatibility between written and the true is clearly announced at the moment Socrates starts to recount the way in which men are carried out themselves by pleasure, become absent from themselves, forget themselves and die in the thrill of song.

Several excuses are always less convincing than one.

Some minds will jump here jump to the conclusion that a past idea cannot in any sense be present. But that is hasty and illogical. How extravagant too, to pronounce our whole knowledge of the past to be mere delusion! Yet it would seem that the past is completely beyond the bounds of possible experience as a Kantian thing-in-itself.

Wilt thou seal up the avenues of ill? Pay every debt as if God wrote the bill.

Man has his own inclinations and a natural will which, in his actions, by means of his free choice, he follows and directs. There can be nothing more dreadful than that the actions of one man should be subject to the will of another; hence no abhorrence can be more natural than that which a man has for slavery. And it is for this reason that a child cries and becomes embittered when he must do what others wish, when no one has taken the trouble to make it agreeable to him. He wants to be a man soon, so that he can do as he himself likes.

Our institutions and conditions rest upon deep-seated ideas. To change those conditions and at the same time leave the underlying ideas and values intact means only a superficial transformation, one that cannot be permanent or bring real betterment. It is a change of form only, not of substance, as so tragically proven by Russia.

Money is a crystal formed of necessity in the course of the exchanges, whereby different products of labour are practically equated to one another and thus by practice converted into commodities.

What is the wisdom of a book compared with the wisdom of an angel?

The kind of relatedness to the world may be noble or trivial, but even being related to the basest kind of pattern is immensely preferable to being alone.

I do not wish to force my thoughts upon you, but I feel forced myself. Little as I know of Captain Brown, I would fain do my part to correct the tone and the statements of the newspapers, and of my countrymen generally, respecting his character and actions. It costs us nothing to be just. We can at least express our sympathy with, and admiration of, him and his companions, and that is what I now propose to do.

Equity knows no difference of sex. In its vocabulary the word man must be understood in a generic, and not in a specific sense.

Then I dreamed that one day there was nothing but milk for them and the jailer said as he put down the pipkin:'Our relations with the cow are not delicate-as you can easily see if you imagine eating any of her other secretions.' ... John said, 'Thank heavens! Now at last I know that you are talking nonsense. You are trying to pretend that unlike things are like. You are trying to make us think that milk is the same sort of thing as sweat or dung.' 'And pray, what difference is there except by custom?''Are you a liar or only a fool, that you see no difference between that which Nature casts out as refuse and that which she stores up as food?'

Love and the gracious heart are a single thing...one can no more be without the otherthan the reasoning mind without its reason.

All is in a man's hands and he lets it all slip from cowardice, that's an axiom. It would be interesting to know what it is men are most afraid of. Taking a new step, uttering a new word is what they fear most. Variant translation: "Taking a new step, uttering a new word, is what people fear most."

At the deepest level, the desire for complete union with God exhibits a narcissistic structure.

Just as man as a social being, cannot in the long run exist without a tie to the community, so the individual will never find the real justification for his existence, and his own spiritual and moral autonomy, anywhere except in an extramundane principle capable of relativizing the overpowering influence of external factors.

Credulity in arts and opinions is likewise of two kinds viz., when men give too much belief to arts themselves, or to certain authors in any art. The sciences that sway the imagination more than the reason are principally three viz., astrology, natural magic, and alchemy. Alchemy may be compared to the man who told his sons that he had left them gold, buried somewhere in his vineyard; while they by digging found no gold, but by turning up the mould about the roots of the vines procured a plentiful vintage. So the search and endeavours to make gold have brought many useful inventions to light.

The vanity of the passing world and love are the two fundamental and heart-penetrating notes of true poetry. And they are two notes of which neither can be sounded without causing the other to vibrate. The feeling of the vanity of the passing world kindles love in us, the only thing that triumphs over the vain and transitory, the only thing that fills life again and eternalizes it.
