The essential nature (concerning the soul) cannot be corporeal, yet it is also clear that this soul is present in a particular bodily part, and this one of the parts having control over the rest (heart).

Science does not rest upon solid bedrock. The bold structure of its theories arises, as it were, above a swamp. It is like a building erected on piles. The piles are driven down from above into the swamp, but not down to any natural or 'given' base; and if we stop driving the piles deeper, it is not because we have reached firm ground. We simply stop when we are satisfied that the piles are firm enough to carry the structure, at least for the time being.

There are truths which are not for all men, nor for all times.

When one admits that nothing is certain one must, I think, also admit that some things are much more nearly certain than others. It is much more nearly certain that we are assembled here tonight than it is that this or that political party is in the right. Certainly there are degrees of certainty, and one should be very careful to emphasize that fact, because otherwise one is landed in an utter skepticism, and complete skepticism would, of course, be totally barren and completely useless.

When he was asked what advantage had accrued to him from philosophy, his answer was, "The ability to hold converse with myself."

My basis is supported by the authority of the greatest moralist of modern times; for such, undoubtedly, J. J. Rousseau is,-that profound reader of the human heart, who drew his wisdom not from books, but from life, and intended his doctrine not for the professorial chair, but for humanity; he, the foe of all prejudice, the foster-child of nature, whom alone she endowed with the gift of being able to moralise without tediousness, because he hit the truth and stirred the heart.

Lastly, we must also know what Baptism signifies, and why God has ordained just such external sign and ceremony for the Sacrament by which we are first received into the Christian Church. But the act or ceremony is this, that we are sunk under the water, which passes over us, and afterwards are drawn out again. These two parts, to be sunk under the water and drawn out again, signify the power and operation of Baptism, which is nothing else than putting to death the old Adam, and after that the resurrection of the new man, both of which must take place in us all our lives, so that a truly Christian life is nothing else than a daily baptism, once begun and ever to be continued.

Hear, and understand: Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man. 15:10-11 (KJV)

The man of virtue makes the difficulty to be overcome his first business, and success only a subsequent consideration: this may be called perfect virtue.

It is only he who is possessed of the most complete sincerity that can exist under heaven, who can give its full development to his nature. Able to give its full development to his own nature, he can do the same to the nature of other men. Able to give its full development to the nature of other men, he can give their full development to the natures of animals and things. Able to give their full development to the natures of creatures and things, he can assist the transforming and nourishing powers of Heaven and Earth. Able to assist the transforming and nourishing powers of Heaven and Earth, he may with Heaven and Earth form a ternion.

He who seeks equality between unequals seeks an absurdity.

For an author to write as he speaks is just as reprehensible as the opposite fault, to speak as he writes; for this gives a pedantic effect to what he says, and at the same time makes him hardly intelligible.

The wise through excess of wisdom is made a fool.

On James's view, "true" resembles "good" or "rational" in being a normative notion, a compliment paid to sentences that seem to be paying their way and that fit with other sentences which are doing so.

Beauty is the mark God sets upon virtue.

Our Traders in Men (an unnatural commodity!) must know the wickedness of that Slave-Trade, if they attend to reasoning, or the dictates of their own hearts; and such as shun and stiffle all these, wilfully sacrifice Conscience, and the character of integrity to that golden Idol.

Men are most apt to believe what they least understand.

Nature is the best posture-master.

Ye shall drink indeed of my cup, and be baptized with the baptism that I am baptized with: but to sit on my right hand, and on my left, is not mine to give, but it shall be given to them for whom it is prepared of my Father. 20:23 (KJV)

Fact be vertuous, or vicious, as Fortune pleaseth.

Kant was also quite aware that "the urgent need" of reason is both different from and "more than mere quest and desire for knowledge." Hence, the distinguishing of the two faculties, reason and intellect, coincides with a distinction between two altogether different mental activities, thinking and knowing.

When the qualification to vote is regulated by years, it is placed on the firmest possible ground, because the qualification is such as nothing but dying before the time can take away; and the equality of Rights, as a principle, is recognized in the act of regulating the exercise. But when Rights are placed upon, or made dependent upon property, they are on the most precarious of all tenures. "Riches make themselves wings, and fly away," and the rights fly with them ; and thus they become lost to the man when they would be of most value.

England and France, the two most civilized nations on earth, who are in contrast to each other because of their different characters, are, perhaps chiefly for that reason, in constant feud with one another. Also, England and France, because of their inborn characters, of which the acquired and artificial character is only the result, are probably the only nations who can be assumed to have a particular and, as long as both national characters are not blended by the force of war, unalterable characteristics. That French has become the universal language of conversation, especially in the feminine world, and that English is the most widely used language of commerce among tradesmen, probably reflects the difference in their continental and insular geographic situation.

Wit is cultured insolence.

Books must follow sciences, and not sciences books.

Human beings have faculties more elevated than the animal appetites, and when once made conscious of them, do not regard anything as happiness which does not include their gratification. I do not, indeed, consider the Epicureans to have been by any means faultless in drawing out their scheme of consequences from the utilitarian principle. To do this in any sufficient manner, many Stoic, as well as Christian elements require to be included. But there is no known Epicurean theory of life which does not assign to the pleasures of the intellect, of the feelings and imagination, and of the moral sentiments, a much higher value as pleasures than to those of mere sensation.

You could attach prices to thoughts. Some cost a lot, some a little. And how does one pay for thoughts? The answer, I think, is: with courage.

...in order to change poverty into wealth, one must start by displaying it.

Next to the originator of a good sentence is the first quoter of it.

Even if there never have been actions arising from such pure sources, what is at issue here is not whether this or that happened; that, instead, reason by itself and independently of all appearances commands what ought to happen; that, accordingly, actions of which the world has perhaps so far given no example, and whose very practicability might be very much doubted by one who bases everything on experience, are still inflexibly commanded by reason ... because ... duty ... lies, prior to all experience, in the idea of a reason determing the will by means of apriori grounds.

What, then, of human activities? Is humankind itself hastening its own end? Man has, for instance, been burning carbon-containing fuel — wood, coal, oil, gas — at a steadily accelerating rate. All these fuels form carbon dioxide. Some is absorbed by plants and the oceans but not as fast as it is produced. This means the carbon dioxide content of the air is going up — slightly but nevertheless up. Carbon dioxide retains heat, and even a small rise means a warming of the Earth's atmosphere. This may result in the melting of the polar ice caps with unusual speed, flooding the world before we have learned climate control. In reverse, our industrial civilization is making our atmosphere dustier so that it reflects more sunlight away and cools the Earth slightly — thus making possible a glacial advance in a few centuries, also before we have learned climate control.

Freedom comes only to those who no longer ask of life that it shall yield them any of those personal goods that are subject to the mutations of time.

We are speaking on this occasion, not as members of this or that nation, continent, or creed, but as human beings, members of the species Man, whose continued existence is in doubt.

A thing forgotten on one day will be remembered on the next. Something we have made the most strenuous efforts to recall, but all in vain, will, soon after... saunter into the mind... [T]he sphere of possible recollection may be wider than we think, and... apparent oblivion is no proof against possible recall under other conditions.

A man might say, with enough truth to justify a joke: "Science is what we know, and philosophy is what we don't know." But it should be added that philosophical speculation as to what we do not yet know has shown itself a valuable preliminary to exact scientific knowledge.

We are in hell and I will have my turn!

Everything functions. That is exactly what is uncanny. Everything functions and the functioning drives us further and further to more functioning, and technology tears people away and uproots them from the Earth more and more. I don't know if you are scared; I was certainly scared when I recently saw the photographs of the Earth taken from the Moon. We don't need an atom bomb at all; the uprooting of human beings is already taking place. We only have purely technological conditions left. It is no longer an earth on which human beings live today.

Science does not stand still, and neither does philosophy, although the latter has a tendency to walk in circles.

We are not necessarily doubting that God will do the best for us; we are wondering how painful the best will turn out to be.

We must have kings, and we must have nobles. Nature provides such in every society, - only let us have the real instead of the titular. Let us have our leading and our inspiration from the best. In every society some men are born to rule, and some to advise. Let the powers be well directed, directed by love, and they would everywhere be greeted with joy and honor.

Nature magically suits the man to his fortunes, by making these the fruit of his character.

The weapon of criticism obviously cannot replace the criticism of weapons. Material force can only be overthrown by material force, but theory itself becomes a material force when it has gripped the masses. Theory is capable of gripping the masses when it demonstrates ad hominem, and it demonstrates ad hominem, when it becomes radical. To be radical is to grasp things by the root, but for man the root is man himself. The clear proof of the radicalism of German theory, and hence of its political energy, is that it proceeds from the decisive positive abolition of religion.

The meaning of a question is the method of answering it: then what is the meaning of 'Do two men really mean the same by the word "white"?' Tell me how you are searching, and I will tell you what you are searching for.

Truth never turns to rebuke falsehood; her own straightforwardness is the severest correction.

No one deserves his greater natural capacity nor merits a more favorable starting place in society.

There is no word or action but has its echo in Eternity. Thought is an Idea in transit, which when once released, never can be lured back, nor the spoken word recalled. Nor ever can the overt act be erased All that thou thinkest, sayest, or doest bears perpetual record of itself, enduring for Eternity.

Free in this world as the birds in the air, disengaged from every kind of chains, those who have practiced the Yoga gather in Brahmin the certain fruit of their works. Depend upon it; rude and careless as I am, I would fain practice the yoga faithfully. This Yogi, absorbed in contemplation, contributes in his degree to creation; he breathes a divine perfume, he heard wonderful things. Divine forms traverse him without tearing him and he goes, he acts as animating original matter. To some extent, and at rare intervals, even I am a Yogi.

If any philosopher had been asked for a definition of infinity, he might have produced some unintelligible rigmarole, but he would certainly not have been able to give a definition that had any meaning at all.

The means employed by Nature to bring about the development of all the capacities of men is their antagonism in society, so far as this is, in the end, the cause of a lawful order among men.
