Kant speaks of the "thing-in-itself" (Ding an sich) in order to distinguish it from the "thing-for-us" (Ding fur uns), that is, as a "phenomenon." A thing-in-itself is that which is not approachable through experience as are the rocks, plants, and animals. Every thing-for-us is as a thing and also a thing-in-itself, which means that it is recognized absolutely withing the absolute knowledge of God. But not every thing-in-itself is also a thing-for-us: God, for instance, is a thing-in-itself, as Kant uses the word, according to the meaning of Christian theology.

The new education must consist essentially in this, that it completely destroys freedom of will in the soil which it undertakes to cultivate, and produces on the contrary strict necessity in the decisions of the will, the opposite being impossible. Such a will can henceforth be relied on with confidence and certainty.

Thus he had a double thought: the one by which he acted as king, the other by which he recognized his true state, and that it was accident alone that had placed him in his present condition.

The world is divided into men who have wit and no religion and men who have religion and no wit.

The fear of your own solitude, of its vast surface and its infinity... Remorse is the voice of solitude. And what does this whispering voice say? Everything in us that is not human anymore.

True science is distinctively the study of useless things. For the useful things will get studied without the aid of scientific men.

The introduction of free competition is thus public declaration that from now on the members of society are unequal only to the extent that their capitals are unequal, that capital is the decisive power, and that therefore the capitalists, the bourgeoisie, have become the first class in society. Free competition is necessary for the establishment of big industry, because it is the only condition of society in which big industry can make its way.

In each separate thing that you do consider the matters which come first, and those which follow after, and only then approach the thing itself.

Anyone can escape into sleep, we are all geniuses when we dream, the butcher's the poet's equal there.

That men do not learn very much from the lessons of history is the most important of all the lessons that history has to teach.

Oh, can I really believe the poet's tales, that when one first sees the object of one's love, one imagines one has seen her long ago, that all love like all knowledge is remembrance, that love too has its prophecies in the individual. ... it seems to me that I should have to possess the beauty of all girls in order to draw out a beauty equal to yours; that I should have to circumnavigate the world in order to find the place I lack and which the deepest mystery of my whole being points towards, and at the next moment you are so near to me, filling my spirit so powerfully that I am transfigured for myself, and feel that it's good to be here.

Whatever we know without inference is mental.

The ceremonial (hot or cold) as opposed to the haphazard (lukewarm) characterizes piety.

The first law that ever God gave to man was a law of pure obedience; it was a commandment naked and simple, wherein man had nothing to inquire after, nor to dispute; forasmuch as to obey is the proper office of a rational soul, acknowledging a heavenly superior and benefactor.

Citizens of a Jeffersonian democracy can be as religious or irreligious as they please as long as they are not "fanatical." That is, they must abandon or modify opinion on matters of ultimate importance, the opinions that may hitherto have given sense and point to their lives, if these opinions entail public actions that cannot be justified to most of their fellow citizens.

Let us keep to Christ, and cling to Him, and hang on Him, so that no power can remove us.

Whatever is supreme in a state, ought to have, as much as possible, its judicial authority so constituted as not only not to depend upon it, but in some sort to balance it. It ought to give a security to its justice against its power. It ought to make its judicature, as it were, something exterior to the state.

Big industry, freed from the pressure of private property, will undergo such an expansion that what we now see will seem as petty in comparison as manufacture seems when put beside the big industry of our own day. This development of industry will make available to society a sufficient mass of products to satisfy the needs of everyone. The same will be true of agriculture, which also suffers from the pressure of private property and is held back by the division of privately owned land into small parcels. Here, existing improvements and scientific procedures will be put into practice, with a resulting leap forward which will assure to society all the products it needs. In this way, such an abundance of goods will be able to satisfy the needs of all its members.

The value of a principle is the number of things it will explain; and there is no good theory of disease which does not at once suggest a cure.

For Warre, consisteth not in Battell onely, or the act of fighting; but in a tract of time, wherein the Will to contend by Battell is sufficiently known: and therefore the notion of Time, is to be considered in the nature of Warre; as it is in the nature of Weather.

Science raises itself above all Ages and all Times, embracing and apprehending the ONE UNCHANGING TIME as the higher source of all Ages and Epochs, and grasping that vast idea in its free, unbounded comprehension.

Each to each a looking-glass, Reflects his figure that doth pass. Every wayfarer he meets What himself declared repeats, What himself confessed records, Sentences him in his words; The form is his own corporal form, And his thought the penal worm. Yet shine forever virgin minds, Loved by stars and the purest winds, Which, o'er passion throned sedate, Have not hazarded their state; Disconcert the searching spy, Rendering to a curious eye The durance of a granite ledge To those who gaze from the sea's edge. It is there for benefit; It is there for purging light; There for purifying storms; And its depths reflect all forms; It cannot parley with the mean,- Pure by impure is not seen. For there's no sequestered grot, Lone mountain tarn, or isle forgot, But Justice, journeying in the sphere, Daily stoops to harbour there.

What defects women have, we must check them for in private, gently by word of mouth, for woman is a frail vessel.

If you make the same guess often enough it ceases to be a guess and becomes a Scientific Fact. This is the inductive method.

We ought so to behave to one another as to avoid making enemies of our friends, and at the same time to make friends of our enemies. As quoted in Diogenes Laërtius, Lives and Opinions of Eminent Philosophers, "Pythagoras", Sect. 23, as translated in Dictionary of Quotations (1906) by Thomas Benfield Harbottle, p. 320

During such calm sunshine of the mind, these spectres of false divinity never make their appearance.

I took some pains to convince you that the Whigs, as a party in the state, were of the highest value to the public welfare, and constituted the party to which a liberal-minded and enlightened man would adhere.

The organism does not have a point of view: the person or creature does.

Every revolutionary ends as an oppressor or a heretic.

For what is it that everyone is seeking? To live securely, to be happy, to do everything as they wish to do, not to be hindered, not to be subject to compulsion.

The origin of things, considered not as leading to anything, but in itself, contains the idea of First, the end of things that of Second, the process mediating between them that of Third. A philosophy which emphasises the idea of the One, is generally a dualistic philosophy in which the conception of Second receives exaggerated attention: for this One (though of course involving the idea of First) is always the other of a manifold which is not one. The idea of the Many, because variety is arbitrariness and arbitrariness is repudiation of any Secondness, has for its principal component the conception of First. In psychology Feeling is First, Sense of reaction Second, General conception Third, or mediation. In biology, the idea of arbitrary sporting is First, heredity is Second, the process whereby the accidental characters become fixed is Third. Chance is First, Law is Second, the tendency to take habits is Third. Mind is First, Matter is Second, Evolution is Third.

I've got a one-dimensional mind.

Now, to-day, this moment, is our chance to choose the right side. God is holding back to give us that chance. It will not last for ever. We must take it or leave it.

You must learn all things, both the unshaken heart of persuasive truth, and the opinions of mortals in which there is no true warranty.

Most human beings have an almost infinite capacity for taking things for granted.

When the happiness or misery of others depends in any respect upon our conduct, we dare not, as self-love might suggest to us, prefer the interest of one to that of many. The man within immediately calls to us, that we value ourselves too much and other people too little, and that, by doing so, we render ourselves the proper object of the contempt and indignation of our brethren. Neither is this sentiment confined to men of extraordinary magnanimity and virtue. It is deeply impressed upon every tolerably good soldier, who feels that he would become the scorn of his companions, if he could be supposed capable of shrinking from danger, or of hesitating, either to expose or to throw away his life, when the good of the service required it.

In conditions of private property ... "life-activity" stands in the service of property instead of property standing the service of free life-activity.

Every other art,-as poetry, music, painting,-may be practised without the process showing forth the rules according to which it is conducted ;-but in the self-cognizant art of the philosopher, no step can be taken without declaring the grounds upon which it proceeds.

The total possible consciousness may be split into parts which co-exist but mutually ignore each other.

And having looked to Government for bread, on the very first scarcity they will turn and bite the hand that fed them.

Good is a good doctor, but Bad is sometimes a better.

It is the destiny of our race to become united into one great body, thoroughly connected in all its parts, and possessed of similar culture. Nature, and even the passions and vices of Man, have from the beginning tended towards this end. A great part of the way towards it is already passed, and we may surely calculate that it will in time be reached.

The Ideal Man of the eighteenth century was the Rationalist; of the seventeenth, the Christian Stoic; of the Renaissance, the Free Individual; of the Middle Ages, the Contemplative Saint. And what is our Ideal Man? On what grand and luminous mythological figure does contemporary humanity attempt to model itself? The question is embarrassing. Nobody knows. And, in spite of all the laudable efforts of the Institute for Intellectual Co-operation to fabricate an acceptable Ideal Man for the use of Ministers of Education, nobody, I suspect, will know until such time as a major poet appears upon the scene with the unmistakable revelation. Meanwhile, one must be content to go on piping up for reason and realism and a certain decency.

To live in a saint's heart? I'm afraid of setting the sky ablaze.

It seems to me that the current political task in a society like ours is to criticize the working of institutions that are apparently the most neutral and independent, to criticize these institutions and attack them in such a way that the political violence that exercises itself obscurely through them becomes manifest, so that one can fight against them.

Let us not pretend to doubt in philosophy what we do not doubt in our hearts.

Avarice and injustice are always shortsighted, and they did not foresee how much this regulation must obstruct improvement, and thereby hurt in the long-run the real interest of the landlord.

Even if a civil society were to be dissolved by the consent of all its members (e.g., if a people inhabiting an island decided to separate and disperse throughout the world), the last murderer remaining in prison would first have to be executed, so that each has done to him what his deeds deserve and blood guilt does not cling to the people for not having insisted upon this punishment; for otherwise the people can be regarded as collaborators in his public violation of justice.

Nostalgia, more than anything, gives us the shudder of our own imperfection.

The end of living, or the ultimate good, which is to be sought for its own sake, according to the universal opinion of mankind, is happiness; yet men, for the most part, fail in the pursuit of this end, either because they do not form a right idea of the nature of happiness, or because they do not make use of proper means to attain it.
