All thought must, directly or indirectly, by way of certain characters, relate ultimately to intuitions, and therefore, with us, to sensibility, because in no other way can an object be given to us.
Immanuel Kant
-
The only thing that is good without qualification is a good will.
Immanuel Kant
-
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.
Immanuel Kant
-
Do what is right, though the world may perish.
Immanuel Kant
-
Aristotle can be regarded as the father of logic. But his logic is too scholastic, full of subtleties, and fundamentally has not been of much value to the human understanding. It is a dialectic and an organon for the art of disputation.
Immanuel Kant
-
A categorical imperative would be one which represented an action as objectively necessary in itself, without reference to any other purpose.
Immanuel Kant
-
There will always be some people who think for themselves, even among the self-appointed guardians of the great mass who, after having thrown off the yoke of immaturity themselves, will spread about them the spirit of a reasonable estimate of their own value and of the need for every man to think for himself.
Immanuel Kant
-
Die Verehrung mächtiger unsichtbarer Wesen, welche dem hülflosen Menschen durch die natürliche, auf dem Bewusstsein seines Unvermögens gegründete Furcht abgenöthigt wurde, …
Immanuel Kant
-
One cannot avoid a certain feeling of disgust, when one observes the actions of man displayed on the great stage of the world. Wisdom is manifested by individuals here and there; but the web of human history as a whole appears to be woven from folly and childish vanity, often, too, from puerile wickedness and love of destruction: with the result that at the end one is puzzled to know what idea to form of our species which prides itself so much on its advantages.
Immanuel Kant
-
Thus our duties to animals are indirectly duties to humanity.
Immanuel Kant
-
All our knowledge begins with the senses...
Immanuel Kant
-
Among all nations, through the darkest polytheism glimmer some faint sparks of monotheism.
Immanuel Kant
-
Prudence approaches, conscience accuses.
Immanuel Kant
-
This can never become popular, and, indeed, has no occasion to be so; for fine-spun arguments in favour of useful truths make just as little impression on the public mind as the equally subtle objections brought against these truths. On the other hand, since both inevitably force themselves on every man who rises to the height of speculation, it becomes the manifest duty of the schools to enter upon a thorough investigation of the rights of speculative reason, and thus to prevent the scandal which metaphysical controversies are sure, sooner or later, to cause even to the masses.
Immanuel Kant
-
So act that your principle of action might safely be made a law for the whole world.
Immanuel Kant
-
In the metaphysical elements of aesthetics the various nonmoral feelings are to be made use of; in the elements of moral metaphysics the various moral feelings of men, according to the differences in sex, age, education, and government, of races and climates, are to be employed.
Immanuel Kant
-
All natural philosophers, who wished to proceed mathematically in their work, have hence invariably (although unknown to themselves) made use of metaphysical principles, and must make use of such, it matters not how energetically they may otherwise repudiate any claim of metaphysics on their science.
Immanuel Kant
-
Psychologists have hitherto failed to realize that imagination is a necessary ingredient of perception itself.
Immanuel Kant
-
From such crooked wood as that which man is made of, nothing straight can be fashioned.
Immanuel Kant
-
Nature has willed that man should, by himself, produce everything that goes beyond the mechanical ordering of his animal existence, and that he should partake of no other happiness or perfection than that which he himself, independently of instinct, has created by his own reason.
Immanuel Kant
-
Natural science is throughout either a pure or an applied doctrine of motion.
Immanuel Kant
-
Two things fill the mind with ever new and increasing admiration and awe, the more often and steadily we reflect upon them: the starry heavens above me and the moral law within me. I do not seek or conjecture either of them as if they were veiled obscurities or extravagances beyond the horizon of my vision; I see them before me and connect them immediately with the consciousness of my existence.
Immanuel Kant
-
What are the aims which are at the same time duties? They are perfecting of ourselves, the happiness of others.
Immanuel Kant
-
No-one can compel me to be happy in accordance with his conception of the welfare of others, for each may seek his happiness in whatever way he sees fit, so long as he does not infringe upon the freedom of others to pursue a similar end which can be reconciled with the freedom of everyone else within a workable general law ? i.e. he must accord to others the same right as he enjoys himself.
Immanuel Kant
