Immanuel Kant quotes

He [Jesus] claims that not the observance of outer civil or statutory churchly duties but the pure moral disposition of the heart alone can make man well-pleasing to God (Matthew V, 20-48); … that injury done one’s neighbor can be repaired only through satisfaction rendered to the neighbor himself, not through acts of divine worship (V, 24). Thus, he says, does he intend to do full justice to the Jewish law (V, 17); whence it is obvious that not scriptural scholarship but the pure religion of reason must be the law’s interpreter, for taken according to the letter, it allowed the very opposite of all this. Furthermore, he does not leave unnoticed, in his designations of the strait gate and the narrow way, the misconstruction of the law which men allow themselves in order to evade their true moral duty, holding themselves immune through having fulfilled their churchly duty (VII, 13). He further requires of these pure dispositions that they manifest themselves also in works (VII, 16) and, on the other hand, denies the insidious hope of those who imagine that, through invocation and praise of the Supreme Lawgiver in the person of His envoy, they will make up for their lack of good works and ingratiate themselves into favor (VII, 21). Regarding these works he declares that they ought to be performed publicly, as an example for imitation (V, 16), and in a cheerful mood, not as actions extorted from slaves (VI, 16); and that thus, from a small beginning in the sharing and spreading of such dispositions, religion, like a grain of seed in good soil, or a ferment of goodness, would gradually, through its inner power, grow into a kingdom of God (XIII, 31-33).

Die Verehrung mächtiger unsichtbarer Wesen, welche dem hülflosen Menschen durch die natürliche, auf dem Bewusstsein seines Unvermögens gegründete Furcht abgenöthigt wurde, …

Human reason has this peculiar fate that in one species of its knowledge it is burdened by questions which, as prescribed by the very nature of reason itself, it is not able to ignore, but which, as transcending all its powers, it is also not able to answer.

Character means that the person derives his rules of conduct from himself and from the dignity of humanity. Character is the common ruling principle in man in the use of his talents and attributes. Thus it is the nature of his will, and is good or bad. A man who acts without settled principles, with no uniformity, has no character. A man may have a good heart and yet no character, because he is dependent upon impulses and does not act according to maxims. Firmness and unity of principle are essential to character.

Even philosophers will praise war as ennobling mankind, forgetting the Greek who said: War is bad in that it begets more evil than it kills.

To be is to do.

Morality is not properly the doctrine of how we may make ourselves happy, but how we may make ourselves worthy of happiness.

Man's greatest concern is to know how he shall properly fill his place in the universe and correctly understand what he must be in order to be a man.

There can be no doubt that all our knowledge begins with experience.

Freedom is the alone unoriginated birthright of man, and belongs to him by force of his humanity; and is independence on the will and co-action of every other in so far as this consists with every other person’s freedom.

Thoughts without content are empty, intuitions without concepts are blind. The understanding can intuit nothing, the senses can think nothing. Only through their unison can knowledge arise.

All natural capacities of a creature are destined to evolve completely to their natural end.

Happiness is not an ideal of reason but of imagination.

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.

I have no knowledge of myself as I am, but merely as I appear to myself.

Two things fill the mind with ever-increasing wonder and awe, the more often and the more intensely the mind of thought is drawn to them: the starry heavens above me and the moral law within me.

The more one presupposes that his own power will suffice him to realize what he desires the more practical is that desire. When I treat a man contemptuously, I can inspire him with no practical desire to appreciate my grounds of truth. When I treat any one as worthless, I can inspire him with no desire to do right.

It is difficult for the isolated individual to work himself out of the immaturity which has become almost natural for him. He has even become fond of it and for the time being is incapable of employing his own intelligence, because he has never been allowed to make the attempt. Statutes and formulas, these mechanical tools of a serviceable use, or rather misuse, of his natural faculties, are the ankle-chains of a continuous immaturity. Whoever threw it off would make an uncertain jump over the smallest trench because he is not accustomed to such free movement. Therefore there are only a few who have pursued a firm path and have succeeded in escaping from immaturity by their own cultivation of the mind.

Beneficence is a duty. He who often practices this, and sees his beneficent purpose succeed, comes at last really to love him whom he has benefited. When, therefore, it is said, "Thou shalt love thy neighbor as thyself," this does not mean, "Thou shalt first of all love, and by means of love (in the next place) do him good"; but: "Do good to thy neighbour, and this beneficence will produce in thee the love of men (as a settled habit of inclination to beneficence)."

Psychologists have hitherto failed to realize that imagination is a necessary ingredient of perception itself.
