Immanuel Kant Quotes

Simply to acquiesce in skepticism can never suffice to overcome the restlessness of reason.

Laziness and cowardice are the reasons why so great a portion of mankind, after nature has long since discharged them from external direction (naturaliter maiorennes), nevertheless remains under lifelong tutelage, and why it is so easy for others to set themselves up as their guardians. It is so easy not to be of age. If I have a book which understands for me, a pastor who has a conscience for me, a physician who decides my diet, and so forth, I need not trouble myself. I need not think, if I can only pay - others will easily undertake the irksome work for me.That the step to competence is held to be very dangerous by the far greater portion of mankind...

All our knowledge begins with the senses, proceeds then to the understanding, and ends with reason. There is nothing higher than reason.

From the crooked timber of humanity, a straight board cannot be hewn.

...[T]o be unfaithful to my maxim of prudence may often be very advantageous to me, although to abide by it is certainly safer.

A good will is good not because of what it performs or effects, not by its aptness for the attainment of some proposed end, but simply by virtue of the volition - that is, it is good in itself, and considered by itself is to be esteemed much higher than all that can be brought about by it in favor of any inclination, nay, even of the sum-total of all inclinations... like a jewel, it would still shine by its own light, as a thing which has its whole value in itself.

High towers, and metaphysically-great men resembling them, round both of which there is commonly much wind, are not for me. My place is the fruitful bathos, the bottom-land, of experience; and the word transcendental, does not signify something passing beyond all experience, but something that indeed precedes it a priori, but that is intended simply to make cognition of experience possible.

What is more, we cannot do morality a worse service than by seeing to derive it from examples. Every example of it presented to me must first itself be judged by moral principles in order to decide if it is fit to serve as an original example...even the Holy One of the gospel must first be compared with our ideal of moral perfection before we can recognize him to be such.

Since in early youth it cannot be known what ends are likely to occur to us in the course of life, parents seek to have their children taught a great many things, and provide for their skill in the use of means for all sorts of arbitrary ends, of none of which can they determine whether it may not perhaps hereafter be an object to determine their pupil, but which it is at all events possible that he might aim at; and this anxiety is so great that they commonly neglect to form and correct their judgement on the value of the things which may be chosen as ends.

It is impossible to conceive anything at all in the world, or even out of it, which can be taken as good without qualification, except a good will.

Enlightenment is man's emergence from his self-imposed nonage. Nonage is the inability to use one's own understanding without another's guidance. This nonage is self-imposed if its cause lies not in lack of understanding but in indecision and lack of courage to use one's own mind without another's guidance. Dare to know! (Sapere aude.) "Have the courage to use your own understanding," is therefore the motto of the enlightenment.

As nature has uncovered from under this hard shell the seed for which she most tenderly cares - the propensity and vocation to free thinking - this gradually works back upon the character of the people, who thereby gradually become capable of managing freedom; finally, it affects the principles of government, which finds it to its advantage to treat men, who are now more than machines, in accordance with their dignity.

Freedom is alone the unoriginated birthright of man, and belongs to him by force of his humanity; and is independent of the will and co-action of every other…

Dignity is a value that creates irreplaceability.

Everything in nature acts in conformity with law.

The death of dogma is the birth of reality.

...[W]e must admit that... law must be valid, not merely for men, but for all rational creatures generally, not merely under certain contingent conditions or with exceptions, but with absolute necessity...

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.

True politics cannot take a single step without first paying homage to morals, and while politics itself is a difficult art, its combination with morals is no art at all; for morals cuts the Gordian knot which politics cannot solve as soon as the two are in conflict.

...[R]eason of itself, independent on all experience, ordains what ought to take place, that accordingly actions of which perhaps the world has hitherto never given an example, the feasibility even if which might be very much doubted by one who founds everything on experience, are nevertheless inflexibly commanded by reason; that, for example, even though there might never yet have been a sincere friend, yet not a whit the less is pure sincerity in friendship required of every man...

The schematicism by which our understanding deals with the phenomenal world ... is a skill so deeply hidden in the human soul that we shall hardly guess the secret trick that Nature here employs.

But only he who, himself enlightened, is not afraid of shadows.

Only the descent into the hell of self-knowledge can pave the way to godliness.

Seek not the favor of the multitude; it is seldom got by honest and lawful means. But seek the testimony of few; and number not voices, but weigh them.

Without man and his potential for moral progress, the whole of reality would be a mere wilderness, a thing in vain, and have no final purpose.

He who would know the world must first manufacture it.
