Immanuel Kant Quotes

Freedom is the opposite of necessity.

(On the seeming futility of metaphysics) Why then has nature afflicted our reason with the restless striving for such a path, as if it were one of reason's most important occupations? Still more, how little cause have we to place trust in our reason if in one of the most important parts of our desire for knowledge it does not merely forsake us but even entices us with delusions and in the end betrays us!

Or if the path has merely eluded us so far, what indications may we use that might lead us to hope that in renewed attempts we will be luckier than those who have gone before us?

Hence we may at once dismiss as easily foreseen but futile objection, “that by our admitting the ideality of space and of time the whole sensible world would be turned into mere illusion.

But, though all our knowledge begins with experience, it by no means follows that all arises out of experience.

For with regard to nature, it is indeed experience which supplies us with the rule and is the source of truth; with regard to moral laws, however, experience is, alas!, but the mother of illusion; and it is altogether reprehensible either to derive or to try to limit the laws of what we ought to do from what is done.

Now I say: man and generally any rational being exists as an end in himself, not merely as a means to be arbitrarily used by this or that will, but in all his actions, whether they concern himself or other rational beings, must always be regarded at the same time as an end.

...[T]here is no art in being intelligible if one renounces all thoroughness of insight; but also it produces a disgusting medley of compiled observations and half-reasoned principles. Shallow pates enjoy this because it can be used for everyday chat, but the sagacious find in it only confusion, and being unsatisfied and unable to help themselves, they turn away their eyes, while philosophers, who see quite well through this delusion, are little listened to when they call men off for a time from this pretended popularity in order that they might be rightfully popular after they have attained a definite insight.

Our understanding is a faculty of concepts, i.e., a discursive understanding, for which it must of course be contingent what and how different might be the particular that can be given to it in nature and brought under its concepts.

Es ist Gut.

Out of the crooked timber of humanity no straight thing was ever made.

One age cannot bind itself, and thus conspire, to place a succeeding one in a condition whereby it would be impossible for the later age to expand its knowledge (particularly where it is so very important), to rid itself of errors, and generally to increase its enlightenment. That would be a crime against human nature, whose essential destiny lies precisely in such progress; subsequent generations are thus completely justified in dismissing such agreements as unauthorized and criminal. The criterion of everything that can be agreed upon as a law by a people lies in this question: Can a people impose such a law on itself?

...[M]an and generally any rational being exists as an end in himself, not merely as a means to be arbitrarily used by this or that will, but in all his actions, whether they concern himself or other rational beings, must always be regarded at the same time as an end... [R]ational beings... are called persons, because their very nature points them out as ends in themselves, that is, as something which must not be used merely as means, and so far therefore restricts freedom of action (and is an object of respect).

…what things may be in themselves, I know not, and need not know because a thing is never presented to me otherwise than as a phenomena.

Dogmatism is thus the dogmatic procedure of pure reason without previous criticism of its own powers, and in opposing this procedure, we must not be supposed to lend any countenance to that loquacious shallowness which arrogates to itself the name of popularity, nor

Perhaps a revolution can overthrow autocratic despotism and profiteering or power-grabbing oppression, but it can never truly reform a manner of thinking; instead, new prejudices, just like the old ones they replace, will serve as a leash for the great unthinking mass
