507 Quotes by Immanuel Kant
"For if phenomena are things by themselves, freedom cannot be saved. Nature in that case is the complete and sufficient cause determining every event, and its condition is always contained in that series of phenomena only which, together with their effect, are necessary under the law of nature."
"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."
"For now we see that when we conceive ourselves as free we transfer ourselves into the world of understanding as members of it, and recognise the autonomy of the will with its consequence, morality; whereas, if we conceive ourselves as under obligation we consider ourselves as belonging to the world of sense, and at the same time to the world of understanding."
"But freedom is a mere Idea, the objective reality of which can in no wise be shown according to the laws of nature, and consequently not in any possible experience; and for this reason it can never be comprehended or understood, because we cannot support it by any sort of example or analogy."
"There are such manifold forms of nature; there are many modifications of the general transcendental concepts of nature that are left undetermined by the laws furnished by pure intellect a priori because these laws only concern the general possibility of nature as an object of the senses."
"Only by what a man does heedless of enjoyment, in complete freedom and independently of what he can produce passively from the hand of nature, does he give absolute worth to his existence, as the real existence of a person. Happiness, with all its plethora of pleasures, is far from being an unconditioned good."
"No one may force anyone to be happy according to his manner of imagining the well-being of other men; instead, everyone may seek his happiness in the way that seems good to him as long as he does not infringe on the freedom of others to pursue a similar purpose, when such freedom may coexist with the freedom of every other man according to a possible and general law."
"We have no reason for assuming the form of such a thing to be still partly dependent on blind mechanism, for with such confusion of heterogeneous principles every reliable rule for estimating things would disappear."
"...Freedom of the will is of a wholly unique nature in that an incentive can determine the will to an action only so far as the individual has incorporated it into his maxim (has made it the general rule in accordance with which he will conduct himself); only thus can an incentive, whatever it may be, co-exist with the absolute spontaneity of the will (i.e., freedom)."
"He who would know the world must first manufacture it."
