“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.”

“But although all our knowledge begins with experience, it does not follow that it arises from experience.”

“It is of great consequence to have previously determined the concept that one wants to elucidate through observation before questioning experience about it; for one finds in experience what one needs only if one knows in advance what to look for.”

“Space and time are the framework within which the mind is constrained to construct its experience of reality.”

“A good will is good not because of what it effects, or accomplishes, not because of its fitness to attain some intended end, but good just by its willing, i.e. in itself; and, considered by itself, it is to be esteemed beyond compare much higher than anything that could ever be brought about by it in favor of some inclinations, and indeed, if you will, the sum of all inclinations. Even if by some particular disfavor of fate, or by the scanty endowment of a stepmotherly nature, this will should entirely lack the capacity to carry through its purpose; if despite its greatest striving it should still accomplish nothing, and only the good will were to remain (not of course, as a mere wish, but as the summoning of all means that are within our control); then, like a jewel, it would still shine by itself, as something that has full worth in itself".”

“...new prejudices will serve as well as old ones to harness the great unthinking masses.For this enlightenment, however, nothing is required but freedom, and indeed the most harmless among all the things to which this term can properly be applied. It is the freedom to make public use of one's reason at every point. But I hear on all sides, 'Do not argue!' The Officer says: 'Do not argue but drill!' The tax collector: 'Do not argue but pay!' The cleric: 'Do not argue but believe!' Only one prince in the world says, 'Argue as much as you will, and about what you will, but obey!' Everywhere there is restriction on freedom.”

“[Standing armies] constantly threaten other nations with war by giving the appearance that they are prepared for it, which goads nations into competing with one another in the number of men under arms, and this practice knows no bounds. And since the costs related to maintaining peace will in this way finally become greater than those of a short war, standing armies are the cause of wars of aggression that are intended to end burdensome expenditures. Moreover, paying men to kill or be killed appears to use them as mere machines and tools in the hands of another (the nation), which is inconsistent with the rights of humanity.”
