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 … - Immanuel Kant

Let us suppose there was a teacher of whom an historical record (or, at least, a widespread belief which is not basically disputable) reports that he was the first to expound publicly a pure and searching religion, comprehensible to the whole world. … Suppose that all he did was done even in the face of a dominant ecclesiastical faith which was onerous and not conducive to moral ends (a faith whose perfunctory worship can serve as a type of all the other faiths, at bottom merely statutory, which were current in the world at the time). Suppose, further, we find that he had made this universal religion of reason the highest and indispensable condition of every religious faith whatsoever … and this without further adding to this faith burdensome new ordinances or wishing to transform acts which he had initiated into peculiar holy practices, required in themselves as being constituent elements of religion. After this description one will not fail to recognize the person who can be referenced, not indeed as the founder of the religion which, free from every dogma, is engraved in all men’s hearts (for it does not have its origin in an arbitrary will), but as the founder of the first true church.

if adversity and hopeless grief have quite taken away the taste for life; if an unfortunate man, strong of soul and more indignant about his fate than despondent or dejected, wishes for death and yet preserves his life without loving it, not from inclination or fear but from duty, then his maxim has moral content.

....Happiness is not an ideal of reason but of imagination, resting solely on empirical grounds, and it is vain to expect that these should define an action by which one could attain the totality of a series of consequences which is really endless.
