“The nature of a Divine Being is seen more clearly in deeds which are loving than in deeds which are marvelous. He does not need miracle to make us love him or to prove that he is more than man. The unanswerable argument for his religion is that wherever he is sincerely followed men’s lives are changed.”

The Educational Theory of Immanuel Kant (1904)
Context: Man has his own inclinations and a natural will which, in his actions, by means of his free choice, he follows and directs. There can be nothing more dreadful than that the actions of one man should be subject to the will of another; hence no abhorrence can be more natural than that which a man has for slavery. And it is for this reason that a child cries and becomes embittered when he must do what others wish, when no one has taken the trouble to make it agreeable to him. He wants to be a man soon, so that he can do as he himself likes.

Part III : Selection on Education from Kant's other Writings, Ch. I Pedagogical Fragments, # 62

Einen Menschen verstehen heißt also: auch er sein. Der geniale Mensch aber offenbarte sich an jenen Beispielen eben als der Mensch, welcher ungleich mehr Wesen versteht als der mittelmäßige. Goethe soll von sich gesagt haben, es gebe kein Laster und kein Verbrechen, zu dem er nicht die Anlage in sich verspürt, das er nicht in irgend einem Zeitpunkte seines Lebens vollauf verstanden habe. Der geniale Mensch ist also komplizierter, zusammengesetzter, reicher; und ein Mensch ist um so genialer zu nennen, je mehr Menschen er in sich vereinigt, und zwar, wie hinzugefügt werden muß, je lebendiger, mit je größerer Intensität er die anderen Menschen in sich hat.

Context: War is an ugly thing, but not the ugliest of things: the decayed and degraded state of moral and patriotic feeling which thinks that nothing is worth a war, is much worse. When a people are used as mere human instruments for firing cannon or thrusting bayonets, in the service and for the selfish purposes of a master, such war degrades a people. A war to protect other human beings against tyrannical injustice; a war to give victory to their own ideas of right and good, and which is their own war, carried on for an honest purpose by their free choice, — is often the means of their regeneration. A man who has nothing which he is willing to fight for, nothing which he cares more about than he does about his personal safety, is a miserable creature who has no chance of being free, unless made and kept so by the exertions of better men than himself. As long as justice and injustice have not terminated their ever-renewing fight for ascendancy in the affairs of mankind, human beings must be willing, when need is, to do battle for the one against the other.

1950s, Give Us the Ballot (1957)
Context: Now, I’m not talking about a sentimental, shallow kind of love. I’m not talking about eros, which is a sort of aesthetic, romantic love. I’m not even talking about philia, which is a sort of intimate affection between personal friends. But I'm talking about agape. I'm talking about the love of God in the hearts of men. I’m talking about a type of love which will cause you to love the person who does the evil deed while hating the deed that the person does. We've got to love.
