“Action is man's free will right, but the reaction is nature's.”

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.

Context: To every action there is always opposed an equal reaction; or, the mutual actions of two bodies upon each other are always equal, and directed to contrary parts.

Context: Man is naturally more disposed to beneficent than selfish actions. This we learn even from the history of savages. The domestic virtues have something in them so inviting and genial, and the public virtues of the citizen something so grand and inspiring, that even he who is barely uncorrupted, is seldom able to resist their charm.
