In the Introduction of the Tugendlehre, Kant identifies love of human beings as one of the four moral predispositions that make us receptive to the moral law. We claim that this love is neither benevolence nor the aptitude of the inclination to beneficence in general (both are also called love of human beings); rather it is amor complacentiae, which Kant understands as the delight in moral striving for perfection. We also provide a detailed analysis of Kant's almost completely neglected theory (...) of moral predispositions. They are necessary conditions to be aware of the moral law and to be motivated by it.
