Fundamental Principles of The Metaphysic of Morals

For love, as an affection, cannot be commanded, but beneficence for duty`s sake may; even though we are not impelled to it by any inclination- nay, are even repelled by a natural and unconquerable aversion. This is practical love and not pathological- a love which is seated in the will, and not in the propensions of sense- in principles of action and not of tender sympathy; and it is this love alone which can be commanded.
