Seen from the point of view of metaphysics, why is the power of indifference greater than the power of interest? Because although motive has a power, yet at the same time motive limits power. Man is endowed at birth with much greater power than he ever imagines, and it is motive that limits this power: any motive and every motive; yet it is motive that gives man the power to accomplish things. If there were no motive there would be no power. But when one compares the original power of man with the power of motive, one will find it is just like the difference between the ocean and a drop. The motive reduces the power to a drop. Without a motive the power of the soul is like an ocean; but at the same time that ocean-like power cannot be used without a motive, while as soon as one wants to use it for a purpose it becomes less.
