“With these dramatic words, Kant alludes to the two great problems and accomplishments of his philosophical career. On the one hand, he wants to know how we who as creatures are a mere part of nature can discover how all of nature … does and even must work. On the other hand, he wants to display the unconditional value that we have as rational rather than merely natural beings, … and that we are always free to act in accordance with and indeed for the sake of this principle, thus free to realize the unconditional value for which we unlike anything else in nature have the potential.”
