Human reason goes forth inexorably to such questions as cannot be answered by any experiential use of reason or principles based on it. - Immanuel Kant

عندما يكون شىء ما متطرفاً أو مفرطاً فى حضوره و قوته فإنه سيكون، بالنسبة للخيال، هاوية سحيقة، يخاف الخيال أن يفقد ذاته فيها

"A good will is good not because of what it effects, or accomplishes, not because of its fitness to attain some intended end, but good just by its willing, i.e. in itself; and, considered by itself, it is to be esteemed beyond compare much higher than anything that could ever be brought about by it in favor of some inclinations, and indeed, if you will, the sum of all inclinations. Even if by some particular disfavor of fate, or by the scanty endowment of a stepmotherly nature, this will should entirely lack the capacity to carry through its purpose; if despite its greatest striving it should still accomplish nothing, and only the good will were to remain (not of course, as a mere wish, but as the summoning of all means that are within our control); then, like a jewel, it would still shine by itself, as something that has full worth in itself".

Without man and his potential for moral progress, the whole of reality would be a mere wilderness, a thing in vain, and have no final purpose.
