From Schiller's letters on aesthetics

"The misfortune of his brothers, of the whole species, appeals loudly to the heart of the man of feeling; their abasement appeals still louder: enthusiasm is inflamed, and in souls endowed with energy the burning desire aspires impatiently to action and facts. But has this innovator examined himself to see if these disorders of the moral world wound his reason, or if they do not rather wound his self-love? If he does not determine this point at once, he will find it from the impulsiveness with which he pursues a prompt and definite end. A pure, moral motive has for its end the absolute; time does not exist for it, and the future becomes the present to it directly; by a necessary development, it has to issue from the present. To a reason having no limits the direction towards an end becomes confounded with the accomplishment of this end, and to enter on a course is to have finished it."
