A classical work doesn't ever have to be understood entirely. But those who are educated and who are still educating themselves must desire to learn more and more from it.
The difference between religion and morality lies simply in the classical division of things into the divine and the human, if one only interprets this correctly.
Religion must completely encircle the spirit of ethical man like his element, and this luminous chaos of divine thoughts and feelings is called enthusiasm.
Kant introduced the concept of the negative into philosophy. Would it not also be worthwhile to try to introduce the concept of the positive into philosophy?
Religion can emerge in all forms of feeling: here wild anger, there the sweetest pain; here consuming hatred, there the childlike smile of serene humility.

Duty is for Kant the One and All. Out of the duty of gratitude, he claims, one has to defend and esteem the ancients; and only out of duty has he become a great man.
