Dear sir/madam I would really appreciate it if you could help me please with finding the name of some books about early concept of the relation of art and morality. what I mean is after Plato and Aristotle to the time of Kant. Or if it is possible, please give me some names of philosophers during that time and then I'll try to find their books. I want to work on the early relation of them and later show how and why they became some how separate in later years. I guess Kant has the most effect on it but I still need more resources.
