This passage from a book I'm reading for class has sparked a lot of thought today:
"It is with art as with religion: people think too often that all truth, all perfection, is confined to one sect, to one school, and that beyond it there is nothing but error and imperfection. Nature and the spirit that pervades her is too great a theme to be exhausted by one man or school - a theme to which not even the united schools of all arts and all ages can do justice; it is inexhaustible, infinite. Let us be careful that by disregarding any branch of art, however slight, or by disparaging any style, however uncongenial to our individual taste, we may not lose part of the interpretation of that glorious mystery."
