This documentary offers a critique of the modern attack on beauty, and on some of the key modern ideologies about what is art and what it means to be an artist. It is provocative and well worth the watch.
I am not sure if I agree with every part of his critique or his tastes. His argument is well considered, certainly, but I find so much in Modern Art beautiful—though much ugliness too (and I can say something similar about art from all periods, though there is more beauty in the past). I love the best of modern architecture, experimental film, and music—much, I am sure, Roger Scruton would not like. I spent a lot of time studying Modern Art years ago at university and I am probably influenced a great deal by that period in my life.
His basic argument seems to be that ugliness is bad and beauty is good, that beauty is linked with something transcendent in humans, and that all this is self-evident, which makes it less an argument more a statement of fact (if you believe it, which I do). Nonetheless, I too advocate for beauty.
