Here is a great video by Philosopher Roger Scruton. Here is the description from the website:
Philosopher Roger Scruton presents a provocative essay on the importance of beauty in the arts and in our lives.
In the 20th century, Scruton argues, art, architecture and music turned their backs on beauty, making a cult of ugliness and leading us into a spiritual desert.
Using the thoughts of philosophers from Plato to Kant, and by talking to artists Michael Craig-Martin and Alexander Stoddart, Scruton analyses where art went wrong and presents his own impassioned case for restoring beauty to its traditional position at the center of our civilization.
