Speaking of lines and shapes, forms and colors... by coincidence, I found the following quote in the book I am reading, Landscape into Art, by Kenneth Clark, where he cites Socrates:
"I will try to speak of the beauty of shapes... straight lines and curves and the shapes made of them... They are not beautiful for any particular reason or purpose, as other things are, but are eternally, and by their very nature, beautiful, and give a pleasure of their own quite free from the itch of desire: and in this way colors can give a similar pleasure..."
I've always suspected I have something in common with Socrates, now I know exactly what
