Adam Smith,
The Theory of Moral Sentiments…
“ I cannot, however, be induced to believe that our sense even of external beauty is founded altogether on custom. The utility of any form, its fitness for the useful purposes for which it was intended, evidently recommends it, and renders it agreeable to us, independent of custom. Certain colours are more agreeable than others, and give more delight to the eye the first time it ever beholds them. A smooth surface is more agreeable than a rough one. Variety is more pleasing than a tedious undiversified uniformity. ”
