John Ruskin,
A Joy For Ever (and Its Price in the Market…
“ So that by every farthing you give for a picture beyond its fair price—that is to say, the price which will pay the painter for his time—you are not only cheating yourself and buying vanity, but you are stimulating the vanity of others; paying, literally, for the cultivation of pride. You may consider every pound that you spend above the just price of a work of art, as an investment in a cargo of mental quick-lime or guano, which, being laid on the fields of human nature, is to grow a harvest of pride. ”
