Marcel Proust said this quote
“ Lying is essential to humanity. It plays as large a part perhaps as the quest for pleasure, and is moreover governed by that quest. One lies in order to protect one's pleasure, or one's honour if the disclosure of one's pleasure runs counter to one's honour. One lies all one's life long, even, especially, perhaps only, to those who love one. For they alone make us fear for our pleasure and desire their esteem. ”
