Scented Quote of the Day, from Immanuel Kant:

"Olfaction is a kind of taste experienced at a distance. Others are forced, willy-nilly, to participate in this pleasure. And this is why, being in contradiction with freedom, olfaction is less social than taste, where among many dishes or bottles a guest can choose one that he likes without others being forced to share the pleasure of it. "
