What I must know is whether you are indeed one of those creatures in the lowest grade of mentality and even of charm, one of those contemptible creatures who are incapable of foregoing a pleasure. And if you are such, how could anyone love you, for you are not even a person, a clearly defined entity, imperfect but at least perfectible. You are a formless water that will trickle down any slope that offers itself, a fish devoid of memory, incapable of thought, which all its life long in its aquarium will continue to dash itself a hundred times a day against a wall of glass, always mistaking it for water. Do you realise that your answer will have the effect — I won't say of making me cease loving you immediately, of course, but of making you less attractive in my eyes when I realise that you are not a person, that you are beneath everything in the world and incapable of raising yourself one inch higher?
Proust, Swanns Way, "Swann in Love"
