“Chacun recèle en lui une forêt vierge, une étendue de neige où nul oiseau n'a laissé son empreinte.”De la maladie
En anglais : "We do not know our own souls, let alone the souls of others. Human beings do not go hand in hand the whole stretch of the way. There is a virgin forest in each; a snowfield where even the print of birds' feet is unknown. Here we go alone, and like it better so. Always to have sympathy, always to be accompanied, always to be understood would be intolerable." ( On Being Ill )
