Life is not governed by will or intention. Life is a question of nerves, and fibres, and slowly built-up cells in which thought hides itself and passion has its dreams. You may fancy yourself safe, and think yourself strong. But a chance tone of colour in a room or a morning sky, a particular perfume that you had once loved and that brings sublte memories with it, a line from a piece of music that you had ceased to play--I tell you Dorian, that it is on things like these that our lives depend.
