Context

“It can be bought, and sold, and bartered away. It can be poisoned, or made perfect. There is a soul in each one of us. I know it." "Do you feel quite sure of that, Dorian?" "Quite sure." "Ah! then it must be an illusion. The things one feels absolutely certain about are never true. That is the fatality of faith, and the lesson of romance. How grave you are! Don't be so serious. What have you or I to do with the superstitions of our age? No: we have given up our belief in the soul.” source
