“It's a curious thing that the mental life seems to flourish with its roots in spite, ineffable and fathomless spite. Always has been so! Look at Socrates, in Plato, and his bunch round him! The sheer spite of it all, just sheer joy in pulling somebody else to bits...Protagoras, or whoever it was! And Alcibiades, and all the other little disciple dogs joining in the fray! I must say it makes one prefer Buddha, quietly sitting under a bo-tree, or Jesus, telling his disciples little Sunday stories, peacefully, and without any mental fireworks. No, there's something wrong with the mental life, radically. It's rooted in spite and envy, envy and spite. Ye shall know the tree by its fruit.”
