IN the first contribution to this series Bertrand Russell viewed with some complacence the scientific society of the future. He admitted that we have not yet organized the world as a whole, but he was hopeful that through science we should eventually do so. I am not concerned, however, at the moment with the question of world organization, important as that is, hut with the inner life of the individual. Bertrand Russell, indeed, reminded us that the things which give positive excellence to human life are in the mind and 4eart, not in the outward mechanism. And it is upon the mind and heart and the relation of science to them that I wish to concentrate.
