What are we, the inhabitants of this globe, least among the many that people infinite space? Our minds embrace infinity; the visible mechanism of our being is subject to merest accident. Day by day we are forced to believe this. He whom a scratch has disorganised, he who disappears from apparent life under the influence of the hostile agency at work around us, had the same powers as I; I also am subject to the same laws. In the face of all this we call ourselves lords of the creation, wielders of the elements, masters of life and death, and we allege in excuse of this arrogance, that though the individual is destroyed, man continues forever."
