"By a similar process--which I may liken to that of putting off an evil day which some time must be endured--the atoms group themselves into molecules. In their turn the molecules go forth to war, capturing or being captured; the vibrations of the slaves always being forced to synchronise with those of their conquerors. The nucleus of the gas of a primal metal is now complete, and the foundation of a solar system--paltry molecule of the Universe as it is--is laid. Thereafter, the rest is easily followed. It is described in your school books, and must not occupy me now. "But one word I will interpolate which may serve to explain a curious and interesting human belief. You are aware of how, in times past, men of absolutely no scientific insight held firmly to the idea that an elixir of life and a philosopher's stone might be discovered, and that these two objects were nearly always pursued contemporaneously. That is to my mind an extraordinary example of the force of atomic consciousness. The idea itself was absolutely correct; but the men who followed it had slight knowledge of its unity, and none whatever of its proper pursuit. They would have worked on their special lines to eternity before advancing a single step toward their object. And this because they did not know what life was, and death was, and what the metals ultimately signified which they, blind fools, so unsuccessfully tried to transmute. But we know more than they. We have climbed no doubt in the footholds they have carved, and we have gained the summit they only saw in the mirage of hope. For we know that there is no life, no death, no metals, no matter, no emotions, no thoughts; but that all that we call by these names is only the ether in various conditions. Life! I could live as long as this earth will submit to human existence if I had studied that paltry problem. Metals! The ship in which you sail was bought with gold manufactured in my crucibles.
