DO WE TRULY DIE?
Here we spin upon a ball of rock and nickel-steel, upon which a film of water, a few score miles of air, lie like the bloom upon a plum. All about that ball is space unfathomable; all the suns and stars are mere grains of matter scattered through a vastness that is otherwise utterly void. To that thin bloom upon a particle we are confined; if we tunnel down into the earth, presently it is too hot for us to live; if we soar five miles into the air we freeze, the blood runs out of our vessels into our lungs, we die suffocated and choked with blood. . . .
"Out of the litter of muds and gravels that make the soil of the world we have picked some traces of the past of our race and the past of life. In our observatories and laboratories we have gleaned some hints of its future. We have a vision of the opening of the story, but the first pages we cannot read. We discover life, a mere stir amidst the mud, creeping along the littoral of warm and shallow seas in the brief nights and days of a swiftly rotating earth. We follow through vast ages the story of life's extension into the waters, and its invasion of the air and land. Plants creep upon the land and raise themselves by stems towards the sun; a few worms and crustaceans follow, insects appear; and at length come our amphibious ancestors, breathing air by means of a swimming bladder used as a lung. From the first the land animals are patched-up creatures. They eke out the fish ear they inherit by means of an ear drum made out of a gill slit. You can trace scale and fin in bone and limb.
