That matter, i.e. frozen energy, contains an inherent tendency or "nostalgia" to revert to its original state, namely the state of dynamic energy and that this tendency, this nostalgia in matter, is the primary cause of everything we call "evolution" in our world. That certainly is a grandiose idea; so stupendous in fact that I couldn't grasp it all at once. The Brain noticed that immediately and it was very patient in the way it explained: How oxygen and hydrogen are "residuals" of the original dynamic energy flow and how they act as solvents and dissolvents upon the upper crust of our earth, effecting a gradual activation of water, rock and earth. How this activation is being aided and accelerated by another source of dynamic energy: irradiation from the sun. Thus preparing the upper crust of our earth as a "placenta" ready to gestate plant and animal life. How this first "unfreezing" of matter leads on from simple forms to higher, every plant, every animal, every living thing being essentially a "transformer" of static energy into dynamic energy and the higher the stage of evolution, the more so. How as the present culmination of the evolutionary chain stands man; infinitely more complex and higher organized than the microbe, but not different from the monad in the basic purpose of his life: i.e. to be a transformer of energy, a fulfiller of matter's inherent will to revert from the static into the dynamic state. When I asked The Brain's premises for this astonishing concept of our purpose in life, The Brain brought forth such massive proof that I had to close my eyes against the blinding light of revelation. Yes, it is true that Man, the hunter, has been the most predatory animal on earth. It's true that as a tiller of the soil he is a tireless transformer of static soil energy into dynamic plant life energy. It's true that Man, the mechanic, the toolmaker, the tool-user has far surpassed any other animal in the unlocking, the unfreezing of static energy. Think of those billions of mechanical horsepowers in our power plants; the trillions of coal tons and barrels of oil they are burning up; think of the way we have harnessed waterpower, how our weapons are evolving forever in the direction of greater range and speed and disintegrating power. Above all: think of the last great development, atomic energy. And finally it is true that Man as a thinker and as a philosopher has "thought the universe to pieces" for milleniums before he ever achieved the powers to translate such thoughts into reality; powers which seem within reach at this our day and age.... "If this is Man's manifest destiny," I asked The Brain, "to be just as the microbe, a transformer of static energy into dynamic energy; what about Man's metaphysical struggle? What about Man's undying will to rise above himself, Man's reaching out forever toward some Deity?"
