This is one I wrote (when I was freelance) for a prologue of a friends book[oh, and this is copyrighted by publishing laws]:
A Warning and A Hope
"We manipulated the atom, that which breathes life into the abyss, and shaped it to every contour of our ill wills. In hazes and clouds we scattered cities to the winds, and brothers to the flame. We brought fission to the dormant, and with it wrought pure destruction. While crumbled spires glowed green under a dusty moon, we arrogantly sat upon cushioned thrones and declared victory while sipping from our golden chalices and eating from our silver plates. We did not, in truth, claim victory over others, but over nature itself. We terrifingly create mechanized versions in the image of what we deem the greatest design on Earth, our design, God's design. We now hold the power of God in our hands: the power to both create and destroy life. We are as harvesters with red-lined sickles, forever hacking away at that which seemingly binds us to our foolishness. With every bit of technology clamoring to lay siege to its predecessor, we climb the black stone steps of the Tower of Babel. With every panting breath and roughened step, we pitifully inch up the ladder which we created in an attempt to see the face of the Divine. We crawl down the Left Hand Path forevermore in our attempts to find out if our mud-caked feet and our grey tinted eyes were worth it. We wish to know that our pathetic scramble for the End Days wasn't all for naught, that the tears of our children and the rivers of lead intwined with blood were not spent in vain. We are our own folly, our own irony by definition; in our quest for the betterment of Gaia and humankind alike, we broke every Seal and every commandment with our serpent words and our secret jihads. Let us as brothers and sisters pray we never reach the pinnacle of the Tower, that we never must reap what we sow. As undeserving as we are, let us cling to this Earth and spread our venemous veins to others; let us conquer this land and its scattered stars alike. Never let go of our pride, my branched out cousins who sprang forth from the same loins as I. Filthy as we are, let us spread our word to the heavens to show that God's bastard children have risen to his divine seat and laughed in his face of hypocrisy.
Long live man, for his intelligence and his ingenuity are both his undoing and his ascension."
