"Let us now enter our house of safety within which our environment is all contributory to the well being of organic life. By organic life we mean oxygen dependent bodies. Within that triangle on the universal harp are only five of its tones out of its total of 121. Those five tones are carbon, silicon, oxygen, hydrogen and nitrogen. It will probably amaze you to be informed that four of these five elements constitute 98 1/2% of your whole body composition. More amazing still, all five constitute 98 1/2% of the upper few feet of the earth's crust upon which your body is dependent for the food it needs for survival. The basic constituent of animal bodies is carbon while the basic constituent for the fertile life giving earth's crust, is silicon. Silicon is the first stage of death for carbon. It is, therefore, as good for purposes of earth as carbon is for purposes of life." [Atomic Suicide, page 32-33]
