Conscious intellect, memory and will-power are necessary to generate, guide and control the force and motion employed in the construction of a compound physical structure, whatever its form or size may be. Each spermatozoön is composed of myriads of atoms. The atoms of each are chemically combined and mechanically arranged in the same manner that those in every other are, all spermatozoä being identical in chemical composition, mechanical arrangement, form and size. The same is true of each ovum and fertilized ovum, and of the atoms in them, respectively, _vice versa_. So each embryo is composed of myriads of cells, the cells in each having identically the same chemical composition and mechanical arrangement that those in every other embryo of the same age and sex have; all embryos of the same age and sex having substantially the same chemical combinations and mechanical arrangements of their cells, organs and parts. It follows that each human spermatozoön, ovum, fertilized ovum and embryo, of the same age and sex is constructed according to certain prescribed “plans and specifications.” We are, therefore, compelled to assume that the force and motion necessary to construct the spermatozoön, ovum, fertilized ovum and embryo are generated, guided and controlled by a Being with full knowledge of the “plans and specifications,” of the chemical elements, their affinities and combinations, of mechanical arrangements, etc. The Architect must know the “plans and specifications;” must be able to compare the work of construction with them, as the work progresses; must have memory to bear in mind and recall the plans and specifications; and must have will-power to begin and continue the work until the “structure” is completed. So He must see that each organ and part attains its proper form and size at the right time; that each organ and part is properly proportioned to and correlated with, every other on each day of its growth. In other words: He must see that the forces at work, and the motions produced in each organ and part of the embryo body are proportioned to and in harmony with the forces at work and the motions produced in every other; that the development and growth of each organ and part keeps pace with those of every other. This knowledge, power and creative force belongs only to the Creator. Sec. 13. Spermatozoön A spermatozoön is a microscopic body contained in the semen, to which the seminal fluid owes its vitality; and which is the immediate means of impregnating or fertilizing the ovum of the female; a spermatic cell or filament; a spermatozoid.
