There is nothing mysterious about the construction and operation of a human being, so that it is lazy ignorance to live without knowledge of the machine that carries one through this earthly existence. God abhors lazy beings and He allows them to rot. He is a combination of substances drawn together by Suction and squeezed apart by Pressure. Every movement man makes during his whole life is caused by Suction and Pressure. Man grows up from seed.
Seed is attracted by opposite sex.
Sex is determined by Suction and Pressure. The male is caused by a super-abundance of internal Pressure. The female is caused by a superabundance of internal Suction. When the male seed is drawn into the female seed, a swirling movement is caused in which the combining substances endeavor to reach the center of Suction. The elements thereof are then dissolved and move around and around in currents until they have all become attached to their respective affinities and have taken their proper places in the reorganized formation.
