Patented in 1914, Socrates Scholfield’s “illustrative educational device” uses two spiral springs to demonstrate the existence of God. Or to demonstrate the tension between good and evil. Or to demonstrate the consciousness of an animal organism. Actually I’m not sure what it demonstrates, and I’ve read the five-page abstract twice.
This schematic device … provides an educational emblem of the conscious relation that must exist between the co-extensive dispensing mediums for beneficence and maleficence, in the terrestrial factory; and it clearly indicates that the attribute of maleficence, which is ascribed to the realm of the adverse medium, may, under certain changed conditions, be made subject to decrease, and to a change in its relative action; while the attribute of beneficence, which pertains to the realm of the controlling supreme governor, is unconditioned, unchangeable and everlasting.
Here’s the whole thing if you want to try it out. Be careful, I guess.
