Note 125 — THE MONIST. (continued 2)

Kepler’s scheme is, that all the regular solids, icosahedron, dodecahedron, octohedron, tetrahedron, and cube should be placed one within the other at such distances that spheres could be described between them so as to touch the corners of each respective interior and the planes of each respective exterior solid. He found, by placing the sun in the centre and allowing the planets to move in great circles on the spheres, (making the circle between the icosahedron and dodecahedron equal to the orbit of the earth,) that then the distances between the planets would, upon the whole, agree with astronomical observations.

This theory is as ingenious, as fascinating, and as original as Mr. Peirce’s propositions. It has only one little fault; it does not agree with facts. And Kepler afterwards abandoned his original theory.
