It was on this occasion that Kepler submitted his celebrated remonstrance: "Eighty years have elapsed during which the doctrines of Copernicus regarding the movement of the earth and the immobility of the sun have been promulgated without hinderance, because it was deemed allowable to dispute concerning natural things, and to elucidate the works of God, and now that new testimony is discovered in proof of the truth of those doctrines--testimony which was not known to the spiritual judges--ye would prohibit the promulgation of the true system of the structure of the universe." None of Kepler's contemporaries believed the law of the areas, nor was it accepted until the publication of the "Principia" of Newton.

In fact, no one in those times understood the philosophical meaning of Kepler's laws.

He himself did not foresee what they must inevitably lead to.

His mistakes showed how far he was from perceiving their result.

Thus he thought that each planet is the seat of an intelligent principle, and that there is a relation between the magnitudes of the orbits of the five principal planets and the five regular solids of geometry.
