So, Fabricius, I already have this: that the most true path of the planet [Mars] is an ellipse, which Dรผrer also calls an oval, or certainly so close to an ellipse that the difference is insensible.
Johannes KeplerSo long as the mother, Ignorance, lives, it is not safe for Science the offspring, to divulge the hidden causes of things.
Johannes KeplerI am much occupied with the investigation of the physical causes [of motions in the Solar System]. My aim in this is to show that the celestial machine is to be likened not to a divine organism but rather to a clockwork ... insofar as nearly all the manifold movements are carried out by means of a single, quite simple magnetic force. This physical conception is to be presented through calculation and geometry.
Johannes KeplerThe wisdom of the Lord is infinite as are also His glory and His power. Ye heavens, sing His praises; sun, moon, and planets, glorify Him in your ineffable language! Praise Him, celestial harmonies, and all ye who can comprehend them! And thou, my soul, praise thy Creator! It is by Him and in Him that all exist.
Johannes Kepler
