I measured the skies, now the shadows I measure, Sky-bound was the mind, earth-bound the body rests. [Kepler's epitaph]
Johannes KeplerSo long as the mother, Ignorance, lives, it is not safe for Science the offspring, to divulge the hidden causes of things.
Johannes KeplerGeometry existed before the creation. It is co-eternal with the mind of God...Geometry provided God with a model for the Creation.
Johannes KeplerI myself, a professional mathematician, on re-reading my own work find it strains my mental powers to recall to mind from the figures the meanings of the demonstrations, meanings which I myself originally put into the figures and the text from my mind. But when I attempt to remedy the obscurity of the material by putting in extra words, I see myself falling into the opposite fault of becoming chatty in something mathematical.
Johannes KeplerGeometry, which before the origin of things was coeternal with the divine mind and is God himself (for what could there be in God which would not be God himself?), supplied God with patterns for the creation of the world, and passed over to Man along with the image of God; and was not in fact taken in through the eyes.
