Wikiquote no longer allows unsourced quotations, and they are in process of being removed from our pages (see Wikiquote:Limits on quotations); but if you can provide a reliable, precise and verifiable source for any quote on this list please move it to Johannes Kepler. --Antiquary 09:39, 21 June 2009 (UTC)
- I demonstrate by means of philosophy that the earth is round, and is inhabited on all sides; that it is insignificantly small, and is borne through the stars.
- Planets move in ellipses with the Sun at one focus.
- So long as the mother, Ignorance, lives, it is not safe for Science, the offspring, to divulge the hidden cause of things
- Truth is the daughter of time, and I feel no shame in being her midwife.
The "shining in the mind of God" quote is by Kepler, but it does not seem to occur in Harmonices Mundi (1618). Rather, I find it is from Dissertatio cum Nuncio Sidereo (1610), edited in KGW [collected works] vol. 4, p. 308, lines 9f, as cited here, verified in the facsimile here, the actual quote reading
- Geometria una et aeterna est in mente Dei refulgens: cuius consortium hominibus tributum inter causas est, cur homo sit imago Dei.
