A most unfailing experience... of the excitement of sublunary (that is, human) natures by the conjunctions and aspects of the planets has instructed and compelled my unwilling belief.
Interpretation
The quote suggests that human nature is profoundly influenced by celestial events, even if one is reluctant to accept this idea.
In this quote, Johannes Kepler expresses his belief in the impact of planetary positions on human emotions and behaviors. Despite his initial skepticism, he acknowledges the compelling evidence that connects sublunary, or earthly, experiences to astronomical phenomena, highlighting the intricate relationship between humanity and the cosmos.
In practice
During a discussion on astrology's impact on personality, this quote could illustrate the historical perspectives on celestial influences.
...Those laws are within the grasp of the human mind. God wanted us to recognize them by creating us after his own image so that we could share in his own thoughts... and if piety allow us to say so, our understanding is in this respect of the same kind as the divine, at least as far as we are able to grasp something of it in our mortal life.
We find, therefore, under this orderly arrangement, a wonderful symmetry in the universe, and a definite relation of harmony in the motion and magnitude of the orbs, of a kind that is not possible to obtain in any other way.
I am stealing the golden vessels of the Egyptians to build a tabernacle to my God from them, far far away from the boundaries of Egypt. If you forgive me, I shall rejoice; if you are enraged with me, I shall bear it. See, I cast the die, and I write the book. Whether it is to be read by the people of the present or of the future makes no difference: let it await its reader for a hundred years, if God himself has stood ready for six thousand years for one to study him.
Eyesight should learn from reason.
I measured the skies, now the shadows I measure, Sky-bound was the mind, earth-bound the body rests. [Kepler's epitaph]
It may be well to wait a century for a reader, as God has waited six thousand years for an observer.
I don't know much about climate change. But I'm pretty sure we better figure out what to do to lessen its impact - at least its health impact - and that's not going to happen unless you have a lot of young talent interested in these topics.
Round about the accredited and orderly facts of every science there ever floats a sort of dust-cloud of exceptional observations, of occurrences minute and irregular and seldom met with, which it always proves more easy to ignore than to attend to... Anyone will renovate his science who will steadily look after the irregular phenomena, and when science is renewed, its new formulas often have more of the voice of the exceptions in them than of what were supposed to be the rules.
Science is feasible when the variables are few and can be enumerated; when their combinations are distinct and clear. We are tending toward the condition of science and aspiring to do it. The artist works out his own formulas; the interest of science lies in the art of making science.
My Design in this Book is not to explain the Properties of Light by Hypotheses, but to propose and prove them by Reason and Experiments: In order to which, I shall premise the following Definitions and Axioms.
Dreaming in public is an important part of our job description, as science writers, but there are bad dreams as well as good dreams. We're dreamers, you see, but we're also realists, of a sort.
You know what they call alternative medicine that's been proved to work? - Medicine.
