Advertencia para idiotas. Pero a todo aquel que sea demasiado estúpido para comprender la ciencia astronómica, o demasiado pusilánime para creer a Copérnico sin que afecte a su fe, le aconsejaría que, una vez renunciado a los estudios astronómicos, y tras haber condenado todos aquellos estudios filosóficos que le plazca, se preocupe de sus asuntos y se vaya a su casa a escarbar su terruño

Astrology and all these mystical things are generally signs of a weak mind; therefore as soon as they are becoming prominent in our minds, we should see a physician, take good food, and rest.

If you study a lot because you are worried that others will think badly of you for being ignorant and you'll feel stupid, this is a serious mistake.

Astronomy to the selfish becomes astrology.

Space, man, have you no respect for science?

If the study to which you apply yourself has a tendency to weaken your affections and to destroy your taste for those simple pleasures in which no alloy can possibly mix, then that study is certainly unlawful, that is to say, not befitting the human mind.

Astrology provides a brilliant proof of the miserable subjectivity of human beings, as a result of which they relate everything to themselves and go from every thought in a straight line immediately back to themselves. It relates the course of the great celestial bodies to the pathetic I, as it also connects the comets in the sky with earthly quarrels and shabby tricks.

I don’t believe in astrology; I’m a Sagittarius and we’re skeptical.

Stars and shadows ain't good to see by.

Computer Science is no more about computers than astronomy is about telescopes

Studying life, eh! Let him take care, studying human life is looking at the stars. If you look too close, there is a dazzle.

Human anatomy is horribly unsuited for outer space. The astroengineers lost sleep over this but not the science fiction writers, who being artists simply didn't mention it.

"As long as you still experience the stars as something "above you", you lack the eye of knowledge."

We have artists with no scientific knowledge and scientists with no
artistic knowledge and both with no spiritual sense of gravity at all,
and the result is not just bad, it is ghastly.
