Die Neugier steht immer an erster Stelle eines Problems, das gelöst werden will. - Galileo Galilei

My dear Kepler, I wish that we might laugh at the stupidity of the human herd. What do you have to say about the principal philosophers of this academy who are filled with the stubbornness of an asp and do not want to look at either the planets, the moon or the telescope, even though I have freely and deliberately offered them the opportunity a thousand times? Truly, just as the asp stops its ears, so do these philosophers shut their eyes to the light of truth.

Не се чувствам длъжен да вярвам, че Господ, който ни е надарил с чувства и разум, е възнамерявал да забравим за тях.

I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forgo their use.
