A Quote by Galileo Galilei on authority, competence, doubt, god, judgment, people, senses, and world

And who can doubt that it will lead to the worst disorders when minds created free by God are compelled to submit slavishly to an outside will?  When we are told to deny our senses and subject them to the whim of others?  When people devoid of whatsoever competence are made judges over experts and are granted authority to treat them as they please?  These are the novelties which are apt to bring about the ruin of commonwealths and the subversion of the state.  [On the margin of his own copy of Dialogue on the Great World Systems].

A Quote by Galileo Galilei on ability, extremism, nature, and understanding

It has always seemed to me extreme presumptuousness on the part of those who want to make human ability the measure of what nature can and knows how to do, since, when one comes down to it, there is not one effect in nature, no matter how small, that even the most speculative minds can fully understand.
