GALILEO:

Truth is the child of time, not of authority. Our ignorance is infinite, so let us diminish it by a fraction. Why try to be so clever now, when at last we can become a little less stupid? I have had the unbelievable good fortune to lay my hands on a new instrument by means of which one can see one tiny corner of the universe a little clearer. Not much –– but a little. Make use of it!

(The life of Galileo, Bertolt Brecht)

Merecerá um estudo futuro.
