Galileo was a very smart person capable of making many inventions like the telescope but to pay for living accommodations he became a professor at the university of Pisa.
He is most know for being a very smart scientist, inventor and a great professor.
"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."
This is an example of humanism because the church told him not to release his findings and he did anyway and I feel this quote is almost a response to what the church told him to do.
The telescope has been modified and made better so we can observe even more things in space further pushing science and our understanding of our universe thanks to Galileo.
