Galileo on Astronomical Realism and the Pragmatic Compromise
... Galileo’s approach also differed from others in that he did not simply hope to accommodate already existing observations, but to actively seek out new phenomena in order to revise and improve physics. As he says in the Letters on Sunspots, he hoped to “tune… this great discordant organ of our philos ...
