“But Galileo”

Galileo was right, therefore contrarians are right.


[AARON] Galileo and Bruno denied the scientific con[s]ensus. Just like climate sceptics. Therefore they are wrong.

[JON] There was a mountain of evidence for Newton, then came Einstein. And in a different way, there was “mountain of evidence” that the sun revolves around the earth, then came Galileo.

[JUAN PEDRO] Galileo was perhaps the first known conspiracy theorist as well. Fighting the climate religion with facts and science is the same today.

[STEVE SAILER] And yet, it moves.

Objections and Replies

(Astronomy) Galileo established astronomy as
Reply. He rooted for Copernicus’ model that was 100 years old, and Kepler. He did not establish scientific journalism either. Perhaps scientific vulgarization?

(Devout) Galileo was a good, devout Catholic
Reply. Galileo was great in many ways, but not in his religulous fervor.

(Disinterested) Galileo pursued truth for its own sake
Reply. According to TonyC, Mario Biagioli shows how Galileo exploited his scientific discoveries to climb the social ladder.

(Dogma) The Church was never questioned
Reply. There were lots of disputes within the Church, starting very early on.

(Experiment) Galileo was the first empiricist
Reply. Aristotle collected many specimens. Aristotelians too. Empirical work is arguably as old as men. Besides, Galileo faked or elided data as he saw fit.

(Father) Galileo is the father of modern science
Reply. Galileo was more of a Carl Sagan mixed with a Nassim Taleb. He attacked scholastic authorities more than he engaged with real scientists. Further, the debates were won with rhetorical bombast.

(Heresy) Galileo was charged of heresy
Reply. You mean suspicion of vehement heresy, and that was after being warned in 1613 and interrogated in 1633 after breaking his word. Galileo has never been excommunicated.

(Math) Galileo mathematized nature
Reply. That makes Archimedes sad. Galileo was no great mathematician: he miscalculated the area of a cycloid, and needed to rely on paper models.

(Prison) Galileo was imprisoned (in a dongeon)
Reply. He was under house arrest, in a villa outside Florence near his daughters. He often received guests.

(Right) Galileo was right
Reply. Not about the Moon (he thought she had an atmosphere), Venus, tides, comets, extrusion by whirling, the orbital velocity of planets, the path of a falling body, etc.

(Science) Galileo invented the word “Science”—
Reply. Not really.

(Telescope) Galileo invented the telescope and
Reply. Thomas Harriot did. He built one, published a pamphlet in 10 days, and got sponsors using his technological edge.


{Cf.} I will not discuss other heroes. See #ButMyGuru for the general point.

{History} If history makes you feel bad, that’s fine Ted.

{Parallax} Stellar parallax has been observed only in 1838 by Friedrich Bessel. Without that result the heliocentric model remains problematic.

{We Are Science} There are no heroes. Science is a collective endeavour.
