All of them were still theological thinkers though,

the index was abandoned in 1962. Newton was an Aryan heretic.
The statement of Laplace is a part of the story when Newton called in
God to preserve the stability of the Sun system. Two quotes from

apart but oscillated with a very large period. ‘I do not need this

Napoleon was not asking about the stability of the solar system. He had
not even read Laplace's book.
“But this was not yet the end of matter. … A precise calculation would
have given infinities. … But this meant that Newton’s theory gave
correct results only when used in an ad hoc way.”
Where has Feyerbrand written this? Is he claiming that the solar system
cannot be stable within Newton's theory? Does he think GR is needed
This is a quote from Tyranny of Science
He is really saying that using Laplaces method of series, taking the limit of the series
would have given infinities. He recognizes that Poincare showed how the solar system is
stable within Newtonian physics. So it is not the case "that Newton's theory gave correct
results only when used in an ad hoc way."
Feyerbrand claims that the creation of knowledge does not happen according to so called
From Wikipedia "The Oxford English Dictionary says that scientific method is: "a method
or procedure that has characterized natural science since the 17th century, consisting
in systematic observation, measurement, and experiment, and the formulation, testing,
and modification of hypotheses."
As I read him, Feyerbrand does not deny this general outline, he just notes that
scientists do not always abandon a theory because of one or a few contrary observations.
They know that observations and calculations have been in error.
"Nobody believes a theory, except the guy who thought of it.
Everybody believes an experiment, except the guy who did it."
--- Leon Lederman on physics
Feyerbrand does not care by himself, whether Solar system is stable or not, this is not
his business. He justs comments on how the development of science has happened according
to historical facts.
