[Garth]You're really, really missing the point. Not following the scientific method is what defines a person or idea as a crackpot. So its contradictroy to call the scientific method a crackpot idea, even when it was new. You seem to be under the (common) misconception that just being new or not accepted by the majority is what makes an idea crackpottery. Not so at all.

That said, I'm not ready to let Aristotle off the hook.../////////...
Really?
I think here we need to take a more historical perspective of the development of scientific ideas and method.
In its day the Ptolemaic theory was as
scientific a theory as you could have wished for. The fact that it eventually proved to be wrong should no more attract our derision than the fact that most of our present theories will eventually require replacement or modification.
1. It had a mathematical basis - the addition of epicycles to a basic circular motion was a geometric way of constructing a Fourier series to represent the complicated motion of the planets amongst the fixed stars.
2. It was modified over a period of time by the addition of extra epicycles to allow for the resolution of discrepancies between the theory and observation.
3. It was able to predict the future motions of the planets with considerable accuracy, more so, because of these extra additions, than the Copernican theory.
4. These predictions were checked against observations made by huge naked eye observatories.
We may compare this process with the standard cosmological theory,
· GR required a fix that was provided by Inflation
· Inflation required a fix that was provided by Dark Matter
· Dark Matter required a fix that was provided by Dark Energy.
· We now consider the standard LCDM theory robust and “precision cosmology”.
· However, neither Inflation (the Higgs Boson), Dark Matter or Dark Energy have been discovered even after about 30 years of intense effort. An example of modern day epicycles?
The scientific method had developed over a period of time, from the Greeks to the Moslem scholars and through them to the scholastics of medieval Europe. Such 'men' of science as Roger Bacon, Nicolas of Cusa, William of Ockham and Jean Buridan. Copernicus, a century or two later, was a relative Aristotelian compared to them, he preferred to trust the ancient wisdom despite his famous modification of the ancients' (Ptolemy) work.
The Copernican theory, retaining the circular motion of the planets, but now around the Sun, had also to include epicycles. In fact his system had more that the Ptolemaic system! (Copernicus = 48 epicycles, Ptolemy = 40 - although Copernicus exaggerated this number to make his system seem more 'efficient'.) Despite his theory being correct at unseating the Earth from the centre of the solar system, and perhaps because it was not more efficient at explaining the "heavenly revolutions", he was "laughed at and hissed off the stage" -(Galileo's own words about Copernicus' fate, a fate that he did not want to share.)
Nevertheless Galileo had been persuaded about the Copernican system at an earlier age, he was able to take advantage of the newly invented telescope. Galileo was not the first to base his theories on observation, it was just he was able to use a better instrument of observation.
Perhaps his reticence at not wanting to follow Copernicus into derision by delaying publishing his work for twenty years was an indication that he
wasn’t a ‘crackpot’ after all. However his ability to upset most of his contemporaries does not help in that assessment!
