I’m puzzling over your post and do not quite understand what it is getting at, especially the final sentence. What intrumentalist hypothesis was declared formal heresy, and what was Galileo’s heliocentric empiricism?
What was the TRUTH that Galileo’s case was about preserving? I don’t follow.
That’s something else I’ll have to study, Descartes hypothesis ploy. Or you can help us out.
Ok Mac, I will explain. I was using your ideas, those I underlined, and turning them against you. You suggested:
** That may be what the pope and others around thought. So, Galileo, why not discuss Copernicus hypothetically? Suppositionally? That’s what they wanted him to do. It’s possible they were confused about Galileo insisting his notions to be literally true. **
You suggested that the popes, cardinals and theologians of the Holy Office in 1616 and 1633 were ‘instrumentalists’, that is, did not hold the subject matter of the passages of Scripture under consideration as a truth but only as an instrument of calculation. Here you are on this:
'Whether or not the theory was literally true of objective reality was beside the point.'
You also said that Galileo was the first ‘realist’, the one who sought the truth or reality.
Now let us put these two positions into context in 1616 when considering my last sentence:
'Now that is a novel invention, the Church defining and declaring an instrumentalist hypothesis formal heresy to protect it from Galileo’s heliocentric empiricism.'
It amounts to this: The Church declared and defined a contrary view to what they did not consider a reality, a truth, as formal heresy. Yes, it suggests they declared an abstract in their minds formal heresy. That is like saying they defined and declared algebra as formal heresy. But you go further, You suggest Galileo was the only one dealing in reality, that only his heliocentrism was put forward as a truth in this affair.
Your last question Mac holds the key to the Galileo case, a key you will not find ANYWHERE and certainly not in any suggested website. It also has a bearing on your own hypothesis.
I call it the hypothesis ploy, begun by Descartes immediately after Galileo’s trial, It amounts to this. Not wanting to accept the Church’s ruling on the correct interpretation of the cosmic order as divinely revealed, they needed to get the word out that the 1616 decree and 1633 decision were not really final, so they said the Church allowed heliocentricism to be held as a hypothesis, a hypothesis that meant awaiting scientific verification. With the trial documents not on public view, the ploy took hold. In fact the Church’s ‘hypothesis’ had been clarified in 1615 by Cardinal Bellarmine when he made reference to Copernicus’s hypothesis.
So, what was Copernicus’s hypothesis. Well in a preface to his book De Revolutionibus, it spelled out the type of hypothesis allowed by the Church.
This artist is markedly outstanding in both these respects for it is not necessary that these hypotheses should be true, or even possible; but it is enough if they provide a calculus which fits the observations…And if it constructs and thinks up causes - and it has certainly thought up a good many - nevertheless it does not think them up in order to persuade anyone of their truth but only in order that they provide a correct basis for calculation…Maybe the philosopher demands probability instead; but neither of them will grasp anything certain or hand it on, unless it has been divinely revealed to him.’
Yes Mac, your ‘instrumentalist’ hypothesis is the one the Church allowed, not as a truth, nor even a theory awaiting proof or not. Confident in the truth of Scripture and the Interpretation of the Fathers. NOW THAT’S CATHOLIC FAITH.
When Newton’s and Bradley’s proofs were accepted by eighteenth century Churchmen as true, thus supposedly falsifying the 1616 decree and the Interpretation of the Fathers, the need for an OUT became an obsession. So they brought back the hypothesis until proven ploy.
The showdown came during the considerations of the 1616 decree by the Holy office in 1820. Thanks to the scholar Finocchio in his
Retrying Galileo we know the actual details of the arguments. Here is the crucial argument, the hypothesis ‘lie’ used inside the Church to defy the 1616 decree as immutable. Anfossi defends the 1616 decree as immutable.
Anfossi: ‘Does he [Canon Settele] want to be authorised to teach principles that are repugnant to Sacred Scripture and its true and Catholic interpretation, which is not to be tolerated at all in a Christian man and especially in a cannon, and to teach them not as a hypothesis (for which there would be no difficulty) but as thesis?’
Olivieri: ‘Now this proposition seems to me to be infected with intolerable absurdity… The Most Rev. Grandi has said it very well: “If this system had been judged erroneous or heretical, the Church would never have allowed it to be maintained even as a hypothesis; the reason is that otherwise those who studied it would be placed at risk of sinning against the faith, in case they judged the system to be manifestly demonstrated.” ’
The lie won out and the infamous U-turn was completed in 1835. Today the same hypothesis ploy is used by modern writers on the Galileo case to cheat the Church out of its 1616 decree.
