A very good on; …so typical vis-à-vis Pythagorus and what is called “objective idealism”.
It reminds me also the work of Emil Post, which anticipated everything from Gödel to the Mechanist Immaterialism, before taking this one back after a discussion with Turing, who was materialist/naturalist.
In fact, I have often think that there should be an error in my proof because, as it is technically simple, I could not figure out why Einstein and Gödel did not found it. Eventually, I understood why Einstein did not (I realise that him, and everybody, were genuinely materialist (through his discussion with Gödel and its correspondence), and Gödel missed it like he missed both the Church-Turing thesis and Mechanism. Another reason is that Gödel did never felt allow to take any position on Quantum Mechanics, to avoid to much hot discussion with the old Einstein.
Recently I got at last the Vol.4 and 5 of the complete work on Gödel (mainly his correspondence). It is interesting to see that Gödel was really deeply fond of metaphysics and theology… And was not materialist, which makes even more sad he missed Mechanism and its necessary immaterialism.
What is nice in the cartoon is that it suggests that philosophy has begun with the question “what is reality made of” (which is materialist at the start, so that this beginning of philosophy was … the beginning of “natural philosophy” which has become physics.
About this, with mechanism, the burden of the proof has changed of camp. Once you understand that elementary arithmetic determines a redundant web of all computations, and that a universal cannot know which computations run itself, except that there are infinitely many, it is up to the believer in matter to either find a different theory of mind than mechanism (and then which one?) or to derive the appearance of the physical reality from the statistic on all (relative) computation (which I did).
The path from Thalès to Pythagorus is a short introduction to the path from “physics is the fundamental science” to “mathematics is the fundamental science” made mandatory once we accept the minimal amount of Mechanism necessary to make sense of Darwin, which took the idea from Descartes (but was already present in antiquity).
Philosophy/metaphysics/theology was mainly the fundamental science before deciding the nature of the ultimate reality. It is the stealing of theology by the “political (tyrannic) power” which destroyed the use of “only reason + experience/observation” in theology, exactly like what happened with biology in the USSR. The whole of science has been “stolen” by the Church, and what we call the Renaissance was only the coming back of the natural science in the domain of reason. For the coming back of theology, it will still take some time, despite the discovery that machines have a transparent mathematical theology with the whole of physics as a testable subpart (and indeed, this is how I found the many histories nature of the physical reality, before realising that many physicist were already there (Everett, non-collapse theories, …).
Science has begun with Pythagorus (OK, with Thalès if you insist) and ended with Damascius. One half of science was resurrected with the arab translation of the greeks texts, but for the human sciences, we need much more “Sophia” (wiseness) than the current available one… As things are going, we might need another millennium of obscurantism before this can happen. Philosophy and theology, not physics, is too much entangled with materialism, and philosophers defends the curriculum of their profession … instead of searching truth…
The “post-modern” *relativist* philosophers continue the *absolute* separation between philosophy and physics, but this only to keep their job, and there is no “real” frontier between any science.
