Episode 96 - About the philosophy of realism and the pinnacle of all realism claims: the Church-Turing-Deutsch thesis

Author: Bart Vanderhaegen August 5, 2021 Duration: 14:40

The Church-Turing-Deutsch thesis: Every physical process can be simulated, to arbitrary precision, by a universal computing device.

This claim seems to be the pinnacle claim of all realist claims, I go into it's various consequences for realism

  1. There is a reality out there - actually 1 reality
  2. We can create knowledge about that reality
  3. That knowledge is not only descriptive but also explanatory (given that a computer program is an explanation)
  4. Our knowledge can grow, matching reality eventually to arbitrary precision
    1. Reality is deterministic
    2. Physical processes are equivalent to computations. Computations cause physical stuff to move. So computations have causal power. So there are 2 types of causation : the laws of physics and knowledge (computer programs)
  5. Given that our brains are Turing machines we are universal computers: we can understand everything once given the program
  6. Given that there are no barriers to evolving our algorithms and create knowledge, we are also universal explainers: we can discover all theories that match reality to arbitrary precision
  7. If morality and aesthetics involve physical processes (like suffering in morality or attraction in aesthetics) then we can objectively simulate morality and aesthetics as well. Making them also fields of objective knowledge, independent of our minds

So if you a "real realist", say you endores the CTD thesis ;-)


Bart Vanderhaegen hosts Rapid Idea Improvement, a podcast that digs into a powerful and practical question: how do ideas actually get better? Instead of staying in the abstract, it applies the principles of knowledge growth-particularly those from thinkers like Karl Popper and David Deutsch-to the messy, real-world domains of business, management, and economics, while also reaching into fields like physics for broader insight. Each episode is an exploration of critical rationalism in action, examining how we can systematically criticize and refine our thinking to solve problems more effectively. You’ll hear discussions that treat business challenges not as puzzles with fixed answers, but as opportunities for evolutionary idea improvement, where bold conjectures and rigorous error-correction drive progress. This isn't about motivational tips or surface-level analysis; it's about building a deeper framework for understanding how knowledge expands, and then using that framework to make your own thinking more potent and adaptable. The conversations in this podcast are for anyone who suspects that the way we approach problems-in leadership, strategy, or innovation-can be fundamentally upgraded. By weaving together epistemology with practical application, the show aims to provide listeners with a genuinely useful toolkit for accelerating the development of their most important ideas.

Decarbonisation can (and should) be evaluated in terms of how effectively it reaches its goal, or in other words, how well it solves the problem it purports to solve.
