Excellent essay… this helps me think more clearly about several interesting issues. For example, your distinction at the beginning between mathematical, computational and computable is very helpful. I was also struck by your notion of fundamental physics as a causally closed layer of information processing, which can contain no information about the system that implements it. Altogether you give a very clear and insightful description of the levels of computational complexity arising in nature.

Though it’s not intended as a criticism of your arguments, I do want to suggest that the computational perspective is limited in ways that I think are important. Most basically, it presupposes the existence of definite information in the form of logical bits, along with functional mechanisms that read and write, store and copy, transmit and logically manipulate this information. At the quantum level we have the more complex qbits, which additionally require the so-far unexplained functionality of “measurement” to produce determinate information. Clearly our universe provides all this functionality – but as I suggest in my essay on the natural technologies that support meaningful information, this is not implemented by some underlying invisible hardware layer. Rather, essentially all of atomic and molecular physics operates as a recursively self-sustaining process that defines and continually redefines all its own information.

Likewise when it comes to the technologies of life and of human communication, I think the computational approach needs to be supplemented by an understanding of the different levels of meaning that emerge in the context of self-replicating systems, or systems that can transfer complex information between brains. There is surely a sense in which we can say, “all this is computation.” But as you point out, there are extremely unlikely events like the origin of life – and probably many others, like the origin of eukaryotic cells – that “have to be helped along by a generous number of cosmic dice throws.” These are game-changers, because they suddenly open up new contexts of possibility in which the same computational machinery can begin to operate at a new scale of effectiveness.

So to get a more complete picture, we need to describe both the computational functions and the contexts they operate in, that support them. You could be right that the computational perspective is the great contribution to philosophy made in the last century… but I think we’re only in the first stages of understanding the other side of the picture.

Thanks again for a very fine piece of work.

Nice essay Joscha Bach,

Your ideas and thinking are excellent for eg…

How is it possible for a physical system to have goals? In the way we commonly use the notion, goals have qualities that are different from attractor states that characterize the dynamics of a system’s progression.

Nice essay Joscha Bach,

Your ideas and thinking are excellent for eg…

How is it possible for a physical system to have goals? In the way we commonly use the notion, goals have qualities that are different from attractor states that characterize the dynamics of a system’s progression.

I propose another answer for that direct question….…………

………………… At this point I want you to ask you to please have a look at my essay, where ……………reproduction of Galaxies in the Universe is described. Dynamic Universe Model is another mathematical model for Universe. Its mathematics show that the movement of masses will be having a purpose or goal, Different Galaxies will be born and die (quench) etc…just have a look at my essay… “Distances, Locations, Ages and Reproduction of Galaxies in our Dynamic Universe” where UGF (Universal Gravitational force) acting on each and every mass, will create a direction and purpose of movement…..

I think intension is inherited from Universe itself to all Biological systems

For your information Dynamic Universe model is totally based on experimental results. Here in Dynamic Universe Model Space is Space and time is time in cosmology level or in any level. In the classical general relativity, space and time are convertible in to each other.

Many papers and books on Dynamic Universe Model were published by the author on unsolved problems of present day Physics, for example ‘Absolute Rest frame of reference is not necessary’ (1994) , ‘Multiple bending of light ray can create many images for one Galaxy: in our dynamic universe’, About “SITA” simulations, ‘Missing mass in Galaxy is NOT required’, “New mathematics tensors without Differential and Integral equations”, “Information, Reality and Relics of Cosmic Microwave Background”, “Dynamic Universe Model explains the Discrepancies of Very-Long-Baseline Interferometry Observations.”, in 2015 ‘Explaining Formation of Astronomical Jets Using Dynamic Universe Model, ‘Explaining Pioneer anomaly’, ‘Explaining Near luminal velocities in Astronomical jets’, ‘Observation of super luminal neutrinos’, ‘Process of quenching in Galaxies due to formation of hole at the center of Galaxy, as its central densemass dries up’, “Dynamic Universe Model Predicts the Trajectory of New Horizons Satellite Going to Pluto” etc., are some more papers from the Dynamic Universe model. Four Books also were published. Book1 shows Dynamic Universe Model is singularity free and body to collision free, Book 2, and Book 3 are explanation of equations of Dynamic Universe model. Book 4 deals about prediction and finding of Blue shifted Galaxies in the universe.

With axioms like… No Isotropy; No Homogeneity; No Space-time continuum; Non-uniform density of matter(Universe is lumpy); No singularities; No collisions between bodies; No Blackholes; No warm holes; No Bigbang; No repulsion between distant Galaxies; Non-empty Universe; No imaginary or negative time axis; No imaginary X, Y, Z axes; No differential and Integral Equations mathematically; No General Relativity and Model does not reduce to General Relativity on any condition; No Creation of matter like Bigbang or steady-state models; No many mini Bigbangs; No Missing Mass; No Dark matter; No Dark energy; No Bigbang generated CMB detected; No Multi-verses etc.

Many predictions of Dynamic Universe Model came true, like Blue shifted Galaxies and no dark matter. Dynamic Universe Model gave many results otherwise difficult to explain

Have a look at my essay on Dynamic Universe Model and its blog also where all my books and papers are available for free downloading…
