The clear distinction between determinism and randomness dates back to Newton and his "laws" of gravitational motion. In fact what Newton actually showed is that no such "laws" exist because the motion of every single physical entity in the universe is causally affected by the motion of every other. In other words relativistic gravitational motion is universally
self-causal, or chaotic. Self-causal systems spontaneously self-organise into progressively more complex internal structures through the agency of no law beyond the meta-law of cause and effect, a fundamental fact of nature which we now understand as the
process of evolution, a process which was unknown to Newton. It is these spontaneously self-generating patterns of self-organisation which science seeks to model in terms of Newton's "laws of nature" but this terminology is deceptive and misleading. These so-called "laws" are nothing more than clever and convenient heuristics devised by the consciousness of the observer to give meaning to the self-causal world which he observes.
None of this language exists in
Principia. I think you are doing little more than imposing your own anachronistic stance onto Newton. So you are really missing the historical significance of Newton, and wrongly claiming that the determinism/randomness dates back to Newton, when there are many pre-Newtonian examples - Epicurus for one.
It sounds like your Hobby Horse.
The unpredictability of self-organising stochastic processes is NOT a function of randomness but a function of the intrinsic complexity of the causal dynamics of the entire physical universe.
I think I already said this. The only thing I prefer to state, is that since we empty the idea of randomness everyday, rather than claim there is no such thing, we ought to say exactly what we mean by it. So yeah you can't predict a roulette wheel in normal circumstances, and whilst I agree it's not conforming to some sort of law of randomness, it is reliably "random".
This is not a statement of opinion but a statement of universally accepted FACT. No physicist in the world will deny that the motion of every physical entity in the universe must necessarily affect the motion of every other and that the effect of these relativistic motions is propagated through time at the speed of light. Therefore the future can be entirely determined by the present and yet remain utterly unknowable.
again, you are preaching to the converted.
The only thing we can know for certain about the future is that it will be more complex than the past, because evolution from the simple to the complex is the fundamental self-organising principle of nature, a universal statement of fact supported by 13.8 billion years worth of evidence.
I think not. From our narrow human metric we might consider a brain to be more complex than a quart of sand, but the exact disposition of all the atoms in the sand is not less complex than those in a brain. We just are more interested in the complexity of a brain because it has more meaning to us as living beings. Were we an atom of water trying to plot a passage through the sand it would be as complex.
As for the rest of the universe, who really knows. Maybe the last supernova in a neighbouring galaxy just wiped out the most complex and advanced civilisation since the dawn of time last week?
It also looks likely that the inevitable consequence is the heat death of the universe in which all complexity is reduced to a warm fuzz.
