Campbell, 1974, essay found in "The Philosophy of Karl Popper"), which holds that knowledge emerges through variation and selective retention. As Karl Popper put it, "We choose the theory which best holds its own in competition with other theories; the one which, by natural selection, proves itself the fittest to survive."
On this view, learning in general operates via selection under uncertainty. This is less visible in individual cognition, where we tend to over-attribute agency, but it is explicit in science: hypotheses are proposed, subjected to tests, and selectively retained, precisely because the future cannot be deduced from the present.
In that sense, generation/discrimination is a particular implementation of this broader principle (a way of instantiating variation and selection) not the primitive itself.
I agree, I meant to be explicit that the one rule was "gravity";
Variation (chaos) comes from the tidal push/pull of all cumulative processes - all processes are nearly periodic (2nd law) and get slower - guaranteeing oscillator harmonics at intervals.
These intervals are astronomically convulted, but still promise a Fourier distribution of frequency: tidal effects ensure synchronization eventually, as all periods resonate eventually.
As systems are increasingly exposed to pendulums of positive and negative coherence, they will generalize for variance, and eventually for increasingly (fourier) selective filters of increasingly resiliente traits, that will generalize.
The system would eventually be increasingly resilient and eventually an awareness would develop.
Awareness of past periodic cycles would improve fitness (with or without consciousness) and eventually the mechanistic processes would be in the systems nature.
This is why we have pointless traditions, folk lore, collective unconscious artifacts, cyclical cataclysmic religions, the Fermi Paradox, the great filters...
Variation and selection are woven, but understanding how it all stems from gravity by means of nearly perioidic oscillators (spinning planets, tidal pools, celestial bodies) due to the conservation of angular momentum, due to the 3body problem.....that is what took a genius to reconcile
