On:
How units, especially complex multicellular animals, mainly get around in the world in a macroscopic way.
Issues to do with perception/action and in some sense mind.

Gigerenzer, Gut Feelings -"Many skills lack descriptive language"
JJ Gibson -"The environment isn't the same as the physical world"
Maturana etc. -"The [eye's] operations thus have much more the flavour of perception than sensation, if that distinction has any meaning now"

Intuitively much of the real world is alive, whatever that might mean.
The kind of complexity that we observe in living systems is really an order of magnitude (however you might want to measure that) more complex than anything we see in the 'merely' physical world

Physical systems can display non-linear behaviours, pattern forming processes, etc.
When we get to the realm of the living almost none of our reductionistic concepts are too helpful, outside of very narrow contexts

To account for increasingly large and complex systems, we must take an ensemble perspective.

Instead of thinking about what the system is going to do, start thinking about what can the system possibly do what's the state space? what could it possibly do? what configuration could it possibly have? The complement of that is what possibility won't it manifest/actualise?

Determinism can only take us so far - whether it's a fundamental "randomness" or epistemological limitation, doesn't really matter, probabilistic processes become necessary to start dealing with systems & thinking about their future paths/trajectories/possible trajectories.

Epistemological limitations like chaotic dynamics or computation irreducibly introduce uncertainty future states of system.

There are tools that people bring to bear that become selective mechanisms over the possible objects of study and so we get this hugely biased sample of what we consider normal/regular/typical.

DNA is not a blueprint, a common but bad metaphor.
DNA serves as a set of internal instructions to tell a cell what do I do given these inputs from my local environment.

For the past month or so I've been taking @normonics ACS101 which I can thoroughly recommend.
Seeing as we're about half the way through #ACS101 I thought I give a recap of my notes of some of the highlights so far.
