A profound thought from @chrisfields38.bsky.social: Your environment is a cognitive agent.

He shared it here (minute 18) in the context of quantum information theory

I like this paper, and not just for the obvious reason. A great summary of where we stand in thinking about types of mind. Nice also to see this made explicit: "All living systems share a fundamental property: agency."

Intelligence and consciousness.

@anilseth.bsky.social, brief, clear and to the point: "intelligence is about doing and consciousness is about being"

Why consciousness is more likely a property of life than of computation and why creating conscious, or even conscious-seeming AI, is a bad idea.

@chrisfields38.bsky.social on recursion in interpreting something as a computation. - You need to compute in oder to claim that "ABC" is doing computation. E.g. imagine you're stating that a crow is doing addition - you can't do that unless you do addition in your head.

Space and object permanence.
@chrisfields38.bsky.social in addition to connecting time and identity does the same with space. When we see a ball moving, we must assume it is the same ball and not the series of balls disappearing and appearing - we need identity assumption to perceive something

function of space? citation from @chrisfields38.bsky.social "space allows us to keep different packets of information away from each other, so they don't interfere. To be able to distinguish information about some-thing from information about something else."

In our paper with @chrisfields38.bsky.social @drmichaellevin.bsky.social @activeinference.bsky.social @lancelotdacosta.bsky.social we mentioned a dysfunction of a specific memory system as one of the possible underlying mechanism of a dissociative episode. The paper is about temporal depth, however

@chrisfields38.bsky.social's comment derived from the 2nd law: given your observation capabilities, whatever direction you see the most information loss is your local, entropic time direction.

Kudos to Gary for realising and saying this ages ago. But bugger me, why were the "big guns" so slow to realise it too, and how much faith can we have in their judgement?

Almost always we average responses thus equating response variability with noise.
Well, we shouldn't because variability is also signal, not noise to be entirely discarded.
