substance metaphysics and have been looking toward process metaphysics (e.g. Whitehead). Mark Bickhard claims that interactivism requires a process metaphysics framework, but I am not well versed enough in process philosophy to say more at this time. 3/3

as a primitive, but one which is unknowable. I see this as different from materialist panpsychism as I do not accept the claim that consciousness is a property of matter. That view is fraught with difficulties. In general though, I have been questioning the validity of 2/n

Not sure I have much insight. I will say that I’m not a physicalist and I do not think that science (or language in general) has the ability to comprehend consciousnes via some model of it. In that sense, I’m in favor of an absolute idealism which takes consciousness 1/n

I often wonder the same thing. I think that the politics of academia don’t currently allow for crowdsourcing sense-making. I also think that most scientists in academia don’t really think in terms of sense-making, they seem to think more in terms of “objective discovery”.

The labels on the edges between nodes will definitely come later. I’m mostly making the graph because I felt I didn’t have a good grasp on all the different positions in cog sci, their arguments, and historical and counter argument relationships to each other.

Hard to say yet, only just got started reading him. I really started making this network to explore and understand his work among many others. He got me to start considering representation again (I was an eliminativist for a while).

In JavaScript I’m using the library vis.js to construct the network. The rest is HTML and CSS. When you click on a node, a paragraph pops up explaining that node in the context of the ones around it. Is there a big difference between semantic networks and knowledge graphs?

Slowly but surely, my semantic network web app exploring the foundations of cognitive science is coming along. I decided to write in JavaScript rather than Python. pic.twitter.com/pjwX62MZCg

Tadashi Tokieda offers a nice discussion of this towards the end of this video:

I need to read more Vygotsky. Where should I start for a deep dive?

A great reminder that even though many experimentalists claim to be “theory-free”, their analyses and interpretations of their experiments are inherently theory laden by models of their measurements and measuring apparatuses. twitter.com/betanalpha/sta…

I got started with self organizational processes by reading Maturana and Varela’s work on autopoiesis. Their book “Autopoiesis” is a bit dense, so I’d recommend this nice book called “The Systems View of Life” by Capra and Luisi.

Can’t say that I’ve found one yet. I used to be an eliminativist about representation, but I started reading about Mark Bickhard’s “interactivist” account of representation and he’s opening my mind to representation again. Only 60 pages into the book, so I can’t fully buy in yet.

Is there some version of Taken’s theorem for cellular automata? How does one usually construct state space embeddings for CAs?

Was not aware of this. Do you have some good examples of toy models where these methods fail that you can point me to?

Looks like they didn’t even bother to estimate Lyapunov exponents or fractal dimension of the time series to try and rule out chaos. Unfortunately chaos theory got a bad rap in the 90s and late 80s and isn’t being taken too seriously by experimental neuroscientists these days.

What do we mean we talk about “internal states” in a discrete way? It seems that really we are talking about equivalence classes of states at some coarse-grained scale. But how do we construct equivalence classes over states? How do we demarcate their temporal boundaries? pic.twitter.com/rS8Jhsjb7V

Something like this must happen for theoretical neuroscience. There are similar initiatives, i.e. simonsfoundation.org/2016/11/24/neu…. But whether it can work is another question. We’re in the middle of an ontological crisis; not a lot of consensus and poor philosophical foundations.

What class of physical processes are we talking about? There are certainly many stable processes that do not have low dimensional descriptions. Some forms of intrinsic bursting in neurons, for example, cannot be characterized in less than four dimensions.
