i don't think we really know how cortex does translation invariance.

i think we know quite a bit about it.

Well, your thesis gives some well-known facts about cortical circuits and derives one possible theory of what those circuits might be doing, but I don't think there is anything like proof there, unless there is some recent study I don't know about.

Gary you know this well, there is nothing called proof is science. This is not mathematics. We can talk about evidence...

sure, but i don't think there is compelling evidence; feel free to lay it out if you disagree. but no neuroscientist that i have spoken with in last six months (or six years) is of the opinion that there is anything yet like clarity about how the brain works. cc @AdamMarblestone

It could be that you are asking the wrong questions to these neuroscientists. If you ask "do you know how the brain works" they will say no, and mostly cog-scientists will say no if you ask them "do you know how the mind works?".

That's assuming you talk to the honest ones. Many of them will in fact say yes and then start waving their hands and draw useless diagrams on a whiteboard.

Agree. "Do you know how the brain/mind works" is also the wrong question. Gary doesn't know how the mind works...why are neurocientists held to a different standard from cogsci?
