15. Nature of Minds / A. Nature of Mind / 8. Brain

23226	There is a single mouse neuron which has 862 inputs and 626 outputs [Cobb]
	Full Idea: Researchers have recently described a single inhibitory neuron in a region called the visual thalamus of the mouse - it has 862 input synapses and 626 output synapses.
	From: Matthew Cobb (The Idea of the Brain [2020], 11)
	A reaction: This is the kind of fact which philosophers of mind must be aware of when offering accounts of thought which are in danger of being simplistic.

23216	The brain is not passive, and merely processing inputs; it is active, and intervenes in the world [Cobb]
	Full Idea: A number of scientists are now realising that, by viewing the brain as a computer that passively responds ot inputs and processes data, we forget that it is an active organ, part of the body intervening in the world.
	From: Matthew Cobb (The Idea of the Brain [2020], Intro)
	A reaction: I like any idea which reminds us that nature is intrinsically active, and not merely passive. Laws are in nature, not imposed on it. My preferred ontology, based on powers as fundamental, applies to the brain, as well as to physics. No free will needed.

17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / a. Physicalism critique

6382	The 'grain problem' says physical objects are granular, where sensations appear not to be [Sellars, by Polger]
	Full Idea: Sellars' Grain Problem contended that it was a problem for materialism that physical objects have a granularity whereas sensations are homogeneous and without grain.
	From: report of Wilfrid Sellars (Empiricism and the Philosophy of Mind [1956], Ch. n22) by Thomas W. Polger - Natural Minds Ch.1 n22
	A reaction: This doesn't strike me as a serious problem. I assume that my sensations are granular, but at a level too fine for me to introspect. There are three hundred trillion connections in the brain (Idea 2952), a lot of them involved in sensations.

27. Natural Reality / E. Cosmology / 1. Cosmology

5994	Is the cosmos open or closed, mechanical or teleological, alive or inanimate, and created or eternal? [Robinson,TM, by PG]
	Full Idea: The four major disputes in classical cosmology were whether the cosmos is 'open' or 'closed', whether it is explained mechanistically or teleologically, whether it is alive or mere matter, and whether or not it has a beginning.
	From: report of T.M. Robinson (Classical Cosmology (frags) [1997]) by PG - Db (ideas)
	A reaction: A nice summary. The standard modern view is closed, mechanistic, inanimate and non-eternal. But philosophers can ask deeper questions than physicists, and I say we are entitled to speculate when the evidence runs out.
