3. Truth / A. Truth Problems / 5. Truth Bearers

8188	Davidson takes truth to attach to individual sentences [Davidson, by Dummett]
	Full Idea: Davidson, by contrast to Frege, has taken truth as attaching to linguistic items, that is, to actual or hypothetical token sentences.
	From: report of Donald Davidson (True to the Facts [1969]) by Michael Dummett - Truth and the Past 1
	A reaction: My personal notion of truth is potentially applicable to animals, so this doesn't appeal to me. I am happy to think of animals as believing simple propositions that never get as far as language, and being right or wrong about them.

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.

19. Language / D. Propositions / 3. Concrete Propositions

19216	Propositions (such as 'that dog is barking') only exist if their items exist [Williamson]
	Full Idea: A proposition about an item exists only if that item exists... how could something be the proposition that that dog is barking in circumstances in which that dog does not exist?
	From: Timothy Williamson (Necessary Existents [2002], p.240), quoted by Trenton Merricks - Propositions
	A reaction: This is a view of propositions I can't make sense of. If I'm under an illusion that there is a dog barking nearby, when there isn't one, can I not say 'that dog is barking'? If I haven't expressed a proposition, what have I done?
