10 ideas
23513 | Single neurons can carry out complex functions [Seth] |
Full Idea: It is increasingly apparent that even single neurons are capable of carrying out highly complex functions all by themselves. | |
From: Anil Seth (Being You [2021], I.1 n) | |
A reaction: Bang goes the simple connectionist account of consciousness. |
23514 | The cerbellum has a huge number of neurons, but little involvement in consciousness [Seth] |
Full Idea: The cerebellum [at the back] has about four times as many neurons as the rest of the brain put together, but seems barely involved in consciousness. | |
From: Anil Seth (Being You [2021], I.2) | |
A reaction: I wonder if it also has four times as many connections? |
23516 | Maybe a system is conscious if the whole generates more information than its parts [Seth] |
Full Idea: The main claim of Tononi's 'integrated information theory' is that a system is conscious to the extent that its whole generates more information than its parts. | |
From: Anil Seth (Being You [2021], I.3) | |
A reaction: Seth seems to present this as an 'interesting' proposal. I find it unlikely that consciousness could be explain in terms of information, or that a machine constructed on this principle would thus become conscious. (Databases pass this test). |
23519 | The self is embodied, perspectival, volitional, narrative and social [Seth, by PG] |
Full Idea: The elements of a self are 1) embodied - related directly to the body, 2) perspectival - having a viewpoint, 3) volitional - being an agent, 4) narrative - aware of past and future, and 5) social - as others perceive me. | |
From: report of Anil Seth (Being You [2021], III.8) by PG - Db (ideas) | |
A reaction: [summarised] Seth says there are distinctive emotions associated with each of these aspects of the self. This list is very helpful, as a discouragement for anyone who wants to pick one of these as the sole true nature of the self. |
23518 | Modern AI is mostly machine-based pattern recognition [Seth] |
Full Idea: Much of today's AI is best described as sophisticated machine-based pattern recognition. | |
From: Anil Seth (Being You [2021], IV.13) | |
A reaction: Personally I wouldn't want to underestimate the extent to which human intelligence is also pattern recognition (across time as well as in space). |
23517 | Volition is felt as doing what you want, with possible alternatives, and a source from within [Seth] |
Full Idea: The experience of volition is defined by 1) the feeling that I am doing what I want to do, 2) that I could have done otherwise, and 3) that voluntary actions seem to come from within. | |
From: Anil Seth (Being You [2021], III.11) | |
A reaction: Note that these can all be cited without reference to their feeling 'free'. |
23515 | Human exceptionalism plagues biology, and most other human thinking [Seth] |
Full Idea: Human exceptionalism has repeatedly plagued biology, and has darkened the history of human thought everywhere. | |
From: Anil Seth (Being You [2021], I.2) | |
A reaction: I increasingly agree with this, as much in philosophy as in biology. We really need to get used to our place in evolution. |
20645 | Heat is a state of vibration, not a substance [Joule] |
Full Idea: We consider heat not as a substance but as a state of vibration. | |
From: James Joule (works [1870]), quoted by Peter Watson - Convergence 01 'Nature's' | |
A reaction: The puzzle is that giving accurate accounts of vibrations, heat and movement require a quantitative substance, energy. But all we have here is movement, and the denial of a substance. Energy is 'nature's currency system'. |
20972 | Joule showed that energy converts to heat, and heat to energy [Joule, by Papineau] |
Full Idea: James Joule established the equivalence of heat and mechanical energy, in the sense of showing that a specific amount of heat will always be produced by the expenditure of a given amount of energy, and vice versa. | |
From: report of James Joule (works [1870]) by David Papineau - Thinking about Consciousness App 4.2 | |
A reaction: This was a major step towards the law of conservation of energy. |
1513 | The Egyptians were the first to say the soul is immortal and reincarnated [Herodotus] |
Full Idea: The Egyptians were the first to claim that the soul of a human being is immortal, and that each time the body dies the soul enters another creature just as it is being born. | |
From: Herodotus (The Histories [c.435 BCE], 2.123.2) |
