8833 | Why should we prefer coherent beliefs? [Klein,P] |
Full Idea: A key question for a coherentist is, why should he or she adopt a coherent set of beliefs rather than an incoherent set? | |
From: Peter Klein (Infinitism solution to regress problem [2005], 'Step 1') | |
A reaction: The point of the question is that the coherentist may have to revert to other criteria in answering it. One could equally ask, why should I believe in tables just because I vividly experience them? Or, why believe 2+2=4, just because it is obvious? |
8834 | Infinitism avoids a regress, circularity or arbitrariness, by saying warrant just increases [Klein,P] |
Full Idea: Infinitism can solve the regress problem, because it endorses a warrant-emergent form of reasoning in which warrant increases as the series of reasons lengthens. The theory can avoid both circularity and arbitrariness. | |
From: Peter Klein (Infinitism solution to regress problem [2005], 'Step 2') | |
A reaction: It nicely avoids arbitrariness by offering a reason for absolutely every belief. I think the way to go may to combine individual Infinitism with a social account of where to set the bar of acceptable justification. |
8838 | If justification is endless, no link in the chain is ultimately justified [Ginet on Klein,P] |
Full Idea: An endless chain of inferential justifications can never ultimately explain why any link in the chain is justified. | |
From: comment on Peter Klein (Infinitism solution to regress problem [2005]) by Carl Ginet - Infinitism not solution to regress problem p.148 | |
A reaction: This strikes me as a mere yearning for foundations. I don't see sense-experience or the natural light of human reason (or the word of God, for that matter) as in any way 'ultimate'. It's all evidence to be evaluated. |
8839 | Reasons acquire warrant through being part of a lengthening series [Klein,P] |
Full Idea: The infinitist holds that finding a reason, and then another reason for that reason, places it at the beginning of a series where each gains warrant as part of the series. ..Rational credibility increases as the series lengthens. | |
From: Peter Klein (Infinitism solution to regress problem [2005], p.137) | |
A reaction: A striking problem here for Klein is the status of the first reason, prior to it being supported by a series. Surprisingly, it seems that it would not yet be a justification. Coherence accounts have the same problem, if coherence is the only criterion. |
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? |
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. |
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. |
6005 | Animals are dangerous and nourishing, and can't form contracts of justice [Hermarchus, by Sedley] |
Full Idea: Hermarchus said that animal killing is justified by considerations of human safety and nourishment and by animals' inability to form contractual relations of justice with us. | |
From: report of Hermarchus (fragments/reports [c.270 BCE]) by David A. Sedley - Hermarchus | |
A reaction: Could the last argument be used to justify torturing animals? Or could we eat a human who was too brain-damaged to form contracts? |
