23805 | Some explanations offer to explain a mystery by a greater mystery [Schulte] |
Full Idea: An 'obscurum per obscurius' explanation is explaining something mysterious by something even more mysterious, | |
From: Peter Schulte (Mental Content [2023], 6) | |
A reaction: Schulte's example is trying to explain mental content in terms of phenomenal experience. That is, roughly, explaining content by qualia, when the latter is the 'hard problem'. |
4608 | Minds are hard-wired, or trial-and-error, or experimental, or full self-aware [Dennett, by Heil] |
Full Idea: Dennett identifies a hierarchy of minds running from 'Darwinian' (hard-wired solutions to problems), to 'Skinnerian' (trial-and-error), to 'Popperian' (anticipating possible experience), to 'Gregorian' (self-conscious representation, probably linguistic). | |
From: report of Daniel C. Dennett (Kinds of Minds [1996]) by John Heil - Philosophy of Mind Ch.5 | |
A reaction: Interesting. The concept of an experiment seems a major step (assessing reality against an internal map), and the ability to think about one's own thoughts certainly strikes me as the mark of a top level mind. Maybe that is the importance of language. |
4880 | Sentience comes in grades from robotic to super-human; we only draw a line for moral reasons [Dennett] |
Full Idea: 'Sentience' comes in every imaginable grade or intensity, from the simplest and most 'robotic', to the most exquisitely sensitive, hyper-reactive 'human'. We have to draw a line for moral policy, but it is unlikely we will ever discover a threshold. | |
From: Daniel C. Dennett (Kinds of Minds [1996], Ch.4) | |
A reaction: This is the only plausible view, if you take the theory of evolution seriously. We can even observe low-grade marginal sentience in our own minds, and then shoot up the scale when we focus our minds properly on an object. |
3488 | Freud treats the unconscious as intentional and hence mental [Freud, by Searle] |
Full Idea: Freud thinks that our unconscious mental states exist as occurrent intrinsic intentional states even when unconscious. Their ontology is that of the mental, even when they are unconscious. | |
From: report of Sigmund Freud (works [1900]) by John Searle - The Rediscovery of the Mind Ch. 7.V | |
A reaction: Searle states this view in order to attack it. Whether such states are labelled as 'mental' seems uninteresting. Whether unconscious states can be intentional is crucial, and modern scientific understanding of the brain strongly suggest they can. |
4873 | What is it like to notice an uncomfortable position when you are asleep? [Dennett] |
Full Idea: What is it like to notice, while sound asleep, that your left arm has become twisted into a position in which it is putting undue strain on your left shoulder? Like nothing. | |
From: Daniel C. Dennett (Kinds of Minds [1996], Ch.1) | |
A reaction: A nice question, and all part of Dennett's accurate campaign to show that consciousness is not an all-or-nothing thing. As when we are barely aware of driving, innumerable things happen in the shadowy corners of thought. |
4881 | Being a person must involve having second-order beliefs and desires (about beliefs and desires) [Dennett] |
Full Idea: An important step towards becoming a person is the step up from a first-order intentional system to a second-order system (which has beliefs and desires about beliefs and desires). | |
From: Daniel C. Dennett (Kinds of Minds [1996], Ch.5) | |
A reaction: Call it 'meta-thought'. I agree. Dennett thinks language is crucial to this, but the hallmark of intelligence and full-blown personhood is meta- and meta-meta-thought. Maybe the development of irony is a step up the evolutionary scale. Sarcasm is GOOD. |
5689 | Freud and others have shown that we don't know our own beliefs, feelings, motive and attitudes [Freud, by Shoemaker] |
Full Idea: Freud persuaded many that beliefs, wishes and feelings are sometimes unconscious, and even sceptics about Freud acknowledge that there is self-deception about motive and attitudes. | |
From: report of Sigmund Freud (works [1900]) by Sydney Shoemaker - Introspection p.396 | |
A reaction: This seems to me obviously correct. The traditional notion is that the consciousness is the mind, but now it seems obvious that consciousness is only one part of the mind, and maybe even a peripheral (epiphenomenal) part of it. |
4875 | We descend from robots, and our intentionality is composed of billions of crude intentional systems [Dennett] |
Full Idea: We are descended from robots, and composed of robots, and all the intentionality we enjoy is derived from the more fundamental intentionality of billions of crude intentional systems. | |
From: Daniel C. Dennett (Kinds of Minds [1996], Ch.2) | |
A reaction: A more grand view of intentionality (such as Searle's) seems more attractive than this, but the crucial fact about Dennett is that he takes the implications of evolution much more seriously than other philosophers. He's probably right. |
4879 | There is no more anger in adrenaline than silliness in a bottle of whiskey [Dennett] |
Full Idea: There is no more fear or anger in adrenaline than there is silliness in a bottle of whiskey. | |
From: Daniel C. Dennett (Kinds of Minds [1996], Ch.3) | |
A reaction: Not exactly an argument, but a nice rhetorical point against absurd claims about identity and reduction and elimination. We may say that there is no fear without adrenaline, and no adrenaline in a live brain without fear. |
4876 | Maybe there is a minimum brain speed for supporting a mind [Dennett] |
Full Idea: Perhaps there is a minimum speed for a mind, rather like the minimum escape velocity required to overcome gravity and leave the planet. | |
From: Daniel C. Dennett (Kinds of Minds [1996], Ch.3) | |
A reaction: Dennett rejects this speculation, but he didn't stop to imagine what it would be LIKE if your brain slowed down, and he never considers Edelman's view that mind is a process. Put the two together… |
4878 | The materials for a mind only matter because of speed, and a need for transducers and effectors [Dennett] |
Full Idea: I think there are only two good reasons why, when you make a mind, the materials matter: speed, and the ubiquity of transducers and effectors throughout the nervous system. | |
From: Daniel C. Dennett (Kinds of Minds [1996], Ch.3) | |
A reaction: This sounds roughly right, because it gives you something between multiple realisability (minds made of cans and string), and type-type identity (minds ARE a particular material). Call it 'biological functionalism'? |
23950 | Freud said passions are pressures of some flowing hydraulic quantity [Freud, by Solomon] |
Full Idea: Freud argued that the passions in general …were the pressures of a yet unknown 'quantity' (which he simply designated 'Q'). He first thought this flowed through neurones, …and always couched the idea in the language of hydraulics. | |
From: report of Sigmund Freud (works [1900]) by Robert C. Solomon - The Passions 3.4 | |
A reaction: This is the main target of Solomon's criticism, because its imagery has become so widespread. It leads to talk of suppressing emotions, or sublimating them. However, it is not too different from Nietzsche's 'drives' or 'will to power'. |
4874 | The predecessor and rival of the language of thought hypothesis is the picture theory of ideas [Dennett] |
Full Idea: The ancestor and chief rival of the language-of-thought hypothesis is the picture theory of ideas - that thoughts are about what they are about because they resemble their objects. | |
From: Daniel C. Dennett (Kinds of Minds [1996], Ch.2) | |
A reaction: When you place them side by side, neither seems quite right. How can a mental state resemble an object, and how can an inner language inherently capture the features of an object? Maybe we lack the words for the correct theory. |
23792 | Phenomenal and representational character may have links, or even be united [Schulte] |
Full Idea: Some theorists maintain that all states with representational content or intentionality must have phenomenal character …and we can also ask whether all states with phenomenal character also have representional content. | |
From: Peter Schulte (Mental Content [2023], 2.4) | |
A reaction: He mentions that beliefs could involve inner speech. And pains and moods may be phenomenal but lack content. He also asks which determines which. |
23795 | Naturalistic accounts of content cannot rely on primitive mental or normative notions [Schulte] |
Full Idea: A 'naturalistic' explanation of content excludes primitive mental or normative notions, but allows causation, counterfactual dependence, probabilistic dependence or structural similarity. | |
From: Peter Schulte (Mental Content [2023], 4) | |
A reaction: Apart from causation, what is permissible to naturalists (like me) all sounds rather superficial (and thus not very explanatory). I'm sure we can do better than this. How about using non-primitive mental notions? |
23804 | Maybe we can explain mental content in terms of phenomenal properties [Schulte] |
Full Idea: The phenomenal intentionality approach says that the content properties of mental states can be explained in terms of the phenomenal properties of mental states. | |
From: Peter Schulte (Mental Content [2023], 6) | |
A reaction: [Searle and Loar are cited] Tends to be 'non-naturalistic'. We might decide that content derives from the phenomenal, but still without saying anything interesting about content. Mathematical content? Universally generalised content? |
23793 | On the whole, referential content is seen as broad, and sense content as narrow [Schulte] |
Full Idea: We can say that non-Fregean content [reference] is (virtually) always contrued as broad, while Fregean content [sense] is usually contrued as narrow. | |
From: Peter Schulte (Mental Content [2023], 3.2) | |
A reaction: I can't make sense of mental content actually being outside the mind, so I see all content as narrow - but that doesn't mean that externals are irrelevant to it. If I think that is an oak, and it's an elm, the content is oak. |
23796 | Naturalists must explain both representation, and what is represented [Schulte] |
Full Idea: Naturalistic accounts of content ask 1) what makes a state qualify as a representational state?, and 2) what makes a representational state have one specific content rather than another? | |
From: Peter Schulte (Mental Content [2023], 4) | |
A reaction: [As often in this collection, the author uses algebraic letters, but I prefer plain English] I would say that the first question looks more amenable to an answer than the second. Do we know the neuronal difference between seeing red and blue? |
23806 | Naturalist accounts of representation must match the views of cognitive science [Schulte] |
Full Idea: Recent naturalisation of content now also has to offer a matching account of representational explanations in cognitive science. | |
From: Peter Schulte (Mental Content [2023], 08.1) | |
A reaction: [He cites Cummins, Neander and Shea] This is in addition to the 'status' and 'content' questions of Idea 23796. This seems to be an interesting shift to philosophers working backwards from the theories of empirical science. Few are qualified for this job! |
23802 | Conceptual role semantics says content is determined by cognitive role [Schulte] |
Full Idea: Conceptual role semantics says the content of a representation is determined by the cognitive role it plays with a system. | |
From: Peter Schulte (Mental Content [2023], 4.5) | |
A reaction: Obvious problem: if 'swordfish' is the password, its role is quite different from its content. I've never thought that the role of something tells you anything about what it is. Hearts pump blood, but how do they fulfil that role? |
23797 | Cause won't explain content, because one cause can produce several contents [Schulte] |
Full Idea: A simple causal theory of content has the 'content indeterminacy' problem - that the presence of a cow causes 'a cow is present', but also 'an animal is present' and 'a biological organism is present'. | |
From: Peter Schulte (Mental Content [2023], 4.1) | |
A reaction: That only rules out the 'simple' version. We just need to add that the cause (cow experience) is shaped by current knowledge and interests. Someone buying cows and someone terrified of them thereby produce different concepts. |
23800 | Teleosemantic explanations say content is the causal result of naturally selected functions [Schulte] |
Full Idea: Teleosemantic theories usually give a causal account of mental functions …where some trait has a particular function if it was selected for that function by a process of natural selection. | |
From: Peter Schulte (Mental Content [2023], 4.4) | |
A reaction: This is an idea I like - that something has a specific function if without that function it wouldn't have come into existence (eyes, for example). But presumably the function of a mind is to collect content - which does nothing to explain content! |
23799 | Teleosemantics explains content in terms of successful and unsuccessful functioning [Schulte] |
Full Idea: The core idea of teleosemantics is that we need to explain how content can be accurate or inaccurate, true or false, realised or unrealised …which must appeal to the distinction between proper functioning and malfunctioning. | |
From: Peter Schulte (Mental Content [2023], 4.4) | |
A reaction: My immediate reaction to this is that you don't learn about content by assessing its success. Surely (as with eyesight) you first need to understand what it does, and only then judge its success. …Though success and failure are implicit in function. |
23798 | Information theories say content is information, such as smoke making fire probable [Schulte] |
Full Idea: Information theories of content [usually assume that] a column of smoke over there carries the information that fire is over there because it raises the probability of fire being over there. | |
From: Peter Schulte (Mental Content [2023], 4.2) | |
A reaction: Theorists usually add further conditions to this basic one. Fred Dretske is the source of this approach. Not promising, in my opinion. Surely the content is just smoke, and fire is one of dozens of possible inferences from it? |
4882 | Concepts are things we (unlike dogs) can think about, because we have language [Dennett] |
Full Idea: A dog cannot consider its concepts. Concepts are not things in a dog's world in the way that cats are. Concepts are things in our world, because we have language. | |
From: Daniel C. Dennett (Kinds of Minds [1996], Ch.6) | |
A reaction: Dogs must have concepts, though, or much of their behaviour (like desperation to go for a walk, or to eat) is baffling. This is as good a proposal as I have ever encountered for the value of language. Meta-thought is a huge evolutionary advantage. |
22344 | Freud is pessimistic about human nature; it is ambivalent motive and fantasy, rather than reason [Freud, by Murdoch] |
Full Idea: Freud takes a thoroughly pessimistic view of human nature. ...Introspection reveals only the deep tissue of ambivalent motive, and fantasy is a stronger force than reason. Objectivity and unselfishness are not natural to human beings. | |
From: report of Sigmund Freud (works [1900], II) by Iris Murdoch - The Sovereignty of Good II | |
A reaction: Interesting. His view seems to have coloured the whole of modern culture, reinforced by the hideous irrationality of the Nazis. Adorno and Horkheimer attacking the Enlightenment was the last step in that process. |
4872 | Most people see an abortion differently if the foetus lacks a brain [Dennett] |
Full Idea: If a fetus that is being considered for abortion is known to be anencephalic (lacking a brain), this dramatically changes the issue for most people, though not for all. | |
From: Daniel C. Dennett (Kinds of Minds [1996], Ch.1) | |
A reaction: A very effective point, as it is hard to see what grounds could be given for not aborting in this case. But the brain then clearly becomes the focus of why abortion is often rejected by many people. |
4877 | Maybe plants are very slow (and sentient) animals, overlooked because we are faster? [Dennett] |
Full Idea: Might plants just be 'very slow animals', enjoying sentience that has been overlooked by us because of our human timescale chauvinism? | |
From: Daniel C. Dennett (Kinds of Minds [1996], Ch.3) | |
A reaction: Delightful thought, arising from pondering the significance of the speed of operation of the brain. I think it is false, because I think high speed is essential to mind, and Dennett seems not to. |
