| 6648 | Some behaviourists believe thought is just suppressed speech [Lowe] |
| Full Idea: Some behaviourists have held the view that thinking just is, in effect, suppressed speech. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 7) | |
| A reaction: He cites J.B.Watson. This would imply that infants and animals can't think. Introspecting my own case, I don't believe it. When I am navigating through a town, for example, I directly relate to my mental map; I see little sign of anything verbal. |
| 6651 | People are wildly inaccurate in estimating probabilities about an observed event [Lowe] |
| Full Idea: In the 'cab problem' (what colour was the cab in the accident?) most people estimate an 80% probability of it being a blue cab, but Bayes' Theorem calculates the probability at 41%, suggesting people put too much faith in eyewitness testimony. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 8) | |
| A reaction: For details of the 'cab problem', see Lowe p.200. My suspicion is that people get into a tangle when confronted with numbers in a theoretical situation, but are much better at it when faced with a real life problem, like 'who ate my chocolate?' |
| 6652 | 'Base rate neglect' makes people favour the evidence over its background [Lowe] |
| Full Idea: 'Base rate neglect' (attending to the witness or evidence, and ignoring background information) is responsible for doctors exaggerating the significance of positive results in diagnosis of relatively rare medical conditions. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 8) | |
| A reaction: This seems to be one of the clearest cases where people's behaviour is irrational, though I suspect that people are much more rational about things if the case is simple and non-numerical. However, people are very credulous about wonderful events. |
| 7715 | Mentalese isn't a language, because it isn't conventional, or a means of public communication [Lowe] |
| Full Idea: 'Mentalese' would be neither conventional nor a means of public communication so that even to call it a language is seriously misleading. | |
| From: E.J. Lowe (Locke on Human Understanding [1995], Ch.7) | |
| A reaction: It is, however, supposed to contain symbolic representations which are then used as tokens for computation, so it seems close to a language, if (for example) symbolic logic or mathematics were accepted as languages. But who understands it? |
| 6655 | The 'Frame Problem' is how to program the appropriate application of general knowledge [Lowe] |
| Full Idea: The 'Frame Problem' in artificial intelligence is how to write a program which not only embodies people's general knowledge, but specifies how that knowledge is to be applied appropriately, when circumstances can't be specified in advance. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 8) | |
| A reaction: As Lowe observes, this is a problem, but not necessarily an impossibility. There should be a way to symbolically map the concepts of knowledge onto the concepts of perception, just as we must do. |
| 6657 | Computers can't be rational, because they lack motivation and curiosity [Lowe] |
| Full Idea: Lack of motivation and curiosity are perhaps the most fundamental reason for denying that computers could be, in any literal sense, rational beings. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 9) | |
| A reaction: I don't see why programmers couldn't move those two priorities to the top of the list in the program. When you switch on a robot, its first words could be 'Teach me something!', or 'Let's do something interesting!' Every piece of software has priorities. |
| 6656 | The Turing test is too behaviourist, and too verbal in its methods [Lowe] |
| Full Idea: The Turing test is open to the objection that it is inspired by behaviourist assumptions and focuses too narrowly on verbal evidence of intelligence. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 8) | |
| A reaction: This is part of the objection that the test exhibits human chauvinism, and robots and aliens are wasting their time trying to pass it. You need human behaviour, especially speech, to do well. Inarticulate people can exhibit high practical intelligence. |
| 6636 | The naturalistic views of how content is created are the causal theory and the teleological theory [Lowe] |
| Full Idea: The leading naturalistic theories of what it is that confers a specific content upon a given attitudinal state are the causal theory, and the teleological theory, both of which contain serious difficulties. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 4) | |
| A reaction: 'Causal' theories (Fodor) say the world directly causes content; 'teleological' theories (Millikan, Papineau) are based on the evolutionary purpose of content for the subject. I agree that neither seems adequate… |
| 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! |
| 6633 | Twin Earth cases imply that even beliefs about kinds of stuff are indexical [Lowe] |
| Full Idea: The implication of considerations of Twin Earth cases is that even beliefs about the properties of kinds of stuff are implicitly indexical, or context-dependent, in character. | |
| From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 4) | |
| A reaction: This is a significant connection, between debates about the nature of indexicals (such as 'I' and 'this') and externalism about content generally. Is there no distinction between objective reference and contextual reference? |
| 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. |
| 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. |
| 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! |
| 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? |
| 16535 | A concept is a way of thinking of things or kinds, whether or not they exist [Lowe] |
| Full Idea: The nearest I can get to a quick definition is to say that a concept is a way of thinking of some thing or kind of things, whether or not a really existent thing or kind of things. | |
| From: E.J. Lowe (What is the Source of Knowledge of Modal Truths? [2013], 2) | |
| A reaction: The focus on 'things' seems rather narrow. Are relations things? He makes concepts sound adverbial, so that there is thinking going on, and then we add 'ways' of doing it. Thinking depends on concepts, not concepts on thinking. |
| 8299 | Abstractions are non-spatial, or dependent, or derived from concepts [Lowe] |
| Full Idea: There are three conceptions of abstractness: 1) non-spatial entities, the opposite of 'concrete' (e.g. numbers and universals); 2) an entity logically incapable of a separate existence (e.g. an apple's colour); 3) Fregean abstractions from concepts. | |
| From: E.J. Lowe (The Possibility of Metaphysics [1998], 10.1) | |
| A reaction: [Lowe p.218 explains the third one] Lowe rejects the third one, and it is a moot point whether the second one could actually be classed as an entity (do they have identity-conditions?), so the big issue is the first one. |
| 4237 | Concrete and abstract objects are distinct because the former have causal powers and relations [Lowe] |
| Full Idea: Concrete objects possess causal powers and relations, but abstract objects are incapable of having causal powers or relations. | |
| From: E.J. Lowe (A Survey of Metaphysics [2002], p.368) | |
| A reaction: Is this an observation or a definition? One might claim that an abstraction (such as a political ideal) can acquire causal power through a conscious mnd. |
| 4238 | The centre of mass of the solar system is a non-causal abstract object, despite having a location [Lowe] |
| Full Idea: The centre of mass of the solar system seems to lack causal powers, and so is an abstract object, even though it has a location and movement. | |
| From: E.J. Lowe (A Survey of Metaphysics [2002], p.368) | |
| A reaction: Nice example, with rich ramifications. Abstraction is deeply tied into our understanding of the physical world, and our concept of identity. |
| 8306 | You can think of a direction without a line, but a direction existing with no lines is inconceivable [Lowe] |
| Full Idea: Although one can separate 'in thought' a direction from any line of which it is the direction, one cannot conceive of a direction existing in the absence of any line possessing that direction. | |
| From: E.J. Lowe (The Possibility of Metaphysics [1998], 10.3) | |
| A reaction: Intriguing. If I ask you to imagine a line going in a certain direction, don't you need the direction before you can think of the line? 'That line is going in the wrong direction'. Maybe abstract ideas only exist 'in thought'. Lowe is a realist here. |
