| 5806 | Belief is the power of metarepresentation [Dretske] |
| Full Idea: Belief is the power of metarepresentation. | |
| From: Fred Dretske (Naturalizing the Mind [1997], §2.3) | |
| A reaction: Hm. I have always defined belief as 'commitment to truth', and this definition leaves out both parts. Where is the commitment? If hope is another metarepresentation, how does it differ from belief? I imagine things, not believing them to be true. |
| 5801 | A mouse hearing a piano played does not believe it, because it lacks concepts and understanding [Dretske] |
| Full Idea: A mouse can see and hear a piano being played, but believing is something else; it requires the concept of a piano, and understanding. Mice who hear pianos being played do not believe pianos are being played. | |
| From: Fred Dretske (Naturalizing the Mind [1997], §1.3) | |
| A reaction: Are we to say that when a mouse hears a piano it has no beliefs at all? Might not a belief involve images, so that a mouse calls up appropriate images from previous experiences, which are in a grey area on the edge of belief? |
| 5802 | Representations are in the head, but their content is not, as stories don't exist in their books [Dretske] |
| Full Idea: Representations are in the head, but their content is not; in this sense, the mind isn't in the head any more than stories (i.e. story contents) are in books. | |
| From: Fred Dretske (Naturalizing the Mind [1997], §1.6) | |
| A reaction: This is the final consequence of Putnam's idea that meanings ain't in the head. Intentionality is an extraordinary bridge between the brain and the external world. The ontology of stories, and musical compositions, is one philosophy's deepest problems. |
| 5809 | Some activities are performed better without consciousness of them [Dretske] |
| Full Idea: Some tasks (playing the piano, speaking foreign languages, playing fast sports) are best performed when the agent is largely unconscious of the details. | |
| From: Fred Dretske (Naturalizing the Mind [1997], Ch.4 n16) | |
| A reaction: A significant point, but it supports the evolutionary view, which is that what matters is success, and consciousness will switch on or off, whichever promotes the activity best. |
| 5808 | Qualia are just the properties objects are represented as having [Dretske] |
| Full Idea: The Representational Thesis of mind identifies the qualities of experience - qualia - with the properties objects are represented as having. | |
| From: Fred Dretske (Naturalizing the Mind [1997], §3.2) | |
| A reaction: This seems to challenge the distinction between primary and secondary qualities, of which I am very fond. Is 'looks beautiful' a property of an object? Is the feeling of anger a property of an object? Qualia are properties of brains? |
| 5803 | In a representational theory of mind, introspection is displaced perception [Dretske] |
| Full Idea: On a representational theory of the mind, introspection becomes an instance of displaced perception - knowledge of internal (mental) facts via an awareness of external (physical) objects. | |
| From: Fred Dretske (Naturalizing the Mind [1997], §2) | |
| A reaction: This sounds close to a behaviourist (e.g. Ryle) account of introspection, via observing one's own behaviour. The word 'displaced' is an easy one, concealing a multitude of questions. |
| 5807 | Introspection is the same as the experience one is introspecting [Dretske] |
| Full Idea: Introspection has no phenomenology or, if it does, it always has the same phenomenology as the experience one is introspecting. | |
| From: Fred Dretske (Naturalizing the Mind [1997], §2.4) | |
| A reaction: There is a difference between looking at a tree, and being aware of yourself looking at a tree. You can be faintly depressed, and then become aware that you are faintly depressed. He is nearly right. |
| 5805 | Introspection does not involve looking inwards [Dretske] |
| Full Idea: The 'problem' of introspection evaporates once one understands that it is not a process in which one looks inward. | |
| From: Fred Dretske (Naturalizing the Mind [1997], §2) | |
| A reaction: I take it that when we introspect we look at the contents of thoughts, which are representations of the external world, on the whole. But surely only the connections of those contents with memories can be seen inwardly? |
| 5804 | A representational theory of the mind is an externalist theory of the mind [Dretske] |
| Full Idea: A representational theory of the mind is an externalist theory of the mind. | |
| From: Fred Dretske (Naturalizing the Mind [1997], §2) | |
| A reaction: Presumably brain events bring the world into the mind, so the world must be mentioned in explaining the mind. Maybe 'externalism' sounds grand, but is stating the boringly obvious. Explanations of mind need no mention of external particulars. |
| 5800 | All mental facts are representation, which consists of informational functions [Dretske] |
| Full Idea: My thesis is that all mental facts are representational facts, and that all representational facts are facts about informational functions. | |
| From: Fred Dretske (Naturalizing the Mind [1997], Prol) | |
| A reaction: The first half of the thesis seems a bit difficult to disagree with, but that a fact is 'represented' may not be the essence of that fact. The biggest mystery is the content, not its representation. And everything is 'information' about everything else. |
| 3178 | A fast machine could pass all behavioural tests with a vast lookup table [Block, by Rey] |
| Full Idea: Ned Block proposes a machine (a 'blockhead') which could pass the Turing Test just by looking up responses in a vast look-up table. | |
| From: report of Ned Block (works [1984]) by Georges Rey - Contemporary Philosophy of Mind 5.3 | |
| A reaction: Once you suspected you were talking to a blockhead, I think you could catch it out in a Turing Test. How can the lookup table keep up to date with immediate experience? Ask it about your new poem. |
| 2705 | How can intuitionists distinguish universal convictions from local cultural ones? [Hare] |
| Full Idea: There are convictions which are common to most societies; but there are others which are not, and no way is given by intuitionists of telling which are the authoritative data. | |
| From: Richard M. Hare (Universal Prescriptivism [1991], p.454) | |
| A reaction: It seems unfair on intuitionists to say they haven't given a way to evaluate such things, given that they have offered intuition. The issue is what exactly they mean by 'intuition'. |
| 2712 | You can't use intuitions to decide which intuitions you should cultivate [Hare] |
| Full Idea: If it comes to deciding what intuitions and dispositions to cultivate, we cannot rely on the intuitions themselves, as intuitionists do. | |
| From: Richard M. Hare (Universal Prescriptivism [1991], p.461) | |
| A reaction: Makes intuitionists sound a bit dim. Surely Hume identifies dispositions (such as benevolence) which should be cultivated, because they self-evidently improve social life? |
| 2706 | Emotivists mistakenly think all disagreements are about facts, and so there are no moral reasons [Hare] |
| Full Idea: Emotivists concluded too hastily that because naturalism and intuitionism are false, you cannot reason about moral questions, because they assumed that the only questions you can reason about are factual ones. | |
| From: Richard M. Hare (Universal Prescriptivism [1991], p.455) | |
| A reaction: Personally I have a naturalistic view of ethics (based on successful functioning, as indicated by Aristotle), so not my prob. Why can't we reason about expressive emotions? We reason about art. |
| 2709 | Prescriptivism sees 'ought' statements as imperatives which are universalisable [Hare] |
| Full Idea: Universal prescriptivists hold that 'ought'-judgements are prescriptive like plain imperatives, but differ from them in being universalisable. | |
| From: Richard M. Hare (Universal Prescriptivism [1991], p.457) | |
| A reaction: Sounds a bit tautological. Which comes first, the normativity or the universalisability? |
| 2704 | If morality is just a natural or intuitive description, that leads to relativism [Hare] |
| Full Idea: Non-descriptivists (e.g. prescriptivists) reject descriptivism in its naturalist or intuitionist form, because they are both destined to collapse into relativism. | |
| From: Richard M. Hare (Universal Prescriptivism [1991], p.453) | |
| A reaction: I'm not clear from this why prescriptism would not also turn out to be relativist, if it includes evaluations along with facts. |
| 2703 | Descriptivism say ethical meaning is just truth-conditions; prescriptivism adds an evaluation [Hare] |
| Full Idea: Ethical descriptivism is the view that ethical sentence-meaning is wholly determined by truth-conditions. …Prescriptivists think there is a further element of meaning, which expresses prescriptions or evaluations or attitudes which we assent to. | |
| From: Richard M. Hare (Universal Prescriptivism [1991], p.452) | |
| A reaction: Not sure I understand either of these. If all meaning consists of truth-conditions, that will apply to ethics. If meaning includes evaluations, that will apply to non-ethics. |
| 2707 | If there can be contradictory prescriptions, then reasoning must be involved [Hare] |
| Full Idea: Prescriptivists claim that there are rules of reasoning which govern non-descriptive as well as descriptive speech acts. The standard example is possible logical inconsistency between contradictory prescriptions. | |
| From: Richard M. Hare (Universal Prescriptivism [1991], p.455) | |
| A reaction: The example doesn't seem very good. Inconsistency can appear in any area of thought, but that isn't enough to infer full 'rules of reasoning'. I could desire two incompatible crazy things. |
| 2708 | An 'ought' statement implies universal application [Hare] |
| Full Idea: In any 'ought' statement there is implicit a principle which says that the statement applies to all precisely similar situations. | |
| From: Richard M. Hare (Universal Prescriptivism [1991], p.456) | |
| A reaction: No two situations can ever be 'precisely' similar. Indeed, 'precisely similar' may be an oxymoron (at least for situations). Kantians presumably like this idea. |
| 2711 | Prescriptivism implies a commitment, but descriptivism doesn't [Hare] |
| Full Idea: Prescriptivists hold that moral judgements commit the speaker to motivations and actions, but non-moral facts by themselves do not do this. | |
| From: Richard M. Hare (Universal Prescriptivism [1991], p.459) | |
| A reaction: Surely hunger motivates to action? I suppose the key word is 'commit'. But lazy people are allowed to make moral judgements. |
| 2710 | Moral judgements must invoke some sort of principle [Hare] |
| Full Idea: To make moral judgements is implicitly to invoke some principle, however specific. | |
| From: Richard M. Hare (Universal Prescriptivism [1991], p.458) |
