13773 | For the truth you need Prodicus's fifty-drachma course, not his one-drachma course [Socrates] |
Full Idea: Socrates: If I'd attended Prodicus's fifty-drachma course, I could tell you the truth about names straightway, but as I've only heard the one-drachma course, I don't know the truth about it. | |
From: Socrates (reports of career [c.420 BCE]), quoted by Plato - Cratylus 384b |
7421 | A philosopher is one who cares about what other people care about [Socrates, by Foucault] |
Full Idea: Socrates asks people 'Are you caring for yourself?' He is the man who cares about the care of others; this is the particular position of the philosopher. | |
From: report of Socrates (reports of career [c.420 BCE]) by Michel Foucault - Ethics of the Concern for Self as Freedom p.287 | |
A reaction: Priests, politicians and psychiatrists also care quite intensely about the concerns of other people. Someone who was intensely self-absorbed with the critical task of getting their own beliefs right would count for me as a philosopher. |
18559 | Philosophy is empty if it does not in some way depend on matters of fact [Machery] |
Full Idea: Save, maybe, for purely formal (e.g. logical) theories, philosophical claims whose correctness does not depend, however indirectly, on matters of fact are empty: they are neither true nor false. | |
From: Edouard Machery (Doing Without Concepts [2009], Intro) | |
A reaction: I subscribe to this view. I'd even say that logic is empty if it is not answerable to the facts. The facts are nature, so this is a naturalistic manifesto. |
1649 | Socrates opened philosophy to all, but Plato confined moral enquiry to a tiny elite [Vlastos on Socrates] |
Full Idea: To confine, as Plato does in 'Republic' IV-VII, moral inquiry to a tiny elite, is to obliterate the Socratic vision which opens up the philosophic life to all. | |
From: comment on Socrates (reports of career [c.420 BCE]) by Gregory Vlastos - Socrates: Ironist and Moral Philosopher p.18 | |
A reaction: This doesn't mean that Plato is necessarily 'elitist'. It isn't elitist to point out that an activity is very difficult. |
5842 | Philosophical discussion involves dividing subject-matter into categories [Socrates, by Xenophon] |
Full Idea: Self-discipline and avoidance of pleasure makes people most capable of philosophical discussion, which is called 'discussion' (dialegesthai - sort out) because people divide their subject-matter into categories. | |
From: report of Socrates (reports of career [c.420 BCE]) by Xenophon - Memorabilia of Socrates 4.5.12 | |
A reaction: This could be the original slogan for analytical philosophy, as far as I am concerned. I don't think philosophy aims at complete and successful analysis (cf. Idea 2958), but at revealing the structure and interconnection of ideas. This is wisdom. |
648 | Socrates began the quest for something universal with his definitions, but he didn't make them separate [Socrates, by Aristotle] |
Full Idea: Socrates began the quest for something universal in addition to the radical flux of perceptible particulars, with his definitions. But he rightly understood that universals cannot be separated from particulars. | |
From: report of Socrates (reports of career [c.420 BCE]) by Aristotle - Metaphysics 1086b |
164 | It is legitimate to play the devil's advocate [Socrates] |
Full Idea: It is legitimate to play the devil's advocate. | |
From: Socrates (reports of career [c.420 BCE]), quoted by Plato - Phaedrus 272c |
1647 | In Socratic dialogue you must say what you believe, so unasserted premises are not debated [Vlastos on Socrates] |
Full Idea: Socrates' rule of "say only what you believe"….excluded debate on unasserted premises, thereby distinguishing Socratic from Zenonian and earlier dialectics. | |
From: comment on Socrates (reports of career [c.420 BCE]) by Gregory Vlastos - Socrates: Ironist and Moral Philosopher p.14 |
115 | Socrates was pleased if his mistakes were proved wrong [Socrates] |
Full Idea: Socrates: I'm happy to have a mistaken idea of mine proved wrong. | |
From: Socrates (reports of career [c.420 BCE]), quoted by Plato - Gorgias 458a |
22099 | The method of Socrates shows the student is discovering the truth within himself [Socrates, by Carlisle] |
Full Idea: Socrates tended to prefer the method of questioning, for this made it clear that the student was discovering the truth within himself. | |
From: report of Socrates (reports of career [c.420 BCE]) by Clare Carlisle - Kierkegaard: a guide for the perplexed 7 | |
A reaction: Sounds like it will only facilitate conceptual analysis, and excludes empirical knowledge. Can you say to Socrates 'I'll just google that'? |
5844 | Socrates always proceeded in argument by general agreement at each stage [Socrates, by Xenophon] |
Full Idea: When Socrates was setting out a detailed argument, he used to proceed by such stages as were generally agreed, because he thought that this was the infallible method of argument. | |
From: report of Socrates (reports of career [c.420 BCE]) by Xenophon - Memorabilia of Socrates 4.6.16 | |
A reaction: This sounds right, and shows how strongly Socrates perceived philosophy to be a group activity, of which I approve. It seems to me that philosophy is clearly a spoken subject before it is a written one. The lonely speculator comes much later. |
11389 | Socrates sought essences, which are the basis of formal logic [Socrates, by Aristotle] |
Full Idea: It is not surprising that Socrates sought essences. His project was to establish formal reasoning, of whose syllogisms essences are the foundations. | |
From: report of Socrates (reports of career [c.420 BCE]) by Aristotle - Metaphysics 1078b22 | |
A reaction: This seems to reinforce the definitional view of essences, since definitions seem to be at the centre of most of Socrates's quests. |
639 | Socrates developed definitions as the basis of syllogisms, and also inductive arguments [Socrates, by Aristotle] |
Full Idea: Socrates aimed to establish formal logic, of whose syllogisms essences are the foundations. He developed inductive arguments and also general definitions. | |
From: report of Socrates (reports of career [c.420 BCE]) by Aristotle - Metaphysics 1078b |
18564 | Do categories store causal knowledge, or typical properties, or knowledge of individuals? [Machery] |
Full Idea: Psychologists have attempted to determine whether a concept of a category stores some causal knowledge about the members, some knowledge about their typical properties, or some knowledge about specific members. | |
From: Edouard Machery (Doing Without Concepts [2009], 1.3.2) | |
A reaction: I take there to be a psychological process of 'generalisation', so that knowledge of individuals is not and need not be retained. I am dubious about entities called 'properties', so I will vote for causal (including perceptual) knowledge. |
18604 | Are quick and slow categorisation the same process, or quite different? [Machery] |
Full Idea: Are categorisation under time pressure and categorisation without time pressure ...two different cognitive competences? | |
From: Edouard Machery (Doing Without Concepts [2009], 5.1.1) | |
A reaction: This is a psychologist's question. Introspectively, they do seem to be rather different, as there is no time for theorising and explaining when you are just casting your eyes over the landscape. |
18573 | For each category of objects (such as 'dog') an individual seems to have several concepts [Machery] |
Full Idea: I contend that the best available evidence suggests that for each category of objects an individual typically has several concepts. For instance, instead of having a single concept of dog, an individual has in fact several concepts of dog. | |
From: Edouard Machery (Doing Without Concepts [2009], 3) | |
A reaction: Machery's book is a sustained defence of this hypothesis, with lots of examples from psychology. Any attempt by philosophers to give a neat and tidy account of categorisation looks doomed. |
18602 | A thing is classified if its features are likely to be generated by that category's causal laws [Machery] |
Full Idea: A to-be-classified object is considered a category member to the extent that its features were likely to have been generated by the category's causal laws. | |
From: Edouard Machery (Doing Without Concepts [2009], 4.4.4) | |
A reaction: [from Bob Rehder, psychologist, 2003] This is an account of categorisation which arises from the Theory Theory view of concepts, of which I am a fan. I love this idea, which slots neatly into the account I have been defending. Locke would like this. |
18565 | There may be ad hoc categories, such as the things to pack in your suitcase for a trip [Machery] |
Full Idea: There may be ad hoc categories, as when people think about the things to pack in a small suitcase for a trip abroad. | |
From: Edouard Machery (Doing Without Concepts [2009], 1.4.1) | |
A reaction: This seems to be obviously correct, though critics might say that 'category' is too grand a term for such a grouping. |
1652 | Socrates did not consider universals or definitions as having separate existence, but Plato made Forms of them [Socrates, by Aristotle] |
Full Idea: Socrates did not regard the universals or the objects of definitions as separate existents, while Plato did separate them, and called this sort of entity ideas/forms. | |
From: report of Socrates (reports of career [c.420 BCE]) by Aristotle - Metaphysics 1078b30 |
18570 | There may be several ways to individuate things like concepts [Machery] |
Full Idea: Philosophers have rarely explained why they believe that there is a single correct way of individuating concepts. Many entities can be legitimately individuated in several ways. | |
From: Edouard Machery (Doing Without Concepts [2009], 2.1.3) | |
A reaction: I cite this under 'individuation' because I think that is a very garbled concept. I agree with this point, even though I don't really know exactly what individuation is supposed to be. |
18614 | Vertical arguments say eliminate a term if it picks out different natural kinds in different theories [Machery] |
Full Idea: Vertical arguments for eliminativism of theoretical terms note that distinct types of generalisation do not line up with each other. ...It is argued that the theoretical term picks out more than one natural kind. | |
From: Edouard Machery (Doing Without Concepts [2009], 8.2.3) | |
A reaction: He mentions 'depression', as behavioural and cognitive; the former includes apes, and the latter doesn't. It is a nice principle for tidying up theories. |
18615 | Horizontal arguments say eliminate a term if it fails to pick out a natural kind [Machery] |
Full Idea: Horizontal arguments for eliminativism of theoretical terms say that some terms should be eliminated if they do not pick out a natural kind. | |
From: Edouard Machery (Doing Without Concepts [2009], 8.2.3) | |
A reaction: This is the one Machery likes, but I would say that it is less obvious than the 'vertical' version, since picking out a natural kind may not be the only job of a theoretical term. (p.238: Machery agrees!) |
18616 | If a term doesn't pick out a kind, keeping it may block improvements in classification [Machery] |
Full Idea: If a hypothesised natural kind term fails to pick out a natural kind, keeping this theoretical term is likely to prevent the development of a new classification system that would identify the relevant kinds. | |
From: Edouard Machery (Doing Without Concepts [2009], 8.2.3) | |
A reaction: I'm persuaded. This is why metaphysicians should stop talking about 'properties'. |
18609 | Psychologists use 'induction' as generalising a property from one category to another [Machery] |
Full Idea: Typically, psychologists use 'induction' to refer to the capacity to generalise a property from a category (the source) to another category (the target). | |
From: Edouard Machery (Doing Without Concepts [2009], 7.1.1) | |
A reaction: This is because psychologists are interested in the ongoing activities of thought. Philosophers step back a bit, to ask how the whole thing could get started. Philosophical induction has to start with individuals and single observations. |
18610 | 'Ampliative' induction infers that all members of a category have a feature found in some of them [Machery] |
Full Idea: Induction is 'ampliative' when it infers that all or most members of a category possess a property from the fact that some of its members have this property. | |
From: Edouard Machery (Doing Without Concepts [2009], 7.1.1) | |
A reaction: This sounds like a simple step in reasoning, but actually it is more like explanation, and will involve overall coherence and probability, rather than a direct conclusion. This invites sceptical questions. The last one observed may be the exception. |
6552 | You can only explain the qualities of large objects using entities which lack those qualities [Heisenberg] |
Full Idea: It is impossible to explain the manifest qualities of ordinary middle-sized objects except by tracing these back to the behaviour of entities which themselves no longer possess these qualities. | |
From: Werner Heisenberg (Ancient Thought in Modern Physics [1937], p.119), quoted by William Lycan - Consciousness 8.10 | |
A reaction: Compare the similar wonderful remark by Lucretius (Idea 5713). If we accept this as a general principle for all of nature (including us) - and I do - then it is silly to complain that consciousness isn't found in basic physics. |
1650 | For Socrates our soul, though hard to define, is our self [Vlastos on Socrates] |
Full Idea: For Socrates our soul is our self - whatever that might turn out to be. | |
From: comment on Socrates (reports of career [c.420 BCE]) by Gregory Vlastos - Socrates: Ironist and Moral Philosopher p.55 | |
A reaction: The problem with any broad claim like this is that we seem to be able to distinguish between essential and non-essential aspects of the self or of the soul. |
18562 | Connectionists cannot distinguish concept-memories from their background, or the processes [Machery] |
Full Idea: Connectionists typically do not distinguish between processes and memory stores, and, more importantly, it is unclear whether connectionists can draw a distinction between the knowledge stored in a concept and the background. | |
From: Edouard Machery (Doing Without Concepts [2009], 1.1) | |
A reaction: In other words connectionism fails to capture the structured nature of our thinking. There is an innate structure (which, say I, should mainly be seen as 'mental files'). |
18561 | We can identify a set of cognitive capacities which are 'higher order' [Machery] |
Full Idea: Categorization, deduction, induction, analogy-making, linguistic understanding, and planning - all of these are higher cognitive capacities. | |
From: Edouard Machery (Doing Without Concepts [2009], 1.1) | |
A reaction: His 'lower' competences are perceptual and motor. I say the entry to the higher competences are abstraction, idealisation and generalisation. If you can't do these (chimpanzees!) you will not be admitted. |
23252 | Socrates first proposed that we are run by mind or reason [Socrates, by Frede,M] |
Full Idea: It would seem that historically the decisive step was taken by Socrates in conceiving of human beings as being run by a mind or reason.. …He postulated an entity whose precision nature and function then was a matter of considerable debate. | |
From: report of Socrates (reports of career [c.420 BCE]) by Michael Frede - Intro to 'Rationality in Greek Thought' p.19 | |
A reaction: This is, for me, a rather revelatory idea. I am keen on the fact the animals make judgements which are true and false, and also that we exhibit rationality when walking across uneven ground. So pure rationality is a cultural construct! |
18574 | Concepts for categorisation and for induction may be quite different [Machery] |
Full Idea: In general, concepts that are used when we categorise and concepts that are used when we reason inductively could have little in common. | |
From: Edouard Machery (Doing Without Concepts [2009], 3.2.1) | |
A reaction: In the end he is going to reject concepts altogether, so he would say this. Friends of concepts would be very surprised if the mind were so uneconomical in its activities, given that induction seems to be up to its neck in categorisation. |
18588 | Concept theories aim at their knowledge, processes, format, acquisition, and location [Machery] |
Full Idea: A theory of concepts should determine the knowledge stored in them, and the cognitive processes that use concepts. Ideally it should also characterise their format, their acquisition, and (increasingly) localise them in the brain. | |
From: Edouard Machery (Doing Without Concepts [2009], 4) | |
A reaction: Machery reveals his dubious scientism in the requirement to localise them in the brain. That strikes me as entirely irrelevant to both philosophy and psychology. I want the format, acquisition and knowledge. |
18611 | We should abandon 'concept', and just use 'prototype', 'exemplar' and 'theory' [Machery] |
Full Idea: The notion of 'concept' ought to be eliminated from the theoretical vocabulary of psychology, and replaced by the notions of prototype, exemplar, and theory. | |
From: Edouard Machery (Doing Without Concepts [2009], 8) | |
A reaction: Machery's main thesis. I think similarly about 'property' in metaphysics. It embraces different ideas, and if we eliminated 'property' (and used predicate, class, fundamental power, complex power) we would do better. Psychologists have dropped 'memory'. |
18567 | In the philosophy of psychology, concepts are usually introduced as constituents of thoughts [Machery] |
Full Idea: In the philosophy of psychology, concepts are usually introduced as constituents, components, or parts of thoughts. | |
From: Edouard Machery (Doing Without Concepts [2009], 1.4.3) | |
A reaction: My instincts are against this. I take the fundamentals of concepts to be mental responses to distinct individual items in the world. Thought builds up from that. He says psychologists themselves don't see it this way. Influence of Frege. |
18569 | In philosophy theories of concepts explain how our propositional attitudes have content [Machery] |
Full Idea: A philosophical theory of concepts is a semantic theory for our propositional attitudes: it explains how our thoughts can have the content they have. | |
From: Edouard Machery (Doing Without Concepts [2009], 2.1.2) | |
A reaction: I suppose this is what I am interested in. I want to know in what way concepts form a bridge between content and world. I am more interested in the propositions, and less interested in our attitudes towards them. |
18563 | By 'concept' psychologists mean various sorts of representation or structure [Machery] |
Full Idea: Psychologists use 'concept' interchangeably with 'mental representation', 'category representation', 'knowledge representation', 'knowledge structure', 'semantic representation', and 'conceptual structures'. | |
From: Edouard Machery (Doing Without Concepts [2009], 1.1) | |
A reaction: [Machery gives references for each of these] Machery is moving in to attack these, but we look to psychologists to give some sort of account of what a concept might consist of, such that it could be implemented by neurons. |
18558 | Concept theorists examine their knowledge, format, processes, acquisition and location [Machery] |
Full Idea: Psychological theories of concepts try to describe the knowledge stored in concepts, the format of concepts, the cognitive processes that use the concepts, the acquisition of concepts, and the localization of concepts in the brain. | |
From: Edouard Machery (Doing Without Concepts [2009], Intro) | |
A reaction: I suppose it would the first two that are of central interest. What individuates a concept (its 'format') and what are the contents of a concept. The word 'stored' seems to imply a mental files view. |
18557 | Psychologists treat concepts as long-term knowledge bodies which lead to judgements [Machery] |
Full Idea: In psychology, concepts are characterized as those bodies of knowledge that are stored in long-term memory and used most higher cognitive competences when these processes result in judgements. | |
From: Edouard Machery (Doing Without Concepts [2009], Intro) | |
A reaction: Machery mounts an attack on this idea. I like the 'mental files' idea, where a concept starts as a label, and then acquires core knowledge, and then further information. The 'concept' is probably no more than a label, and minimal starter information. |
18560 | Psychologist treat concepts as categories [Machery] |
Full Idea: Psychologists often use 'concept' and 'category' interchangeably. | |
From: Edouard Machery (Doing Without Concepts [2009], 1.1) | |
A reaction: Well they shouldn't. Some concepts are no more than words, and don't categorise anything. Some things may be categorised by a complex set of concepts. |
18592 | The concepts OBJECT or AGENT may be innate [Machery] |
Full Idea: Several concepts, such as OBJECT or AGENT, may be innate. | |
From: Edouard Machery (Doing Without Concepts [2009], 4.1.4) | |
A reaction: It is one thing to say that we respond to objects and agents, and another to say that we have those 'concepts'. Presumably birds, and even bees, have to relate to similar features. Add PROCESS? |
18584 | One hybrid theory combines a core definition with a prototype for identification [Machery] |
Full Idea: One hybrid theory of concepts says they have both a core and an identification procedure. The core is a definition (necessary and sufficient conditions), while the identification procedure consists of a prototype (the properties typical of a category). | |
From: Edouard Machery (Doing Without Concepts [2009], 3.3.1) | |
A reaction: This combines the classical and prototype theories of concepts. I like it because it fits the idea of 'mental files' nicely (see Recanati). If concepts are files (as in a database) they will have aspects like labels, basic info, and further details. |
18585 | Heterogeneous concepts might have conflicting judgements, where hybrid theories will not [Machery] |
Full Idea: The Heterogeneity Hypothesis, but not the hybrid theory of concepts, predicts that the coreferential bodies of knowledge it posits will occasionally lead to conflicting outcomes, such as inconsistent judgements. | |
From: Edouard Machery (Doing Without Concepts [2009], 3.3.2) | |
A reaction: Machery's book champions the Heterogeneous Hypothesis. Hybrid views say the aspects of a concept are integrated, but Heterogeneity says there are separate processes. My preferred 'file' approach would favour integration. |
18578 | Concepts as definitions was rejected, and concepts as prototypes, exemplars or theories proposed [Machery] |
Full Idea: Since the rejection of the classical theory of concepts (that they are definitions), three paradigms have successively emerged in the psychology of concepts: the prototype paradigm, the exemplar paradigm, and the theory paradigm. | |
From: Edouard Machery (Doing Without Concepts [2009], 4) | |
A reaction: I am becoming a fan of the 'theory theory' proposal, because the concepts centre around what explains the phenomenon, which fits my explanatory account of essentialism. Not that it's right because it agrees with me, of course..... |
18566 | Concepts should contain working memory, not long-term, because they control behaviour [Machery] |
Full Idea: We ought to reserve the term 'concept' for the bodies of knowledge in working memory, and not for our knowledge of long-term memory, because the former, and not the latter, 'control behaviour'. | |
From: Edouard Machery (Doing Without Concepts [2009], 1.4.1) | |
A reaction: [He cites the psychologist Barsalou 1993] Some more theoretical concepts can only be recalled with difficulty, and control our theorising rather than our behaviour. But we act on some theories, so there is no clear borderline. |
18575 | The concepts for a class typically include prototypes, and exemplars, and theories [Machery] |
Full Idea: Across domains (such as biology and psychology) classes of physical objects, substances and events are typically represented by a prototype, by a set of exemplars, and by a theory. | |
From: Edouard Machery (Doing Without Concepts [2009], 3.2.3) | |
A reaction: In other words he thinks that all of the major psychological theories of concepts are partially correct, and he argues for extensive pluralism in the true picture. Bad news for neat philosophy, but real life is a right old mess. |
18583 | Many categories don't seem to have a definition [Machery] |
Full Idea: For many categories there is simply no definition to learn (such as Wittgenstein's example of a 'game'). | |
From: Edouard Machery (Doing Without Concepts [2009], 4.1.4) |
18591 | Classical theory can't explain facts like typical examples being categorised quicker [Machery] |
Full Idea: The nail in the coffin of the classical theory is its lack of explanatory power. For example it doesn't explain the fact that typical x's are categorised more quickly and more reliably than atypical x's. | |
From: Edouard Machery (Doing Without Concepts [2009], 4.1.3) | |
A reaction: [He cites Rosch and Mervis: 1975:ch 5] This research launched the 'prototype' theory, which has since been challenged by the 'exemplar' and 'theory theory' rivals (and neo-empiricism, and idealisation). |
18590 | Classical theory implies variety in processing times, but this does not generally occur [Machery] |
Full Idea: If a concept is defined by means of another, such as MURDER by means of KILL, then processing the former concept should take longer in the classical theory, but several experiments show that this is not the case. | |
From: Edouard Machery (Doing Without Concepts [2009], 4.1.3) | |
A reaction: For the philosopher there is no escaping the findings of neuroscience when it comes to the study of concepts. This invites the question of the role, if any, of philosophy. I take philosophy to concern the big picture, or it is nothing. |
18594 | Knowing typical properties of things is especially useful in induction [Machery] |
Full Idea: Knowing which properties are typical of a class is particularly useful when you have to draw inductions about the members of a class. | |
From: Edouard Machery (Doing Without Concepts [2009], 4.2.1) |
18593 | The term 'prototype' is used for both typical category members, and the representation [Machery] |
Full Idea: The term 'prototype' is used ambiguously to designate the most typical members of a category, and the representation of a category. (I use the term in the second sense). | |
From: Edouard Machery (Doing Without Concepts [2009], 4.2.1 n25) |
18595 | Prototype theories are based on computation of similarities with the prototype [Machery] |
Full Idea: The most important property of prototype theories is that cognitive processes are assumed to involve the computation of the similarity between prototypes and other representations. | |
From: Edouard Machery (Doing Without Concepts [2009], 4.2.3) | |
A reaction: [He cites J.A.Hampton 1998, 2006] This presumably suits theories of the mind as largely computational (e.g. Fodor's account, based on the Turing machine). |
18596 | Prototype theorists don't tell us how we select the appropriate prototype [Machery] |
Full Idea: We are typically not told how prototypes are selected, that is, what determines whether a specific prototype is retrieved from memory in order to be involved in the categorisation process. | |
From: Edouard Machery (Doing Without Concepts [2009], 4.2.4) | |
A reaction: One of the aims of this database is to make people aware of ideas that people have already thought of. This one was spotted 2,400 years ago. It's the Third Man problem. How do you even start to think about a particular thing? |
18603 | Maybe concepts are not the typical properties, but the ideal properties [Machery] |
Full Idea: Barsalou (1983,1985) introduced the idea of ideals instead of prototypes. An ideal is a body of knowledge about the properties a thing should possess (rather than its typical actual properties). ... A 'bully' might be perfect, rather than typical. | |
From: Edouard Machery (Doing Without Concepts [2009], 4.5.3) | |
A reaction: [compressed] Machery offers this as an interesting minor variant, with little experimental support. I take idealisation to be one of the three key mental operations that enable us to think about the world (along with abstraction and generalisation). |
18605 | It is more efficient to remember the prototype, than repeatedly create it from exemplars [Machery] |
Full Idea: Instead of regularly producing a prototype out of the exemplars stored in long-term memory, it seems more efficient to extract a prototype from category members during concept learning and to use this prototype when needed. | |
From: Edouard Machery (Doing Without Concepts [2009], 6.3.2) | |
A reaction: [This is a critique of Barsalou's on-the-fly proposal for prototypes] If the exemplar theory is right, then some sort of summary must occur when faced with a new instance. So this thought favours prototypes against exemplars. |
18606 | The prototype view predicts that typical members are easier to categorise [Machery] |
Full Idea: The prototype paradigm of concepts makes the strong prediction that typical members should be easier to categorise than atypical members. | |
From: Edouard Machery (Doing Without Concepts [2009], 6.4.1) | |
A reaction: This is why philosophers should approach the topic of concepts with caution. Clearly empirical testing is going to settle this matter, not abstract theorising. |
18597 | Concepts as exemplars are based on the knowledge of properties of each particular [Machery] |
Full Idea: The exemplar paradigm of concepts is built around the idea that concepts are sets of exemplars. In turn, an exemplar is a body of knowledge about the properties believed to be possessed by a particular member of a class. | |
From: Edouard Machery (Doing Without Concepts [2009], 4.3.1) | |
A reaction: I like the fact that this theory is rooted in particulars, where the prototype theory doesn't seem to say much about how prototypes are derived. But you have to do more than just contemplate a bunch of exemplars. |
18598 | Exemplar theories need to explain how the relevant properties are selected from a multitude of them [Machery] |
Full Idea: Exemplar theories have a selection problem. Given that individuals have an infinite number of properties, they need to explain why exemplars represent such and such properties, instead of others. | |
From: Edouard Machery (Doing Without Concepts [2009], 4.3.1) | |
A reaction: I have the impression that this idea rests on the 'abundant' view of properties - that every true predicate embodies a property. A sparse view of properties might give a particular quite a restricted set of properties. |
18599 | In practice, known examples take priority over the rest of the set of exemplars [Machery] |
Full Idea: An object that is extremely similar to a specific known category member, but only moderately similar to others, is more likely to be categorised as a category member than an object that is moderately similar to most known category members. | |
From: Edouard Machery (Doing Without Concepts [2009], 4.3.3) | |
A reaction: This research finding is a problem for the Exemplar Theory, in which all the exemplars have equal status. It is even a problem for the Prototype Theory, since the known member may not be like the prototype. |
18587 | The theory account is sometimes labelled as 'knowledge' or 'explanation' in approach [Machery] |
Full Idea: The theory paradigm is sometimes called 'the knowledge approach' (Murphy 2002) or 'explanation-based views' (Komatsu 1992). | |
From: Edouard Machery (Doing Without Concepts [2009], 4) | |
A reaction: The word 'explanation' is music to my ears, so I am immediately sympathetic to the theory theory of concepts, even if it falls at the final hurdle. |
18600 | Theory Theory says category concepts are knowledge stores explaining membership [Machery] |
Full Idea: According to theory theorists, a concept of a category stores some knowledge that can explain the properties of the category members. | |
From: Edouard Machery (Doing Without Concepts [2009], 4.4.1) | |
A reaction: This is the account of essentialism which I defended in my PhD thesis. So naturally I embrace a theory of the nature of concepts which precisely dovetails with my view. I take explanation to be the central concept in metaphysics. |
18601 | Theory Theory says concepts are explanatory knowledge, and concepts form domains [Machery] |
Full Idea: The two core ideas of the Theory Theory are that concepts are bodies of knowledge that underlie explanation, where explanation rests on folk examples, and concepts are organised in domains which use similar knowledge. | |
From: Edouard Machery (Doing Without Concepts [2009], 4.4.1) | |
A reaction: Folk explanation is opposed to scientific explanation, as expounded by Hempel etc. This sounds better and better, since the domains reflect the structure of reality. Machery defends Theory Theory as part of the right answer, but it's my favourite bit. |
18607 | Theory theorists rely on best explanation, rather than on similarities [Machery] |
Full Idea: Theory theorists deny that categorisation depends on similarity; they often propose that categorisation involves some kind of inference to the best explanation. | |
From: Edouard Machery (Doing Without Concepts [2009], 6.5.1) | |
A reaction: Love it. Any theory of concepts should, in my view, be continuous with a plausible account of animal minds, and best explanations are not their strong suit. Maybe its explanations for slow categorising, and something else when it's quick. |
18608 | If categorisation is not by similarity, it seems to rely on what properties things might have [Machery] |
Full Idea: It seems that when subjects are not categorising by similarity, they are relying on what properties objects can and cannot have - that is, on some modal knowledge. | |
From: Edouard Machery (Doing Without Concepts [2009], 6.5.1) | |
A reaction: I would call this essentialist categorisation, based on the inner causal powers which generate the modal profile of the thing. We categorise bullets and nails very differently, because of their modal profiles. |
18577 | The word 'grandmother' may be two concepts, with a prototype and a definition [Machery] |
Full Idea: If a prototype of grandmothers represents them as grey-haired old women, and a definition of grandmothers represents them as being necessarily the mother of a parent ....we may fail to recognise that 'grandmother' represents two distinct concepts. | |
From: Edouard Machery (Doing Without Concepts [2009], 3.3.4) | |
A reaction: He is referring to two distinct theories about what a concept is. He argues that both theories apply, so words do indeed represent several different concepts. Nice example. |
18589 | For behaviourists concepts are dispositions to link category members to names [Machery] |
Full Idea: Behaviourists identified concepts with a mere disposition to associate category members with a given name. | |
From: Edouard Machery (Doing Without Concepts [2009], 4.1.1) | |
A reaction: This is one reason why the word 'disposition' triggers alarm bells in the immediately post-behaviourist generation of philosophers. The proposal is far too linguistic in character. |
18612 | Americans are more inclined to refer causally than the Chinese are [Machery] |
Full Idea: Tests suggest that American subjects were significantly more likely than Chinese subjects to have intuitions in line with causal-historical theories of reference. | |
From: Edouard Machery (Doing Without Concepts [2009], 8.1.3) | |
A reaction: This is an example of 'experimental philosophy' in action (of which Machery is a champion). The underlying idea is that Americans are generally more disposed to think causally than the Chinese are. So more scientific? What do the Hopi do? |
195 | No one willingly commits an evil or base act [Socrates] |
Full Idea: I am fairly certain that no wise man believes anyone sins willingly or willingly perpetrates any evil or base act. | |
From: Socrates (reports of career [c.420 BCE]), quoted by Plato - Protagoras 345e |
5843 | People do what they think they should do, and only ever do what they think they should do [Socrates, by Xenophon] |
Full Idea: There is no one who knows what they ought to do, but thinks that they ought not to do it, and no one does anything other than what they think they ought to do. | |
From: report of Socrates (reports of career [c.420 BCE]) by Xenophon - Memorabilia of Socrates 4.6.6 | |
A reaction: This is Socrates' well-known rejection of the possibility of weakness of will (akrasia - lit. 'lack of control'). Aristotle disagreed, and so does almost everyone else. Modern smokers seem to exhibit akrasia. I have some sympathy with Socrates. |
5253 | Socrates was shocked by the idea of akrasia, but observation shows that it happens [Aristotle on Socrates] |
Full Idea: Socrates thought it a shocking idea that when a man actually has knowledge in him something else should overmaster it, ..but this is glaringly inconsistent with the observed facts. | |
From: comment on Socrates (reports of career [c.420 BCE]) by Aristotle - Nicomachean Ethics 1145b24 | |
A reaction: Aristotle seems very confident, but it is not at all clear (even to the agent) what is going on when apparent weakness of will occurs (e.g. breaking a diet). What exactly does the agent believe at the moment of weakness? |
1653 | Socrates did not accept the tripartite soul (which permits akrasia) [Vlastos on Socrates] |
Full Idea: Xenophon indirectly indicates that he does not associate Socrates in any way with the tripartite psychology of the 'Republic', for within that theory akrasia would be all too possible. | |
From: comment on Socrates (reports of career [c.420 BCE]) by Gregory Vlastos - Socrates: Ironist and Moral Philosopher p.102 |
199 | The common belief is that people can know the best without acting on it [Socrates] |
Full Idea: Most people think there are many who recognise the best but are unwilling to act on it. | |
From: Socrates (reports of career [c.420 BCE]), quoted by Plato - Protagoras 352d |
5839 | For Socrates, wisdom and prudence were the same thing [Socrates, by Xenophon] |
Full Idea: Socrates did not distinguish wisdom from prudence, but judged that the man who recognises and puts into practice what is truly good, and the man who knows and guards against what is disgraceful, are both wise and prudent. | |
From: report of Socrates (reports of career [c.420 BCE]) by Xenophon - Memorabilia of Socrates 3.9.3 | |
A reaction: Compare Aristotle, who separates them, claiming that prudence is essential for moral virtue, but wisdom is pursued at a different level, closer to the gods than to society. |
5867 | For Socrates, virtues are forms of knowledge, so knowing justice produces justice [Socrates, by Aristotle] |
Full Idea: Socrates thought that the virtues were all forms of knowledge, and therefore once a man knew justice, he would be a just man. | |
From: report of Socrates (reports of career [c.420 BCE]) by Aristotle - Eudemian Ethics 1216b07 | |
A reaction: The clearest possible statement of Socrates' intellectualism. Aristotle rejected the Socrates view, but I find it sympathetic. Smokers who don't want to die seem to be in denial. To see the victims is to condemn the crime. |
5069 | Socrates was the first to base ethics upon reason, and use reason to explain it [Taylor,R on Socrates] |
Full Idea: Socrates was the first significant thinker to try basing ethics upon reason, and to try uncovering its natural principles solely by the use of reason. | |
From: comment on Socrates (reports of career [c.420 BCE]) by Richard Taylor - Virtue Ethics: an Introduction Ch.7 | |
A reaction: Interesting. It seems to me that Socrates overemphasised reason, presumably because it was a novelty. Hence his view that akrasia is impossible, and that virtue is simply knowledge. Maybe action is not just rational, but moral action is. |
5836 | All human virtues are increased by study and practice [Socrates, by Xenophon] |
Full Idea: If you consider the virtues that are recognised among human beings, you will find that they are all increased by study and practice. | |
From: report of Socrates (reports of career [c.420 BCE]) by Xenophon - Memorabilia of Socrates 2.6.41 | |
A reaction: 'Study' is the intellectualist part of this remark; the reference to 'practice' fits with Aristotle view that virtue is largely a matter of good habits. The next question would be how theoretical the studies should be. Philosophy, or newspapers? |
5840 | The wise perform good actions, and people fail to be good without wisdom [Socrates, by Xenophon] |
Full Idea: It is the wise who perform truly good actions, and those who are not wise cannot, and, if they try to, fail. | |
From: report of Socrates (reports of career [c.420 BCE]) by Xenophon - Memorabilia of Socrates 3.9.6 | |
A reaction: The essence of Socrates' intellectualism, with which Aristotle firmly disagreed (when he assert that only practical reason was needed for virtuous actions, rather than wisdom or theory). Personally I side more with Socrates than with Aristotle on this. |
185 | Socrates despised good looks [Socrates, by Plato] |
Full Idea: Socrates despises good looks to an almost inconceivable extent. | |
From: report of Socrates (reports of career [c.420 BCE]) by Plato - The Symposium 216e |
5070 | Socrates conservatively assumed that Athenian conventions were natural and true [Taylor,R on Socrates] |
Full Idea: Socrates' moral philosophy was essentially conservative. He assumed that the principles the Athenians honoured were true and natural, so there was little possibility of conflict between nature and convention in his thinking. | |
From: comment on Socrates (reports of career [c.420 BCE]) by Richard Taylor - Virtue Ethics: an Introduction Ch.8 | |
A reaction: Taylor contrasts Socrates with Callicles, who claims that conventions oppose nature. This fits with Nietzsche's discontent with Socrates, as the person who endorses conventional good and evil, thus constraining the possibilities of human nature. |
5838 | A well-made dung basket is fine, and a badly-made gold shield is base, because of function [Socrates, by Xenophon] |
Full Idea: A dung-basket is fine, and a golden shield contemptible, if the one is finely and the other badly constructed for carrying out its function. | |
From: report of Socrates (reports of career [c.420 BCE]) by Xenophon - Memorabilia of Socrates 3.8.6 | |
A reaction: This is the basis of a key idea in Aristotle, that virtue (or excellence) arises directly from function. I think it is the most important idea in virtue theory, and seems to have struck most Greeks as being self-evident. |
5837 | Things are both good and fine by the same standard [Socrates, by Xenophon] |
Full Idea: Things are always both good and fine by the same standard. | |
From: report of Socrates (reports of career [c.420 BCE]) by Xenophon - Memorabilia of Socrates 3.8.5 | |
A reaction: This begs many questions, but perhaps it leads to what we call intuitionism, which is an instant ability is perceive a fine action (even in an enemy). This leads to the rather decadent view that the aim of life is the production of beauty. |
3017 | The only good is knowledge, and the only evil is ignorance [Socrates, by Diog. Laertius] |
Full Idea: There is only one good, namely knowledge, and there is only one evil, namely ignorance. | |
From: report of Socrates (reports of career [c.420 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.4.14 | |
A reaction: Ignorance of how to commit evil sounds quite good. |
1646 | Socrates was the first to put 'eudaimonia' at the centre of ethics [Socrates, by Vlastos] |
Full Idea: Socrates' true place in the development of Greek thought is that he is the first to establish the eudaimonist foundation of ethical theory, which became the foundation of the schools which sprang up around him. | |
From: report of Socrates (reports of career [c.420 BCE]) by Gregory Vlastos - Socrates: Ironist and Moral Philosopher p.10 | |
A reaction: I suspect that he was the first to fully articulate a widely held Greek belief. The only ethical question that they asked was about the nature of a good human life. |
1663 | By 'areté' Socrates means just what we mean by moral virtue [Vlastos on Socrates] |
Full Idea: Socrates uses the word 'areté' to mean precisely what we mean by moral virtue. | |
From: comment on Socrates (reports of career [c.420 BCE]) by Gregory Vlastos - Socrates: Ironist and Moral Philosopher p.200 |
4323 | Socrates is torn between intellectual virtue, which is united and teachable, and natural virtue, which isn't [PG on Socrates] |
Full Idea: Socrates worries about the unity and teachability of virtue because he is torn between virtue as intellectual (unified and teachable) and virtue as natural (plural and unteachable). | |
From: comment on Socrates (reports of career [c.420 BCE]) by PG - Db (ideas) | |
A reaction: Admittedly virtue could be natural but still unified and teachable, but Socrates clearly had a dilemma, and this seems to make sense of it. |
8003 | Socrates agrees that virtue is teachable, but then denies that there are teachers [Socrates, by MacIntyre] |
Full Idea: Socrates' great point of agreement with the sophists is his acceptance of the thesis that areté is teachable. But paradoxically he denies that there are teachers. | |
From: report of Socrates (reports of career [c.420 BCE]) by Alasdair MacIntyre - A Short History of Ethics Ch.3 | |
A reaction: This is part of Socrates's presentation of himself as 'not worthy'. Virtue would be teachable, if only anyone knew what it was. He's wrong. Lots of people have a pretty good idea of virtue, and could teach it. The problem is in the pupils. |
126 | We should ask what sort of people we want to be [Socrates] |
Full Idea: Socrates: What sort of person should one be? | |
From: Socrates (reports of career [c.420 BCE]), quoted by Plato - Gorgias 487e |
4111 | Socrates believed that basically there is only one virtue, the power of right judgement [Socrates, by Williams,B] |
Full Idea: Socrates believed that basically there is only one virtue, the power of right judgement. | |
From: report of Socrates (reports of career [c.420 BCE]) by Bernard Williams - Ethics and the Limits of Philosophy Ch.1 | |
A reaction: Which links with Aristotle's high place for 'phronesis' (prudence?). The essence of Socrates' intellectualism. Robots and saints make very different judgements, though. |
7808 | Socrates made the civic values of justice and friendship paramount [Socrates, by Grayling] |
Full Idea: In Socrates' thought, the expressly civic values of justice and friendship became paramount. | |
From: report of Socrates (reports of career [c.420 BCE]) by A.C. Grayling - What is Good? Ch.2 | |
A reaction: This is the key move in ancient ethics, away from heroism, and towards the standard Aristotelian social virtues. I say this is the essence of what we call morality, and the only one which can be given a decent foundational justification (social health). |
23907 | Courage is scientific knowledge [Socrates, by Aristotle] |
Full Idea: Socrates thought that courage is scientific knowledge. | |
From: report of Socrates (reports of career [c.420 BCE]) by Aristotle - Eudemian Ethics 1230a06 | |
A reaction: Aristotle himself says that reason produces courage, but he also says it arises from natural youthful spirits. I favour the view that there is a strong rational component in true courage. |
7585 | Socrates emphasises that the knower is an existing individual, with existence his main task [Socrates, by Kierkegaard] |
Full Idea: The infinite merit of the Socratic position was precisely to accentuate the fact that the knower is an existing individual, and that the task of existing is his essential task. | |
From: report of Socrates (reports of career [c.420 BCE]) by Søren Kierkegaard - Concluding Unscientific Postscript 'Inwardness' | |
A reaction: Always claim Socrates as the first spokesman for your movement! It is true that Socrates is always demanding the views of his interlocutors, and not just abstract theories. See Idea 1647. |
5841 | Obedience to the law gives the best life, and success in war [Socrates, by Xenophon] |
Full Idea: A city in which the people are most obedient to the laws has the best life in time of peace and is irresistible in war. | |
From: report of Socrates (reports of career [c.420 BCE]) by Xenophon - Memorabilia of Socrates 4.4.15 | |
A reaction: This is a conservative view, with the obvious problem case of bad laws, but in general it seems to me clearly right. This is why it is so vital that nothing should be done to bring the law into disrepute, such as petty legislation or prosecution. |
1661 | Socrates was the first to grasp that a cruelty is not justified by another cruelty [Vlastos on Socrates] |
Full Idea: Socrates was the first Greek to grasp the truth that if someone has done a nasty thing to me, this does not give the slightest moral justification for doing anything nasty to him. | |
From: comment on Socrates (reports of career [c.420 BCE]) by Gregory Vlastos - Socrates: Ironist and Moral Philosopher p.190 |
5846 | A lover using force is a villain, but a seducer is much worse, because he corrupts character [Socrates, by Xenophon] |
Full Idea: The fact that a lover uses not force but persuasion makes him more detestable, because a lover who uses force proves himself a villain, but one who uses persuasion ruins the character of the one who consents. | |
From: report of Socrates (reports of career [c.420 BCE]) by Xenophon - Symposium 8.20 | |
A reaction: A footnote says that this distinction was enshrined in Athenian law, where seduction was worse than rape. This is a startling and interest contrast to the modern view, which enshrines rights and freedoms, and says seduction is usually no crime at all. |
18613 | Artifacts can be natural kinds, when they are the object of historical enquiry [Machery] |
Full Idea: Some artifacts are the objects of inquiry in the social sciences ...such as prehistoric tools ...and hence, artifacts are bona fide natural kinds. | |
From: Edouard Machery (Doing Without Concepts [2009], 8.2.1) | |
A reaction: Presumably if a bird's nest can be a natural kind, then so can a flint axe, but then so can a mobile phone, for an urban anthropologist. 'Natural' is, to put it mildly, a tricky word. |
1657 | Socrates holds that right reason entails virtue, and this must also apply to the gods [Vlastos on Socrates] |
Full Idea: It is essential to Socrates' rationalist programme in theology to assume that the entailment of virtue by wisdom binds gods no less than men. He would not tolerate one moral standard for me and another for gods. | |
From: comment on Socrates (reports of career [c.420 BCE]) by Gregory Vlastos - Socrates: Ironist and Moral Philosopher p.164 |
1662 | A new concept of God as unswerving goodness emerges from Socrates' commitment to virtue [Vlastos on Socrates] |
Full Idea: Undeviating beneficent goodness guides Socrates' thought so deeply that he applies it even to the deity; he projects a new concept of god as a being that can cause only good, never evil. | |
From: comment on Socrates (reports of career [c.420 BCE]) by Gregory Vlastos - Socrates: Ironist and Moral Philosopher p.197 |
