| 3811 | Entailment and validity are relations, but inference is a human activity [Searle] |
| Full Idea: We must distinguish between entailment and validity as logical relations on the one hand, and inferring as a voluntary human activity on the other. | |
| From: John Searle (Rationality in Action [2001], Ch.1.II) |
| 3822 | Theory involves accepting conclusions, and so is a special case of practical reason [Searle] |
| Full Idea: Theoretical reason is typically a matter of accepting a conclusion or hypothesis on the basis of argument or evidence, and is thus a special case of practical reason. | |
| From: John Searle (Rationality in Action [2001], Ch.3.VII) |
| 3806 | Rationality is built into the intentionality of the mind, and its means of expression [Searle] |
| Full Idea: Constraints of rationality are built into the structure of mind and language, specifically into the structure of intentionality and speech acts. | |
| From: John Searle (Rationality in Action [2001], Int xiv) |
| 3812 | Rationality is the way we coordinate our intentionality [Searle] |
| Full Idea: The constraints of rationality ought to be thought of adverbially; they are a matter of the way in which we coordinate our intentionality. | |
| From: John Searle (Rationality in Action [2001], Ch.1.II) |
| 3809 | If complex logic requires rules, then so does basic logic [Searle] |
| Full Idea: If you think you need a rule to infer q from 'p and (if p then q)', then you would also need a rule to infer p from p. | |
| From: John Searle (Rationality in Action [2001], Ch.1.II) |
| 3810 | In real reasoning semantics gives validity, not syntax [Searle] |
| Full Idea: In real-life reasoning it is the semantic content that guarantees the validity of the inference, not the syntactical rule. | |
| From: John Searle (Rationality in Action [2001], Ch.1.II) |
| 3841 | Users of 'supervenience' blur its causal and constitutive meanings [Searle] |
| Full Idea: I am no fan of the concept of supervenience. Its uncritical use is a sign of philosophical confusion, because the concept oscillates between causal supervenience and constitutive supervenience. | |
| From: John Searle (Rationality in Action [2001], Ch.9 n5) | |
| A reaction: I don't see why you shouldn't assert the supervenience of one thing on another, while saying that you are not sure whether it is causal or constitutive. The confusion seems to me to be in understandings of the causal version. |
| 17954 | Essence is a thing's necessities, but what about its possibilities (which may not be realised)? [Vetter] |
| Full Idea: Essence is, as it were, necessity rooted in things, ...but how about possibility rooted in things? ...Having the potential to Φ, unlike being essentially Φ, does not entail being actually Φ. | |
| From: Barbara Vetter (Essence and Potentiality [2010], §2) | |
| A reaction: To me this invites the question 'what is it about the entity which endows it with its rooted possibilities?' A thing has possibilities because it has a certain nature (at a given time). |
| 16083 | Aristotelian matter seriously threatens the intrinsic unity and substantiality of its object [Gill,ML] |
| Full Idea: On the interpretation of Aristotelian matter that I shall propose, matter seriously threatens the intrinsic unity, and hence the substantiality, of the object to which it contributes. | |
| From: Mary Louise Gill (Aristotle on Substance [1989], Intro) | |
| A reaction: Presumably the thought is that if an object is form+matter (hylomorphism), then forms are essentially unified, but matter is essentially unified and sloppy. |
| 17953 | Real definition fits abstracta, but not individual concrete objects like Socrates [Vetter] |
| Full Idea: I can understand the notion of real definition as applying to (some) abstact entities, but I have no idea how to apply it to a concrete object such as Socrates or myself. | |
| From: Barbara Vetter (Essence and Potentiality [2010], §1) | |
| A reaction: She is objecting to Kit Fine's account of essence, which is meant to be clearer than the normal account of essences based on necessities. Aristotle implies that definitions get fuzzy when you reach the level of the individual. |
| 17952 | Modal accounts make essence less mysterious, by basing them on the clearer necessity [Vetter] |
| Full Idea: The modal account was meant, I take it, to make the notion of essence less mysterious by basing it on the supposedly better understood notion of necessity. | |
| From: Barbara Vetter (Essence and Potentiality [2010], §1) |
| 17959 | Metaphysical necessity is even more deeply empirical than Kripke has argued [Vetter] |
| Full Idea: We support the views of metaphysical modality on which metaphysical necessity is an even more deeply empirical matter than Kripke has argued. | |
| From: Barbara Vetter (Essence and Potentiality [2010], p.2) | |
| A reaction: [co-author E. Viebahn] This seems to pinpoint the spirit of scientific essentialism. She cites Bird and Shoemaker. If it is empirical, doesn't that make it a matter of epistemology, and hence further from absolute necessity? |
| 17955 | Possible worlds allow us to talk about degrees of possibility [Vetter] |
| Full Idea: The apparatus of possible worlds affords greater expressive power than mere talk of possibility and necessity. In particular, possible worlds talk allows us to introduce degrees of possibility. | |
| From: Barbara Vetter (Essence and Potentiality [2010], §3) | |
| A reaction: A nice feature, but I'm not sure that either the proportion of possible worlds or the closeness of possible worlds captures what we actually mean by a certain degree of possibility. There is 'accidental closeness', or absence of contingency. See Vetter. |
| 17957 | Maybe possibility is constituted by potentiality [Vetter] |
| Full Idea: We should look at the claim that possibility is constituted by potentiality. | |
| From: Barbara Vetter (Essence and Potentiality [2010], §4) | |
| A reaction: A problem that comes to mind is possibilities arising from coincidence. The whole of reality must be described, to capture all the possibilities for a particular thing. So potentialities of what? Nice thought, though. |
| 17958 | The apparently metaphysically possible may only be epistemically possible [Vetter] |
| Full Idea: Some of what metaphysicians take to be metaphysically possible turns out to be only epistemically possible. | |
| From: Barbara Vetter (Essence and Potentiality [2010], §4) | |
| A reaction: A nice clear expression of the increasingly common view that conceivability may be a limited way to grasp possibility. |
| 17956 | Closeness of worlds should be determined by the intrinsic nature of relevant objects [Vetter] |
| Full Idea: The closeness of possible worlds should be determined by similarity in the intrinsic constitution of whatever object it is whose potentialities are at issue. | |
| From: Barbara Vetter (Essence and Potentiality [2010], §3) | |
| A reaction: Nice thought. This seems to be the essentialist approach to possible worlds, but it makes the natures of the objects more fundamental than the framework of the worlds. She demurs because there are also extrinsic potentialities. |
| 3833 | A belief is a commitment to truth [Searle] |
| Full Idea: A belief is a commitment to truth. | |
| From: John Searle (Rationality in Action [2001], Ch.4.III) |
| 3837 | We can't understand something as a lie if beliefs aren't commitment to truth [Searle] |
| Full Idea: If I lie and say "It is raining", my utterance is intelligible to me as a lie precisely because I understand that the utterance commits me to the truth of a proposition I do not believe to be true. | |
| From: John Searle (Rationality in Action [2001], Ch.6.II) |
| 3816 | Our beliefs are about things, not propositions (which are the content of the belief) [Searle] |
| Full Idea: The terminology of "propositional attitudes" is confused, because it suggests that a belief is an attitude towards a propositions, …but the proposition is the content, not the object, of my belief. | |
| From: John Searle (Rationality in Action [2001], Ch.2) |
| 3828 | Thinking must involve a self, not just an "it" [Searle] |
| Full Idea: We should not say "It thinks" in preference to "I think". If thinking is an active, voluntary process, there must be a self who thinks. | |
| From: John Searle (Rationality in Action [2001], Ch.3.IX) |
| 3831 | Reasons can either be facts in the world, or intentional states [Searle] |
| Full Idea: Both reasons and the things they are reasons for can be either facts in the world or intentional states such as beliefs, desires, and intentions. | |
| From: John Searle (Rationality in Action [2001], Ch.4.I) | |
| A reaction: One might point out that beliefs, desires and intentions are facts in the world too. Implicit dualism. One can ask, what turns a fact into a reason? |
| 3830 | In the past people had a reason not to smoke, but didn't realise it [Searle] |
| Full Idea: For a long time people had a reason not to smoke cigarettes, without knowing that they had such a reason. | |
| From: John Searle (Rationality in Action [2001], Ch.4) | |
| A reaction: What does 'had' a reason mean here? If I wish you dead, there is a reason why you should be dead, but you don't 'have' the reason, and never will have. There's probably a reason why I should never have been born. |
| 3832 | Causes (usually events) are not the same as reasons (which are never events) [Searle] |
| Full Idea: Causes are typically events, reasons are never events. You can give a reason by stating a cause, but it does not follow that the reason and the cause are the same thing. | |
| From: John Searle (Rationality in Action [2001], Ch.4.I) | |
| A reaction: This is against Davidson. I'm with Searle here; my having a reason to do something is not the cause of my doing it. I don't, unlike Searle, believe in free will, but doing something for a reason is not just the operation of the reason. |
| 3823 | Being held responsible for past actions makes no sense without personal identity [Searle] |
| Full Idea: I am held responsible now for things that I did in the distant past. But that only makes sense if there is some entity that is both the agent of the action in the past and me now. | |
| From: John Searle (Rationality in Action [2001], Ch.3.VII) | |
| A reaction: A possible response, of course, is that you are held responsible for your past deeds, but you shouldn't be. The idea that you are the same as when you committed the crime is a convenient fiction for people who desire revenge. Responsibility fades. |
| 3821 | Giving reasons for action requires reference to a self [Searle] |
| Full Idea: The requirement that I state reasons that I acted on requires a reference to the self. …Only for a self can something be a reason for an action. | |
| From: John Searle (Rationality in Action [2001], Ch.3.VII) | |
| A reaction: Why can't we just say that this reason, given this desire and this belief, led to this action, and never mention the self? Admittedly leaving out 'I' is an odd circumlocution, but I don't find this particular argument very convincing. |
| 3824 | A 'self' must be capable of conscious reasonings about action [Searle] |
| Full Idea: In order to be a self the entity that acts as an agent must also be capable of conscious reasoning about its actions. | |
| From: John Searle (Rationality in Action [2001], Ch.3.VIII) | |
| A reaction: I can't accept this all-or-nothing account. A chimpanzee is some sort of 'agent', and there are bad chimpanzees you wouldn't want in your colony. Why does Searle want to cut us off in some special compound where our actions are totally different? |
| 3834 | An intentional, acting, rational being must have a self [Searle] |
| Full Idea: Selfhood in my sense comes for free once you have a conscious intentional being capable of engaging in free actions on the basis of reasons. | |
| From: John Searle (Rationality in Action [2001], Ch.5.II) | |
| A reaction: The concept of an 'action' is probably the thing that most clearly needs a self, because it implies co-ordination and purpose, and there must be some item which benefits. Personally I think you can drop 'free actions' and still have a self. |
| 3825 | Action requires a self, even though perception doesn't [Searle] |
| Full Idea: It is a formal requirement on rational action that there must be a self who acts, in a way that it is not a formal requirement on perception that there be an agent or a self who perceives. | |
| From: John Searle (Rationality in Action [2001], Ch.3.IX) | |
| A reaction: I don't find this persuasive. I don't see how we can rule out a priori the possibility of a set of desires and reasons within an organism which generate an action, without any intervening 'self' to add something. Ockham's Razor. |
| 3829 | Selfs are conscious, enduring, reasonable, active, free, and responsible [Searle] |
| Full Idea: A self is conscious, persists through time, operates with reasons, carries out free actions, and is responsible. | |
| From: John Searle (Rationality in Action [2001], Ch.3.X) | |
| A reaction: Personally I would substitute 'makes decisions' for 'carries out free actions', but otherwise I agree, though he seems to miss a key aspect, which is that the self is in charge of the mind, and directs its focus and co-ordinates its inputs and outputs. |
| 3826 | A self must at least be capable of consciousness [Searle] |
| Full Idea: The first condition on the self is that it should be capable of consciousness. | |
| From: John Searle (Rationality in Action [2001], Ch.3.IX) | |
| A reaction: This strikes me as a stipulative definition. It raises the question of whether it is possible that a lizard (say) is not actually conscious, but has some sort of propriotreptic awareness, and a 'central controller' for its decision-making. |
| 3827 | The self is neither an experience nor a thing experienced [Searle] |
| Full Idea: The self is not an experience, nor is it an object that is experienced. | |
| From: John Searle (Rationality in Action [2001], Ch.3.IX) | |
| A reaction: A nice dichotomy, that draws attention to the unique position of the self. Thanks to Descartes for focusing our attention on it. Personally I would say that the self is an object, which cannot be experienced by itself, but can be inferred by others. |
| 3820 | The bundle must also have agency in order to act, and a self to act rationally [Searle] |
| Full Idea: Agency must be added to the bundle to account for how embodied bundles engage in free actions, and selfhood must be added to account for how agents can act rationally. | |
| From: John Searle (Rationality in Action [2001], Ch.3.VII) | |
| A reaction: I don't buy much of this, but I am inclined to say that a will must be added to the bundle to explain why it acts consistently and coherently. It is certainly ridiculous to rest with the picture of a person as a completely unstructured bundle. |
| 3817 | Free will is most obvious when we choose between several reasons for an action [Searle] |
| Full Idea: The most dramatic manifestation of the free will gap is that when one has several reasons for performing an action, one may act on only one of them; one may select which reason one acts on. | |
| From: John Searle (Rationality in Action [2001], Ch.3.II) |
| 3808 | Rational decision making presupposes free will [Searle] |
| Full Idea: In order to engage in rational decision making we have to presuppose free will. | |
| From: John Searle (Rationality in Action [2001], Ch.1.II) |
| 3818 | We freely decide whether to make a reason for action effective [Searle] |
| Full Idea: Where free rational action is concerned, all effective reasons are made effective by the agent. | |
| From: John Searle (Rationality in Action [2001], Ch.3.II) |
| 3814 | Preferences can result from deliberation, not just precede it [Searle] |
| Full Idea: A well-ordered set of preferences is typically the result of successful deliberation, and is not its precondition. | |
| From: John Searle (Rationality in Action [2001], Ch.1.II) |
| 3840 | We don't accept practical reasoning if the conclusion is unpalatable [Searle] |
| Full Idea: If I desire to get rid of my flu symptoms, and believe the only way to do it is death, I am committed to desiring my death. …there is no plausible logic of practical reason. | |
| From: John Searle (Rationality in Action [2001], Ch.8.II) |
| 3815 | The essence of humanity is desire-independent reasons for action [Searle] |
| Full Idea: The single greatest difference between humans and other animals as far as rationality is concerned is our ability to create, recognise and act on desire-independent reasons for action. | |
| From: John Searle (Rationality in Action [2001], Ch.1.II) |
| 3839 | Only an internal reason can actually motivate the agent to act [Searle] |
| Full Idea: Only an internal reason can actually motivate the agent to act. | |
| From: John Searle (Rationality in Action [2001], Ch.6 App) |
| 3835 | If it is true, you ought to believe it [Searle] |
| Full Idea: To say that something is true is already to say that you ought to believe it. | |
| From: John Searle (Rationality in Action [2001], Ch.5.II) | |
| A reaction: I'm sure what Einstein said is true, but I don't understand it. The truth is the thought of how things actually are, but why should I not prefer my private fantasies? I see the point, though. |
| 3836 | If this is a man, you ought to accept similar things as men [Searle] |
| Full Idea: From the fact that an object is truly described as "a man", it follows that you ought to accept relevantly similar objects as men. | |
| From: John Searle (Rationality in Action [2001], Ch.5.IV) | |
| A reaction: 'Similar' rather begs the question. Common speech distinguishes sharply between a man and a 'real man'. You only accept them as men if you see them as men, not as similar to something else. Interesting. |
| 3838 | Promises hold because I give myself a reason, not because it is an institution [Searle] |
| Full Idea: The obligation to keep a promise does not derive from the institution of promising, ..but from the fact that in promising I freely and voluntarily create a reason for myself. | |
| From: John Searle (Rationality in Action [2001], Ch.6.IV) |
| 3813 | 'Ought' implies that there is a reason to do something [Searle] |
| Full Idea: To say that someone 'ought' to do something is to imply that there is a reason for him to do it. | |
| From: John Searle (Rationality in Action [2001], Ch.1.II) |
| 17006 | Prime matter has no place in Aristotle's theories, and passages claiming it are misread [Gill,ML] |
| Full Idea: I argue that prime matter has no place in Aristotle's elemental theory. ..References to prime matter are found in Aristotle's work because his theory was thought to need the doctrine. If I am right, these passages will all admit of another interpretation. | |
| From: Mary Louise Gill (Aristotle on Substance [1989], App) | |
| A reaction: If correct, this strikes me as important for the history of ideas, because scholastics got themselves in a right tangle over prime matter. See Pasnau on it. It pushed the 17th century into corpuscularianism. |
| 16093 | Prime matter is actually nothing and potentially everything (or potentially an element) [Gill,ML] |
| Full Idea: Prime matter is supposed to be actually nothing and potentially everything or, at any rate, potentially the simplest bodies - earth, water, air and fire. | |
| From: Mary Louise Gill (Aristotle on Substance [1989], Ch.1) | |
| A reaction: The view that the four elements turn out to be prime matter is distinctive of Gill's approach. Prime matter sounds like quark soup in the early universe. |
