2. Reason / A. Nature of Reason / 1. On Reason
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)
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)
2. Reason / A. Nature of Reason / 8. Naturalising Reason
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)
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)
2. Reason / F. Fallacies / 1. Fallacy
It is a fallacy to explain the obscure with the even more obscure [Hale/Wright]
     Full Idea: The fallacy of 'ad obscurum per obscurius' is to explain the obscure by appeal to what is more obscure.
     From: B Hale / C Wright (The Metaontology of Abstraction [2009], §3)
     A reaction: Not strictly a fallacy, so much as an example of inadequate explanation, along with circularity and infinite regresses.
5. Theory of Logic / A. Overview of Logic / 1. Overview of Logic
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)
5. Theory of Logic / F. Referring in Logic / 1. Naming / d. Singular terms
Singular terms refer if they make certain atomic statements true [Hale/Wright]
     Full Idea: Anyone should agree that a justification for regarding a singular term as having objectual reference is provided just as soon as one has justification for regarding as true certain atomic statements in which it functions as a singular term.
     From: B Hale / C Wright (The Metaontology of Abstraction [2009], §9)
     A reaction: The meat of this idea is hidden in the word 'certain'. See Idea 10314 for Hale's explanation. Without that, the proposal strikes me as absurd.
5. Theory of Logic / I. Semantics of Logic / 1. Semantics of Logic
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)
6. Mathematics / C. Sources of Mathematics / 6. Logicism / c. Neo-logicism
Neo-Fregeanism might be better with truth-makers, rather than quantifier commitment [Hale/Wright]
     Full Idea: A third way has been offered to 'make sense' of neo-Fregeanism: we should reject Quine's well-known criterion of ontological commitment in favour of one based on 'truth-maker theory'.
     From: B Hale / C Wright (The Metaontology of Abstraction [2009], §4 n19)
     A reaction: [The cite Ross Cameron for this] They reject this proposal, on the grounds that truth-maker theory is not sufficient to fix the grounding truth-conditions of statements.
6. Mathematics / C. Sources of Mathematics / 6. Logicism / d. Logicism critique
Are neo-Fregeans 'maximalists' - that everything which can exist does exist? [Hale/Wright]
     Full Idea: It is claimed that neo-Fregeans are committed to 'maximalism' - that whatever can exist does.
     From: B Hale / C Wright (The Metaontology of Abstraction [2009], §4)
     A reaction: [The cite Eklund] They observe that maximalism denies contingent non-existence (of the £20 note I haven't got). There seems to be the related problem of 'hyperinflation', that if abstract objects are generated logically, the process is unstoppable.
7. Existence / C. Structure of Existence / 5. Supervenience / b. Types of supervenience
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.
7. Existence / D. Theories of Reality / 11. Ontological Commitment / a. Ontological commitment
The identity of Pegasus with Pegasus may be true, despite the non-existence [Hale/Wright]
     Full Idea: Identity is sometimes read so that 'Pegasus is Pegasus' expresses a truth, the non-existence of any winged horse notwithstanding.
     From: B Hale / C Wright (The Metaontology of Abstraction [2009], §5)
     A reaction: This would give you ontological commitment to truth, without commitment to existence. It undercuts the use of identity statements as the basis of existence claims, which was Frege's strategy.
8. Modes of Existence / B. Properties / 3. Types of Properties
Maybe we have abundant properties for semantics, and sparse properties for ontology [Hale/Wright]
     Full Idea: There is a compatibilist view which says that it is for the abundant properties to play the role of 'bedeutungen' in semantic theory, and the sparse ones to address certain metaphysical concerns.
     From: B Hale / C Wright (The Metaontology of Abstraction [2009], §9)
     A reaction: Only a philosopher could live with the word 'property' having utterly different extensions in different areas of discourse. They similarly bifurcate words like 'object' and 'exist'. Call properties 'quasi-properties' and I might join in.
8. Modes of Existence / B. Properties / 10. Properties as Predicates
A successful predicate guarantees the existence of a property - the way of being it expresses [Hale/Wright]
     Full Idea: The good standing of a predicate is already trivially sufficient to ensure the existence of an associated property, a (perhaps complex) way of being which the predicate serves to express.
     From: B Hale / C Wright (The Metaontology of Abstraction [2009], §9)
     A reaction: 'Way of being' is interesting. Is 'being near Trafalgar Sq' a way of being? I take properties to be 'features', which seems to give a clearer way of demarcating them. They say they are talking about 'abundant' (rather than 'sparse') properties.
8. Modes of Existence / C. Powers and Dispositions / 1. Powers
Powers give explanations, without being necessary for some class membership [Chakravartty]
     Full Idea: Powers explain behaviours regardless of whether they are necessary for membership in a particular class of things.
     From: Anjan Chakravarrty (Inessential Aristotle: Powers without Essences [2012], 3)
     A reaction: This seems right, and is important for driving a wedge between powers and essences. If there are essences, they are not simply some bunch of powers.
9. Objects / D. Essence of Objects / 5. Essence as Kind
A kind essence is the necessary and sufficient properties for membership of a class [Chakravartty]
     Full Idea: The modern concept of a kind essence is a set of intrinsic properties that are individually necessary and jointly sufficient for the membership of something in a class of things, or 'kind'.
     From: Anjan Chakravarrty (Inessential Aristotle: Powers without Essences [2012], 2)
     A reaction: I am always struck by the problem that the kind itself is constructed from the individuals, so circularity always seems to loom.
9. Objects / D. Essence of Objects / 15. Against Essentialism
Cluster kinds are explained simply by sharing some properties, not by an 'essence' [Chakravartty]
     Full Idea: The fact that members of some cluster kinds are subjects of causal generalizations reflects the degree to which they share causally efficacious properties, not the fact that they may be composed of essence kinds per se.
     From: Anjan Chakravarrty (Inessential Aristotle: Powers without Essences [2012], 2)
     A reaction: I think this is right. I am a fan of individual essences, but not of kind essences. I take kinds, and kind explanations, to be straightforward inductive generalisations from individuals. Extreme stabilities give the illusion of a kind essence.
11. Knowledge Aims / A. Knowledge / 4. Belief / c. Aim of beliefs
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)
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)
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)
11. Knowledge Aims / B. Certain Knowledge / 4. The Cogito
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)
13. Knowledge Criteria / A. Justification Problems / 1. Justification / a. Justification issues
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?
13. Knowledge Criteria / C. External Justification / 1. External Justification
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.
13. Knowledge Criteria / C. External Justification / 2. Causal Justification
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.
14. Science / D. Explanation / 2. Types of Explanation / g. Causal explanations
Explanation of causal phenomena concerns essential kinds - but also lack of them [Chakravartty]
     Full Idea: Scientific practices such as prediction and explanation regarding causal phenomena are concerned not merely with kinds having essences, but also with kinds lacking them.
     From: Anjan Chakravarrty (Inessential Aristotle: Powers without Essences [2012], 1)
     A reaction: Not quite clear what he has in mind, but explanation should certainly involve a coherent picture, and not just the citation of some underlying causal mechanism.
16. Persons / A. Concept of a Person / 2. Persons as Responsible
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.
16. Persons / A. Concept of a Person / 3. Persons as Reasoners
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.
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?
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.
16. Persons / A. Concept of a Person / 4. Persons as Agents
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.
16. Persons / B. Nature of the Self / 1. Self and Consciousness
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.
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.
16. Persons / B. Nature of the Self / 4. Presupposition of Self
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.
16. Persons / B. Nature of the Self / 5. Self as Associations
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.
16. Persons / F. Free Will / 4. For Free Will
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)
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)
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)
18. Thought / E. Abstraction / 7. Abstracta by Equivalence
Abstractionism needs existential commitment and uniform truth-conditions [Hale/Wright]
     Full Idea: Abstractionism needs a face-value, existentially committed reading of the terms occurring on the left-hand sides together with sameness of truth-conditions across the biconditional.
     From: B Hale / C Wright (The Metaontology of Abstraction [2009], §5)
     A reaction: They employ 'abstractionism' to mean their logical Fregean strategy for defining abstractions, not to mean the older psychological account. Thus the truth-conditions for being 'parallel' and for having the 'same direction' must be consistent.
Equivalence abstraction refers to objects otherwise beyond our grasp [Hale/Wright]
     Full Idea: Abstraction principles purport to introduce fundamental means of reference to a range of objects, to which there is accordingly no presumption that we have any prior or independent means of reference.
     From: B Hale / C Wright (The Metaontology of Abstraction [2009], §8)
     A reaction: There's the rub! They make it sound like a virtue, that we open up yet another heaven of abstract toys to play with. As fictions, they are indeed exciting new fun. As platonic discoveries they strike me as Cloud-Cuckoo Land.
19. Language / B. Reference / 4. Descriptive Reference / a. Sense and reference
Reference needs truth as well as sense [Hale/Wright]
     Full Idea: It takes, over and above the possession of sense, the truth of relevant contexts to ensure reference.
     From: B Hale / C Wright (The Metaontology of Abstraction [2009], §9)
     A reaction: Reference purely through sense was discredited by Kripke. The present idea challenges Kripke's baptismal realist approach. How do you 'baptise' an abstract object? But isn't reference needed prior to the establishment of truth?
20. Action / C. Motives for Action / 1. Acting on Desires
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)
20. Action / C. Motives for Action / 3. Acting on Reason / a. Practical reason
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)
20. Action / C. Motives for Action / 3. Acting on Reason / b. Intellectualism
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)
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)
22. Metaethics / B. Value / 1. Nature of Value / b. Fact and value
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.
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.
23. Ethics / B. Contract Ethics / 3. Promise Keeping
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)
23. Ethics / D. Deontological Ethics / 2. Duty
'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)
26. Natural Theory / B. Natural Kinds / 4. Source of Kinds
Some kinds, such as electrons, have essences, but 'cluster kinds' do not [Chakravartty]
     Full Idea: Many of the kinds we theorize about and experiment on today simply do not have essences. We can distinguish 'essence kinds', such as electrons, and 'cluster kinds', such as biological species.
     From: Anjan Chakravarrty (Inessential Aristotle: Powers without Essences [2012], 2)
     A reaction: This is an important point for essentialists. He offers a strict criterion, in Idea 15145, for mind membership, but we might allow species to have essences by just relaxing the criteria a bit, and acknowledging some vagueness, especially over time.
26. Natural Theory / D. Laws of Nature / 1. Laws of Nature
Many causal laws do not refer to kinds, but only to properties [Chakravartty]
     Full Idea: Causal laws often do not make reference to kinds of objects at all, but rather summarize relations between quantitative, causally efficacious properties of objects.
     From: Anjan Chakravarrty (Inessential Aristotle: Powers without Essences [2012], 3)
     A reaction: This would only be a serious challenge if it was not possible to translate talk of properties into talk of kinds, and vice versa.
