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)
3. Truth / B. Truthmakers / 2. Truthmaker Relation
Moral realism doesn't seem to entail the existence of any things [Cameron]
     Full Idea: Moral realism isn't realism about things, and it seems strange to suggest that moral realism is existence entailing in the way that realism about unobservable is.
     From: Ross P. Cameron (Truthmakers, Realism and Ontology [2008], 'Realism')
     A reaction: Cameron is questioning whether a realist has to believe in truthmakers. It seems to me that his doubts are because he insists that truthmaking is committed to the existence of 'things'. I assume any moral realism must supervene on nature.
3. Truth / B. Truthmakers / 3. Truthmaker Maximalism
Surely if some propositions are grounded in existence, they all are? [Cameron]
     Full Idea: What possible reason could one have for thinking of some propositions that they need to be grounded in what there is that doesn't apply to all propositions?
     From: Ross P. Cameron (Truthmakers, Realism and Ontology [2008], 'Max and Nec')
     A reaction: Well, if truthmaking said that all truths are grounded, then some could be grounded in what there is, and others in how it is, or maybe even how it isn't (if you get a decent account of negative truths).
3. Truth / B. Truthmakers / 4. Truthmaker Necessitarianism
Orthodox Truthmaker applies to all propositions, and necessitates their truth [Cameron]
     Full Idea: Orthodox truthmaker theory (Armstrong's) entails Maximalism (that every true proposition has at least one truthmaker), and Necessitarianism (that the existence of a truthmaker necessitates the truth of its proposition).
     From: Ross P. Cameron (Truthmakers, Realism and Ontology [2008], 'Max and Nec')
     A reaction: I think I accept both of these. If you say only some truths have truthmakers, the other truths are then baffling. And how could a truthmaker fail in its job? But that doesn't necessitate the existence of the proposition.
God fixes all the truths of the world by fixing what exists [Cameron]
     Full Idea: The truthmaker thought is that explanation only bottoms out at existence facts; for God to give a complete plan of the world He needs only make an inventory of what is to exist.
     From: Ross P. Cameron (Truthmakers, Realism and Ontology [2008], 'Max and Nec')
     A reaction: He is defending Necessitarianism about truthmaking. I'm struggling with this. An inventory of the contents of my house doesn't begin to fix all the truths that arise from them. Why is Cameron so resistent to 'how' things are being part of the truthmaking?
3. Truth / B. Truthmakers / 5. What Makes Truths / a. What makes truths
What the proposition says may not be its truthmaker [Cameron]
     Full Idea: The explanation of the truth of the proposition [p] doesn't stop at it being the case that p, so it's false to claim that whenever a proposition is true it's true in virtue of the world being as the proposition says it is. The features often lie deeper.
     From: Ross P. Cameron (Truthmakers, Realism and Ontology [2008], 'Grounding')
     A reaction: [He is opposing Jennifer Hornsby 2005] Cameron offers 'the average family has 2.4 children' as a counterexample' (since no one actually has 2.4 children). That seems compelling. Second example: 'the rose is beautiful'.
Rather than what exists, some claim that the truthmakers are ways of existence, dispositions, modalities etc [Cameron]
     Full Idea: Rivals to the truthmaker claim that facts about what there is are the truthmakers, there are theories that add facts about how the things are, or add dispositional facts, or modal facts, or haecceitistic facts, or maybe moral facts.
     From: Ross P. Cameron (Truthmakers, Realism and Ontology [2008], 'Grounding')
     A reaction: [compressed] He seems to think his version has a monopoly on truthmaking, but I don't see why these other theories shouldn't count as truthmaking. The truthmaker for 'live grenades are dangerous' is not just the existence of grenades.
Truthmaking doesn't require realism, because we can be anti-realist about truthmakers [Cameron]
     Full Idea: It's definitely not sufficient to be a realist that one be a truthmaker theorist, since one can simply be anti-realist about the truthmakers.
     From: Ross P. Cameron (Truthmakers, Realism and Ontology [2008], 'Realism')
     A reaction: It is not quite clear how unreal truth makers could actually MAKE propositions true, rather than just being correlated with them.
3. Truth / B. Truthmakers / 6. Making Negative Truths
Without truthmakers, negative truths must be ungrounded [Cameron]
     Full Idea: If negative truths don't have truthmakers then make no mistake: they are ungrounded.
     From: Ross P. Cameron (Truthmakers, Realism and Ontology [2008], 'Max and Nec')
     A reaction: What would be the grounding for truths which expressed the necessary preconditions for all existence? Could 'nothing whatever exists' ever be a truth?
3. Truth / B. Truthmakers / 11. Truthmaking and Correspondence
I support the correspondence theory because I believe in truthmakers [Cameron]
     Full Idea: I tend to think that the fundamental reason we can have the correspondence theory of truth is that truthmaker theory is correct.
     From: Ross P. Cameron (Truthmakers, Realism and Ontology [2008], 'Max and Nec')
     A reaction: [This responds to Fumerton 2006, who gives the opposite view] Cameron gives himself the classic problem of spelling out the correspondence relation (perhaps as 'congruence'). I like truthmaking, but I'm unsure about correspondence.
Maybe truthmaking and correspondence stand together, and are interdefinable [Cameron]
     Full Idea: One view says truthmaker theory stands or falls with the correspondence theory of truth, because the truthmaker for p is just the portion of reality that p corresponds to: truthmaker and correspondence can be conversely defined.
     From: Ross P. Cameron (Truthmakers, Realism and Ontology [2008], 'Max and Nec')
     A reaction: The normal view, which I prefer, is that correspondence is a particular theory of truthmaking, invoking a precise 'correspondence' relation. Hence abolishing correspondence would not abolish truthmaking, if you had a rival account.
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 / 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 / A. Nature of Mathematics / 4. Using Numbers / c. Counting procedure
Parsons says counting is tagging as first, second, third..., and converting the last to a cardinal [Parsons,C, by Heck]
     Full Idea: In Parsons's demonstrative model of counting, '1' means the first, and counting says 'the first, the second, the third', where one is supposed to 'tag' each object exactly once, and report how many by converting the last ordinal into a cardinal.
     From: report of Charles Parsons (Frege's Theory of Numbers [1965]) by Richard G. Heck - Cardinality, Counting and Equinumerosity 3
     A reaction: This sounds good. Counting seems to rely on that fact that numbers can be both ordinals and cardinals. You don't 'convert' at the end, though, because all the way you mean 'this cardinality in this order'.
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 / 2. Realism
Realism says a discourse is true or false, and some of it is true [Cameron]
     Full Idea: Realism about a discourse is 1) to think that the sentences are, when construed literally, literally true or false, and 2) to think that some of the sentences of the discourse are non-vacuously true.
     From: Ross P. Cameron (Truthmakers, Realism and Ontology [2008], 'Realism')
     A reaction: [Cameron adds 'non-vacuously' to an idea of Sayre-McCord 199 p.5] This is realism based on what is 'true', without specifying 'commitments', so I like it. Cameron says it makes mathematical postulationists into realists. He likes 'mind-independent'.
Realism says truths rest on mind-independent reality; truthmaking theories are about which features [Cameron]
     Full Idea: All that is necessary for realism, I claim, is that truth is grounded in mind-independent features of fundamental reality. Truthmaker theory comes into play because it is a theory about what those features are (…so it isn't a commitment to realism).
     From: Ross P. Cameron (Truthmakers, Realism and Ontology [2008], 'Realism')
     A reaction: [He cites Michael Devitt for this approach] What is the word 'fundamental' doing here? Because the mind-dependent parts of reality are considered non-fundamental? The no-true-Scotsman-hates-whisky move? His truthmaking is committed to 'things'.
For realists it is analytic that truths are grounded in the world [Cameron]
     Full Idea: The analytic commitment of realism is that truths are grounded in the world.
     From: Ross P. Cameron (Truthmakers, Realism and Ontology [2008], 'Grounding')
     A reaction: Certain fifth-level truths might be a long way from the actual world, and deeply interfused with human concepts and theories. Negative truths must be fitted into this picture.
10. Modality / E. Possible worlds / 2. Nature of Possible Worlds / a. Nature of possible worlds
We should reject distinct but indiscernible worlds [Cameron]
     Full Idea: I think we should reject distinct but indiscernible worlds.
     From: Ross P. Cameron (Truthmakers, Realism and Ontology [2008], 'Max and Nec')
     A reaction: An interesting passing remark. Presumably there would be unknowable truths about such worlds, which wouldn't bother a full-blooded realist. Indiscernible to whom? Me? Humanity? A divine mind?
11. Knowledge Aims / A. Knowledge / 4. Belief / c. Aim of beliefs
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)
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)
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.
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)
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)
