1. Philosophy / E. Nature of Metaphysics / 4. Metaphysics as Science
Ontology should give insight into or an explanation of the world revealed by science [Ellis]
     Full Idea: A good ontology should provide insight into, or offer some kind of explanation of, the salient general features of the world that has been revealed to us by science.
     From: Brian Ellis (Scientific Essentialism [2001], Intro)
     A reaction: I think I agree with this. The difficulty is that the most fundamental level revealed by science is a quantum one, so if you take a reductionist view then your ontology is both crazy, and resting on things which are not understood.
3. Truth / C. Correspondence Truth / 1. Correspondence Truth
Correspondence to the facts HAS to be the aim of enquiry [Searle]
     Full Idea: It does not matter whether "true" does mean corresponds to the facts, because "corresponds to the facts" does mean corresponds to the facts, and any discipline that aims to describe how the world is aims for this correspondence.
     From: John Searle (The Rediscovery of the Mind [1992], Ch.10.V)
4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / h. System S5
Real possibility and necessity has the logic of S5, which links equivalence classes of worlds of the same kind [Ellis]
     Full Idea: The logic of real possibilities and necessities is just S5. This is because the accessibility relation for real possibilities links possible worlds of the same natural kind, which is an equivalence class.
     From: Brian Ellis (Scientific Essentialism [2001], 7.06)
     A reaction: Most people, except Nathan Salmon, agree with this. With full accessibility, you seem to take epistemological problems out of the system, and just focus on reality.
5. Theory of Logic / I. Semantics of Logic / 5. Extensionalism
Humean conceptions of reality drive the adoption of extensional logic [Ellis]
     Full Idea: A Humean conception of reality lies behind, and motivates, the development of extensional logics with extensional semantics.
     From: Brian Ellis (Scientific Essentialism [2001], 8.04)
     A reaction: His proposal seems to be that it rests on the vision of a domain of separated objects. The alternative view seems to be that it is mathematics, with its absolute equality between 'objects', which drives extensionalism.
7. Existence / C. Structure of Existence / 2. Reduction
Reduction can be of things, properties, ideas or causes [Searle]
     Full Idea: I find at least five different senses of "reduction" in the literature - ontological (genes/DNA), property ontological (heat/mean molecular energy), theoretical (gas laws/statistics), logical/definitional (average plumber), and causal (solids/molecules).
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 5.II)
     A reaction: A useful pointer towards some much needed clearer thought about reduction. It is necessary to cross reference this list against reductions which are either ontological or epistemological or linguistic.
7. Existence / C. Structure of Existence / 5. Supervenience / c. Significance of supervenience
Solidity in a piston is integral to its structure, not supervenient [Maslin on Searle]
     Full Idea: Searle's defence of causally efficacious supervenient mind won't work, because, unlike the mind, the solidity of a piston is not a distinct and separate phenomenon from its microstructure.
     From: comment on John Searle (The Rediscovery of the Mind [1992], Ch. 5.V) by Keith T. Maslin - Introduction to the Philosophy of Mind 7.6
     A reaction: Searle struggles to find analogies for his position - and that, in my view, is highly significant in the philosophy of mind. If there is nothing else like your proposed theory, it is probably just human vainglory.
Is supervenience just causality? [Searle, by Maslin]
     Full Idea: For Searle the supervenience relation is just causality.
     From: report of John Searle (The Rediscovery of the Mind [1992], Ch. 5.V) by Keith T. Maslin - Introduction to the Philosophy of Mind 7.6
     A reaction: 'Supervenience' seems, in that case, to be an irrelevant word, which was only used when the mind-body connection was a bit loose and mysterious. Mind is identical to brain, or a property of the brain. I like 'process of the brain'.
7. Existence / D. Theories of Reality / 6. Physicalism
Reality is entirely particles in force fields [Searle]
     Full Idea: One can accept the obvious facts of physics, that the world consists entirely of physical particles in fields of force.
     From: John Searle (The Rediscovery of the Mind [1992], Intro)
     A reaction: I agree with this proposal, with the cautious proviso that physics may discover further basic aspects to reality. The only obstacles to this view are possible divine and mental substances, neither of which is supported by adequate evidence.
8. Modes of Existence / B. Properties / 1. Nature of Properties
The extension of a property is a contingent fact, so cannot be the essence of the property [Ellis]
     Full Idea: The extension of a property in any given world is just a contingent fact about that world; its extension is not the essence of the property.
     From: Brian Ellis (Scientific Essentialism [2001], 2.07)
     A reaction: The Quinean idea, common among logicians, that a predicate is just a set defined for some model, may be useful in the logic, but is preposterous as an account of what a property actually is in nature, even if the set covers possible worlds.
8. Modes of Existence / B. Properties / 5. Natural Properties
There is no property of 'fragility', as things are each fragile in a distinctive way [Ellis]
     Full Idea: There is no natural property of 'fragility'; glasses, parchments, ecosystems and spiders' webs are fragile in their own ways, but they have nothing intrinsic or structural in common.
     From: Brian Ellis (Scientific Essentialism [2001], 3.06)
     A reaction: This is important (and, I think, correct) because we are inclined to say that something is 'intrinsically' fragile, but that still isn't enough to identify a true property. Ellis wants universals to be involved, and even a nominalist must sort-of agree.
8. Modes of Existence / B. Properties / 6. Categorical Properties
Typical 'categorical' properties are spatio-temporal, such as shape [Ellis]
     Full Idea: The paradigmatically 'categorical' properties are spatio-temporal, depending on how things are distributed in space and time. Shape is the obvious example. ...Other examples are number, size and configuration.
     From: Brian Ellis (Scientific Essentialism [2001], 1.09)
     A reaction: I'm finding it very frustrating that this concept is much discussed in current philosophy of science (e.g. by Bird), but it is exceedingly hard to pin down any exact account of these 'categorical' properties, or even why they are so-called.
The property of 'being an electron' is not of anything, and only electrons could have it [Ellis]
     Full Idea: There is no property of being an electron. It could only be instantiated by electrons, so it does not seem genuine. And what is the thing that supposedly instantiates the property of being an electron?
     From: Brian Ellis (Scientific Essentialism [2001], 75,92), quoted by Stephen Mumford - Laws in Nature 7.3
     A reaction: I agree entirely. Bird launches an excellent attack on categorial properties.
8. Modes of Existence / B. Properties / 7. Emergent Properties
Some properties depend on components, others on their relations [Searle]
     Full Idea: Some system features cannot be figured out just from the composition of the elements of the system and environmental relations; they have to be explained in terms of causal relations among the elements.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 5.I)
     A reaction: One must explain at the molecular level why an apple skin is both red and smooth. In the brain one must explain the movement of glucose and the contents of thoughts by their causal relations (I say).
Fully 'emergent' properties contradict our whole theory of causation [Searle]
     Full Idea: The existence of any fully 'emergent' properties (that have a life of their own) violates even the weakest principle of the transitivity of causation.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 5.I)
     A reaction: When Searle talks like this, he sounds like a thoroughgoing reductive physicalist (but is he really?). Any philosopher of mind who uses the word 'emergence' must say EXACTLY what they mean by it.
8. Modes of Existence / B. Properties / 10. Properties as Predicates
'Being a methane molecule' is not a property - it is just a predicate [Ellis]
     Full Idea: In my view 'being a methane molecule' is not a property name, but a predicate that is constructed out of a natural kind name, and so pretends to name a property.
     From: Brian Ellis (Scientific Essentialism [2001], 2.03)
     A reaction: I can't tell you how strongly I agree with this. How long have you got? This is so incredibly right that... You get the idea. He observes that such properties cannot be instantiated 'in' anything.
8. Modes of Existence / C. Powers and Dispositions / 1. Powers
Causal powers must necessarily act the way they do [Ellis]
     Full Idea: There can be no question of a causal power's acting one way in one world and another way in a different world.
     From: Brian Ellis (Scientific Essentialism [2001], 1.12)
     A reaction: Perhaps the very core idea of scientific essentialism. It doesn't feel quite right that when you ask for the source of this necessity, you are only told that it is necessary for the very identity of a power. The truth is that it is a primitive of nature.
Causal powers are often directional (e.g. centripetal, centrifugal, circulatory) [Ellis]
     Full Idea: Causal powers are often directional. For example, they may be centripetal, centrifugal, or circulatory.
     From: Brian Ellis (Scientific Essentialism [2001], 3.11)
     A reaction: The examples all seem to raise a few questions, about whether the directionality arises from the context, rather than from the intrinsic power.
8. Modes of Existence / C. Powers and Dispositions / 3. Powers as Derived
Basic powers may not be explained by structure, if at the bottom level there is no structure [Ellis]
     Full Idea: It may be that the most fundamental things have no structure, and therefore no structure in virtue of which they have the powers they have.
     From: Brian Ellis (Scientific Essentialism [2001], Intro)
     A reaction: Maybe the world has inexplicable powers, so there is a God? It seems obvious that there will be no explanation of the 'lowest level' of reality, and also obvious (to me and Leibniz, anyway) that this lowest level has to be active.
Maybe dispositions can be explained by intrinsic properties or structures [Ellis]
     Full Idea: One view is that there must be an intrinsic property or structure in virtue of which a given thing has the behavioural disposition in question.
     From: Brian Ellis (Scientific Essentialism [2001], 3.06)
     A reaction: [He cites Prior, Pargetter,Jackson 1982] A key question in the metaphysics of nature - whether dispositions should be taken as primitive, or whether we should try to explain them in other terms. I take powers and dispositions to be prior to properties.
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / a. Dispositions
The most fundamental properties of nature (mass, charge, spin ...) all seem to be dispositions [Ellis]
     Full Idea: The properties of the most fundamental things in nature, including mass, charge, spin, and the like, would all appear to be dispositional.
     From: Brian Ellis (Scientific Essentialism [2001], 3.05)
     A reaction: This goes with the Leibnizian claim that the most fundamental features of nature must be active in character.
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / b. Dispositions and powers
A causal power is a disposition to produce forces [Ellis]
     Full Idea: A causal power is a disposition of something to produce forces of a certain kind.
     From: Brian Ellis (Scientific Essentialism [2001], 3.09)
     A reaction: Hence when Leibniz was putting all his emphasis on the origin of the forces in nature, he was referring to exactly what we mean by 'powers'. From Ellis's formulation, I take powers to be more basic than dispositions. Does he realise this?
Powers are dispositions of the essences of kinds that involve them in causation [Ellis]
     Full Idea: The causal powers of an object are the dispositional properties of that object that are the real essences of the natural kinds of processes that involve that object in the role of cause.
     From: Brian Ellis (Scientific Essentialism [2001], 3.11)
     A reaction: This is Ellis's formal definition at the end of his discussion of causal powers. He only seems to allow powers to the kind rather than to the individual. How do we account for the causal powers of unique genius? I say the powers are the essences.
8. Modes of Existence / D. Universals / 1. Universals
There are 'substantive' (objects of some kind), 'dynamic' (events of some kind) and 'property' universals [Ellis]
     Full Idea: Three categories of universals: 'substantive' universals have instances that are members of natural kinds of objects or substances; 'dynamic' universals are kinds of events or processes; 'property' universals are tropes of real properties or relations.
     From: Brian Ellis (Scientific Essentialism [2001], 1.01)
     A reaction: I would want to distinguish real properties from relations. It is important to remember that an object can traditionally instantiate a universal, and that they aren't just properties.
Universals are all types of natural kind [Ellis]
     Full Idea: The various kinds of universals are all natural kinds of one sort or another.
     From: Brian Ellis (Scientific Essentialism [2001], 1.01)
     A reaction: This doesn't sound right. What about the universals of mathematics, or universals which are a matter of social or linguistic convention? I think Ellis is trying to hijack the word 'universal' in response to Armstrong's more idealistic account.
9. Objects / D. Essence of Objects / 3. Individual Essences
Scientific essentialism doesn't really need Kripkean individual essences [Ellis]
     Full Idea: My current view is that individual essences (about which Kripke's essentialism has a lot to say) do not matter much from the point of view of a scientific essentialist.
     From: Brian Ellis (Scientific Essentialism [2001], Intro)
     A reaction: [Kripke parenthesis on p.54] Presumably this is because science is only committed to dealing in generalities, and so natural kinds are needed for such things. I'm inclined to regard individual essences as prior in the pure ontology of the thing.
9. Objects / D. Essence of Objects / 15. Against Essentialism
The old idea that identity depends on essence and behaviour is rejected by the empiricists [Ellis]
     Full Idea: The old Aristotelian idea that the identity of a thing might depend on its essential nature, which would dispose it to behave in certain ways, is firmly rejected by empiricists.
     From: Brian Ellis (Scientific Essentialism [2001], 1.10)
     A reaction: Ellis is accusing empiricists of having a falsely passive concept of objects. This dispute is best captured in the disagreement between Locke and Leibniz on the subject.
10. Modality / A. Necessity / 3. Types of Necessity
Necessities are distinguished by their grounds, not their different modalities [Ellis]
     Full Idea: Strictly speaking, the distinction between two brands of necessity is one of grounds, rather than modality.
     From: Brian Ellis (Scientific Essentialism [2001], 1.06)
     A reaction: This idea I associate with Kit Fine. I like it, because it allows 'necessity' to be a univocal concept, which seems right to me. The types of necessity arise from types of things which already occur in our ontology.
10. Modality / C. Sources of Modality / 6. Necessity from Essence
Individual essences necessitate that individual; natural kind essences necessitate kind membership [Ellis]
     Full Idea: There are necessities grounded in the individual real essences of things, and necessities grounded in the natural kind essences of things. In the first case, without the property it isn't that individual, and in the second it isn't a member of that kind.
     From: Brian Ellis (Scientific Essentialism [2001], Intro)
     A reaction: This is the distinction we must hang onto to avoid a huge amount of confusion in this territory. I just say that ceasing to be that individual will presumably entail ceasing to be that kind, but not necessarily vice versa, so individual essences rule.
11. Knowledge Aims / A. Knowledge / 4. Belief / e. Belief holism
Beliefs only make sense as part of a network of other beliefs [Searle]
     Full Idea: To have one belief or desire, I have to have a whole network of other beliefs and desires.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 8.I)
Beliefs are part of a network, and also exist against a background [Searle]
     Full Idea: We need to postulate a network of beliefs, and also a background of capacities that are not themselves part of the network.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 8.I)
12. Knowledge Sources / B. Perception / 5. Interpretation
Perception is a function of expectation [Searle]
     Full Idea: Psychologists have a lot of evidence to show that perception is a function of expectation.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 6.I.7)
12. Knowledge Sources / E. Direct Knowledge / 4. Memory
Memory is mainly a guide for current performance [Searle]
     Full Idea: We should think of memory as a mechanism for generating current performance, including conscious thoughts and actions, on the basis of past experience.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 8.III)
     A reaction: This seems to be falling into the fallacy of causal and functional theories, which Searle normally dislikes. If memory serves to aid current performance, that doesn't say what memory IS, any more than a foot is defined by walking.
14. Science / C. Induction / 3. Limits of Induction
If events are unconnected, then induction cannot be solved [Ellis]
     Full Idea: If one believes, as Hume did, that all events are loose and separate, then the problem of induction is probably insoluble.
     From: Brian Ellis (Scientific Essentialism [2001], 8.09)
     A reaction: This points to the essentialist solution of induction - that we can genuinely derive inductive truths if we can inductively identify the essences which give rise to the necessities of further cases. I take that to be a correct account.
14. Science / D. Explanation / 2. Types of Explanation / c. Explanations by coherence
Good explanations unify [Ellis]
     Full Idea: An acceptable explanation must have some unifying power.
     From: Brian Ellis (Scientific Essentialism [2001], 3.11)
     A reaction: There is a tension here, between the particular and the general. If I say 'why did the building collapse' and you say 'gravity', you have certainly got a unifying explanation, but we want something narrower.
14. Science / D. Explanation / 2. Types of Explanation / i. Explanations by mechanism
Explanations of particular events are not essentialist, as they don't reveal essential structures [Ellis]
     Full Idea: Explanations of particular events in history, geology, or evolution, are causal explanations, requiring belief in some causal mechanisms. But they are not essentialist explanations because they do not seek to lay bare the essential structure of anything.
     From: Brian Ellis (Scientific Essentialism [2001], 4.05)
     A reaction: The explanation might be two-stage, as when we explain an earthquake by a plate boundary rupture, which is in turn explained by a theory of plate techtonics. The relationship between mechanistic and essentialist explanation needs study.
14. Science / D. Explanation / 2. Types of Explanation / k. Explanations by essence
To give essentialist explanations there have to be natural kinds [Ellis]
     Full Idea: There can be no essentialist explanations constructed in any field where the subject matter is not naturally divided into kinds.
     From: Brian Ellis (Scientific Essentialism [2001], Intro)
     A reaction: A crux. I like individual essences, such as the character of a particular person. However, Ellis may be right, since while we may identify an individual essence as the source of a behaviour, we may not then be able to give any 'explanation'.
15. Nature of Minds / A. Nature of Mind / 4. Other Minds / c. Knowing other minds
We don't have a "theory" that other people have minds [Searle]
     Full Idea: Except when doing philosophy there is no "problem" of other minds, because we do not hold a "hypothesis" or "belief" or "supposition" that other people are conscious.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 3.IV)
     A reaction: Our commitment to other minds is so deep-ingrained that it is a candidate for one of Hume's 'natural beliefs', or even (a step further) for an innate idea. Babies have an innate recognition of faces, so why can't an expectation of a mind be hard-wired?
15. Nature of Minds / A. Nature of Mind / 4. Other Minds / d. Other minds by analogy
Other minds are not inferred by analogy, but are our best explanation [Searle]
     Full Idea: If we inferred other minds simply from behaviour, we would conclude that radios are conscious; it is rather the combination of behaviour with knowledge of the causal underpinnings of behaviour.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 1.V.4)
     A reaction: Personally I am inclined to think that Searle has said the last word on the fairly uninteresting problem of other minds. Dualism generates a deep privacy problem, and analogy is a flawed argument, but best explanation is exactly what we rely on.
15. Nature of Minds / A. Nature of Mind / 5. Unity of Mind
We experience unity at an instant and across time [Searle]
     Full Idea: We experience 'horizontal unity' in the organisation of conscious experiences through short stretches of time, and 'vertical unity' in simultaneous awareness of diverse features of our experience.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 6.I.2)
     A reaction: See Betjeman's poem "On the Ninth Green at St Enedoc". The brain is an information-unification machine, and 'I' am located at the crossroads where these unifications meet. Analysis of mind is good for us, but so is reunification afterwards.
15. Nature of Minds / B. Features of Minds / 1. Consciousness / b. Essence of consciousness
The mind experiences space, but it is not experienced as spatial [Searle]
     Full Idea: Although we experience objects both spatially and temporally, our consciousness itself is not experienced as spatial, though it is experienced as temporally extended.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 6)
     A reaction: This observation was made by Descartes. This seems to require that I experience objects spatially, AND experience my consciousness. Do I experience the time passing, as well as the river moving? Einstein says if it is in time, it must be in space.
15. Nature of Minds / B. Features of Minds / 1. Consciousness / d. Purpose of consciousness
Conscious creatures seem able to discriminate better [Searle]
     Full Idea: Apparently it is just a fact of biology that organisms that have consciousness have, in general, much greater powers of discrimination than those that do not.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 4.III)
     A reaction: This presupposes knowledge of which creatures are conscious. Clearly colour vision gives more information than monochrome vision. But presumably a computer could process more visual information than I could see. It doesn't have a fovea centralis.
15. Nature of Minds / B. Features of Minds / 2. Unconscious Mind
Unconscious thoughts are those capable of causing conscious ones [Searle]
     Full Idea: The ontology of the unconscious consists in objective features of the brain capable of causing subjective conscious thoughts.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 7.II.7)
     A reaction: As it stands, this definition would fit a brain tumour. I think Searle is wrong. There is no sharp line between conscious and non-conscious brain events. Research has surely made it clear that dim brain events directly intrude into my conscious states.
Consciousness results directly from brain processes, not from some intermediary like information [Searle]
     Full Idea: There are brain processes and consciousness, but nothing in between; no rule following, information processing, unconscious inferences, mental models, language of thought or universal grammar.
     From: John Searle (The Rediscovery of the Mind [1992], Ch.10.II)
     A reaction: The core of Searle's view. He likes to call consciousness a 'property' of brains. Edelman says consciousness IS a brain process. Essentially I agree with Searle. An unusual physical object can produce consciousness, but mere 'rules' etc. cannot.
15. Nature of Minds / B. Features of Minds / 4. Intentionality / a. Nature of intentionality
Either there is intrinsic intentionality, or everything has it [Searle]
     Full Idea: If you deny the distinction between intrinsic and derived ('as-if') intentionality, then it follows that everything in the universe has intentionality (for example, stones seem to want to fall).
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 3.IV)
     A reaction: Searle makes this claim because he always takes mental phenomena like intentionality or consciousness to be all-or-nothing - and he's wrong. He refuses to acknowledge non-conscious intentional states - and he's wrong again.
Water flowing downhill can be described as if it had intentionality [Searle]
     Full Idea: Water flowing downhill can be described AS IF it had intentionality: it tries to get to the bottom by seeking the line of least resistance through information processing and calculation…
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 7.II.1)
     A reaction: John Searle could be described as if he had intentionality, as his neurons chart their way through the information and desires that flood them. I am wary of his all-or-nothing approach to intentionality.
Intentional phenomena only make sense within a background [Searle]
     Full Idea: Intentional phenomena such as meanings, understandings, interpretations, beliefs, desires, and experiences only function within a set of Background capacities that are not themselves intentional.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 8.I)
     A reaction: Why would the background not be intentional? Presumably the background is a set of beliefs about, or images of, how the world is taken to be.
15. Nature of Minds / B. Features of Minds / 4. Intentionality / b. Intentionality theories
Intentionality is defined in terms of representation [Searle]
     Full Idea: Intentionality is defined in terms of representation.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 8.III)
     A reaction: Sounds okay, but representation of a tree (say) can be understood in imagistic terms, whereas extremely abstract concepts are a bit baffling. Then we realise that we conceive trees in that way as well, not as images.
Consciousness is essential and basic to intentionality [Searle]
     Full Idea: I claim that only a being that could have conscious intentional states could have intentional states at all, and every unconscious intentional state is at least potentially conscious.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 6.I.5)
     A reaction: The alternative to this is that robots and lower animals might have non-conscious states which are about something, because they process useful information but are unaware of it. If so, parts of the human mind might do the same, as in blindsight.
15. Nature of Minds / B. Features of Minds / 5. Qualia / b. Qualia and intentionality
Pain is not intentional, because it does not represent anything beyond itself [Searle]
     Full Idea: If I am conscious of a pain, the pain is not intentional, because it does not represent anything beyond itself.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 4.1)
     A reaction: Crane quotes this to challenge it. Pain may be about apparent damage to the body. Pains are certainly informative.
15. Nature of Minds / C. Capacities of Minds / 6. Idealisation
The point of models in theories is not to idealise, but to focus on what is essential [Ellis]
     Full Idea: Most model theories abstract from reality in order to focus on the essential nature of some kind of process or system of relations. ... The point of idealizing in this case is not to simplify, but to eliminate what is not essential.
     From: Brian Ellis (Scientific Essentialism [2001], 4.03)
     A reaction: I like this idea a lot. It is where scientific essentialism cashes out in actual scientific practice. Ellis's example is the idealised Carnot heat engine, which never can exist, but which captures what is essential about the process.
16. Persons / C. Self-Awareness / 1. Introspection
Neither introspection nor privileged access makes sense [Searle]
     Full Idea: We have the visual metaphor of introspection, and the spatial metaphor of privileged access, but neither one works because I am the thing being viewed, and I am the space being entered.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 4.II)
     A reaction: This is quite a good warning against reliance on analogies when dealing with the unique problem of self-knowledge, though the phrase 'hall-of-mirrors' draws assent from most people concerning that topic.
Introspection is just thinking about mental states, not a special sort of vision [Searle]
     Full Idea: If by "introspection" we mean simply thinking about our own mental states, then there is no objection to introspection, but if we mean a special capacity like vision of looking inwards, there is no such capacity.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 6.II.2)
     A reaction: This seems to beg the question of how we can be aware of our mental states in order to think about them. One might image that some animals have mental states, but are quite unaware that they have them, because they are totally focused on content.
16. Persons / C. Self-Awareness / 3. Limits of Introspection
I cannot observe my own subjectivity [Searle]
     Full Idea: I cannot observe my own subjectivity.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 4.II)
     A reaction: I'm not quite clear what Searle is complaining about. He knows very clearly that there is a subjective aspect to his life - so how does he know that fact? There must be something supporting this widely held belief.
17. Mind and Body / A. Mind-Body Dualism / 2. Interactionism
Mind and brain don't interact if they are the same [Searle]
     Full Idea: There is no "link" between consciousness and the brain, any more than there is a link between the liquidity of water and the H2O molecules.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 4.III)
     A reaction: We say of some properties that 'x is F', and of others that 'x has F', and of others that 'x is F because of y' (as in a knife having sharpness because it is thin and hard). Consciousness might fit the third case just as well as the first.
17. Mind and Body / A. Mind-Body Dualism / 7. Zombies
Without internal content, a zombie's full behaviour couldn't be explained [Searle]
     Full Idea: There could be no intentional zombie, because (unlike with a conscious agent) there simply is no fact of the matter as to exactly which aspectual shapes its alleged intentional states have. Is it seeking water or H2O?
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 7.III)
     A reaction: The obvious response to this is behaviourist talk of 'dispositions'. The dispositions of scientist when seeking water and when seeking H2O are different. Zombies behave identically to us, so their intentional states have whatever is needed to do the job.
17. Mind and Body / B. Behaviourism / 4. Behaviourism Critique
Mental states only relate to behaviour contingently, not necessarily [Searle]
     Full Idea: I believe that the relation of mental states to behaviour is purely contingent.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 1.V.5)
     A reaction: I don't think I agree, though it will depend on where you draw the line between mental states and behaviour. Since there have never been two identical states since the beginning of time, it is a little hard to test this one.
Wanting H2O only differs from wanting water in its mental component [Searle]
     Full Idea: If a person exhibits water-seeking behaviour, they also exhibit H2O-seeking behaviour, so there is no way the behaviour itself, without reference to a mental component, can constitute wanting water rather than H2O.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 7.II.4)
     A reaction: What about the behaviour of responding to the discovery that this stuff isn't actually H2O? Or the disposition to choose the real thing rather than ersatz water? An interesting comment, though.
17. Mind and Body / C. Functionalism / 1. Functionalism
Functionalists like the externalist causal theory of reference [Searle]
     Full Idea: Functionalism has been rejuvenated by being joined to externalist causal theories of reference.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 2.VIII)
     A reaction: This, however, seems to be roughly the reason why Putnam gave up his functionalist theory. See Ideas 2332 and 2071. However the causal network of mind can incorporate environmental features.
17. Mind and Body / C. Functionalism / 7. Chinese Room
A program for Chinese translation doesn't need to understand Chinese [Searle]
     Full Idea: A computer, me for example, could run the steps in the program for some mental capacity, such as understanding Chinese, without understanding a word of Chinese.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 9.II)
     A reaction: I don't think this is true. I could recite a bit of Chinese without comprehension, but giving flexible answers to complex questions isn't plausible just by gormlessly implementing a procedure.
17. Mind and Body / C. Functionalism / 8. Functionalism critique
Computation presupposes consciousness [Searle]
     Full Idea: Most of the works I have seen in the computational theory of the mind commit some variation on the homunculus fallacy.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 9.VI)
     A reaction: This will be because there is an unspoken user for the inner computer. But see Fodor's view (Idea 2506). The key idea here is Dennett's: that not all regresses are vicious. My mind controller isn't like all of me.
If we are computers, who is the user? [Searle]
     Full Idea: If the brain is a digital computer, we are still faced with the question 'Who is the user?'
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 9.VI)
     A reaction: A very nice question. Our whole current concept of a computer involves the unmentioned user. We don't have to go all mystical about persons, though. Robots aren't logically impossible.
17. Mind and Body / D. Property Dualism / 3. Property Dualism
Consciousness is a brain property as liquidity is a water property [Searle]
     Full Idea: Consciousness is a higher-level or emergent property of the brain, but only in the sense that solidity is an emergent property of water when it is ice, and liquidity when it melts.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 1.IV)
     A reaction: It is hard to know which side Searle is on. These examples are highly reductive, and make him a thoroughgoing reductive physicalist (with which I agree).
Property dualism is the reappearance of Cartesianism [Searle]
     Full Idea: Opponents of materialism tend to embrace "property dualism", thus accepting the Cartesian apparatus that I had thought long discredited.
     From: John Searle (The Rediscovery of the Mind [1992], Intro)
     A reaction: This seems to be precisely the current situation. Cartesian dualism is thoroughly marginalised (but still whimpering in the corner), and the real battle is between physicalism and property dualism. The latter is daft.
Property dualists tend to find the mind-body problem baffling [Searle]
     Full Idea: Property dualists (e.g. Nagel and McGinn) think that the mind-body problem is frightfully difficult, perhaps altogether insoluble.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 1.I)
     A reaction: Nagel's problem is that our concepts aren't up to it; McGinn's is that the very structure of our minds isn't up to it. My view is that the difficulty is the complexity we are up against, not the ontology.
Property dualism denies reductionism [Searle]
     Full Idea: What is property dualism but the view that there are irreducible mental properties?
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 5.III)
     A reaction: Being red and being square are separate, but they are both entailed by the material basis, and hence are reducible. Properties may not link directly, but they must link indirectly.
17. Mind and Body / D. Property Dualism / 5. Supervenience of mind
Mind and brain are supervenient in respect of cause and effect [Searle]
     Full Idea: Mind is supervenient on brain in the following respect: type-identical neurophysiological causes have type-identical mentalistic effects.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 5.V)
     A reaction: An interesting statement of what might be meant by 'supervenience'. Searle's version implies necessity in the link (but not identity). I take him to imply that a zombie is impossible.
If mind-brain supervenience isn't causal, this implies epiphenomenalism [Searle]
     Full Idea: There are constitutive and causal notions of supervenience. Kim claims that mental events have no causal role, and merely supervene on brain events which do (which implies epiphenomenalism). But it seems obvious that mind is caused by brain.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 5.V)
     A reaction: Personally I think the whole discussion is doomed to confusion because it is riddled with a priori dualism. There is no all-or-nothing boundary between 'mind' and 'brain'. Kim's views have changed.
Mental events can cause even though supervenient, like the solidity of a piston [Searle]
     Full Idea: That mental features supervene on neuronal features in no way diminishes their causal efficacy. The solidity of the piston is supervenient on its molecular structure, but this does not make solidity epiphenomenal.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 5.V)
     A reaction: Searle's examples never seem to quite fit what he is saying. Molecules and solidity are supervenient because they are identical (solidity is the presence of certain molecules). Solidity doesn't have causal powers that molecules lack.
Upwards mental causation makes 'supervenience' irrelevant [Searle]
     Full Idea: Once you recognise the existence of bottom-up, micro to macro forms of causation, the notion of supervenience no longer does any work in philosophy.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 5.V)
     A reaction: I'm not sure if the notion of supervenience ever did any work. Davidson only fished up the word because none of the normal relationships between things seemed to apply (and he was wrong about that).
17. Mind and Body / D. Property Dualism / 6. Mysterianism
Consciousness seems indefinable by conditions or categories [Searle]
     Full Idea: We can't define "consciousness" by necessary and sufficient conditions, or by the Aristotelian method of genus and differentia.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 4.I)
     A reaction: We may not be able to 'define' it, but we can 'characterise' it. The third approach to definition is a catalogue of essential properties, which might tail off rather vaguely.
17. Mind and Body / E. Mind as Physical / 2. Reduction of Mind
Can the homunculus fallacy be beaten by recursive decomposition? [Searle]
     Full Idea: The idea (of Dennett and others) is that recursive decomposition will eliminate the homunculi.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 9.VI)
     A reaction: Lycan is the best exponent of this view, which I like. My brain clearly has a substantial homunculus which I call my PA; it regularly reminds of what I have to do in an hour's time. I am sure it is composed of smaller brain components working as a team.
Searle argues that biology explains consciousness, but physics won't explain biology [Searle, by Kriegel/Williford]
     Full Idea: Searle appears to argue that phenomenal consciousness is explained in biological terms, but that biological properties are irreducible to purely (micro)physical ones.
     From: report of John Searle (The Rediscovery of the Mind [1992]) by U Kriegel / K Williford - Intro to 'Self-Representational Consciousness' n1
     A reaction: Searle is very hard to pin down, and this account suggests the reason very clearly - because he is proposing something which is bizarrely implausible. The reduction of biology-to-physics looks much more likely than consciousness-to-biology.
If mind is caused by brain, does this mean mind IS brain? [Searle]
     Full Idea: I hold a view of mind/brain relations that is a form of causal reduction (mental features are caused by biological processes), but does this imply ontological reduction? (…No!)
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 5.II.5)
     A reaction: What exactly is his claim? Presumably 'causal reduction' implies identity of (philosophical) substance. This seems to imply 'emergence' in a rather old-fashioned and dramatic way, though elsewhere Searle denies this.
17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / b. Multiple realisability
If mind is multiply realisable, it is possible that anything could realise it [Searle]
     Full Idea: The same principle that implies multiple realisability would seem to imply universal realisability. …Any object whatever could have syntactical ascriptions made to it.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 9.V)
     A reaction: This leads to rather weak reductio objections to functionalism. Logically there may be no restriction on how to implement a mind, but naturally there are very tight restrictions. Stick to neurons seems the best strategy.
18. Thought / A. Modes of Thought / 4. Folk Psychology
We don't postulate folk psychology, we experience it [Searle]
     Full Idea: We do not postulate beliefs and desires to account for anything; we simply experience conscious beliefs and desires.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 2 App)
     A reaction: Searle is too fond of reporting what we 'simply' know. Beliefs and desires are pushed forward by a cultural tradition. What I actually experience is a confusion, always laced with emotion.
18. Thought / B. Mechanics of Thought / 6. Artificial Thought / b. Turing Machines
Computation isn't a natural phenomenon, it is a way of seeing phenomena [Searle]
     Full Idea: Computational states are not discovered within the physics, they are assigned to the physics.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 9.V)
     A reaction: The key idea in Searle's later thinking, with which I have some sympathy. There always seems to be a sneaky dualism buried deep in Searle's physicalism. Computation is very high-level physics.
18. Thought / C. Content / 1. Content
Content is much more than just sentence meaning [Searle]
     Full Idea: Sentence meaning radically underdetermines the content of what is said.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 8.II)
     A reaction: We have body language, and we have tone, and we have context, and we have speaker's and listener's meanings. I take sentence meaning to be the basis which makes the rest possible.
18. Thought / C. Content / 6. Broad Content
There is no such thing as 'wide content' [Searle]
     Full Idea: I don't believe in the existence of 'wide content'.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 3.IV)
     A reaction: I sort of agree, but if I accept the rulings of experts (e.g. that water is really H2O), I am admitting that what I mean may not be in my head.
18. Thought / C. Content / 7. Narrow Content
We explain behaviour in terms of actual internal representations in the agent [Searle]
     Full Idea: In intentional explanations of behaviour patterns in the behaviour are explained by the fact that the agent has a representation of that very pattern in its intentional apparatus, which functions causally in the production of the behaviour.
     From: John Searle (The Rediscovery of the Mind [1992], Ch.10.IV)
     A reaction: Problem cases would be where someone's behaviour doesn't come out quite as planned (e.g. the sentence spoken failed to match the proposition intended), and panic behaviour.
19. Language / A. Nature of Meaning / 1. Meaning
Meaning is derived intentionality [Searle]
     Full Idea: Meaning is derived intentionality.
     From: John Searle (The Rediscovery of the Mind [1992], Intro)
     A reaction: That still leaves something very difficult to explain - how the intentionality of mental events can be 'transferred' to symbolic forms which can exist outside the mind.
19. Language / A. Nature of Meaning / 2. Meaning as Mental
Philosophy of language is a branch of philosophy of mind [Searle]
     Full Idea: On my view, the philosophy of language is a branch of the philosophy of mind.
     From: John Searle (The Rediscovery of the Mind [1992], Intro)
     A reaction: Inclined to agree with this. Intentionality and meaning are virtually the same thing. The role of language in thought has been grossly overrated in modern philosophy.
19. Language / C. Assigning Meanings / 1. Syntax
Universal grammar doesn't help us explain anything [Searle]
     Full Idea: No further predictive or explanatory power is added by saying that there is in addition a level of deep unconscious rules of universal grammar.
     From: John Searle (The Rediscovery of the Mind [1992], Ch.10.IV)
     A reaction: I would have thought that neuroscientists would be very interested in this prediction, if it were convincing enough. Nothing to stop us from trying to infer the nature of something which is beyond our reach.
19. Language / F. Communication / 6. Interpreting Language / b. Indeterminate translation
Shared Background makes translation possible, though variation makes it hard [Searle]
     Full Idea: Difference in local Backgrounds make translation from one language to another difficult; the commonality of deep Background makes it possible at all.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 8.V)
     A reaction: That is a very good observation about what is normally swept under the one umbrella of the 'principle of charity'. Quine exaggerated the local, and Davidson exaggerated the deep.
22. Metaethics / B. Value / 2. Values / b. Successful function
The function of a heart depends on what we want it to do [Searle]
     Full Idea: If the only thing that interested us about the heart was that it made a thumping noise, we would have a completely different conception of its "functioning", and correspondingly of heart disease.
     From: John Searle (The Rediscovery of the Mind [1992], Ch.10.III)
     A reaction: Ditto if we were only interested in ears as support for earrings, but that would seriously miss the point of ears. The intrinsic function is the reason for its existence.
26. Natural Theory / A. Speculations on Nature / 2. Natural Purpose / c. Purpose denied
Chemistry entirely explains plant behaviour [Searle]
     Full Idea: Variable secretions of auxin account for a plant's behaviour in following the sun, without any extra hypothesis of purpose, teleology, or intentionality.
     From: John Searle (The Rediscovery of the Mind [1992], Ch.10.II)
26. Natural Theory / A. Speculations on Nature / 5. Infinite in Nature
Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius]
     Full Idea: Archelaus was the first person to say that the universe is boundless.
     From: report of Archelaus (fragments/reports [c.450 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Ar.3
26. Natural Theory / B. Natural Kinds / 3. Knowing Kinds
There might be uninstantiated natural kinds, such as transuranic elements which have never occurred [Ellis]
     Full Idea: There are reasons to believe that there are natural kinds that might never be instantiated, such as a transuranic element, capable of existing for some fraction of a second, but which has never actually existed anywhere.
     From: Brian Ellis (Scientific Essentialism [2001], 2.05)
     A reaction: He cautiously claims that kinds are ontologically prior to their individual members. I would say that there is no natural kind of the type that he describes. He says you have at least some grounds for predicting what kinds are possible.
26. Natural Theory / B. Natural Kinds / 4. Source of Kinds
Natural kinds are distinguished by resting on essences [Ellis]
     Full Idea: Natural kinds are distinguished from other sorts of things by their associations with essential properties and real essences.
     From: Brian Ellis (Scientific Essentialism [2001], 1.02)
     A reaction: I don't think I agree with this. I rest my notion of natural kind on the elementary realising that to know all about this kind you only have to examine one sample of it, as in the Upanishads. The source of such a phenomenon is an open question.
26. Natural Theory / B. Natural Kinds / 7. Critique of Kinds
If there are borderline cases between natural kinds, that makes them superficial [Ellis]
     Full Idea: There cannot be any borderline cases between the real essences of different natural kinds because, if there were, the distinctions between the kinds would be superficial, like the blue/green distinction.
     From: Brian Ellis (Scientific Essentialism [2001], 1.05)
     A reaction: His particular target here is biological natural kinds, in which he doesn't believe, because they blur across time, in the evolutionary process. Personally I am inclined to relax the notion of a natural kind, otherwise they are too basic to explain.
26. Natural Theory / D. Laws of Nature / 1. Laws of Nature
Laws don't exist in the world; they are true of the world [Ellis]
     Full Idea: Laws are not things that exist in the world; they are things that are true of the world.
     From: Brian Ellis (Scientific Essentialism [2001], 3.09)
     A reaction: I'm happy with this formulation. The one to get rid of is the idea of laws which could precede creation of the universe, and survive its demise. That might be possible, but we have absolutely no grounds for the claim. Humeans ought to agree.
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / a. Scientific essentialism
A proton must have its causal role, because without it it wouldn't be a proton [Ellis]
     Full Idea: I assume it is metaphysically impossible for a proton to have a different causal role, ...which is plausible because a proton would appear to have no identity at all apart from its role in causal processes.
     From: Brian Ellis (Scientific Essentialism [2001], Intro)
     A reaction: This seems to be a key idea in scientific essentialism, which links essentialism of identity with essentialism in the laws of nature. Could a proton become not-quite-a-proton?
What is most distinctive of scientific essentialism is regarding processes as natural kinds [Ellis]
     Full Idea: What is most distinctive of the scientific version of essentialism is that scientific essentialists are realists about natural kinds of processes, as well as natural kinds of objects and substances.
     From: Brian Ellis (Scientific Essentialism [2001], 1.11)
     A reaction: I'm not sure whether other scientific essentialists would agree with this, but I am happy to go along with it. A process like melting or sublimation seems to be a standard widespread phenomenon which is always intrinsically the same, as kinds must be.
Scientific essentialism is more concerned with explanation than with identity (Locke, not Kripke) [Ellis]
     Full Idea: Scientific essentialism is less concerned with questions of identity, and more with questions of explanation, than is the essentialism of Aristotle or of Kripke. It is closest to the kind of essentialism described by Locke.
     From: Brian Ellis (Scientific Essentialism [2001], 1.12)
     A reaction: Locke is popularly held to be anti-essentialist, but that is only because of his epistemological problems. I think Ellis is here misreading Aristotle, and I would ally Aristotle, Locke (cautiously), Leibniz, Ellis and Fine against Kripkeans on this one.
The ontological fundamentals are dispositions, and also categorical (spatio-temporal and structural) properties [Ellis]
     Full Idea: We do not claim, as some do, that fundamental dispositional properties are the ontological basis of all properties. On the contrary, there are equally fundamental categorical properties - for example, spatio-temporal relations and structures.
     From: Brian Ellis (Scientific Essentialism [2001], 3.09)
     A reaction: The source of disagreement between Bird and Ellis. Bird denies the existence of 'categorical properties'. I think I am with Bird. Space and time are as much part of the given as the elements, and then categorical properties result from dispositions.
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / b. Scientific necessity
A primary aim of science is to show the limits of the possible [Ellis]
     Full Idea: Scientific essentialists hold that one of the primary aims of science is to define the limits of the possible.
     From: Brian Ellis (Scientific Essentialism [2001], 7.06)
     A reaction: I like this. It breaks down into the study of modal profiles, and it can work for abstracta as well as for the physical world. It even covers the study of character, and you could say that it is the subject matter of Jane Austen.
27. Natural Reality / G. Biology / 3. Evolution
Archelaus said life began in a primeval slime [Archelaus, by Schofield]
     Full Idea: Archelaus wrote that life on Earth began in a primeval slime.
     From: report of Archelaus (fragments/reports [c.450 BCE]) by Malcolm Schofield - Archelaus
     A reaction: This sounds like a fairly clearcut assertion of the production of life by evolution. Darwin's contribution was to propose the mechanism for achieving it. We should honour the name of Archelaus for this idea.
Mind involves fighting, fleeing, feeding and fornicating [Searle]
     Full Idea: Our conscious life involves the famous "four f's", fighting, fleeing, feeding and fornicating.
     From: John Searle (The Rediscovery of the Mind [1992], Ch.10.I)
28. God / A. Divine Nature / 4. Divine Contradictions
You can only know the limits of knowledge if you know the other side of the limit [Searle]
     Full Idea: To know the limits of knowledge, we would have to know both sides of the limit.
     From: John Searle (The Rediscovery of the Mind [1992], Ch. 1.V.6)
