1. Philosophy / E. Nature of Metaphysics / 3. Metaphysical Systems
Different abilities are needed for living in an incomplete and undogmatic system [Nietzsche]
     Full Idea: There is an entirely different strength and mobility to maintaining oneself in an incomplete system, with free, open vistas, than in a dogmatic world.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[025])
     A reaction: This is like Keats's 'negative capability' - the ability to live in a state of uncertainty. I'm a fan of attempts to create a philosophical system, but dogmatism would seem to be the death of such a project. How would you live with your system? Nice.
1. Philosophy / F. Analytic Philosophy / 4. Conceptual Analysis
Bad writers use shapeless floating splotches of concepts [Nietzsche]
     Full Idea: Bad writers have only shapeless floating splotches of concepts in their heads.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[083])
     A reaction: Under 'conceptual analyis' not because he analyses concepts, but because he recognises their foundation importance in philosophy. I get more irritated by unchallenged concepts than by drifting concepts. Writer must know and challenge their key concepts.
1. Philosophy / H. Continental Philosophy / 3. Hermeneutics
A text has many interpretations, but no 'correct' one [Nietzsche]
     Full Idea: The same text allows innumerable interpretations: there is no 'correct' interpretation.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 1[120])
     A reaction: It is hard to defend a 'correct' interpretation, but I think it is obvious to students of literature that some interpretations are very silly, such as reading things allegorically when there was no such intention.
3. Truth / A. Truth Problems / 3. Value of Truth
What is the search for truth if it isn't moral? [Nietzsche]
     Full Idea: What is searching for truth, truthfulness, honesty if not something moral?
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 35[05])
     A reaction: Feels right to me. It might be an effect of the virtue of respect. If you respect a person you tell them the truth (assuming they want the truth). Lying to someone is a sort of contempt.
Like all philosophers, I love truth [Nietzsche]
     Full Idea: I, too, love truth, like all philosophers.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 37[02])
     A reaction: Please pay attention to this remark! His perspectivalism is not a denial of truth. It is an epistemological phenomenon, not a metaphysical one. The perspectives are the nearest we can get to truth. Humanity therefore needs teamwork.
4. Formal Logic / F. Set Theory ST / 3. Types of Set / b. Empty (Null) Set
Realists about sets say there exists a null set in the real world, with no members [Chihara]
     Full Idea: In the Gödelian realistic view of set theory the statement that there is a null set as the assertion of the existence in the real world of a set that has no members.
     From: Charles Chihara (A Structural Account of Mathematics [2004], 11.6)
     A reaction: It seems to me obvious that such a claim is nonsense on stilts. 'In the beginning there was the null set'?
We only know relational facts about the empty set, but nothing intrinsic [Chihara]
     Full Idea: Everything we know about the empty set is relational; we know that nothing is the membership relation to it. But what do we know about its 'intrinsic properties'?
     From: Charles Chihara (A Structural Account of Mathematics [2004], 01.5)
     A reaction: Set theory seems to depend on the concept of the empty set. Modern theorists seem over-influenced by the Quine-Putnam view, that if science needs it, we must commit ourselves to its existence.
In simple type theory there is a hierarchy of null sets [Chihara]
     Full Idea: In simple type theory, there is a null set of type 1, a null set of type 2, a null set of type 3..... (Quine has expressed his distaste for this).
     From: Charles Chihara (A Structural Account of Mathematics [2004], 07.4)
     A reaction: It is bad enough trying to individuate the unique null set, without whole gangs of them drifting indistinguishably through the logical fog. All rational beings should share Quine's distaste, even if Quine is wrong.
The null set is a structural position which has no other position in membership relation [Chihara]
     Full Idea: In the structuralist view of sets, in structures of a certain sort the null set is taken to be a position (or point) that will be such that no other position (or point) will be in the membership relation to it.
     From: Charles Chihara (A Structural Account of Mathematics [2004], 11.6)
     A reaction: It would be hard to conceive of something having a place in a structure if nothing had a relation to it, so is the null set related to singeton sets but not there members. It will be hard to avoid Platonism here. Set theory needs the null set.
4. Formal Logic / F. Set Theory ST / 3. Types of Set / c. Unit (Singleton) Sets
What is special about Bill Clinton's unit set, in comparison with all the others? [Chihara]
     Full Idea: What is it about the intrinsic properties of just that one unit set in virtue of which Bill Clinton is related to just it and not to any other unit sets in the set-theoretical universe?
     From: Charles Chihara (A Structural Account of Mathematics [2004], 01.5)
     A reaction: If we all kept pet woodlice, we had better not hold a wood louse rally, or we might go home with the wrong one. My singleton seems seems remarkably like yours. Could we, perhaps, swap, just for a change?
4. Formal Logic / F. Set Theory ST / 5. Conceptions of Set / a. Sets as existing
The set theorist cannot tell us what 'membership' is [Chihara]
     Full Idea: The set theorist cannot tell us anything about the true relationship of membership.
     From: Charles Chihara (A Structural Account of Mathematics [2004], 01.5)
     A reaction: If three unrelated objects suddenly became members of a set, it is hard to see how the world would have changed, except in the minds of those thinking about it.
4. Formal Logic / F. Set Theory ST / 7. Natural Sets
ZFU refers to the physical world, when it talks of 'urelements' [Chihara]
     Full Idea: ZFU set theory talks about physical objects (the urelements), and hence is in some way about the physical world.
     From: Charles Chihara (A Structural Account of Mathematics [2004], 11.5)
     A reaction: This sounds a bit surprising, given that the whole theory would appear to be quite unaffected if God announced that idealism is true and there are no physical objects.
4. Formal Logic / F. Set Theory ST / 8. Critique of Set Theory
A pack of wolves doesn't cease when one member dies [Chihara]
     Full Idea: A pack of wolves is not thought to go out of existence just because some member of the pack is killed.
     From: Charles Chihara (A Structural Account of Mathematics [2004], 07.5)
     A reaction: The point is that the formal extensional notion of a set doesn't correspond to our common sense notion of a group or class. Even a highly scientific theory about wolves needs a loose notion of a wolf pack.
5. Theory of Logic / C. Ontology of Logic / 1. Ontology of Logic
Logic is a fiction, which invents the view that one thought causes another [Nietzsche]
     Full Idea: The model of a complete fiction is logic. Here a thinking is made up where a thought is posited as the cause of another thought.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[249])
     A reaction: He could almost be referring to Frege's Third Realm. Most hard core analytic philosophers seem to think that propositions have tight logical relationships which are nothing to do with the people who think them.
5. Theory of Logic / E. Structures of Logic / 6. Relations in Logic
The mathematics of relations is entirely covered by ordered pairs [Chihara]
     Full Idea: Everything one needs to do with relations in mathematics can be done by taking a relation to be a set of ordered pairs. (Ordered triples etc. can be defined as order pairs, so that <x,y,z> is <x,<y,z>>).
     From: Charles Chihara (A Structural Account of Mathematics [2004], 07.2)
     A reaction: How do we distinguish 'I own my cat' from 'I love my cat'? Or 'I quite like my cat' from 'I adore my cat'? Nevertheless, this is an interesting starting point for a discussion of relations.
5. Theory of Logic / F. Referring in Logic / 2. Descriptions / c. Theory of definite descriptions
The theory of descriptions supports internalism, since they are thinkable when the object is non-existent [Crane]
     Full Idea: The theory of descriptions gives a model of internalist intentionality, in that it describes cases where the thinkability of a belief does not depend on the existence of a specific object.
     From: Tim Crane (Elements of Mind [2001], 4.36)
     A reaction: So what do externalists say about the theory? Surely a reference to 'water' can't entail the existence of water?
5. Theory of Logic / K. Features of Logics / 2. Consistency
Sentences are consistent if they can all be true; for Frege it is that no contradiction can be deduced [Chihara]
     Full Idea: In first-order logic a set of sentences is 'consistent' iff there is an interpretation (or structure) in which the set of sentences is true. ..For Frege, though, a set of sentences is consistent if it is not possible to deduce a contradiction from it.
     From: Charles Chihara (A Structural Account of Mathematics [2004], 02.1)
     A reaction: The first approach seems positive, the second negative. Frege seems to have a higher standard, which is appealing, but the first one seems intuitively right. There is a possible world where this could work.
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / a. Numbers
Numbers enable us to manage the world - to the limits of counting [Nietzsche]
     Full Idea: Numbers are our major means of making the world manageable. We comprehend as far as we can count, i.e. as far as a constancy can be perceived.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[058])
     A reaction: I don't agree with 'major', but it is a nice thought. The intermediate concept is a 'unit', which means identifying something as a 'thing', which is how we seem to grasp the world. So to what extent do we comprehend the infinite. Enter Cantor…
6. Mathematics / B. Foundations for Mathematics / 3. Axioms for Geometry
Analytic geometry gave space a mathematical structure, which could then have axioms [Chihara]
     Full Idea: With the invention of analytic geometry (by Fermat and then Descartes) physical space could be represented as having a mathematical structure, which could eventually lead to its axiomatization (by Hilbert).
     From: Charles Chihara (A Structural Account of Mathematics [2004], 02.3)
     A reaction: The idea that space might have axioms seems to be pythagoreanism run riot. I wonder if there is some flaw at the heart of Einstein's General Theory because of this?
6. Mathematics / B. Foundations for Mathematics / 7. Mathematical Structuralism / c. Nominalist structuralism
We can replace existence of sets with possibility of constructing token sentences [Chihara, by MacBride]
     Full Idea: Chihara's 'constructability theory' is nominalist - mathematics is reducible to a simple theory of types. Instead of talk of sets {x:x is F}, we talk of open sentences Fx defining them. Existence claims become constructability of sentence tokens.
     From: report of Charles Chihara (A Structural Account of Mathematics [2004]) by Fraser MacBride - Review of Chihara's 'Structural Acc of Maths' p.81
     A reaction: This seems to be approaching the problem in a Fregean way, by giving an account of the semantics. Chihara is trying to evade the Quinean idea that assertion is ontological commitment. But has Chihara retreated too far? How does he assert existence?
7. Existence / B. Change in Existence / 4. Events / c. Reduction of events
Events are just interpretations of groups of appearances [Nietzsche]
     Full Idea: There is no event in itself. What happens is a group of appearances selected and summarised by an interpreting being.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 1[115])
     A reaction: Since innumerable events are nested within one another, such as the events at a carnival, this is obviously true. A primitive 'Kim event' (an object changes a property) might have objective existence. Carnivals happen, though.
7. Existence / C. Structure of Existence / 5. Supervenience / a. Nature of supervenience
Aesthetic properties of thing supervene on their physical properties [Crane]
     Full Idea: It is sometimes said that the aesthetic properties of a thing supervene on its physical properties.
     From: Tim Crane (Elements of Mind [2001], 2.16)
     A reaction: A confusing example, as aesthetic properties only exist if there is an observer. Is 'supervenience' just an empty locution which tries to avoid reduction?
7. Existence / C. Structure of Existence / 5. Supervenience / c. Significance of supervenience
Constitution (as in a statue constituted by its marble) is supervenience without identity [Crane]
     Full Idea: A statue is constituted by the marble that makes it up. It is plausible to say that constitution is not the same as identity - since identity is symmetrical and identity is not - but nonetheless constitution is a supervenience relation.
     From: Tim Crane (Elements of Mind [2001], 2.16)
     A reaction: So what makes it a statue, as opposed to a piece of marble? It may well be an abstraction which only exists relative to observers.
7. Existence / D. Theories of Reality / 11. Ontological Commitment / e. Ontological commitment problems
If a successful theory confirms mathematics, presumably a failed theory disconfirms it? [Chihara]
     Full Idea: If mathematics shares whatever confirmation accrues to the theories using it, would it not be reasonable to suppose that mathematics shares whatever disconfirmation accrues to the theories using it?
     From: Charles Chihara (A Structural Account of Mathematics [2004], 05.8)
     A reaction: Presumably Quine would bite the bullet here, although maths is much closer to the centre of his web of belief, and so far less likely to require adjustment. In practice, though, mathematics is not challenged whenever an experiment fails.
No scientific explanation would collapse if mathematical objects were shown not to exist [Chihara]
     Full Idea: Evidently, no scientific explanations of specific phenomena would collapse as a result of any hypothetical discovery that no mathematical objects exist.
     From: Charles Chihara (A Structural Account of Mathematics [2004], 09.1)
     A reaction: It is inconceivable that anyone would challenge this claim. A good model seems to be drama; a play needs commitment from actors and audience, even when we know it is fiction. The point is that mathematics doesn't collapse either.
8. Modes of Existence / B. Properties / 7. Emergent Properties
The distinction between 'resultant' properties (weight) and 'emergent' properties is a bit vague [Crane]
     Full Idea: The distinction between 'resultant' properties like weight, and 'emergent' properties like colour, seems intuitive enough, but on examination it is very hard to make precise.
     From: Tim Crane (Elements of Mind [2001], 2.18)
     A reaction: It is no coincidence that the examples are of primary and secondary qualities. If 'the physical entails the mental' then all mental properties are resultant.
If mental properties are emergent they add a new type of causation, and physics is not complete [Crane]
     Full Idea: Whatever the causal process is, it remains true that if emergentism is true, the completeness of physics is false; there are some effects which would not have come about if mental things were absent from the world.
     From: Tim Crane (Elements of Mind [2001], 2.18)
     A reaction: Emergentism looks to me like an incoherent concept, unless it is another word for dualism.
8. Modes of Existence / C. Powers and Dispositions / 5. Powers and Properties
Properties are causes [Crane]
     Full Idea: Properties are causes.
     From: Tim Crane (Elements of Mind [2001], 2.17)
     A reaction: We can't detect properties if they lack causal powers. This may be a deep confusion. Properties are what make causal powers possible, but that isn't what properties are?
9. Objects / B. Unity of Objects / 2. Substance / a. Substance
Traditional substance is separate from properties and capable of independent existence [Crane]
     Full Idea: The traditional concept of substance says substances bear properties which are distinct from them, and substances are capable of independent existence.
     From: Tim Crane (Elements of Mind [2001], 2.9)
     A reaction: Put like that, it sounds ridiculous as a physical theory. It is hard to dislodge substance, though, from a priori human metaphysics.
11. Knowledge Aims / A. Knowledge / 4. Belief / a. Beliefs
Maybe beliefs don't need to be conscious, if you are not conscious of the beliefs guiding your actions [Crane]
     Full Idea: The beliefs that are currently guiding your actions do not need to be in your stream of consciousness, which suggests that beliefs do not need to be conscious at all.
     From: Tim Crane (Elements of Mind [2001], 4.31)
     A reaction: Too bold, I think. Presumably this would eliminate all the other propositional attitudes from consciousness. There would only be qualia left!
Maybe there are two kinds of belief - 'de re' beliefs and 'de dicto' beliefs [Crane]
     Full Idea: Some philosophers have claimed that there are two kinds of belief, 'de re' belief and 'de dicto' belief.
     From: Tim Crane (Elements of Mind [2001], 4.35)
     A reaction: Interesting, though it may only distinguish two objects of belief, not two types. Internalist and externalist views are implied.
11. Knowledge Aims / A. Knowledge / 6. Knowing How
Many cases of knowing how can be expressed in propositional terms (like how to get somewhere) [Crane]
     Full Idea: There are plenty of cases of knowing how to do something, where that knowledge can also be expressed - without remainder, as it were - in propositional terms (such as knowing how to get to the Albert Hall).
     From: Tim Crane (Elements of Mind [2001], 3.28)
     A reaction: Presumably all knowing how could be expressed propositionally by God.
11. Knowledge Aims / B. Certain Knowledge / 5. Cogito Critique
The 'I' does not think; it is a construction of thinking, like other useful abstractions [Nietzsche]
     Full Idea: I do not grant to the metaphysicians that the 'I' is what thinks: on the contrary I take the I itself as a construction thinking, of the same rank as 'material',' thing', 'substance', 'purpose', 'number': therefore only as a regulative fiction.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 35[35])
     A reaction: Ah. I have always defended the Self, the thing that is in charge when the mind is directed to something. I suddenly see that this is compatible with the Self not being the thinker! It is just the willer, and the controller of the searchlight. Self = will?
11. Knowledge Aims / C. Knowing Reality / 2. Phenomenalism
Appearance is the sole reality of things, to which all predicates refer [Nietzsche]
     Full Idea: Appearance as I understand it is the actual and single reality of things - that which first merits all existing predicates.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 40[53])
     A reaction: This is the view espoused by John Stuart Mill (a fact which would shock Nietzsche!). Elsewhere he laughs at the concept of the thing-in-itself as a fiction.
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / d. Secondary qualities
Phenol-thio-urea tastes bitter to three-quarters of people, but to the rest it is tasteless, so which is it? [Crane]
     Full Idea: Phenol-thio-urea tastes bitter to three-quarters of people, but to the rest it is tasteless. Is it really bitter, or really tasteless?
     From: Tim Crane (Elements of Mind [2001], 5.44)
     A reaction: A nice reinforcement of a classic Greek question. Good support for the primary/secondary distinction. Common sense, really.
12. Knowledge Sources / B. Perception / 4. Sense Data / a. Sense-data theory
The traditional supports for the sense datum theory were seeing double and specks before one's eyes [Crane]
     Full Idea: The traditional examples used to support the sense datum theory were seeing double and specks before one's eyes.
     From: Tim Crane (Elements of Mind [2001], 5.43)
     A reaction: Presumably, though, direct realists can move one eye, or having something wrong with a retina.
One can taste that the wine is sour, and one can also taste the sourness of the wine [Crane]
     Full Idea: One can taste that the wine is sour, and one can also taste the sourness of the wine.
     From: Tim Crane (Elements of Mind [2001], 5.42)
     A reaction: …so sense data are optional? We create sense data by objectifying them, but animals just taste the wine, and are direct realists. Tasting the sourness seems to be a case of abstraction.
12. Knowledge Sources / B. Perception / 4. Sense Data / d. Sense-data problems
If we smell something we are aware of the smell separately, but we don't perceive a 'look' when we see [Crane]
     Full Idea: Visual perception seems to differ from some of the other senses; when we become aware of burning toast, we become aware of the smell, ...but we don't see a garden by seeing a 'look' of the garden.
     From: Tim Crane (Elements of Mind [2001], 5.40)
     A reaction: Interesting. Do blind people transfer this more direct perception to a different sense (e.g. the one they rely on most)?
The problems of perception disappear if it is a relation to an intentional state, not to an object or sense datum [Crane]
     Full Idea: The solution to the problem of perception is to deny that it is related to real objects (things or sense-data); rather, perception is an intentional state (with a subject, mode and content), a relation to the intentional content.
     From: Tim Crane (Elements of Mind [2001], 5.42)
     A reaction: Not clear. This definition makes it sound like a propositional attitude.
12. Knowledge Sources / B. Perception / 6. Inference in Perception
If perception is much richer than our powers of description, this suggests that it is non-conceptual [Crane]
     Full Idea: The richness in information of perceptual experience outruns our modes of description of it, which has led some philosophers to claim that the content of perceptual experience is non-conceptual.
     From: Tim Crane (Elements of Mind [2001], 5.45)
     A reaction: It certainly implies that it can't be entirely conceptual, but it still may be that in humans concepts are always involved. Not when I'm waking up in the morning, though.
12. Knowledge Sources / B. Perception / 8. Adverbial Theory
The adverbial theory of perceptions says it is the experiences which have properties, not the objects [Crane]
     Full Idea: The Adverbial Theory of perception holds that the predicates which other theories take as picking out the properties of objects are really adverbs of the perceptual verb; ..instead of strange objects, we just have properties of experiences.
     From: Tim Crane (Elements of Mind [2001], 5.42)
     A reaction: Promising. It fits secondary qualities all right, but what about primary? I 'see bluely', but can I 'see squarely'?
12. Knowledge Sources / E. Direct Knowledge / 4. Memory
Memory is essential, and is only possible by means of abbreviation signs [Nietzsche]
     Full Idea: Experience is only possible with the help of memory; memory is only possible by virtue of an abbreviation of an intellectual event as a sign.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[249])
     A reaction: My memory of a town is not formed as a sign, but as a bunch of miscellaneous fragments about it. I think mental files gives a better account of this than do 'signs'.
13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / c. Coherentism critique
Schematic minds think thoughts are truer if they slot into a scheme [Nietzsche]
     Full Idea: There are schematic minds, those who hold a thought-complex to be truer if it can be sketched into previously drafted schemata or categorical tables. There are countless self-deceptions in this area: nearly all the great 'systems' belong here.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 40[09])
     A reaction: Why 'nearly all'? Aristotle might be a candidate for such a person. Leibniz, perhaps. Nietzsche identified with Becoming and Heraclitus, as opposed to Being and Parmenides.
13. Knowledge Criteria / C. External Justification / 1. External Justification
Is knowledge just a state of mind, or does it also involve the existence of external things? [Crane]
     Full Idea: It is controversial whether knowledge is a state of mind, or a composite state involving a thought about something, plus its existence.
     From: Tim Crane (Elements of Mind [2001], 1.5)
     A reaction: Pinpoints the internalism/externalism problem. Knowledge is a special type of belief (but maybe belief with external links!). Tricky. I vote for internalism.
13. Knowledge Criteria / E. Relativism / 1. Relativism
Each of our personal drives has its own perspective [Nietzsche]
     Full Idea: From the standpoint of each of our fundamental drives there is a different perspectival assessment of all events and experiences.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 1[058])
     A reaction: Revealing. Perspectives are not just each individual person's viewpoint, but something more fine-grained than that. Our understanding and response are ambiguous, because we ourselves are intrinsically ambiguous. Super-relativism!
15. Nature of Minds / A. Nature of Mind / 1. Mind / b. Purpose of mind
The mind is a simplifying apparatus [Nietzsche]
     Full Idea: The intellect and the senses are above all a simplifying apparatus.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[046])
     A reaction: Very plausible, and not an idea I have met elsewhere. There's a PhD here for someone. It fits with my view as universals in language (which is most of language), which capture diverse things by ironing out their differences.
15. Nature of Minds / B. Features of Minds / 1. Consciousness / e. Cause of consciousness
The core of the consciousness problem is the case of Mary, zombies, and the Hard Question [Crane]
     Full Idea: The three arguments that have been used to articulate the problem of consciousness are the knowledge argument ('Mary'), the possibility of 'zombies' (creatures like us but lacking phenomenal consciousness), and the explanatory gap (the Hard Question).
     From: Tim Crane (Elements of Mind [2001], 3.26)
     A reaction: All of these push towards the implausible claim that there could never be a physical explanation of why we experience things. Zombies are impossible, in my opinion.
15. Nature of Minds / B. Features of Minds / 1. Consciousness / f. Higher-order thought
Consciousness is our awareness of our own mental life [Nietzsche]
     Full Idea: We have a double brain: our capacity to will, to feel and to think of our willing, feeling, thinking ourselves is what we summarise with the word 'consciousness'.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[087])
     A reaction: Pretty much the modern HOT (higher order thought) theory of consciousness. Higher order thought distinguishes us from the other animals, but I think they too are probably conscious, so I don't agree. Why is level 2 conscious of level 1?
15. Nature of Minds / B. Features of Minds / 4. Intentionality / a. Nature of intentionality
Intentionalism does not require that all mental states be propositional attitudes [Crane]
     Full Idea: Intentionalism (the doctrine that all mental states are intentional) need not be the thesis that all mental states are propositional attitudes.
     From: Tim Crane (Elements of Mind [2001], 3.22)
     A reaction: This points to the requirement for an intentionalist to prove that so-called 'qualia' states are essentially intentional, which is not implausible.
Object-directed attitudes like love are just as significant as propositional attitudes [Crane]
     Full Idea: Love, hate, and the other object-directed attitudes have as much of a role in explaining behaviour as the propositional attitudes.
     From: Tim Crane (Elements of Mind [2001], 4.34)
     A reaction: A good clarification of the range of intentional states. Objects seem to be external, where propositions are clearly internal.
15. Nature of Minds / B. Features of Minds / 5. Qualia / a. Nature of qualia
If someone removes their glasses the content of experience remains, but the quality changes [Crane]
     Full Idea: There is a phenomenal difference between a short-sighted person wearing glasses and not; they do not judge that the world is different, but the properties of the experience (the qualia) have changed.
     From: Tim Crane (Elements of Mind [2001], 5.43)
     A reaction: Could be challenged. If a notice becomes unreadable, that is more than the qualia changing.
15. Nature of Minds / B. Features of Minds / 5. Qualia / b. Qualia and intentionality
Pains have a region of the body as their intentional content, not some pain object [Crane]
     Full Idea: The intentional object of a pain-state is a part or region of the body, not a pain-object.
     From: Tim Crane (Elements of Mind [2001], 3.24)
     A reaction: Plausible. Has anyone ever suffered from pain without some sense of what part of the body is actually in pain?
15. Nature of Minds / B. Features of Minds / 5. Qualia / c. Explaining qualia
Weak intentionalism says qualia are extra properties; strong intentionalism says they are intentional [Crane]
     Full Idea: Weak intentionalism says all mental states are intentional, but qualia are higher-order properties of these states. ..Strong intentionalists say the phenomenal character of a sensation consists purely in that state's intentionality.
     From: Tim Crane (Elements of Mind [2001], 3.25)
     A reaction: The weak version sounds better. Asking 'how could a thought have a quality of experience just by being about something?' is a restatement of the traditional problem, which won't go away. The Hard Question.
15. Nature of Minds / B. Features of Minds / 6. Inverted Qualia
With inverted qualia a person's experiences would change, but their beliefs remain the same [Crane]
     Full Idea: The right thing to say about inverted qualia is that the person's experiences are different from other people's, but their beliefs are the same.
     From: Tim Crane (Elements of Mind [2001], 5.44)
     A reaction: Right - which reinforces the idea that all beliefs are the result of judgement, and none come directly from perception.
15. Nature of Minds / C. Capacities of Minds / 1. Faculties
Minds have an excluding drive to scare things off, and a selecting one to filter facts [Nietzsche]
     Full Idea: In our conscious intellect there must be an excluding drive that scares things away, a selecting one, which only permits certain facts to present themselves.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[131])
     A reaction: I like this because he is endorsing the idea that philosophy needs faculties, which may not match the views of psychologists and neuroscientists. Quite nice to think of faculties as drives.
15. Nature of Minds / C. Capacities of Minds / 10. Conatus/Striving
The greatest drive of life is to discharge strength, rather than preservation [Nietzsche]
     Full Idea: Something that lives wants above all to discharge its strength: 'preservation' is only one of the consequences of this.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 2[063])
     A reaction: This seems to fit a dynamic man like Nietzsche, rather than someone who opts for a quiet and comfortable life.
16. Persons / F. Free Will / 6. Determinism / a. Determinism
That all events are necessary does not mean they are compelled [Nietzsche]
     Full Idea: The absolute necessity of all events contains nothing of a compulsion.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 1[114])
     A reaction: I like to look for necessity-makers behind necessities. So if the event is not necessary because of its cause, where does it come from? Is it that the whole sequence is a unified necessity?
17. Mind and Body / A. Mind-Body Dualism / 1. Dualism
Descartes did not think of minds as made of a substance, because they are not divisible [Crane]
     Full Idea: It would be wrong to represent Descartes' view as the idea that bodies are made of one kind of stuff and minds of another; he did not think minds are made of stuff at all, because then they would be divisible.
     From: Tim Crane (Elements of Mind [2001], 2.10)
     A reaction: I'm not convinced. It could be an indivisible substance. Without a mental substance, Descartes may have to say the mind is an abstraction, perhaps a pattern of Platonic forms.
17. Mind and Body / A. Mind-Body Dualism / 6. Epiphenomenalism
Functionalism defines mental states by their causal properties, which rules out epiphenomenalism [Crane]
     Full Idea: Functionalism holds that it is in the nature of certain mental states to have certain effects; therefore there can be no mental epiphenomena.
     From: Tim Crane (Elements of Mind [2001], 2.14)
     A reaction: I strongly resist the idea that a thing's identity is its function. Functionalism may not say that. Mind is an abstraction referring to a causal nexus of unknowable components.
17. Mind and Body / D. Property Dualism / 1. Reductionism critique
The problems of misrepresentation and error have dogged physicalist reductions of intentionality [Crane]
     Full Idea: The fundamental problems of misrepresentation and error have dogged physicalist reductions of intentionality.
     From: Tim Crane (Elements of Mind [2001], 3.26)
     A reaction: If footprints or tree-rings are the model for reductions of intentionality, there doesn't seem much scope in them for giving false information, except by some freak event.
17. Mind and Body / D. Property Dualism / 3. Property Dualism
Properties dualism says mental properties are distinct from physical, despite a single underlying substance [Crane]
     Full Idea: According to property dualism, mental properties are distinct from physical properties, even though they are properties of one substance.
     From: Tim Crane (Elements of Mind [2001], 2.10)
     A reaction: Two properties may be phenomenologically different (transparent and magnetic), but that doesn't put them in different ontological categories.
17. Mind and Body / D. Property Dualism / 4. Emergentism
Non-reductive physicalism seeks an explanation of supervenience, but emergentists accept it as basic [Crane]
     Full Idea: While the non-reductive physicalist believes that mental/physical supervenience must be explained, the emergentist is willing to accept it as a fact of nature.
     From: Tim Crane (Elements of Mind [2001], 2.18)
     A reaction: A good reason not to be an emergentist. No philosopher should abandon the principle of sufficient reason.
17. Mind and Body / D. Property Dualism / 5. Supervenience of mind
If mental supervenes on the physical, then every physical cause will be accompanied by a mental one [Crane]
     Full Idea: If the mental supervenes on the physical, then whenever a physical cause brings about some effect, a mental cause comes along for the ride.
     From: Tim Crane (Elements of Mind [2001], 2.17)
     A reaction: This is why supervenience seems to imply epiphenomenalism. The very concept of supervenience is dubious.
17. Mind and Body / E. Mind as Physical / 1. Physical Mind
Identity theory is either of particular events, or of properties, depending on your theory of causation [Crane]
     Full Idea: If causation concerns events, then we have an identity theory of mental and physical events (particulars) [Davidson]. If causation is by properties, then it is mental and physical properties which are identical [Lewis and Armstrong].
     From: Tim Crane (Elements of Mind [2001], 2.14)
     A reaction: Events are tokens, and properties are types. Tricky. Events are dynamic, but properties can be static.
Physicalism may be the source of the mind-body problem, rather than its solution [Crane]
     Full Idea: Physicalism may be the source of the mind-body problem, rather than its solution.
     From: Tim Crane (Elements of Mind [2001], 2.19)
     A reaction: Certainly if the physical is seen as just a pile of atoms, it is hard to see how they could ever think (see idea 1909).
17. Mind and Body / E. Mind as Physical / 5. Causal Argument
Overdetermination occurs if two events cause an effect, when each would have caused it alone [Crane]
     Full Idea: Causal overdetermination is when an effect has more than one cause, and each event would have caused the effect if the other one had not done so.
     From: Tim Crane (Elements of Mind [2001], 2.13)
     A reaction: Overdetermination is a symptom that an explanation is questionable, but it can occur. Two strong people can join to push over a light hatstand.
17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / a. Physicalism critique
The completeness of physics must be an essential component of any physicalist view of mind [Crane]
     Full Idea: I claim that the completeness of physics must be an essential component of any physicalist view of mind.
     From: Tim Crane (Elements of Mind [2001], 2.12)
     A reaction: He does not convince me of this. The mind may be within physics, but why should we say a priori that no exceptions to physical law will ever be discovered. Crane is setting up straw men.
17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / c. Knowledge argument
Experience teaches us propositions, because we can reason about our phenomenal experience [Crane]
     Full Idea: In experience we learn propositions, since someone can reason using the sentence 'Red looks like this' (e.g. 'If red looks like this, then either it looks like this to dogs or it doesn't').
     From: Tim Crane (Elements of Mind [2001], 3.28)
     A reaction: The fact that we can create propositions about experiences doesn't prove that experience is inherently propositional.
18. Thought / C. Content / 5. Twin Earth
The Twin Earth argument depends on reference being determined by content, which may be false. [Crane]
     Full Idea: The Twin Earth argument does not refute internalism, since it depends on the 'Content-Determines-Reference' principle, which internalists can reject.
     From: Tim Crane (Elements of Mind [2001], 4.37)
     A reaction: The idea is that content should be understood in a context (e.g. on a particular planet). Indexicals count against a totally narrow view of content (Twins thinking 'I am here').
18. Thought / C. Content / 6. Broad Content
Broad content entails the existence of the object of the thought [Crane]
     Full Idea: If a mental state is broad, then the existence of the mental state entails the existence of its object.
     From: Tim Crane (Elements of Mind [2001], 1.7)
     A reaction: Hence thinking of non-existent things like unicorns is problematic for externalists. However, externalists can think about numbers or Platonic ideals.
18. Thought / C. Content / 8. Intension
In intensional contexts, truth depends on how extensions are conceived. [Crane]
     Full Idea: Intensional contexts are those where truth or falsehood depends on the way the extensions are conceived.
     From: Tim Crane (Elements of Mind [2001], 1.4)
     A reaction: An important distinction for anyone defending an internalist view of concepts or of knowledge
18. Thought / D. Concepts / 1. Concepts / a. Nature of concepts
Concepts are rough groups of simultaneous sensations [Nietzsche]
     Full Idea: Concepts are more or less definite groups of sensations that arrive together.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[086])
     A reaction: I like this because I favour accounts of concepts which root them in experience, and largely growing unthinking out of communcal experience. Nietzsche is very empirical here. Hume would probably agree.
Concepts don’t match one thing, but many things a little bit [Nietzsche]
     Full Idea: A concept is an invention that doesn't correspond entirely to anything; but to many things a little bit.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[131])
     A reaction: This seems to cover some concepts quite well, but others not at all. What else does 'square' correspond to?
18. Thought / D. Concepts / 2. Origin of Concepts / a. Origin of concepts
Whatever their origin, concepts survive by being useful [Nietzsche]
     Full Idea: The most useful concepts have survived: however falsely they may have originated.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[063])
     A reaction: The germ of both pragmatism, and of meaning-as-use, here. The alternative views must be that the concepts are accurate or true, or that they are simply a matter of whim, maintained by authority.
18. Thought / E. Abstraction / 7. Abstracta by Equivalence
I prefer the open sentences of a Constructibility Theory, to Platonist ideas of 'equivalence classes' [Chihara]
     Full Idea: What I refer to as an 'equivalence class' (of line segments of a particular length) is an open sentence in my Constructibility Theory. I just use this terminology of the Platonist for didactic purposes.
     From: Charles Chihara (A Structural Account of Mathematics [2004], 09.10)
     A reaction: This is because 'equivalence classes' is committed to the existence of classes, which is Quinean Platonism. I am with Chihara in wanting a story that avoids such things. Kit Fine is investigating similar notions of rules of construction.
19. Language / B. Reference / 3. Direct Reference / b. Causal reference
Mathematical entities are causally inert, so the causal theory of reference won't work for them [Chihara]
     Full Idea: Causal theories of reference seem doomed to failure for the case of reference to mathematical entities, since such entities are evidently causally inert.
     From: Charles Chihara (A Structural Account of Mathematics [2004], 01.3)
     A reaction: Presumably you could baptise a fictional entity such as 'Polonius', and initiate a social causal chain, with a tradition of reference. You could baptise a baby in absentia.
19. Language / D. Propositions / 1. Propositions
Thought starts as ambiguity, in need of interpretation and narrowing [Nietzsche]
     Full Idea: A thought in the shape in which it comes is an ambiguous sign that needs interpretation, more precisely, needs an arbitrary narrowing-down and limitation, until it finally becomes unambiguous.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 38[01])
     A reaction: This is exactly my view of propositions, as mental events. Introspect your thinking process. Track the progress from the first glimmer of a thought to its formulation in a finished sentence. Language, unlike propositions, can be ambiguous.
21. Aesthetics / A. Aesthetic Experience / 1. Aesthetics
Aesthetics can be more basic than morality, in our pleasure in certain patterns of experience [Nietzsche]
     Full Idea: Some of the aesthetic valuations are more fundamental than the moral ones e.g. the pleasure in what is ordered, surveyable, limited, in repetition. The logical, arithmetical and geometrical good feelings form the ground floor of aesthetic valuations.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 35[02])
     A reaction: Nietzsche's originality is so striking because his novel suggestions are always plausible. Lots of modern philosophers (especially, I fear, in the continental tradition) throw out startling ideas which then fail on closer inspection.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / f. Übermensch
Caesar and Napoleon point to the future, when they pursue their task regardless of human sacrifice [Nietzsche]
     Full Idea: In nature's such as Caesar and Napoleon we intuit something of a 'disinterested' laboring on one's marble, regardless of any sacrifice of human beings. The future of the highest human beings lies on here: to bear responsibility and not collapse under it.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 1[056])
     A reaction: Hideous. Nietzsche at his absolute worst. You would think there was some wonderful higher good to which they were leading the human race, when they just strike me as people who liked fighting, and adored winning.
Napoleon was very focused, and rightly ignored compassion [Nietzsche]
     Full Idea: With Napoleon only the essential instincts of humanity came into consideration during his calculations, and he had a right not to take notice of the exceptional ones e.g. of compassion.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[131])
     A reaction: Napoleon was notoriously indifferent to casualties, and I find it depressing that Nietzsche supports him. Napoleon brought misery to Europe for nearly twenties, mainly because he loved winning battles. Nothing über about that.
23. Ethics / F. Existentialism / 2. Nihilism
For the strongest people, nihilism gives you wings! [Nietzsche]
     Full Idea: In the hands of the strongest every kind of pessimism and nihilism becomes only one more hammer and tool with which one mounts a new pair of wings on oneself.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 2[101])
     A reaction: Not sure how this works. Why is great strength needed? Strength implies forceful overcoming. The wings come from rejecting nihilism, but why does that need strength? Aren't there people with wings who never even thought of nihilism?
24. Political Theory / B. Nature of a State / 1. Purpose of a State
The great question is approaching, of how to govern the earth as a whole [Nietzsche]
     Full Idea: It is approaching, irrefutably, hesitatingly, terrible as fate, the great task and fate: how should the earth as a whole be governed?
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 37[08])
     A reaction: Two issues have accelerated the question, though we have yet to properly face it. One is the incredible increase in military destructiveness, and other is the damage to the planet caused by the relentless pursuit of wealth.
24. Political Theory / C. Ruling a State / 2. Leaders / d. Elites
The controlling morality of aristocracy is the desire to resemble their ancestors [Nietzsche]
     Full Idea: The foundation of all aristocracies …is to resemble the ancestors as much as possible, which serves as the controlling morality: mourning at the thought of change and variation.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 35[22])
     A reaction: This makes sense of the permanent residence of the family, full of portraits and family trees. Aristocrats preserve records of their predecessors, in a way that most of us don't, going back before grandparents.
24. Political Theory / D. Ideologies / 14. Nationalism
People feel united as a nation by one language, but then want a common ancestry and history [Nietzsche]
     Full Idea: People who speak one language and read the same newspapers today call themselves 'nations', and also want much too eagerly to be of common ancestry and history.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[203])
     A reaction: This sort of nationalism is still with us, as white supremacy, and as history as mythology. But we can't just shake off a sense of which gene pools we come from, and which lines of history are our personal inheritance.
25. Social Practice / C. Rights / 4. Property rights
To be someone you need property, and wanting more is healthy [Nietzsche]
     Full Idea: Property owners are to a man of one belief: 'you have to own something to be something'. But this is the oldest and healthiest of all instincts: I would add 'you have to want more than you have in order to become more'.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 37[11])
     A reaction: An odd idea from someone who spent his later years living in one room in a guest house. The context of this is a rejection of socialism. The love of and need for property and possessions must be taken into account in any politics.
26. Natural Theory / C. Causation / 2. Types of cause
Causation can be seen in counterfactual terms, or as increased probability, or as energy flow [Crane]
     Full Idea: A theory of causation might say 'If A had not existed, B would not have existed' (counterfactual theory), or 'B is more likely if A occurs' (probabilistic), or 'energy flows from A to B'.
     From: Tim Crane (Elements of Mind [2001], 2.11)
     A reaction: As always, it is vital to separate epistemology from ontology. Energy won't cover agents. Whisper "Fire!" in a theatre.
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
Causes are properties, not events, because properties are what make a difference in a situation [Crane]
     Full Idea: My view is that causes are properties (not events); when we look for causes, we look for the aspect of a situation which made a difference, and aspects are properties or qualities.
     From: Tim Crane (Elements of Mind [2001], 2.14)
     A reaction: He is talking about explanations, which may not be causes, or at least they have a different emphasis. Don't events 'make a difference'? Events are ontologically weird
26. Natural Theory / D. Laws of Nature / 11. Against Laws of Nature
Laws of nature are actually formulas of power relations [Nietzsche]
     Full Idea: The alleged 'laws of nature' are formulas for power relationships…
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[247])
     A reaction: Love it. This is precisely the powers ontology of modern philosophy of science. His Will to Power is not often recognised as closely related to this view.
27. Natural Reality / B. Modern Physics / 4. Standard Model / a. Concept of matter
'Gunk' is an individual possessing no parts that are atoms [Chihara]
     Full Idea: An 'atomless gunk' is defined to be an individual possessing no parts that are atoms.
     From: Charles Chihara (A Structural Account of Mathematics [2004], App A)
     A reaction: [Lewis coined it] If you ask what are a-toms made of and what are ideas made of, the only answer we can offer is that the a-toms are made of gunk, and the ideas aren't made of anything, which is still bad news for the existence of ideas.
27. Natural Reality / F. Chemistry / 1. Chemistry
In chemistry every substance pushes, and thus creates new substances [Nietzsche]
     Full Idea: In chemistry is revealed that every substance pushes its force as far as it can, then a third something emerges.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[51])
     A reaction: This is the ontology of powers as the basis of science, of which I am a fan. It is Nietzsche's Will to Power in action, which is often mistakenly taken to only refer to human affairs.
28. God / B. Proving God / 2. Proofs of Reason / a. Ontological Proof
It seems that 'exists' could sometimes be a predicate [Crane]
     Full Idea: The view that 'exists' is never a predicate is not plausible.
     From: Tim Crane (Elements of Mind [2001], 1.7)
     A reaction: He doesn't enlarge. Russell says 'exists' is a quantifier. 'Your very existence offends me - I hope it is confiscated'.
