80 ideas

1. Philosophy / D. Nature of Philosophy / 1. Philosophy
Nietzsche thinks philosophy makes us more profound, but not better [Nietzsche, by Ansell Pearson]
     Full Idea: Nietzsche does not think philosopher exists to make us better human beings - but it can make us more profound ones.
     From: report of Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885]) by Keith Ansell Pearson - How to Read Nietzsche Intro
     A reaction: What is the point of being more 'profound' if that isn't 'better'? Are we sure that Kant is more 'profound' than a Yanomamo Indian? Personally I think philosophy tends to produce moral improvement, but I have seen a few striking counterexamples.
1. Philosophy / D. Nature of Philosophy / 7. Despair over Philosophy
How many mediocre thinkers are occupied with influential problems! [Nietzsche]
     Full Idea: It is a terrible thought to contemplate that an immense number of mediocre thinkers are occupied with really influential matters.
     From: Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885]), quoted by Rüdiger Safranski - Nietzsche: a philosophical biography 03
     A reaction: [in a journal of 1867] What would he say now, with the plethora of academics and students aspiring to the highest levels of human thought? If I face up to the fact that I am 'mediocre', should I stop? And become mediocre at something else?
1. Philosophy / E. Nature of Metaphysics / 2. Possibility of Metaphysics
Your metaphysics is 'cheating' if your ontology won't support the beliefs you accept [Sider]
     Full Idea: Ontological 'cheaters' are those ne'er-do-well metaphysicians (such as presentists, phenomenalists, or solipsists) who refuse to countenance a sufficiently robust conception of the fundamental to underwrite the truths they accept.
     From: Theodore Sider (Writing the Book of the World [2011], 08.4)
     A reaction: Presentists are placed in rather insalubrious company here, The notion of 'cheaters' is nice, and I associate it with Australian philosophy, and the reason that was admired by David Lewis.
1. Philosophy / E. Nature of Metaphysics / 4. Metaphysics as Science
Metaphysics is not about what exists or is true or essential; it is about the structure of reality [Sider]
     Full Idea: Metaphysics, at bottom, is about the fundamental structure of reality. Not about what's necessarily true. Not about what properties are essential. Not about conceptual analysis. Not about what there is. Structure.
     From: Theodore Sider (Writing the Book of the World [2011], 01)
     A reaction: The opening words of his book. I take them to be absolutely correct, and to articulate the new orthodoxy about metaphysics which has emerged since about 1995. He expands this as being about patterns, categories and joints.
Extreme doubts about metaphysics also threaten to undermine the science of unobservables [Sider]
     Full Idea: The most extreme critics of metaphysics base their critique on sweeping views about language (logical positivism), or knowledge (empiricism), ...but this notoriously threatens the science of unobservables as much as it threatens metaphysics.
     From: Theodore Sider (Writing the Book of the World [2011], 05.1)
     A reaction: These criticisms also threaten speculative physics (even about what is possibly observable).
1. Philosophy / E. Nature of Metaphysics / 6. Metaphysics as Conceptual
Nietzsche has a metaphysics, as well as perspectives - the ontology is the perspectives [Nietzsche, by Richardson]
     Full Idea: Nietzsche's thought includes both a metaphysics and a perspectivism, once these are more complexly grasped. But I argue that the metaphysics is basic: it's an ontology of perspectives.
     From: report of Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885]) by John Richardson - Nietzsche's System Intro
     A reaction: Very good. If it was just gormless relativism, which is what many people hope for in Nietzsche, why is it many perspectives? If they are just relative, having lots of them is no help. The point is they sum, and increase verisimilitude.
It seems unlikely that the way we speak will give insights into the universe [Sider]
     Full Idea: It has always seemed odd that insight into the fundamental workings of the universe should be gained by reflection on how we think and speak.
     From: Theodore Sider (Writing the Book of the World [2011], 07.8)
     A reaction: A nice expression of what should by now be obvious to all philosophers - that analysis of language is not going to reveal very much. It is merely clearing the undergrowth so that we can go somewhere.
1. Philosophy / F. Analytic Philosophy / 4. Conceptual Analysis
Conceptual analysts trust particular intuitions much more than general ones [Sider]
     Full Idea: Conceptual analysts generally regard intuitive judgements about particular cases as being far more diagnostic than intuitive judgements about general principles.
     From: Theodore Sider (Writing the Book of the World [2011], 02.4 n7)
     A reaction: Since I take the aim to be the building up an accurate picture about general truths, it would be daft to just leap to our intuitions about those general truths. Equally you can't cut intuition out of the picture (pace Ladyman).
2. Reason / A. Nature of Reason / 7. Status of Reason
Reason is just another organic drive, developing late, and fighting for equality [Nietzsche]
     Full Idea: Reason is a support organ that slowly develops itself, ...and emancipates itself slowly to equal rights with the organic drives - so that reason (belief and knowledge) fights with the drives, as itself a new drive, very late come to preponderance.
     From: Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885], 9/11[243]), quoted by John Richardson - Nietzsche's System 4.3.2 n55
     A reaction: A very powerful and fascinating idea. There is a silly post-modern tendency to think that Nietzsche denegrates and trivialises reason because of remarks like this, but he takes ranking the drives to be the supreme activity. I rank reason high.
2. Reason / D. Definition / 13. Against Definition
It seems possible for a correct definition to be factually incorrect, as in defining 'contact' [Sider]
     Full Idea: Arguably, 'there is absolutely no space between two objects in contact' is false, but definitional of 'contact'. ...We need a word for true definitional sentences. I propose: 'analytic'.
     From: Theodore Sider (Writing the Book of the World [2011], 09.8)
Philosophical concepts are rarely defined, and are not understood by means of definitions [Sider]
     Full Idea: Philosophical concepts of interest are rarely reductively defined; still more rarely does our understanding of such concepts rest on definitions. ...(We generally understand concepts to the extent that we know what role they play in thinking).
     From: Theodore Sider (Writing the Book of the World [2011], 02.1)
     A reaction: I'm not sure that I agree with this. I suspect that Sider has the notion of definition in mind that is influenced by lexicography. Aristotle's concept of definition I take to be lengthy and expansive, and that is very relevant to philosophy.
3. Truth / A. Truth Problems / 3. Value of Truth
We don't care about plain truth, but truth in joint-carving terms [Sider]
     Full Idea: What we care about is truth in joint-carving terms, not just truth.
     From: Theodore Sider (Writing the Book of the World [2011], 04.5)
     A reaction: The thought is that it matters what conceptual scheme is used to express the truth (the 'ideology'). Truths can be true but uninformative or unexplanatory.
3. Truth / B. Truthmakers / 5. What Makes Truths / b. Objects make truths
Orthodox truthmaker theories make entities fundamental, but that is poor for explanation [Sider]
     Full Idea: According to the entrenched truthmaker theorist, the fundamental facts consist just of facts citing the existence of entities. It's hard to see how all the complexity we experience could possibly be explained from that sparse basis.
     From: Theodore Sider (Writing the Book of the World [2011], 08.5)
     A reaction: This may be the 'entrenched' truthmaker view, but it is not clear why there could not be more complicated fundamental truthmakers, with structure as well as entities. And powers.
4. Formal Logic / D. Modal Logic ML / 7. Barcan Formula
The Barcan schema implies if X might have fathered something, there is something X might have fathered [Sider]
     Full Idea: If we accept the Barcan and converse Barcan schemas, this leads to surprising ontological consequences. Wittgenstein might have fathered something, so, by the Barcan schema, there is something that Wittgenstein might have fathered.
     From: Theodore Sider (Writing the Book of the World [2011], 11.9)
     A reaction: [He cites Tim Williamson for this line of thought] I was liking the Barcan picture, by now I am backing away fast. They cannot be serious!
4. Formal Logic / E. Nonclassical Logics / 7. Paraconsistency
Our dislike of contradiction in logic is a matter of psychology, not mathematics [Brouwer]
     Full Idea: Not to the mathematician, but to the psychologist, belongs the task of explaining why ...we are averse to so-called contradictory systems in which the negative as well as the positive of certain propositions are valid.
     From: Luitzen E.J. Brouwer (Intuitionism and Formalism [1912], p.79)
     A reaction: Was the turning point of Graham Priest's life the day he read this sentence? I don't agree. I take the principle of non-contradiction to be a highly generalised observation of how the world works (and Russell agrees with me).
4. Formal Logic / G. Formal Mereology / 1. Mereology
'Gunk' is an object in which proper parts all endlessly have further proper parts [Sider]
     Full Idea: An object is 'gunky' if each of its parts has further proper parts; thus gunk involves infinite descent in the part-whole relation.
     From: Theodore Sider (Writing the Book of the World [2011], 07.11.2)
4. Formal Logic / G. Formal Mereology / 3. Axioms of Mereology
Which should be primitive in mereology - part, or overlap? [Sider]
     Full Idea: Should our fundamental theory of part and whole take 'part' or 'overlap' as primitive?
     From: Theodore Sider (Writing the Book of the World [2011], 02.3)
5. Theory of Logic / A. Overview of Logic / 1. Overview of Logic
There is a real issue over what is the 'correct' logic [Sider]
     Full Idea: Certain debates over the 'correct' logic are genuine, and not linguistic or conceptual.
     From: Theodore Sider (Writing the Book of the World [2011], 01.3)
     A reaction: It is rather hard to give arguments in favour of this view, but I am pleased to have the authority of Sider with me.
'It is raining' and 'it is not raining' can't be legislated, so we can't legislate 'p or ¬p' [Sider]
     Full Idea: I cannot legislate-true 'It is raining' and I cannot legislate true 'It is not raining', so if I cannot legislate either true then I cannot legislate-true the disjunction 'it is raining or it is not raining'.
     From: Theodore Sider (Writing the Book of the World [2011], 06.5)
     A reaction: This strikes me as a very simple and very persuasive argument against the idea that logic is a mere convention. I take disjunction to be an abstract summary of how the world works. Sider seems sympathetic.
5. Theory of Logic / A. Overview of Logic / 6. Classical Logic
Classical logic is good for mathematics and science, but less good for natural language [Sider]
     Full Idea: Despite its brilliant success in mathematics and fundamental science, classical logic applies uneasily to natural language.
     From: Theodore Sider (Writing the Book of the World [2011], 10.6)
     A reaction: He gives examples of the conditional, and debates over the meaning of 'and', 'or' and 'not', and also names and quantifiers. Many modern philosophical problems result from this conflict.
5. Theory of Logic / B. Logical Consequence / 1. Logical Consequence
Modal accounts of logical consequence are simple necessity, or essential use of logical words [Sider]
     Full Idea: The simplest modal account is that logical consequence is just necessary consequence; another modal account says that logical consequences are modal consequences that involve only logical words essentially.
     From: Theodore Sider (Writing the Book of the World [2011], 12.3)
     A reaction: [He cites Quine's 'Carnap and Logical Truth' for the second idea] Sider is asserting that Humeans like him dislike modality, and hence need a nonmodal account of logical consequence.
5. Theory of Logic / E. Structures of Logic / 2. Logical Connectives / a. Logical connectives
Define logical constants by role in proofs, or as fixed in meaning, or as topic-neutral [Sider]
     Full Idea: Some say that logical constants are those expressions that are defined by their proof-theoretic roles, others that they are the expressions whose semantic values are permutation-invariant, and still others that they are the topic-neutral expressions.
     From: Theodore Sider (Writing the Book of the World [2011], 10.3)
     A reaction: [He cites MacFarlane 2005 as giving a survey of this]
5. Theory of Logic / H. Proof Systems / 4. Natural Deduction
'Tonk' is supposed to follow the elimination and introduction rules, but it can't be so interpreted [Sider]
     Full Idea: 'Tonk' is stipulated by Prior to stand for a meaning that obeys the elimination and introduction rules; but there simply is no such meaning; 'tonk' cannot be interpreted so as to obey the rules.
     From: Theodore Sider (Writing the Book of the World [2011], 06.5)
     A reaction: 'Tonk' thus seems to present a problem for so-called 'natural' deduction, if the natural deduction consists of nothing more than obey elimination and introduction rules.
6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / g. Applying mathematics
Scientific laws largely rest on the results of counting and measuring [Brouwer]
     Full Idea: A large part of the natural laws introduced by science treat only of the mutual relations between the results of counting and measuring.
     From: Luitzen E.J. Brouwer (Intuitionism and Formalism [1912], p.77)
     A reaction: His point, I take it, is that the higher reaches of numbers have lost touch with the original point of the system. I now see the whole issue as just depending on conventions about the agreed extension of the word 'number'.
6. Mathematics / C. Sources of Mathematics / 10. Constructivism / b. Intuitionism
Intuitionists only accept denumerable sets [Brouwer]
     Full Idea: The intuitionist recognises only the existence of denumerable sets.
     From: Luitzen E.J. Brouwer (Intuitionism and Formalism [1912], p.80)
     A reaction: That takes you up to omega, but not beyond, presumably because it then loses sight of the original intuition of 'bare two-oneness' (Idea 12453). I sympathise, but the word 'number' has shifted its meaning a lot these days.
Neo-intuitionism abstracts from the reuniting of moments, to intuit bare two-oneness [Brouwer]
     Full Idea: Neo-intuitionism sees the falling apart of moments, reunited while remaining separated in time, as the fundamental phenomenon of human intellect, passing by abstracting to mathematical thinking, the intuition of bare two-oneness.
     From: Luitzen E.J. Brouwer (Intuitionism and Formalism [1912], p.80)
     A reaction: [compressed] A famous and somewhat obscure idea. He goes on to say that this creates one and two, and all the finite ordinals.
7. Existence / C. Structure of Existence / 5. Supervenience / a. Nature of supervenience
Supervenience is a modal connection [Sider]
     Full Idea: Supervenience is just a kind of modal connection.
     From: Theodore Sider (Writing the Book of the World [2011], 09.10)
     A reaction: It says what would happen, as well as what does. This is big for Sider because he rejects modality as a feature of actuality. I think the world is crammed full of modal facts, so supervenience should be a handy tool for me.
7. Existence / C. Structure of Existence / 6. Fundamentals / b. Types of fundamental
Is fundamentality in whole propositions (and holistic), or in concepts (and atomic)? [Sider]
     Full Idea: The locus of fundamentality for a Finean is the whole proposition, whereas for me it is the proposition-part. Fundamentality is holistic for the Finean, atomistic for me.
     From: Theodore Sider (Writing the Book of the World [2011], 08.3)
     A reaction: This is because Kit Fine has pushed fundamentality into a relation (grounding), rather than into the particular entities involved (if I understand Sider's reading of him aright). My first intuition is to side with Sider. I'm on Sider's side...
Tables and chairs have fundamental existence, but not fundamental natures [Sider]
     Full Idea: The existence of tables and chairs is just as fundamental as the existence of electrons (in contrast, perhaps, with smirks and shadows, which do not exist fundamentally). However, tables and chairs have nonfundamental natures.
     From: Theodore Sider (Writing the Book of the World [2011], 08.7)
     A reaction: This seems to be a good clarification, and to me the 'nature' of something points towards its essence. However, I suppose he refers here to the place of something in a dependence hierarchy. But then, why does it have that place? What power?
7. Existence / C. Structure of Existence / 8. Stuff / a. Pure stuff
Unlike things, stuff obeys unrestricted composition and mereological essentialism [Sider]
     Full Idea: Stuff obeys unrestricted composition and mereological essentialism, whereas things do not.
     From: Theodore Sider (Writing the Book of the World [2011], 09.6.2)
     A reaction: [He cites Markosian 2004]
7. Existence / D. Theories of Reality / 5. Naturalism
First see nature as non-human, then fit ourselves into this view of nature [Nietzsche]
     Full Idea: My task is the dehumanisation of nature, and then the naturalisation of humanity once it has attained the pure concept of 'nature'.
     From: Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885], 9.525), quoted by Rüdiger Safranski - Nietzsche: a philosophical biography 10
     A reaction: Safranski sees this as summarising Nietzsche's project, and it could be a mission statement for naturalism. This idea pinpoints why I take Nietzsche to be important - as a pioneer of the naturalistic view of people.
7. Existence / D. Theories of Reality / 9. States of Affairs
We must distinguish 'concrete' from 'abstract' and necessary states of affairs. [Sider]
     Full Idea: The truthmaker theorist's 'concrete' states of affairs must be distinguished from necessarily existing 'abstract' states of affairs.
     From: Theodore Sider (Writing the Book of the World [2011], 08.4)
     A reaction: [He cites Plantinga's 'Nature of Necessity' for the second one; I presume the first one is Armstrong]
7. Existence / D. Theories of Reality / 11. Ontological Commitment / d. Commitment of theories
Accept the ontology of your best theory - and also that it carves nature at the joints [Sider]
     Full Idea: We can add to the Quinean advice to believe the ontology of your best theory that you should also regard the ideology of your best theory as carving at the joints.
     From: Theodore Sider (Writing the Book of the World [2011], 02.3)
     A reaction: I've never liked the original Quinean formulation, but this is much better. I just take my ontological commitments to reside in me, not in whatever theory I am currently employing. I may be dubious about my own theory.
8. Modes of Existence / B. Properties / 3. Types of Properties
A property is intrinsic if an object alone in the world can instantiate it [Sider]
     Full Idea: Chisholm and Kim proposed a modal notion of an 'intrinsic' property - that a property is intrinsic if and only if it is possibly instantiated by an object that is alone in the world.
     From: Theodore Sider (Writing the Book of the World [2011], 01.2)
     A reaction: [He cites Chisholm 1976:127 and Kim 1982:59-60] Sider then gives a counterexample from David Lewis (Idea 14979).
8. Modes of Existence / B. Properties / 10. Properties as Predicates
Predicates can be 'sparse' if there is a universal, or if there is a natural property or relation [Sider]
     Full Idea: For Armstrong a predicate is sparse when there exists a corresponding universal; for Lewis, a predicate is sparse when there exists a corresponding natural property or relation.
     From: Theodore Sider (Writing the Book of the World [2011], 06)
     A reaction: I like 'sparse' properties, but have no sympathy with Armstrong, and am cautious about Lewis. I like Shoemaker's account, which makes properties even sparser. 'Abundant' so-called properties are my pet hate. They are 'predicates'!
8. Modes of Existence / C. Powers and Dispositions / 1. Powers
Storms are wonderful expressions of free powers! [Nietzsche]
     Full Idea: How different the lightning, the storm, the hail, free powers, without ethics! How happy, how powerful they are, pure will, untarnished by intellect!
     From: Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885], 2.122), quoted by Rüdiger Safranski - Nietzsche: a philosophical biography 02
     A reaction: Nietzsche was a perfect embodiment of the Romantic Movement! I take this to be a deep observation, since I think raw powers are the most fundamental aspect of nature. Schopenhauer is behind this idea.
9. Objects / D. Essence of Objects / 3. Individual Essences
We begin with concepts of kinds, from individuals; but that is not the essence of individuals [Nietzsche]
     Full Idea: The overlooking of individuals gives us the concept and with this our knowledge begins: in categorising, in the setting up of kinds. But the essence of things does not correspond to this.
     From: Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885], p.51)
     A reaction: [dated c1873] Aha! So Nietzsche agrees with me in my defence of individual essences, against kind essences (which seem to me to obviously derive from the nature of individuals). Deep in my heart I knew I would find this quotation one day.
9. Objects / D. Essence of Objects / 15. Against Essentialism
Essence (even if nonmodal) is not fundamental in metaphysics [Sider]
     Full Idea: We should not regard nonmodal essence as being metaphysically basic: fundamental theories need essence no more than they need modality.
     From: Theodore Sider (Writing the Book of the World [2011], 12.1)
     A reaction: He is discussing Kit Fine, and notes that Fine offers a nonmodal view of essence, but still doesn't make it fundamental. I am a fan of essences, but making them fundamental in metaphysics seems unlikely.
10. Modality / C. Sources of Modality / 1. Sources of Necessity
Humeans say that we decide what is necessary [Sider]
     Full Idea: The spirit of Humeanism is that necessity is not a realm to be discovered. We draw the lines around what is necessary.
     From: Theodore Sider (Writing the Book of the World [2011], 12.3)
     A reaction: I disagree, but it is hard to argue the point. My intuitions are that the obvious necessities of logic and mathematics reflect the way nature has to be. The deepest necessities are patterns (about which God has no choice).
Modal terms in English are entirely contextual, with no modality outside the language [Sider]
     Full Idea: English modals are context-dependent through and through; there is no stable 'outer modality'.
     From: Theodore Sider (Writing the Book of the World [2011], 12.7)
     A reaction: Sider has been doing so well up to here. To me this is swallowing the bait of linguistic approaches to philosophy which he has fought so hard to avoid.
10. Modality / C. Sources of Modality / 3. Necessity by Convention
If truths are necessary 'by convention', that seems to make them contingent [Sider]
     Full Idea: If □φ says that φ is true by convention, then □φ would apparently turn out to be contingent, since statements about what conventions we adopt are not themselves true by convention. The main axioms of S4 and S5 would be false.
     From: Theodore Sider (Writing the Book of the World [2011], 12.1)
Conventionalism doesn't seem to apply to examples of the necessary a posteriori [Sider]
     Full Idea: Conventionalism is apparently inapplicable to Kripke's and Putnam's examples of the necessary a posteriori (and, relatedly, to de re modality).
     From: Theodore Sider (Writing the Book of the World [2011], 12.1)
     A reaction: [Sidelle 1989 discusses this]
10. Modality / C. Sources of Modality / 4. Necessity from Concepts
Humeans says mathematics and logic are necessary because that is how our concept of necessity works [Sider]
     Full Idea: Why are logical (or mathematical, or analytic...) truths necessary? The Humean's answer is that this is just how our concept of necessity works.
     From: Theodore Sider (Writing the Book of the World [2011], 12.11)
     A reaction: This is why I (unlike Sider) am not a Humean. If we agreed that 'necessary' meant 'whatever is decreed by the Pope', that would so obviously not be necessary that we would have to start searching nature for true necessities.
10. Modality / C. Sources of Modality / 5. Modality from Actuality
The world does not contain necessity and possibility - merely how things are [Sider]
     Full Idea: At bottom, the world is an amodal place. Necessity and possibility do not carve at the joints; ultimate reality is not 'full of threats and promises' (Goodman). The book of the world says how things are, not how they must or might be.
     From: Theodore Sider (Writing the Book of the World [2011], 12)
     A reaction: Nice to see this expressed so clearly. I find it much easier to disagree with as a result. At first blush I would say that if you haven't noticed that the world is full of threats and promises, you should wake up and smell the coffee. Actuality is active.
14. Science / B. Scientific Theories / 2. Aim of Science
A theory which doesn't fit nature is unexplanatory, even if it is true [Sider]
     Full Idea: 'Theories' based on bizarre, non-joint-carving classifications are unexplanatory even when true.
     From: Theodore Sider (Writing the Book of the World [2011], 03.1)
     A reaction: This nicely pinpoints why I take explanation to be central to whole metaphysical enterprise.
14. Science / B. Scientific Theories / 8. Ramsey Sentences
If I used Ramsey sentences to eliminate fundamentality from my theory, that would be a real loss [Sider]
     Full Idea: If the entire theory of this book were replaced by its Ramsey sentence, omitting all mention of fundamentality, something would seem to be lost.
     From: Theodore Sider (Writing the Book of the World [2011], 02.2 n2)
     A reaction: It is a moot point whether Ramsey sentences actually eliminate anything from the ontology, but trying to wriggle out of ontological commitment looks a rather sad route to follow.
14. Science / C. Induction / 5. Paradoxes of Induction / a. Grue problem
Problem predicates in induction don't reflect the structure of nature [Sider]
     Full Idea: 'Is nonblack', 'is a nonraven', and 'grue' fail to carve at the joints.
     From: Theodore Sider (Writing the Book of the World [2011], 03.3)
     A reaction: A lot more than this needs to said, but this remark encapsulates why I find most of these paradoxes of induction uninteresting. They are all the creations of logicians, rather than of scientists.
Two applications of 'grue' do not guarantee a similarity between two things [Sider]
     Full Idea: The applicability of 'grue' to each of a pair of particulars does not guarantee the similarity of those particulars.
     From: Theodore Sider (Writing the Book of the World [2011], 06.2)
     A reaction: Grue is not a colour but a behaviour. If two things are 'mercurial' or 'erratic', will that ensure a similarity at any given moment?
14. Science / C. Induction / 6. Bayes's Theorem
Bayes produces weird results if the prior probabilities are bizarre [Sider]
     Full Idea: In the Bayesian approach, bizarre prior probability distributions will result in bizarre responses to evidence.
     From: Theodore Sider (Writing the Book of the World [2011], 03.3)
     A reaction: This is exactly what you find when people with weird beliefs encounter ridiculous evidence for things. It doesn't invalidate the formula, but just says rubbish in rubbish out.
14. Science / D. Explanation / 1. Explanation / a. Explanation
Explanations must cite generalisations [Sider]
     Full Idea: Explanations must cite generalisations.
     From: Theodore Sider (Writing the Book of the World [2011], 07.13)
     A reaction: I'm uneasy about this. Presumably some events have a unique explanation - a unique mechanism, perhaps. Language is inescapably general in its nature - which I take to be Aristotle's reason for agreeing the Sider. [Sider adds mechanisms on p.159]
14. Science / D. Explanation / 3. Best Explanation / b. Ultimate explanation
If the ultimate explanation is a list of entities, no laws, patterns or mechanisms can be cited [Sider]
     Full Idea: Ultimate explanations always terminate in the citation of entities; but since a mere list of entities is so unstructured, these 'explanations' cannot be systematized with detailed general laws, patterns, or mechanisms.
     From: Theodore Sider (Writing the Book of the World [2011], 08.5)
     A reaction: We just need to distinguish between ultimate ontology and ultimate explanations. I think explanations peter out at the point where we descend below the mechanisms. Patterns or laws don't explain on their own. Causal mechanisms are the thing.
15. Nature of Minds / B. Features of Minds / 4. Intentionality / a. Nature of intentionality
Intentionality is too superficial to appear in the catalogue of ultimate physics [Sider]
     Full Idea: One day the physicists will complete the catalogue of ultimate and irreducible properties of things. When they do, the like of spin, charm and charge will perhaps appear on the list. But aboutness sure won't; intentionality simply doesn't go that deep.
     From: Theodore Sider (Writing the Book of the World [2011], 4 Intro)
     A reaction: Fodor's project is to give a reductive, and perhaps eliminative, account of intentionality of mind, while leaving open what one might do with the phenomenological aspects. Personally I don't think they will appear on the list either.
19. Language / A. Nature of Meaning / 5. Meaning as Verification
Intuitonists in mathematics worried about unjustified assertion, as well as contradiction [Brouwer, by George/Velleman]
     Full Idea: The concern of mathematical intuitionists was that the use of certain forms of inference generates, not contradiction, but unjustified assertions.
     From: report of Luitzen E.J. Brouwer (Intuitionism and Formalism [1912]) by A.George / D.J.Velleman - Philosophies of Mathematics Ch.6
     A reaction: This seems to be the real origin of the verificationist idea in the theory of meaning. It is a hugely revolutionary idea - that ideas are not only ruled out of court by contradiction, but that there are other criteria which should also be met.
19. Language / A. Nature of Meaning / 6. Meaning as Use
Prior to conventions, not all green things were green? [Sider]
     Full Idea: It is absurd to say that 'before we introduced our conventions, not all green things were green'.
     From: Theodore Sider (Writing the Book of the World [2011], 06.5)
     A reaction: Well… Different cultures label the colours of the rainbow differently, and many of them omit orange. I suspect the blue/green borderline has shifted.
19. Language / E. Analyticity / 2. Analytic Truths
Conventions are contingent and analytic truths are necessary, so that isn't their explanation [Sider]
     Full Idea: To suggest that analytic truths make statements about linguistic conventions is a nonstarter; statements about linguistic conventions are contingent, whereas the statements made by typical analytic sentences are necessary.
     From: Theodore Sider (Writing the Book of the World [2011], 06.5)
     A reaction: That 'anything yellow is extended' is not just a convention should be fairly obvious, and it is obviously necessary. But we can say that bachelors are necessarily unmarried men - given the current convention.
19. Language / E. Analyticity / 4. Analytic/Synthetic Critique
Analyticity has lost its traditional role, which relied on truth by convention [Sider]
     Full Idea: Nothing can fully play the role traditionally associated with analyticity, for much of that traditional role presupposed the doctrine of truth by convention.
     From: Theodore Sider (Writing the Book of the World [2011], 09.8)
     A reaction: Sider rejects Quine's attack on analyticity, but accepts his critique of truth by convention.
20. Action / A. Definition of Action / 1. Action Theory
Nietzsche classified actions by the nature of the agent, not the nature of the act [Nietzsche, by Foot]
     Full Idea: Nietzsche thought profoundly mistaken a taxonomy that classified actions as the doing of this or that, insisting that the true nature of an action depended rather on the nature of the individual who did it.
     From: report of Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885], 7) by Philippa Foot - Natural Goodness 7
     A reaction: This is more in the spirit of Aristotle than in the modern legalistic style. It seems to totally ignore consequences, which would puzzle victims or beneficiaries of the action.
20. Action / C. Motives for Action / 4. Responsibility for Actions
Nietzsche failed to see that moral actions can be voluntary without free will [Foot on Nietzsche]
     Full Idea: To threaten morality Nietzsche needed to show not only that free will was an illusion, but also that no other distinction between voluntary and involuntary action (Aristotle's, for instance) would do instead. He seems to be wrong about this.
     From: comment on Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885], 7) by Philippa Foot - Natural Goodness
     A reaction: Just the idea I have been seeking! There is no free will, so in what way are we responsible? Simple: we are responsible for any act which can be shown to be voluntary. It can't just be any action we fully caused, because of accidents.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / e. Human nature
Each person has a fixed constitution, which makes them a particular type of person [Nietzsche, by Leiter]
     Full Idea: Nietzsche's view (which we may call the 'Doctrine of Types') is that each person has a fixed psycho-physical constitution, which defines him as a particular type of person.
     From: report of Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885]) by Brian Leiter - Nietzsche On Morality 1 'What kind'
     A reaction: An interestesting variant, standing between the Aristotelian picture of one shared human nature, and the existentialist picture of our endlessly malleable nature. So what type am I, and what type are you? How many types are there?
Nietzsche could only revalue human values for a different species [Nietzsche, by Foot]
     Full Idea: It is only for a different species that Nietzsche's most radical revaluation of values could be valid. It is not valid for us as we are, or are ever likely to be.
     From: report of Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885]) by Philippa Foot - Natural Goodness 7
     A reaction: This is the Aristotelian view, that our values and virtues arise out of our human nature, with which I largely agree, though we should resist its rather conservative tendencies.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / f. Übermensch
The superman is a monstrous oddity, not a serious idea [MacIntyre on Nietzsche]
     Full Idea: The Übermensch belongs in the pages of a philosophical bestiary rather than in serious discussion.
     From: comment on Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885]) by Alasdair MacIntyre - After Virtue: a Study in Moral Theory Ch.2
     A reaction: It may just be an empirical and historical fact that the value-systems of a culture arise from the characters of a few strong-willed and charismatic individuals, rather than from collective need - let along collective philosophising.
Nietzsche's higher type of man is much more important than the idealised 'superman' [Nietzsche, by Leiter]
     Full Idea: The 'superman' has received far more attention from commentators than it warrants: the higher type of human being (a Goethe or a Nietzsche) is much more important than the hyperbolic, and often obscure, Zarathustrian rhetoric about the über-mensch.
     From: report of Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885]) by Brian Leiter - Nietzsche On Morality 4 'Higher' n2
     A reaction: Leiter says the über-mensch idea almost entirely drops out of Nietzsche's mature work.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / g. Will to power
The 'will to power' is basically applied to drives and forces, not to people [Nietzsche, by Richardson]
     Full Idea: 'Will to power' is most basically applied not to people but to 'drives' or 'forces', simpler units which Nietzsche sometimes calls 'points' and 'power quanta'.
     From: report of Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885], 1) by John Richardson - Nietzsche's System 1
     A reaction: This strikes as a correct account of Nietzsche, and a hugely important interpretative point. He wasn't saying that all human beings would conquer the world if they could. The point is there are many conflicting and combining wills to power.
22. Metaethics / B. Value / 2. Values / g. Love
Friendly chats undermine my philosophy; wanting to be right at the expense of love is folly [Nietzsche]
     Full Idea: My entire philosophy wavers after just an hour of friendly conversation with complete strangers. It strikes me as so foolish to insist on being right at the expense of love.
     From: Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885], 6.37), quoted by Rüdiger Safranski - Nietzsche: a philosophical biography 09
     A reaction: [Letter to Gast, 1880] Strangers who met Nietzsche on walks reported how kind and friendly he was. Most people want to be right most of the time, but a few people have this vice in rather excessive form. Especially philosophers!
23. Ethics / C. Virtue Theory / 1. Virtue Theory / c. Particularism
Moral generalisation is wrong, because we should evaluate individual acts [Nietzsche, by Foot]
     Full Idea: Nietzsche believed that moral generalisation was impossible because the proper subject of evaluation was, instead, a person's individual act.
     From: report of Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885]) by Philippa Foot - Nietzsche's Immoralism p.155
     A reaction: This suggests a different type of particularism, focusing on the particular decision, rather than on the details of the situation. Presumable no two moral decisions are ever sufficiently the same to be compared. But a lie is a lie.
23. Ethics / C. Virtue Theory / 1. Virtue Theory / d. Virtue theory critique
Nietzsche thought our psychology means there can't be universal human virtues [Nietzsche, by Foot]
     Full Idea: Nietzsche believed, in effect, that as the facts of human psychology really were, there could be no such thing as human virtues, dispositions good in any man.
     From: report of Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885]) by Philippa Foot - Nietzsche's Immoralism p.157
     A reaction: Presumably each individual can only have virtues appropriate to their individual nature, which is something like channelling their personal psychological drives. Can't we each have our individual version of courage or honesty?
23. Ethics / F. Existentialism / 1. Existentialism
Nietzsche tried to lead a thought-provoking life [Safranski on Nietzsche]
     Full Idea: All of us ponder our existences, but Nietzsche strove to lead the kind of life that would yield food for thought.
     From: comment on Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885], 01) by Rüdiger Safranski - Nietzsche: a philosophical biography 01
     A reaction: Could Nietzsche possibly be a role model for us in this respect? If I were starting afresh, guided by this thought, I'm not sure how I would go about it. It is Nietzsche's astonishing independence of thought that hits you.
23. Ethics / F. Existentialism / 2. Nihilism
Initially nihilism was cosmic, but later Nietzsche saw it as a cultural matter [Nietzsche, by Ansell Pearson]
     Full Idea: Nietzsche's first presentation of nihilism is an existential affair arising from cosmic problems, but he later stressed nihilism as a historical and cultural problem of values, where mankind's highest values reach a point of devaluation.
     From: report of Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885]) by Keith Ansell Pearson - How to Read Nietzsche Ch.1
     A reaction: The second version seems to imply a quasi-Marxist determinism about social progress. Then you would have to ask, what is the point of fighting against it? I wonder if Nietzsche's values are anti-nihilist, but his metaethics makes nihilism unavoidable?
Nietzsche urges that nihilism be active, and will nothing itself [Nietzsche, by Zizek]
     Full Idea: Nietzsche opposes active to passive nihilism - it is better to actively will nothing itself than not to will anything.
     From: report of Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885]) by Slavoj Zizek - Conversations, with Glyn Daly §3
     A reaction: To 'actively will nothing' sounds to me indistinguishable from suicide, which I don't believe was ever on Nietzsche's agenda. It is hard, though, to disentangle Nietzsche's attitude to nihilism.
23. Ethics / F. Existentialism / 4. Boredom
Flight from boredom leads to art [Nietzsche]
     Full Idea: Flight from boredom is the mother of all art.
     From: Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885], 8.432), quoted by Rüdiger Safranski - Nietzsche: a philosophical biography Intro
     A reaction: I might even say that all human achievement comes from boredom.
23. Ethics / F. Existentialism / 7. Existential Action
Nietzsche was fascinated by a will that can turn against itself [Nietzsche, by Safranski]
     Full Idea: Nietzsche was fascinated by the idea of a will that turns against itself, against its usual impulses.
     From: report of Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885]) by Rüdiger Safranski - Nietzsche: a philosophical biography 03
     A reaction: This strikes me as very existentialist - a case of existence before essence.
23. Ethics / F. Existentialism / 8. Eternal Recurrence
Reliving life countless times - this gives the value back to life which religion took away [Nietzsche]
     Full Idea: "Is this something I want to do countless times?" ....Let us etch the image of eternity onto our own lives! This thought embodies more than all religions, which taught us to disdain life as something ephemeral and to look toward an unspecified other life.
     From: Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885], 9.496,503), quoted by Rüdiger Safranski - Nietzsche: a philosophical biography 10
     A reaction: You can't get away from eternal recurrence being an imaginative trick, to focus value onto our choices. For a while Nietzsche tried to persuade himself that the recurrence actually occurred, but we all know it doesn't.
24. Political Theory / B. Nature of a State / 1. Purpose of a State
Individual development is more important than the state, but a community is necessary [Nietzsche]
     Full Idea: All states and communities are something lower than the individual, but necessary kinds for his higher development.
     From: Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885], 10/7[98]), quoted by John Richardson - Nietzsche's System 2.4 n104
     A reaction: This indicates why Nietzsche should not really be taken as a political thinker, though I would say there is a sort of communitarianism implied in this, just as for Aristotle virtue is supreme, which needs social expression.
24. Political Theory / B. Nature of a State / 4. Citizenship
Nietzsche thinks we should join a society, in order to criticise, heal and renew it [Nietzsche, by Richardson]
     Full Idea: Nietzsche thinks the best way of both joining and opposing a society is to find where it's sick, to be its merciless critic and exposer, and to help heal and renew it.
     From: report of Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885]) by John Richardson - Nietzsche's System 3.3
     A reaction: This sounds like the great Victorian sages, such as Ruskin and Arnold. Christopher Hitchens was a nice recent example. Maybe these have been the finest British citizens?
24. Political Theory / B. Nature of a State / 5. Culture
Every culture loses its identity and power if it lacks a major myth [Nietzsche]
     Full Idea: Without myth every culture loses its natural healthy creating power: only a horizon encircled with myths can mark off a cultural movement as a discrete unit.
     From: Friedrich Nietzsche (Works (refs to 8 vol Colli and Montinari) [1885], 1.145)
     A reaction: In the early part of his career this was a big idea for Nietzsche, especially associated with Wagner's Ring, but he moved away from the idea later.
26. Natural Theory / D. Laws of Nature / 11. Against Laws of Nature
Many of the key theories of modern physics do not appear to be 'laws' [Sider]
     Full Idea: That spacetime is 4D Lorentzian manifold, that the universe began with a singularity, and in a state of low entropy, are all central to physics, but it is a stretch to call them 'laws'. ...It has been argued that there are no laws of biology.
     From: Theodore Sider (Writing the Book of the World [2011], 03.1)
The notion of law doesn't seem to enhance physical theories [Sider]
     Full Idea: Adding the notion of law to physical theory doesn't seem to enhance its explanatory power.
     From: Theodore Sider (Writing the Book of the World [2011], 02.4)
     A reaction: I agree with his scepticism about laws, although Sider offers it as part of his scepticism about modal facts being included in explanations of actuality. Personally I like dispositions, but not laws. See the ideas of Stephen Mumford.
27. Natural Reality / C. Space / 4. Substantival Space
Space has real betweenness and congruence structure (though it is not the Euclidean concepts) [Sider]
     Full Idea: In metaphysics, space is intrinsically structured; the genuine betweenness and congruence relations are privileged in a way that Euclidean-betweenness and Euclidean-congruence are not.
     From: Theodore Sider (Writing the Book of the World [2011], 03.4)
     A reaction: I note that Einstein requires space to be 'curved', which implies that it is a substance with properties.
27. Natural Reality / C. Space / 6. Space-Time
The central question in the philosophy of time is: How alike are time and space? [Sider]
     Full Idea: The central question in the philosophy of time is: How alike are time and space?
     From: Theodore Sider (Writing the Book of the World [2011], 11.1)
27. Natural Reality / D. Time / 1. Nature of Time / f. Eternalism
The spotlight theorists accepts eternal time, but with a spotlight of the present moving across it [Sider]
     Full Idea: The spotlight theorist accepts the block universe, but also something in addition: a joint-carving monadic property of presentness, which is possessed by just one moment of time, and which 'moves', to be possessed by later and later times.
     From: Theodore Sider (Writing the Book of the World [2011], 11.9)
     A reaction: This seems better than the merely detached eternalist view, which seems to ignore the key phenomenon. I just can't comprehend any theory which makes the future as real as the past.
