1. Philosophy / A. Wisdom / 3. Wisdom Deflated
But what is the reasoning of the body, that it requires the wisdom you seek? [Nietzsche]
     Full Idea: There is more reason in your body than in your best wisdom. For who knows for what purpose your body requires precisely your best wisdom?
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 1.05)
     A reaction: Lovely question. For years I've paid lip-service to wisdom as the rough aim of all philosophy. Not quite knowing what wisdom is doesn't bother me, but knowing why I want wisdom certainly does, especially after this idea.
1. Philosophy / D. Nature of Philosophy / 8. Humour
Reject wisdom that lacks laughter [Nietzsche]
     Full Idea: Let that wisdom be false to us that brought no laughter with it!
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 3.12.23)
3. Truth / A. Truth Problems / 7. Falsehood
To love truth, you must know how to lie [Nietzsche]
     Full Idea: Inability to lie is far from being love of truth. ....He who cannot lie does not know what truth is.
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 4.13.9)
5. Theory of Logic / A. Overview of Logic / 3. Value of Logic
Logicians acknowledge too few things, while others acknowledge too many [Fitzralph]
     Full Idea: Those who have been well trained in logic err in recognising too few things, whereas others who are ignorant of logic ascribe to every statement a new entity, postulating more entities than God has ever established as real.
     From: Richard Fitzralph (Sentences [1328], II.1.2), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 22.3
7. Existence / E. Categories / 4. Category Realism
Causality indicates which properties are real [Cartwright,N]
     Full Idea: Causality is a clue to what properties are real.
     From: Nancy Cartwright (How the Laws of Physics Lie [1983], 9.3)
     A reaction: An interesting variant on the Shoemaker proposal that properties actually are causal. I'm not sure that there is anything more to causality that the expression in action of properties, which I take to be powers. Structures are not properties.
14. Science / D. Explanation / 2. Types of Explanation / a. Types of explanation
Two main types of explanation are by causes, or by citing a theoretical framework [Cartwright,N]
     Full Idea: In explaining a phenomenon one can cite the causes of that phenomenon; or one can set the phenomenon in a general theoretical framework.
     From: Nancy Cartwright (How the Laws of Physics Lie [1983], 4.1)
     A reaction: The thing is, you need to root an explanation in something taken as basic, and theoretical frameworks need further explanation, whereas causes seem to be basic.
14. Science / D. Explanation / 2. Types of Explanation / c. Explanations by coherence
An explanation is a model that fits a theory and predicts the phenomenological laws [Cartwright,N]
     Full Idea: To explain a phenomenon is to find a model that fits it into the basic framework of the theory and that thus allows us to derive analogues for the messy and complicated phenomenological laws that are true of it.
     From: Nancy Cartwright (How the Laws of Physics Lie [1983], 8.3)
     A reaction: This summarises the core of her view in this book. She is after models rather than laws, and the models are based on causes.
14. Science / D. Explanation / 2. Types of Explanation / e. Lawlike explanations
The covering law view assumes that each phenomenon has a 'right' explanation [Cartwright,N]
     Full Idea: The covering-law account supposes that there is, in principle, one 'right' explanation for each phenomenon.
     From: Nancy Cartwright (How the Laws of Physics Lie [1983], Intro)
     A reaction: Presumably the law is held to be 'right', but there must be a bit of flexibility in describing the initial conditions, and the explanandum itself.
Laws get the facts wrong, and explanation rests on improvements and qualifications of laws [Cartwright,N]
     Full Idea: We explain by ceteris paribus laws, by composition of causes, and by approximations that improve on what the fundamental laws dictate. In all of these cases the fundamental laws patently do not get the facts right.
     From: Nancy Cartwright (How the Laws of Physics Lie [1983], Intro)
     A reaction: It is rather headline-grabbing to say in this case that laws do not get the facts right. If they were actually 'wrong' and 'lied', there wouldn't be much point in building explanations on them.
Laws apply to separate domains, but real explanations apply to intersecting domains [Cartwright,N]
     Full Idea: When different kinds of causes compose, we want to explain what happens in the intersection of different domains. But the laws we use are designed only to tell truly what happens in each domain separately.
     From: Nancy Cartwright (How the Laws of Physics Lie [1983], Intro)
     A reaction: Since presumably the laws are discovered through experiments which try to separate out a single domain, in those circumstances they actually are true, so they don't 'lie'.
Covering-law explanation lets us explain storms by falling barometers [Cartwright,N]
     Full Idea: Much criticism of the original covering-law model objects that it lets in too much. It seems we can explain Henry's failure to get pregnant by his taking birth control pills, and we can explain the storm by the falling barometer.
     From: Nancy Cartwright (How the Laws of Physics Lie [1983], 2.0)
     A reaction: I take these examples to show that true explanations must be largely causal in character. The physicality of causation is what matters, not 'laws'. I'd say the same of attempts to account for causation through counterfactuals.
I disagree with the covering-law view that there is a law to cover every single case [Cartwright,N]
     Full Idea: Covering-law theorists tend to think that nature is well-regulated; in the extreme, that there is a law to cover every case. I do not.
     From: Nancy Cartwright (How the Laws of Physics Lie [1983], 2.2)
     A reaction: The problem of coincidence is somewhere at the back of this thought. Innumerable events have their own explanations, but it is hard to explain their coincidence (see Aristotle's case of bumping into a friend in the market).
You can't explain one quail's behaviour by just saying that all quails do it [Cartwright,N]
     Full Idea: 'Why does that quail in the garden bob its head up and down in that funny way whenever it walks?' …'Because they all do'.
     From: Nancy Cartwright (How the Laws of Physics Lie [1983], 3.5)
     A reaction: She cites this as an old complaint against the covering-law model of explanation. It captures beautifully the basic error of the approach. We want to know 'why', rather than just have a description of the pattern. 'They all do' is useful information.
14. Science / D. Explanation / 3. Best Explanation / c. Against best explanation
In science, best explanations have regularly turned out to be false [Cartwright,N]
     Full Idea: There are a huge number of cases in the history of science where we now know our best explanations were false.
     From: Nancy Cartwright (How the Laws of Physics Lie [1983], 5.3)
     A reaction: [She cites Laudan 1981 for this] The Ptolemaic system and aether are the standard example cited for this. I believe strongly in the importance of best explanation. Only a fool would just accept the best explanation available. Coherence is needed.
16. Persons / B. Nature of the Self / 7. Self and Body / a. Self needs body
The powerful self behind your thoughts and feelings is your body [Nietzsche]
     Full Idea: Behind your thoughts and feelings stands a powerful commander, an unknown wise man - he is called a self. He lives in your body; he is your body.
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], I.4), quoted by Kevin Aho - Existentialism: an introduction 5 'Creature'
     A reaction: I find Nietzsche's view of the self very congenial, though I tend to see the self as certain central functions of the brain. The brain is enmeshed in the body (as in the location of pains).
16. Persons / D. Continuity of the Self / 3. Reference of 'I'
Forget the word 'I'; 'I' is performed by the intelligence of your body [Nietzsche]
     Full Idea: You say 'I' and you are proud of this word. But greater than this - although you will not believe in it - is your body and its great intelligence, which does not say 'I' but performs 'I'.
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 1.05)
     A reaction: I'm not sure if I understand this, but I offer it as a candidate for the most profound idea ever articulated about personal identity.
20. Action / B. Preliminaries of Action / 2. Willed Action / a. Will to Act
The will is constantly frustrated by the past [Nietzsche]
     Full Idea: Powerless against that which has been done, the will is an angry spectator of all things past. The will cannot will backwards; that it cannot break time and time's desire - that is the will's most lonely affliction.
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 2.20)
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / d. Biological ethics
We created meanings, to maintain ourselves [Nietzsche]
     Full Idea: Man first implanted values into things to maintain himself - he first created the meaning of things, a human meaning!
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 1.16)
     A reaction: It is certainly hard to see anything resembling values or meaning in the cosmos, if you remove the human beings. We should expect an evolutionary grounding in their explanation.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / f. Übermensch
The noble man wants new virtues; the good man preserves what is old [Nietzsche]
     Full Idea: The noble man wants to create new things and a new virtue. The good man wants the old things and that the old things shall be preserved.
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 1.09)
     A reaction: There is a limit to how many plausible virtues the noble men can come up with. We may already have run out. Are we going to have to re-run the Iliad?
22. Metaethics / B. Value / 2. Values / g. Love
We only really love children and work [Nietzsche]
     Full Idea: One loves from the very heart only one's child and one's work.
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 3.03)
     A reaction: Very Nietzchean (and masculine?) to cite one's work. Rachmaninov said he was 85% musician and 15% human being, so I guess he loved music from the very heart.
22. Metaethics / C. The Good / 2. Happiness / c. Value of happiness
I want my work, not happiness! [Nietzsche]
     Full Idea: Do I aspire after happiness? I aspire after my work!
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 4.20)
     A reaction: I empathise with aspiring to do something, rather than be something. But what do we wish for our children? Happiness first, then achievement?
23. Ethics / C. Virtue Theory / 3. Virtues / a. Virtues
Virtues can destroy one another, through jealousy [Nietzsche]
     Full Idea: Every virtue is jealous of the others, and jealousy is a terrible thing. Even virtues can be destroyed through jealousy.
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 1.07)
     A reaction: How much more subtle and plausible than the picture of accumulating virtues, like medals! Zarathustra says it is best to have just one virtue.
23. Ethics / C. Virtue Theory / 4. External Goods / c. Wealth
People now find both wealth and poverty too much of a burden [Nietzsche]
     Full Idea: Nobody grows rich or poor any more: both are too much of a burden.
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 1.01)
     A reaction: True. Most people I know are just puzzled by people who actually seem to want to be extremely wealthy.
23. Ethics / C. Virtue Theory / 4. External Goods / d. Friendship
If you want friends, you must be a fighter [Nietzsche]
     Full Idea: If you want a friend, you must be willing to wage war for him: and to wage war, you must be capable of being an enemy.
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 1.15)
23. Ethics / F. Existentialism / 2. Nihilism
The greatest experience possible is contempt for your own happiness, reason and virtue [Nietzsche]
     Full Idea: What is the greatest thing you can experience? It is the hour of the great contempt. The hour in which even your happiness grows loathsome to you, and your reason and your virtue also.
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 1.01)
     A reaction: This would be a transient state for Nietzsche, in which you realise the hollowness of those traditional ideas, and begin to seek something else.
24. Political Theory / A. Basis of a State / 1. A People / c. A unified people
An enduring people needs its own individual values [Nietzsche]
     Full Idea: No people could live without evaluating; but if it wishes to maintain itself it must not evaluate as its neighbour evaluates.
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 1.16)
     A reaction: Political philosophers say plenty about a 'people', but little about what unifies them, or about what keeps one people distinct from another. Most people's are proud of their local values.
24. Political Theory / B. Nature of a State / 3. Constitutions
The state coldly claims that it is the people, but that is a lie [Nietzsche]
     Full Idea: The state is the coldest of all cold monsters. Coldly it lies, too; and this lie creeps from its mouth: 'I, the state, am the people'. It is a lie!
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 1.12)
     A reaction: This strikes me as just as true even after everyone gets the vote. Rulers can't help gradually forgetting about the people.
25. Social Practice / A. Freedoms / 5. Freedom of lifestyle
Saints want to live as they desire, or not to live at all [Nietzsche]
     Full Idea: 'To live as I desire to live or not to live at all': that is what I want, that is what the most saintly man wants.
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 4.09)
     A reaction: [spoken by Zarathustra]
25. Social Practice / D. Justice / 3. Punishment / b. Retribution for crime
Whenever we have seen suffering, we have wanted the revenge of punishment [Nietzsche]
     Full Idea: The spirit of revenge: my friends, that, up to now, has been mankind's chief concern; and where there was suffering, there was always supposed to be punishment.
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 2.20)
25. Social Practice / F. Life Issues / 5. Sexual Morality
Man and woman are deeply strange to one another! [Nietzsche]
     Full Idea: Who has fully conceived how strange man and woman are to one another!
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 3.10.2)
26. Natural Theory / C. Causation / 8. Particular Causation / e. Probabilistic causation
A cause won't increase the effect frequency if other causes keep interfering [Cartwright,N]
     Full Idea: A cause ought to increase the frequency of the effect, but this fact may not show up in the probabilities if other causes are at work.
     From: Nancy Cartwright (How the Laws of Physics Lie [1983], 1.1)
     A reaction: [She cites Patrick Suppes for this one] Presumably in experimental situations you can weed out the interference, but that threatens to eliminate mere 'probability' entirely.
26. Natural Theory / D. Laws of Nature / 2. Types of Laws
There are fundamental explanatory laws (false!), and phenomenological laws (regularities) [Cartwright,N, by Bird]
     Full Idea: Nancy Cartwright distinguishes between 'fundamental explanatory laws', which we should not believe, and 'phenomenological laws', which are regularities established on the basis of observation.
     From: report of Nancy Cartwright (How the Laws of Physics Lie [1983]) by Alexander Bird - Philosophy of Science Ch.4
     A reaction: The distinction is helpful, so that we can be clearer about what everyone is claiming. We can probably all agree on the phenomenological laws, which are epistemological. Personally I claim truth for the best fundamental explanatory laws.
Laws of appearances are 'phenomenological'; laws of reality are 'theoretical' [Cartwright,N]
     Full Idea: Philosophers distinguish phenomenological from theoretical laws. Phenomenological laws are about appearances; theoretical ones are about the reality behind the appearances.
     From: Nancy Cartwright (How the Laws of Physics Lie [1983], Intro)
     A reaction: I'm suspecting that Humeans only really believe in the phenomenological kind. I'm only interested in the theoretical kind, and I take inference to the best explanation to be the bridge between the two. Cartwright rejects the theoretical laws.
26. Natural Theory / D. Laws of Nature / 4. Regularities / b. Best system theory
Good organisation may not be true, and the truth may not organise very much [Cartwright,N]
     Full Idea: There is no reason to think that the principles that best organise will be true, nor that the principles that are true will organise much.
     From: Nancy Cartwright (How the Laws of Physics Lie [1983], 2.5)
     A reaction: This is aimed at the Mill-Ramsey-Lewis account of laws, as axiomatisations of the observed patterns in nature.
26. Natural Theory / D. Laws of Nature / 11. Against Laws of Nature
There are few laws for when one theory meets another [Cartwright,N]
     Full Idea: Where theories intersect, laws are usually hard to come by.
     From: Nancy Cartwright (How the Laws of Physics Lie [1983], 2.3)
     A reaction: There are attempts at so-called 'bridge laws', to get from complex theories to simple ones, but her point is well made about theories on the same 'level'.
To get from facts to equations, we need a prepared descriptions suited to mathematics [Cartwright,N]
     Full Idea: To get from a detailed factual knowledge of a situation to an equation, we must prepare the description of the situation to meet the mathematical needs of the theory.
     From: Nancy Cartwright (How the Laws of Physics Lie [1983], Intro)
     A reaction: She is clearly on to something here, as Galileo is blatantly wrong in his claim that the book of nature is written in mathematics. Mathematics is the best we can manage in getting a grip on the chaos.
Simple laws have quite different outcomes when they act in combinations [Cartwright,N]
     Full Idea: For explanation simple laws must have the same form when they act together as when they act singly. ..But then what the law states cannot literally be true, for the consequences that occur if it acts alone are not what occurs when they act in combination.
     From: Nancy Cartwright (How the Laws of Physics Lie [1983], 3.6)
     A reaction: This is Cartwright's basic thesis. Her point is that the laws 'lie', because they claim to predict a particular outcome which never ever actually occurs. She says we could know all the laws, and still not be able to explain anything.
28. God / A. Divine Nature / 2. Divine Nature
I can only believe in a God who can dance [Nietzsche]
     Full Idea: I should believe only in a God who understood how to dance.
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 1.08)
28. God / C. Attitudes to God / 5. Atheism
There can't be gods, because that leaves us nothing to create! [Nietzsche]
     Full Idea: If there were gods, how could I endure not to be a god! Therefore there are no gods. ...For what would there be to create if gods - existed!
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 2.02)
     A reaction: [Zarathustra says this, not Nietzsche!]
29. Religion / D. Religious Issues / 2. Immortality / d. Heaven
We don't want heaven; now that we are men, we want the kingdom of earth [Nietzsche]
     Full Idea: We certainly do not want to enter into the kingdom of heaven: we have become men, so we want the kingdom of earth.
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 4.18.2)
Heaven was invented by the sick and the dying [Nietzsche]
     Full Idea: It was the sick and dying who despised the body and the earth and invented the things of heaven and the redeeming drops of blood.
     From: Friedrich Nietzsche (Thus Spake Zarathustra [1884], 1.04)
