1. Philosophy / B. History of Ideas / 4. Early European Thought
Judging by the positive forces, the Renaissance was the last great age [Nietzsche]
     Full Idea: Ages are to be assessed by their positive forces - and by this assessment the age of the Renaissance, so prodigal and so fateful, appears as the last great age.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.37)
     A reaction: I suspect that Nietzsche places art very high among the positive forces. Science and technology showed barely a glimmer during the Renaissance. Mathematics moved very little, Copernicus was ignored, and logic was static.
1. Philosophy / C. History of Philosophy / 2. Ancient Philosophy / b. Pre-Socratic philosophy
I revere Heraclitus [Nietzsche]
     Full Idea: I set apart with high reverence the name of Heraclitus.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.2)
1. Philosophy / C. History of Philosophy / 2. Ancient Philosophy / c. Classical philosophy
Thucydides was the perfect anti-platonist sophist [Nietzsche]
     Full Idea: My recreation, my preference, my cure from all Platonism has always been Thucydides. …Sophist culture, by which I mean realist culture, attains in him its perfect expression.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 9.2)
1. Philosophy / D. Nature of Philosophy / 1. Philosophy
Thinking has to be learned in the way dancing has to be learned [Nietzsche]
     Full Idea: Thinking has to be learned in the way dancing has to be learned.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 7.7)
     A reaction: Nice. At its deepest level thinking isn't a rational process?
1. Philosophy / E. Nature of Metaphysics / 3. Metaphysical Systems
Wanting a system in philosophy is a lack of integrity [Nietzsche]
     Full Idea: I mistrust all systematizers and avoid them. The will to system is a lack of integrity.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], Maxim 26)
2. Reason / A. Nature of Reason / 7. Status of Reason
I want to understand the Socratic idea that 'reason equals virtue equals happiness' [Nietzsche]
     Full Idea: I seek to understand out of what idiosyncrasy that Socratic equation 'reason equals virtue equals happiness' derives.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.04)
2. Reason / C. Styles of Reason / 1. Dialectic
With dialectics the rabble gets on top [Nietzsche]
     Full Idea: With dialectics the rabble gets on top.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.05)
2. Reason / E. Argument / 6. Conclusive Proof
Anything which must first be proved is of little value [Nietzsche]
     Full Idea: What has first to have itself proved is of little value.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.05)
4. Formal Logic / A. Syllogistic Logic / 2. Syllogistic Logic
'Equivocation' is when terms do not mean the same thing in premises and conclusion [Beall/Restall]
     Full Idea: 'Equivocation' is when the terms do not mean the same thing in the premises and in the conclusion.
     From: JC Beall / G Restall (Logical Consequence [2005], Intro)
5. Theory of Logic / A. Overview of Logic / 4. Pure Logic
Formal logic is invariant under permutations, or devoid of content, or gives the norms for thought [Beall/Restall]
     Full Idea: Logic is purely formal either when it is invariant under permutation of object (Tarski), or when it has totally abstracted away from all contents, or it is the constitutive norms for thought.
     From: JC Beall / G Restall (Logical Consequence [2005], 2)
     A reaction: [compressed] The third account sounds rather woolly, and the second one sounds like a tricky operation, but the first one sounds clear and decisive, so I vote for Tarski.
5. Theory of Logic / B. Logical Consequence / 2. Types of Consequence
Logical consequence needs either proofs, or absence of counterexamples [Beall/Restall]
     Full Idea: Technical work on logical consequence has either focused on proofs, where validity is the existence of a proof of the conclusions from the premises, or on models, which focus on the absence of counterexamples.
     From: JC Beall / G Restall (Logical Consequence [2005], 3)
5. Theory of Logic / B. Logical Consequence / 4. Semantic Consequence |=
Logical consequence is either necessary truth preservation, or preservation based on interpretation [Beall/Restall]
     Full Idea: Two different views of logical consequence are necessary truth-preservation (based on modelling possible worlds; favoured by Realists), or truth-preservation based on the meanings of the logical vocabulary (differing in various models; for Anti-Realists).
     From: JC Beall / G Restall (Logical Consequence [2005], 2)
     A reaction: Thus Dummett prefers the second view, because the law of excluded middle is optional. My instincts are with the first one.
5. Theory of Logic / B. Logical Consequence / 8. Material Implication
A step is a 'material consequence' if we need contents as well as form [Beall/Restall]
     Full Idea: A logical step is a 'material consequence' and not a formal one, if we need the contents as well as the structure or form.
     From: JC Beall / G Restall (Logical Consequence [2005], 2)
5. Theory of Logic / I. Semantics of Logic / 3. Logical Truth
A 'logical truth' (or 'tautology', or 'theorem') follows from empty premises [Beall/Restall]
     Full Idea: If a conclusion follows from an empty collection of premises, it is true by logic alone, and is a 'logical truth' (sometimes a 'tautology'), or, in the proof-centred approach, 'theorems'.
     From: JC Beall / G Restall (Logical Consequence [2005], 4)
     A reaction: These truths are written as following from the empty set Φ. They are just implications derived from the axioms and the rules.
5. Theory of Logic / J. Model Theory in Logic / 1. Logical Models
Models are mathematical structures which interpret the non-logical primitives [Beall/Restall]
     Full Idea: Models are abstract mathematical structures that provide possible interpretations for each of the non-logical primitives in a formal language.
     From: JC Beall / G Restall (Logical Consequence [2005], 3)
6. Mathematics / B. Foundations for Mathematics / 2. Proof in Mathematics
Hilbert proofs have simple rules and complex axioms, and natural deduction is the opposite [Beall/Restall]
     Full Idea: There are many proof-systems, the main being Hilbert proofs (with simple rules and complex axioms), or natural deduction systems (with few axioms and many rules, and the rules constitute the meaning of the connectives).
     From: JC Beall / G Restall (Logical Consequence [2005], 3)
7. Existence / A. Nature of Existence / 3. Being / e. Being and nothing
The 'real being' of things is a nothingness constructed from contradictions in the actual world [Nietzsche]
     Full Idea: The characteristics which have been assigned to the 'real being' of things are the characteristics of non-being, of nothingness - the 'real world has been constructed out of the contradiction of the actual world.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.6)
     A reaction: I take this to be a critique of Hegel, in particular. Could we describe the metaphysics of Nietzsche as 'constructivist'? I certainly think he is underrated as a metaphysician, because the ideas are so fragmentary.
7. Existence / A. Nature of Existence / 3. Being / h. Dasein (being human)
We get the concept of 'being' from the concept of the 'ego' [Nietzsche]
     Full Idea: Being is everywhere thought in, foisted on, as cause; it is only from the conception 'ego' that there follows, derivatively, the concept 'being'.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.5)
     A reaction: 'Being' is such a remote abstraction that I doubt whether we can say anything at all meaningful about where it 'comes from'.
7. Existence / C. Structure of Existence / 2. Reduction
Good reductionism connects fields of knowledge, but doesn't replace one with another [Pinker]
     Full Idea: Good reductionism (also called 'hierarchical reductionism') consists not of replacing one field of knowledge with another, but of connecting or unifying them.
     From: Steven Pinker (The Blank Slate [2002], Ch.4)
     A reaction: A nice simple clarification. In this sense I am definitely a reductionist about mind (indeed, about everything). There is nothing threatening to even 'spiritual' understanding by saying that it is connected to the brain.
7. Existence / D. Theories of Reality / 4. Anti-realism
The grounds for an assertion that the world is only apparent actually establish its reality [Nietzsche]
     Full Idea: The grounds upon which 'this' world has been designated as apparent establish rather its reality - another kind of reality is absolutely undemonstrable.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.6)
9. Objects / A. Existence of Objects / 6. Nihilism about Objects
In language we treat 'ego' as a substance, and it is thus that we create the concept 'thing' [Nietzsche]
     Full Idea: It is the metaphysics of language (that is, of reason) ....which believes in the 'ego', in the ego as being, in the ego as substance, and which projects its belief in the ego-substance on to all things - only thus does it create the concept 'thing'.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.5)
12. Knowledge Sources / B. Perception / 6. Inference in Perception
The evidence of the senses is falsified by reason [Nietzsche]
     Full Idea: 'Reason' is the cause of our falsification of the evidence of the senses.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.1)
     A reaction: One for McDowell.
12. Knowledge Sources / D. Empiricism / 2. Associationism
Connectionists say the mind is a general purpose learning device [Pinker]
     Full Idea: Connectionists do not, of course, believe that the mind is a blank slate, but they do believe in the closest mechanistic equivalent, a general purpose learning device.
     From: Steven Pinker (The Blank Slate [2002], Ch.5)
     A reaction: This shows the closeness of connectionism to Hume's associationism (Idea 2189), which was just a minimal step away from Locke's mind as 'white paper' (Idea 7507). Pinker is defending 'human nature', but connectionism has a point.
12. Knowledge Sources / E. Direct Knowledge / 4. Memory
Is memory stored in protein sequences, neurons, synapses, or synapse-strengths? [Pinker]
     Full Idea: Are memories stored in protein sequences, in new neurons or synapses, or in changes in the strength of existing synapses?
     From: Steven Pinker (The Blank Slate [2002], Ch.5)
     A reaction: This seems to be a neat summary of current neuroscientific thinking about memory. If you are thinking that memory couldn't possibly be so physical, don't forget the mind-boggling number of events involved in each tiny memory. See Idea 6668.
14. Science / D. Explanation / 4. Explanation Doubts / b. Rejecting explanation
Any explanation will be accepted as true if it gives pleasure and a feeling of power [Nietzsche]
     Full Idea: To trace something unknown back to something known is alleviating, soothing, gratifying and gives moreover a feeling of power. ...First principle: any explanation is better than none. ...Proof by pleasure ('by potency') as criterion of truth.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 5.5)
     A reaction: By 'proof by pleasure' he means that we find an explanation so satisfying that we cling to it. I assume it is a criterion of rationality (an epistemic virtue) to reject the principle 'any explanation is better than none'. Negative capability.
15. Nature of Minds / C. Capacities of Minds / 5. Generalisation by mind
The 'highest' concepts are the most general and empty concepts [Nietzsche]
     Full Idea: The 'highest concepts' ...are the most general, the emptiest concepts, the last fumes of evaporating reality.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.4)
     A reaction: This could be seen as an attack on the aspirations of all of philosophy, which seeks general truths out of the chaos of experience. Should we shut up, then, and just be and do?
16. Persons / E. Rejecting the Self / 2. Self as Social Construct
There are no 'individual' persons; we are each the sum of humanity up to this moment [Nietzsche]
     Full Idea: The 'individual' ...is an error: he does not constitute a separate entity, an atom, a 'link in the chain', something merely inherited from the past - he constitutes the entire single line 'man' up to and including himself.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.33)
     A reaction: I'm not sure I understand this, but you can sort of imagine yourself as a culmination of something, rather than as an isolated entity. I'm not sure how that is supposed to affect my behaviour.
16. Persons / F. Free Will / 5. Against Free Will
Roundworms live successfully with 302 neurons, so human freedom comes from our trillions [Pinker]
     Full Idea: The roundworm only has 959 cells, and 302 neurons in a fixed wiring diagram; it eats, mates, approaches and avoids certain smells, and that's about it. This makes it obvious that human 'free' behaviour comes from our complex biological makeup.
     From: Steven Pinker (The Blank Slate [2002], Ch.5)
     A reaction: I find this a persuasive example. Three hundred trillion neurons cannot possibly produce behaviour which is more than broadly predictable, and then it is the environment and culture that make it predictable, not the biology.
17. Mind and Body / E. Mind as Physical / 4. Connectionism
Neural networks can generalise their training, e.g. truths about tigers apply mostly to lions [Pinker]
     Full Idea: The appeal of neural networks is that they automatically generalize their training to similar new items. If one has been trained to think tigers eat frosted flakes, it will generalise that lions do too, because it knows tigers as sets of features.
     From: Steven Pinker (The Blank Slate [2002], Ch.5)
     A reaction: This certainly is appealing, because it offers a mechanistic account of abstraction and universals, which everyone agrees are central to proper thinking.
There are five types of reasoning that seem beyond connectionist systems [Pinker, by PG]
     Full Idea: Connectionist networks have difficulty with the kind/individual distinction (ducks/this duck), with compositionality (relations), with quantification (reference of 'all'), with recursion (embedded thoughts), and the categorical reasoning (exceptions).
     From: report of Steven Pinker (The Blank Slate [2002], Ch.5) by PG - Db (ideas)
     A reaction: [Read Pinker p.80!] These are essentially all the more sophisticated aspects of logical reasoning that Pinker can think of. Personally I would be reluctant to say a priori that connectionism couldn't cope with these things, just because they seem tough.
18. Thought / A. Modes of Thought / 5. Rationality / b. Human rationality
The fanatical rationality of Greek philosophy shows that they were in a state of emergency [Nietzsche]
     Full Idea: The fanaticism with which the whole of Greek thought throws itself at rationality betrays itself as a state of emergency: one was in peril, one had only one choice: either to perish or- be absurdly rational.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.10)
20. Action / B. Preliminaries of Action / 2. Willed Action / a. Will to Act
The big error is to think the will is a faculty producing effects; in fact, it is just a word [Nietzsche]
     Full Idea: At the beginning stands the great fateful error that the will is something which produces an effect - that will is a faculty.... Today we know it is merely a word.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.5)
     A reaction: This is despite Nietzsche's insistence that 'will to power' is the central fact of active existence. The misreading of Nietzsche is to think that this refers to the conscious exercising of a mental faculty.
20. Action / C. Motives for Action / 3. Acting on Reason / b. Intellectualism
The 'motive' is superficial, and may even hide the antecedents of a deed [Nietzsche]
     Full Idea: The so-called 'motive' is another error. Merely a surface phenomenon of consciousness - something alongside the deed which is more likely to cover up the antecedents of the deed than to represent them.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 6.3)
     A reaction: [Leiter gives 'VI.3', but I can't find it] As far as you can get from intellectualism about action, and is more in accord with the picture found in modern neuro-science. No one knows why they are 'interested' in something, and that's the start of it.
21. Aesthetics / A. Aesthetic Experience / 5. Natural Beauty
The beautiful never stands alone; it derives from man's pleasure in man [Nietzsche]
     Full Idea: Anyone who tried to divorce the beautiful from man's pleasure in man would at once feel the ground give way beneath him. The 'beautiful in itself' is not even a concept, merely a phrase.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.19)
     A reaction: I love the insult 'not even a concept'! It's like Pauli's 'not even wrong'!
21. Aesthetics / B. Nature of Art / 8. The Arts / a. Music
Without music life would be a mistake [Nietzsche]
     Full Idea: Without music life would be a mistake.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], Maxim 33)
     A reaction: Cf Schopenhauer in Idea 21469. If you, dear reader, don't love music, then I sincerely hope that there is something in your life which can match it.
22. Metaethics / A. Ethics Foundations / 1. Nature of Ethics / a. Preconditions for ethics
Healthy morality is dominated by an instinct for life [Nietzsche]
     Full Idea: All naturalism in morality, that is all healthy morality, is dominated by an instinct for life.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.4)
     A reaction: Sounds right. There is no reasoning against a moral nihilist, because they seem to have no instinct in favour of life. It is the given of morality.
22. Metaethics / A. Ethics Foundations / 1. Nature of Ethics / f. Ethical non-cognitivism
Philosophers hate values having an origin, and want values to be self-sufficient [Nietzsche]
     Full Idea: For philosophers, the higher must not be allowed to grow out of the lower, must not be allowed to have grown at all ...Moral: everything of the first rank must be causa sui. Origin in something else counts as an objection, as casting a doubt on value.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.4)
     A reaction: This is so deep and central that I wrote a paper on it, advocating that the theory of values should focus of value-makers.
There are no moral facts, and moralists believe in realities which do not exist [Nietzsche]
     Full Idea: An insight formulated by me: that there are no moral facts whatever. Moral judgement has this in common with religious judgement that it believes in realities which do not exist.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 6.1)
     A reaction: Not only a slogan for non-cognitivism, but also a clear statement of the error theory about morality, a century before John Mackie.
22. Metaethics / A. Ethics Foundations / 1. Nature of Ethics / g. Moral responsibility
The doctrine of free will has been invented essentially in order to blame and punish people [Nietzsche]
     Full Idea: The doctrine of will has been invented essentially for the purpose of punishment, that is of finding guilty.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 5.7)
     A reaction: Michael Frede says free will was invented to feel wholly in charge of our own actions. I doubt whether punishment was the first motive. The will just gives a simple explanation of actions.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / e. Human nature
Many think that accepting human nature is to accept innumerable evils [Pinker]
     Full Idea: To acknowledge human nature, many think, is to endorse racism, sexism, war, greed, genocide, nihilism, reactionary politics, and neglect of children and the disadvantaged.
     From: Steven Pinker (The Blank Slate [2002], Pref)
     A reaction: The point is that modern liberal thinking says everything is nurture (which can be changed), not nature (which can't). Virtue theory, of which I am a fan, requires a concept of human nature, as the thing which can attain excellence in its function.
22. Metaethics / B. Value / 2. Values / c. Life
The value of life cannot be estimated [Nietzsche]
     Full Idea: The value of life cannot be estimated.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.02)
     A reaction: Military leaders apparently judge that the death of one of their own soldiers is worth between 12 and 20 enemy deaths (so history suggests). How about ransom money?
When we establish values, that is life itself establishing them, through us [Nietzsche]
     Full Idea: When we speak of values we do so under the inspiration and from the perspective of life: life itself evaluates through us when we establish values
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.5)
     A reaction: I love Nietzsche's ideas about the source of values, and his remarks about the value of life. Other thinkers sound so simplistic in comparison.
In every age the wisest people have judged life to be worthless [Nietzsche]
     Full Idea: In every age the wisest have passed the identical judgement on life: it is worthless.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.01)
     A reaction: I guess he was having a bad day. Since the whole universe is clearly 'worthless', this judgement must in some sense be correct. But I love my books.
A philosopher fails in wisdom if he thinks the value of life is a problem [Nietzsche]
     Full Idea: For a philosopher to see a problem in the value of life thus even constitutes an objection to him, a question-mark as to his wisdom, a piece of unwisdom.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.02)
     A reaction: I take his point to be neither that life is unquestionably valuable nor that it is valueless, but that the very question is ridiculous. If we live, we value living. Sounds right.
Value judgements about life can never be true [Nietzsche]
     Full Idea: Judgements, value judgements concerning life, for or against it, can in the last resort never be true.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.02)
     A reaction: I suppose this is in the same spirit as judging whether celery tastes nice. Are you for or against the Moon?
To evaluate life one must know it, but also be situated outside of it [Nietzsche]
     Full Idea: One would have to be situated outside life ....[and yet know it thoroughly] ....to be permitted to touch on the problem of the value of life at all.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.5)
     A reaction: Can practising artists question the value of their art? The whole point of objectivity is that we can mentally step 'outside' of something, without actually withdrawing from it.
22. Metaethics / B. Value / 2. Values / g. Love
Love is the spiritualisation of sensuality [Nietzsche]
     Full Idea: The spiritualization of sensuality is called 'love': it is a great triumph over Christianity.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.3)
     A reaction: I'm not quite clear what 'spiritualization' means, particularly when it comes from Nietzsche.
22. Metaethics / C. The Good / 1. Goodness / d. Good as virtue
A good human will be virtuous because they are happy [Nietzsche]
     Full Idea: A well-constituted human being, a 'happy one', must perform certain actions and shrink from other actions. In a formula: his virtue is the consequence of his happiness.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 5.2)
     A reaction: A nice reversal of basic Aristotle, though Aristotle does say that the truly virtuous person is happy in their actions. Treat unhappy people with caution!
22. Metaethics / C. The Good / 2. Happiness / c. Value of happiness
Only the English actually strive after happiness [Nietzsche]
     Full Idea: Man does not strive after happiness; only the Englishman does that.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], Maxim 12)
     A reaction: The Danes keeping being voted the happiest nation, so presumably that results from some sort of effort on their part. The easiest is happiness is to achieve security, then do nothing.
23. Ethics / A. Egoism / 1. Ethical Egoism
A wholly altruistic morality, with no egoism, is a thoroughly bad thing [Nietzsche]
     Full Idea: An 'altruistic' morality, a morality under which egoism languishes - is under all circumstances a bad sign.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.35)
23. Ethics / C. Virtue Theory / 3. Virtues / d. Courage
Military idea: what does not kill me makes me stronger [Nietzsche]
     Full Idea: From the military school of life. - What does not kill me makes me stronger.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], Maxim 08)
     A reaction: The published version! Perhaps the most famous remark in all of Nietzsche, and no one realises it is ironic! It is a sarcastic remark about the battering ram mentality of the Prussian militarist! He had served in the army.
23. Ethics / C. Virtue Theory / 3. Virtues / f. Compassion
Invalids are parasites [Nietzsche]
     Full Idea: The invalid is a parasite on society.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.36)
     A reaction: I'll skip the rest, but you get the idea. The point (with which I sympathise) is that life is primarily about what healthy people do. Something has gone wrong if all we do is worry about the sick and the suffering.
24. Political Theory / D. Ideologies / 5. Democracy / f. Against democracy
Democracy is organisational power in decline [Nietzsche]
     Full Idea: Democracy has always been the declining form of the power to organise.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.39)
     A reaction: Even when Nietzsche is wrong (and who knows, here?) he always challenges you to think!
24. Political Theory / D. Ideologies / 6. Liberalism / g. Liberalism critique
The creation of institutions needs a determination which is necessarily anti-liberal [Nietzsche]
     Full Idea: For institutions to exist there must exist the kind of will, instinct, imperative which is anti-liberal to the point of malice: the will to tradition, to authority, to centuries-long responsibility, to solidarity between succeeding generations.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.39)
     A reaction: This sounds like a lovely challenge to Popper, who seems to have been a liberal who pinned his faith on institutions.
25. Social Practice / D. Justice / 1. Basis of justice
True justice is equality for equals and inequality for unequals [Nietzsche]
     Full Idea: 'Equality for equals, inequality for unequals' - that would be the true voice of justice.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.48)
25. Social Practice / E. Policies / 1. War / a. Just wars
To renounce war is to renounce the grand life [Nietzsche]
     Full Idea: One has renounced grand life when one renounces war.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.3)
     A reaction: Nietzsche was a medical orderly in the 1870 Franco-Prussian war, so he had seen it at first hand. I think the machine gun and the heavy bomber would have changed his attitude to warfare. He sounds a bit silly now. Nostalgia for the Iliad.
25. Social Practice / E. Policies / 5. Education / c. Teaching
There is a need for educators who are themselves educated [Nietzsche]
     Full Idea: There is a need for educators who are themselves educated.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 7.5)
25. Social Practice / F. Life Issues / 4. Suicide
Sometimes it is an error to have been born - but we can rectify it [Nietzsche]
     Full Idea: We have no power to prevent ourselves being born: but we can rectify this error - for sometimes it is an error.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.36)
26. Natural Theory / A. Speculations on Nature / 2. Natural Purpose / c. Purpose denied
'Purpose' is just a human fiction [Nietzsche]
     Full Idea: We invented the concept 'purpose': in reality purpose is lacking.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 5.8)
27. Natural Reality / G. Biology / 2. Life
In 1828, the stuff of life was shown to be ordinary chemistry, not a magic gel [Pinker]
     Full Idea: In 1828 Friedrich Wöhler showed [by synthesising urea in the laboratory] that the stuff of life is not a magical, pulsating gel, but ordinary compounds following the laws of chemistry.
     From: Steven Pinker (The Blank Slate [2002], Ch.3)
     A reaction: Wöhler synthesised urea in the laboratory.
27. Natural Reality / G. Biology / 3. Evolution
All the evidence says evolution is cruel and wasteful, not intelligent [Pinker]
     Full Idea: The overwhelming evidence is that the process of evolution, far from being intelligent and purposeful, is wasteful and cruel.
     From: Steven Pinker (The Blank Slate [2002], Ch.7)
     A reaction: This is why opponents should reject evolution totally, rather than compromise with it. Stick to a 6000-year-old world, fossils sent to test our faith, and species created in a flash (with no pain or waste).
Intelligent Design says that every unexplained phenomenon must be design, by default [Pinker]
     Full Idea: The originator of 'intelligent design' (the biochemist Michael Behe) takes every phenomenon whose evolutionary history has not yet been figured out, and chalks it up to design by default.
     From: Steven Pinker (The Blank Slate [2002], Ch.7)
     A reaction: This seems to summarise the strategy very nicely. The theory essentially exploits the 'wow!' factor. The bigger the wow! the more likely it is that it was created by God. But research has been eroding our wows steadily for four hundred years.

The supreme general but empty concepts must be compatible, and hence we get 'God' [Nietzsche]
     Full Idea: The supreme concepts of philosophers cannot be incommensurate with one another, be incompatible with one another... Thus they acquired their stupendous concept 'God'.... The last, thinnest, emptiest is placed as the first, as cause in itself.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.4)

By denying God we deny human accountability, and thus we redeem the world [Nietzsche]
     Full Idea: We deny God; in denying God we deny accountability; only by doing that do we redeem the world.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 5.8)
29. Religion / B. Monotheistic Religion / 4. Christianity / a. Christianity
How could the Church intelligently fight against passion if it preferred poorness of spirit to intelligence? [Nietzsche]
     Full Idea: The primitive church fought against the 'intelligent' in favour of the 'poor in spirit': how could one expect from it an intelligent war against passion?
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.1)
Christians believe that only God can know what is good for man [Nietzsche]
     Full Idea: Christianity presupposes that man does not know, cannot know what is good for him and what evil: he believes in God, who alone knows.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.05)

People who disparage actual life avenge themselves by imagining a better one [Nietzsche]
     Full Idea: If there is a strong instinct for slandering, disparaging and accusing life within us, then we revenge ourselves on life by means of the phantasmagoria of 'another', a 'better' life.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.6)
