1. Philosophy / B. History of Ideas / 5. Later European Thought
The Scientific Revolution was the discovery of our own ignorance [Harari]
     Full Idea: The great discovery of the Scientific Revolution was that humans do not know the answers to their most important question.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 14 'Ignoramus')
     A reaction: I think of that revolution as raising the bar in epistemology, but this idea gives a motivation for doing so. Why the discovery then, and not before?
For millenia people didn't know how to convert one type of energy into another [Harari]
     Full Idea: For millenia people didn't know how to convert one type of energy into another, …and the only machine capable of performing energy conversion was the body.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 17 'Intro')
     A reaction: Hence the huge and revolutionary importance of the steam engine and the electricity generator.
1. Philosophy / F. Analytic Philosophy / 7. Limitations of Analysis
If you know what it is, investigation is pointless. If you don't, investigation is impossible [Armstrong]
     Full Idea: Paradox of Analysis:if we ask what sort of thing an X is, then either we know what an X is or we do not. If we know then there is no need to ask the question. If we do not know then there is no way to begin the investigation. It's pointless or impossible
     From: David M. Armstrong (What is a Law of Nature? [1983], 01.2)
     A reaction: [G.E. Moore is the source of this, somewhere] Plato worried that to get to know something you must already know it. Solving this requires the concept of a 'benign' circularity.
7. Existence / D. Theories of Reality / 8. Facts / b. Types of fact
Negative facts are supervenient on positive facts, suggesting they are positive facts [Armstrong]
     Full Idea: Negative facts appear to be supervenient upon the positive facts, which suggests that they are nothing more than the positive facts.
     From: David M. Armstrong (What is a Law of Nature? [1983], 10.3)
8. Modes of Existence / A. Relations / 4. Formal Relations / a. Types of relation
Nothing is genuinely related to itself [Armstrong]
     Full Idea: I believe that nothing is genuinely related to itself.
     From: David M. Armstrong (What is a Law of Nature? [1983], 10.7)
8. Modes of Existence / B. Properties / 1. Nature of Properties
All instances of some property are strictly identical [Armstrong]
     Full Idea: A property ...is something which is strictly identical, strictly the same, in all its different instances.
     From: David M. Armstrong (What is a Law of Nature? [1983], 06.2)
     A reaction: Some is gravitation one property, or an infinity of properties, for each of its values? What is the same between objects of different mass. I sort of believe in all the masses, but I'm not sure what 'mass' is. Abstraction, say I.
8. Modes of Existence / B. Properties / 6. Categorical Properties
Armstrong holds that all basic properties are categorical [Armstrong, by Ellis]
     Full Idea: I am against Armstrong's strong categoricalism, that is, the thesis that all basic properties are categorical.
     From: report of David M. Armstrong (What is a Law of Nature? [1983]) by Brian Ellis - The Metaphysics of Scientific Realism 3
     A reaction: I certainly agree with this, as I cannot see where the power would come from to get the whole thing off the ground. Armstrong depends on universals to necessitate what happens, which I find very peculiar.
8. Modes of Existence / C. Powers and Dispositions / 7. Against Powers
Actualism means that ontology cannot contain what is merely physically possible [Armstrong]
     Full Idea: Actualism ...debars us from admitting into our ontology the merely possible, not only the merely logically possible, but also the merely physically possible.
     From: David M. Armstrong (What is a Law of Nature? [1983], 01.3)
     A reaction: This is the big metaphysical question for fans (like myself) of 'powers' in nature. Armstrong declares himself an Actualist. I take it as obvious that the actual world contains powers, but how are we to characterise them?
Dispositions exist, but their truth-makers are actual or categorical properties [Armstrong]
     Full Idea: It is not denied that statements attributing dispositions and/or powers to objects are often true. But the truth-makers or ontological ground for such statements must always be found in the actual, or categorical, properties of the objects involved.
     From: David M. Armstrong (What is a Law of Nature? [1983], 01.3)
     A reaction: This is the big debate in the topic of powers. I love powers, but you always think there must be 'something' which has the power. Could reality entirely consist of powers? See Fetzer.
If everything is powers there is a vicious regress, as powers are defined by more powers [Armstrong]
     Full Idea: I believe reducing all universals to powers is involved in vicious regress. The power is what it is by the sort of actualisations it gives rise to in suitable sorts of circumstances. But they themselves can be nothing but powers...
     From: David M. Armstrong (What is a Law of Nature? [1983], 08.3)
     A reaction: [compressed wording] I don't see this problem. Anything postulated as fundamental is going to be baffling. Why are categorical properties superior to powers? Postulate basic powers (or basic empowered stuff), then build up.
8. Modes of Existence / D. Universals / 1. Universals
Universals are just the repeatable features of a world [Armstrong]
     Full Idea: Universals can be brought into the spatio-temporal world, becoming simply the repeatable features of that world.
     From: David M. Armstrong (What is a Law of Nature? [1983], 06.2)
     A reaction: I wish Armstrong wouldn't use the word 'universal', which has so much historical baggage. The world obviously has repeatable features, but does that mean that our ontology must include things called 'features'? Hm.
8. Modes of Existence / D. Universals / 2. Need for Universals
Realist regularity theories of laws need universals, to pick out the same phenomena [Armstrong]
     Full Idea: A Realistic version of a Regularity theory of laws will have to postulate universals. How else will it be possible to say that the different instances of a certain uniformity are all instances of objectively the same phenomenon?
     From: David M. Armstrong (What is a Law of Nature? [1983], 02.4)
     A reaction: I disagree. We may (or may not) need properties, but they can be have a range. We just need stable language. We use one word 'red', even when the shade of redness varies. Non-realists presumably refer to sense-data.
8. Modes of Existence / D. Universals / 3. Instantiated Universals
Past, present and future must be equally real if universals are instantiated [Armstrong]
     Full Idea: Past, present and future I take to be all and equally real. A universal need not be instantiated now.
     From: David M. Armstrong (What is a Law of Nature? [1983], 06.2)
     A reaction: This is the price you must pay for saying that you only believe in universals which are instantiated.
Universals are abstractions from their particular instances [Armstrong, by Lewis]
     Full Idea: Armstrong takes universals generally, and structural universals along with the rest, to be abstractions from their particular instances.
     From: report of David M. Armstrong (What is a Law of Nature? [1983], p.83-4) by David Lewis - Against Structural Universals 'The pictorial'
     A reaction: To me, 'abstracted' implies a process of human psychology, a way of thinking about the instances. I don't see how there can be an 'abstracted' relation which is a part of the external world. That makes his laws of nature human creations.
Universals are abstractions from states of affairs [Armstrong]
     Full Idea: Universals are abstractions from states of affairs.
     From: David M. Armstrong (What is a Law of Nature? [1983], 7)
     A reaction: I'm getting confused about Armstrong's commitments. He bases his whole theory on the existence of universals (repeatable features), but now says those are 'abstracted' from something else. Abstracted by us?
9. Objects / A. Existence of Objects / 5. Individuation / b. Individuation by properties
It is likely that particulars can be individuated by unique conjunctions of properties [Armstrong]
     Full Idea: For each particular it is likely that there exists at least one individuating conjunction of properties, that is, a conjunction of properties such that the particular instantiates this conjunction and nothing else does.
     From: David M. Armstrong (What is a Law of Nature? [1983], 02.3)
     A reaction: Armstrong commits to a famous Leibniz view, but I don't see his grounds for it. There is nothing incoherent about nature churning out perfect replicas of things, such as quarks and electrons. Would we care if two pens were perfectly identical?
9. Objects / F. Identity among Objects / 5. Self-Identity
The identity of a thing with itself can be ruled out as a pseudo-property [Armstrong]
     Full Idea: There is reason to rule out as pseudo-properties such things as the identity of a thing with itself.
     From: David M. Armstrong (What is a Law of Nature? [1983], 06.2)
     A reaction: Good on you, David.
10. Modality / B. Possibility / 5. Contingency
The necessary/contingent distinction may need to recognise possibilities as real [Armstrong]
     Full Idea: It may be that the necessary/contingent distinction is tied to a metaphysics which recognises possibility as a real something wider than actuality.
     From: David M. Armstrong (What is a Law of Nature? [1983], 11.2)
     A reaction: Armstrong responds by trying to give an account of possibility in terms of 'combinations' from actuality. I think powers offer a much better strategy.
14. Science / C. Induction / 3. Limits of Induction
Induction aims at 'all Fs', but abduction aims at hidden or theoretical entities [Armstrong]
     Full Idea: Many philosophers of science have distinguished between 'simple induction' - the argument from observed Fs to all Fs - and the argument to hidden or theoretical entities (Peirce's 'abduction').
     From: David M. Armstrong (What is a Law of Nature? [1983], 06.7)
     A reaction: 'Abduction' is (roughly) the same is inference to the best explanation, of which I am a great fan.
14. Science / C. Induction / 5. Paradoxes of Induction / a. Grue problem
Science suggests that the predicate 'grue' is not a genuine single universal [Armstrong]
     Full Idea: It is plausible to say, on the basis of total science, that 'grue' is a predicate to which no genuine, that is, unitary, universal corresponds.
     From: David M. Armstrong (What is a Law of Nature? [1983], 06.7)
Unlike 'green', the 'grue' predicate involves a time and a change [Armstrong]
     Full Idea: The predicate 'grue' involves essential reference to a particular time, which 'green' does not. Also on the 'grue' hypothesis a change occurs in emeralds in a way that change does not occur on the 'green' hypothesis.
     From: David M. Armstrong (What is a Law of Nature? [1983], 04.5)
     A reaction: I'm inclined to think that comparing 'grue' with 'green' is a category mistake. 'Grue' is a behaviour. Armstrong says this is no objection, because Goodman's argument is purely formal.
14. Science / C. Induction / 5. Paradoxes of Induction / b. Raven paradox
The raven paradox has three disjuncts, confirmed by confirming any one of them [Armstrong]
     Full Idea: We could rewrite the generalisation as For all x, ((x is a raven and x is black) v (x is not a raven and x is black) v (x is not a raven and x is not black)). Instances of any one of the three disjuncts will do as confirmation.
     From: David M. Armstrong (What is a Law of Nature? [1983], 04.3)
     A reaction: A nice clarification.
14. Science / D. Explanation / 2. Types of Explanation / a. Types of explanation
A good reason for something (the smoke) is not an explanation of it (the fire) [Armstrong]
     Full Idea: A good reason for P is not necessarily an explanation of P. The presence of smoke is a good reason for thinking that fire is present. But it is not an explanation of the presence of fire.
     From: David M. Armstrong (What is a Law of Nature? [1983], 04.2)
     A reaction: This may be an equivocation on 'the reason for'. Smoke is a reason for thinking there is a fire, but no one would propose it as a reason for the fire. If the reason for the fire was arson, that would seem to explain it as well.
14. Science / D. Explanation / 2. Types of Explanation / e. Lawlike explanations
To explain observations by a regular law is to explain the observations by the observations [Armstrong]
     Full Idea: Given the Regularity theory, the explanatory element seems to vanish. For to say that all the observed Fs are Gs because all the Fs are Gs involves explaining the observations in terms of themselves.
     From: David M. Armstrong (What is a Law of Nature? [1983], 06.7)
     A reaction: This point cries out, it is so obvious (once spotted). Tigers are ferocious because all tigers are ferocious (see?).
14. Science / D. Explanation / 3. Best Explanation / a. Best explanation
Best explanations explain the most by means of the least [Armstrong]
     Full Idea: The best explanation explains the most by means of the least. Explanation unifies.
     From: David M. Armstrong (What is a Law of Nature? [1983], 05.4)
     A reaction: To get unification, you need to cite the diversity of what is explained, and not the mere quantity. The force of gravity unifies because it applies to such a diversity of things.
18. Thought / E. Abstraction / 1. Abstract Thought
Each subject has an appropriate level of abstraction [Armstrong]
     Full Idea: To every subject, its appropriate level of abstraction.
     From: David M. Armstrong (What is a Law of Nature? [1983], 01.2)
     A reaction: Mathematics rises through many levels of abstraction. Economics can be very concrete or very abstract. It think it is clearer to talk of being 'general', rather than 'abstract'.
23. Ethics / C. Virtue Theory / 4. External Goods / c. Wealth
Money does produce happiness, but only up to a point [Harari]
     Full Idea: An interesting conclusion (from questionnaires) is that money does indeed bring happiness. But only up to a point, and beyond that point it has little significance.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 19 'Counting')
     A reaction: The question is whether that flattening-off point is relative to those around us, or absolute, according to the needs of living. Though these two may not be separate.
24. Political Theory / A. Basis of a State / 1. A People / c. A unified people
If a group is bound by gossip, the natural size is 150 people [Harari]
     Full Idea: Sociological research has shown that the maximum 'natural' size of a group bound by gossip is about 150 individuals.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 02 'Legend')
     A reaction: On the other hand, most of us can learn the names of a group of about 450. Maybe the 'known' group and the 'gossip' group are equally significant. Not much use for a modern state, but of interest to communitarians.
24. Political Theory / A. Basis of a State / 2. Population / a. Human population
Since 1500 human population has increased fourteenfold, and consumption far more [Harari]
     Full Idea: In the year 1500 there were about 500 million Homo sapiens in the world. Today there are 7 billion. …Human population has increased fourteenfold, our production 240-fold, and energy consumption 115-fold.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 14 'Discovery')
     A reaction: We really need to grasp how extraordinary this is.
People 300m tons; domesticated animals 700m tons; larger wild animals 100m tons [Harari]
     Full Idea: The combined mass of homo sapiens is about 300 million tons; the mass of all domesticated farmyard animals is about 700 million tons; the mass of the surviving larger wild animals (from porcupines up) is less than 100 million tons.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 18 'Permanent')
     A reaction: These really are figures that deserve much wider currency. Every school entrance hall needs a board with a few of the basic dramatic statistics about human life on Earth.
24. Political Theory / B. Nature of a State / 1. Purpose of a State
The Nazi aim was to encourage progressive evolution, and avoid degeneration [Harari]
     Full Idea: The main ambition of the Nazis was to protect humankind from degeneration and encourage its progressive evolution. …Given the state of scientific knowledge in 1933, Nazi beliefs were hardly outside the pale.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 12 'Worship')
     A reaction: It still sounds a fairly worthy ambition, close to the heart of educationalists everywhere. The problems start with the definition of 'degeneration' and 'progress'.
24. Political Theory / B. Nature of a State / 5. Culture
We stabilise societies with dogmas, either of dubious science, or of non-scientific values [Harari]
     Full Idea: Modern attempts to stabilise the sociopolitical order either declare a scientific theory (such as racial theories for Nazis, or economic ones for Communists) to be an absolute truths, or declare non-scientific dogmas (such as liberal values)
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 14 'Ignoramus')
     A reaction: [compressed]
24. Political Theory / D. Ideologies / 6. Liberalism / b. Liberal individualism
The state fostered individualism, to break the power of family and community [Harari]
     Full Idea: States and markets use their growing power to weaken the bonds of family and community. They made an offer that couldn't be refused - 'become individuals' (over marriage, jobs and residence). The 'romantic individual' is not a rebel against the state.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 18 'Collapse')
     A reaction: [compressed] See the film 'Breaking the Waves'. An interesting slant on the Romantic movement. See Wordsworth's 'Michael'. Capitalism needs shoppers with their own money, and a mobile workforce.
24. Political Theory / D. Ideologies / 7. Communitarianism / a. Communitarianism
In 1750 losing your family and community meant death [Harari]
     Full Idea: A person who lost her family and community around 1750 was as good as dead.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 18 'Collapse')
     A reaction: This is a very good advert for liberal individualism, and marks the downside of 'too much community'.
24. Political Theory / D. Ideologies / 11. Capitalism
The sacred command of capitalism is that profits must be used to increase production [Harari]
     Full Idea: In the new capitalist creed, the first and most sacred commandment is: The profits of production must be reinvested in increasing production.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 16 'Growing')
     A reaction: In this sense, capitalism is less greedy than its predecessors. 17th century aristocratic monopolists simply spent the profits of their activities. See the gorgeous clothes then (and pyramids and palaces), and the quiet suits of capitalists.
The main rule of capitalism is that all other goods depend on economic growth [Harari]
     Full Idea: The principle tenet of capitalism is that economic growth is the supreme good, or at least a proxy for it, because justice, freedom, and even happiness all depend on economic growth.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 16 'Growing')
     A reaction: In this respect, the main opponent of captitalism is green politics, rather than marxism.
The progress of capitalism depends entirely on the new discoveries and gadgets of science [Harari]
     Full Idea: The history of capitalism is unintelligible without taking science into account. …The human economy has managed to keep on going only thanks to the fact that scientists come up with a new discovery or gadget every few years.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 16 'Growing')
     A reaction: For example, the desperate but unconvincing attempts to persuade us of the novelty of new models of car. Built-in obsolescence is needed once a design becomes static.
In capitalism the rich invest, and the rest of us go shopping [Harari]
     Full Idea: The supreme commandment of the rich is 'invest!', and the supreme commandment of the rest of us is 'buy!'
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 17 'Age')
     A reaction: Hence not only do the rich get much richer, while most of us remain roughly where we were, but there is a huge gulf between the investors and the non-investors. Encouraging small investors is a step forward.
25. Social Practice / A. Freedoms / 4. Free market
No market is free of political bias, and markets need protection of their freedoms [Harari]
     Full Idea: There is no such thing as a market free of all political bias, …and markets by themselves offer no protection against fraud, theft and violence.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 16 'Cult')
     A reaction: Is this in theory, or in practice? In Sicily the free market has been a tool of the mafia.
25. Social Practice / A. Freedoms / 5. Freedom of lifestyle
Freedom may work against us, as individuals can choose to leave, and make fewer commitments [Harari]
     Full Idea: The freedom we value so highly may work against us. We can choose our spouses, friends and neighbours, but they can choose to leave us. With the individual wielding unprecedented power to decide her own path, we find it ever harder to make commitments.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 19 'Counting')
     A reaction: This is the worry of the communitarian. I take freedom to be a great social virtue - but an overrated one.
25. Social Practice / E. Policies / 1. War / e. Peace
Real peace is the implausibility of war (and not just its absence) [Harari]
     Full Idea: Real peace is not the mere absence of war. Real peace is the implausibility of war.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 18 'Pax')
     A reaction: I have a nasty feeling that war only becomes implausible because it hasn't happened for a long time. War looked implausible for Britain in 1890. War certainly now looks implausible in western Europe.
25. Social Practice / E. Policies / 4. Taxation
Financing is increasingly through credit rather than taxes; people prefer investing to taxation [Harari]
     Full Idea: The European conquest of the world was increasingly financed through credit rather than taxes. …Nobody wants to pay taxes, but everyone is happy to invest.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 16 'Columbus')
     A reaction: This is presumably the mechanism that drives the unstoppable increase of the gulf between the rich and the poor in modern times. With investment, the rich get richer.
25. Social Practice / E. Policies / 5. Education / d. Study of history
The more you know about history, the harder it becomes to explain [Harari]
     Full Idea: A distinguishing mark of history is that the better you know a historical period, the harder it becomes to explain why things happened one way and not another.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 13 'Hindsight')
     A reaction: Presumaby that means it resembles statistics. Each individual reading is perplexing, but some patterns emerge on the large scale.
History teaches us that the present was not inevitable, and shows us the possibilities [Harari]
     Full Idea: We study history not to know the future but to widen our horizons, to understand that our present situation is neither natural nor inevitable, and the we consequently have many more possibilities before us than we can imagine.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 13 'Hindsight')
     A reaction: On the whole winners forget history, and losers are branded through and through with it. If you don't know history, you can never understand the latter group.
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / e. The One
We can't deduce the phenomena from the One [Armstrong]
     Full Idea: No serious and principled deduction of the phenomena from the One has ever been given, or looks likely to be given.
     From: David M. Armstrong (What is a Law of Nature? [1983], 11)
     A reaction: This seems to pick out the best reason why hardly anybody (apart from Jonathan Schaffer) takes the One seriously.
26. Natural Theory / C. Causation / 2. Types of cause
Absences might be effects, but surely not causes? [Armstrong]
     Full Idea: Lacks and absences could perhaps by thought of as effects, but we ought to be deeply reluctant to think of them as causes.
     From: David M. Armstrong (What is a Law of Nature? [1983], 10.4)
     A reaction: Odd. So we allow that they exist (as effects), but then deny that they have any causal powers?
26. Natural Theory / D. Laws of Nature / 1. Laws of Nature
A universe couldn't consist of mere laws [Armstrong]
     Full Idea: A universe could hardly consist of laws and nothing else.
     From: David M. Armstrong (What is a Law of Nature? [1983], 06.4)
     A reaction: Hm. Discuss. How does a universe come into existence, if there are no laws to guide its creation?
Science depends on laws of nature to study unobserved times and spaces [Armstrong]
     Full Idea: The scientist trying to establish the geography and history of the unobserved portion of the universe must depend upon what he takes to be the laws of the universe.
     From: David M. Armstrong (What is a Law of Nature? [1983], 01.1)
     A reaction: This does seem to be the prime reason why we wish to invoke 'laws', but we could just as well say that we have to rely on induction. Spot patterns, then expect more of the same. Spot necessities? Mathematics is very valuable here, of course.
26. Natural Theory / D. Laws of Nature / 2. Types of Laws
Oaken conditional laws, Iron universal laws, and Steel necessary laws [Armstrong, by PG]
     Full Idea: Three degress of law: 1) 'Oaken laws' where all Fs that aren't Hs are Gs; 2) 'Iron' laws where all Fs are Gs; and 3) 'Steel' laws where all Fs must be Gs.
     From: report of David M. Armstrong (What is a Law of Nature? [1983], 10.4) by PG - Db (ideas)
     A reaction: [My summary of Armstrong's distinction] One response is to say that all laws are actually Oaken - see Mumfor and Mumford/Lill Anjum. It's all ceteris paribus.
26. Natural Theory / D. Laws of Nature / 3. Laws and Generalities
Newton's First Law refers to bodies not acted upon by a force, but there may be no such body [Armstrong]
     Full Idea: Newton's First Law of Motion tells us what happens to a body which is not acted upon by a force. Yet it may be that the antecedent of the law is never instantiated. It may be that every body that there is, is acted upon by some force.
     From: David M. Armstrong (What is a Law of Nature? [1983], 02.7)
26. Natural Theory / D. Laws of Nature / 4. Regularities / a. Regularity theory
Regularities are lawful if a second-order universal unites two first-order universals [Armstrong, by Lewis]
     Full Idea: Armstrong's theory holds that what makes certain regularities lawful are second-order states of affairs N(F,G) in which the two ordinary first-order universals F and G are related by a certain dyadic second-order universal N.
     From: report of David M. Armstrong (What is a Law of Nature? [1983]) by David Lewis - New work for a theory of universals 'Laws and C'
     A reaction: [see Lewis's footnote] I take the view (from Shoemaker and Ellis) that laws of nature are just plain regularities which arise from the hierarchy of natural kinds. We don't need a commitment to 'universals'.
A naive regularity view says if it never occurs then it is impossible [Armstrong]
     Full Idea: It is a Humean uniformity that no race of ravens is white-feathered. Hence, if the Naive Regularity analysis of law is correct, it is a law that no race of ravens is white-feathered, that is, such a race is physically impossible. A most unwelcome result.
     From: David M. Armstrong (What is a Law of Nature? [1983], 02.6)
     A reaction: Chapters 2-4 of Armstrong are a storming attack on the regularity view of laws of nature, and this idea is particularly nice. Laws must refer to what could happen, not what happens to happen.
26. Natural Theory / D. Laws of Nature / 5. Laws from Universals
The laws of nature link properties with properties [Armstrong]
     Full Idea: There is an utterly natural idea that the laws of nature link properties with properties.
     From: David M. Armstrong (What is a Law of Nature? [1983], 06.3)
     A reaction: Put it this way: given that properties are expressions of invariant powers, the interaction of two properties will (ceteris paribus) be invariant, and laws are just invariances in natural behaviour.
Rather than take necessitation between universals as primitive, just make laws primitive [Maudlin on Armstrong]
     Full Idea: My own view is simple: the laws of nature ought to be accepted as ontologically primitive. …They are preferable in point of familiarity to such necessitation relations between universals.
     From: comment on David M. Armstrong (What is a Law of Nature? [1983]) by Tim Maudlin - The Metaphysics within Physics 1.4
     A reaction: I think you make natures of things primitive, and reduce laws to regularities and universals to resemblances. Job done. Natures are even more 'familiar' as primitives than laws are.
Armstrong has an unclear notion of contingent necessitation, which can't necessitate anything [Bird on Armstrong]
     Full Idea: The two criticisms levelled against Armstrong are that it is unclear what his relation of contingent necessitation is, and that it is unclear how it is able to necessitate anything.
     From: comment on David M. Armstrong (What is a Law of Nature? [1983]) by Alexander Bird - Nature's Metaphysics 3.1.2
     A reaction: I suppose someone has to explore the middle ground between the mere contingencies of Humean regularities and the strong necessities of scientific essentialism. The area doesn't, however, look promising.
28. God / C. Attitudes to God / 1. Monotheism
In order to explain both order and evil, a single evil creator is best, but no one favours that [Harari]
     Full Idea: Monotheism explains order but not evil, and dualist religion explains evil but not order. One logical solution is a single omnipotent God who created the universe, and is evil - but nobody in history has had much stomach for that belief.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 12 'Battle')
     A reaction: Eh? Is there not also good, which also needs explaining? And there is some chaos to be explained too. Hume offers the best explanations. An inexperienced god, a team of squabbling gods, a god with shifting moods…. Study the facts first.
29. Religion / A. Polytheistic Religion / 1. Animism
Animism is belief that every part of nature is aware and feeling, and can communicate [Harari]
     Full Idea: Animism is the belief that almost every place, every animal, every plant and every natural phenomenon has awareness and feelings, and can communicated direct with humans.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 03 'Talking')
     A reaction: So does this count as a 'supernatural' belief system? It seems not, if the awareness is integral to the natural feature, and dies with it. Panpsychism is not supernatural either. A problem for anyone trying to define Naturalism.
29. Religion / A. Polytheistic Religion / 2. Greek Polytheism
Most polytheist recognise one supreme power or law, behind the various gods [Harari]
     Full Idea: Polytheism does not necessarily dispute the existence of a single power or law governing the entire universe. Most poytheist and even animist religions recognised such a supreme power that stands behind all the different gods, demons and holy rocks.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 12 'Benefits')
     A reaction: Presumably this one supreme power was always taken to be too remote for communication or worship. Are the other gods seen as slaves, or friends, or ambassadors of the Supreme One?
Polytheism is open-minded, and rarely persecutes opponents [Harari]
     Full Idea: Polytheism is inherently open-minded, and rarely persecutes 'heretics' and 'infidels'.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 12 'Benefits')
     A reaction: The Old Testament tells of the Jews turning on local pagans, and India was presumably tolerant Hindus encountering less tolerant Muslims. Then there's Christians in Africa. Dreadful bunch, the monotheists. Romans killed very few Christians.
Mythologies are usual contracts with the gods, exchanging devotion for control of nature [Harari]
     Full Idea: Much of ancient mythology is a legal contract in which humans promise everlasting devotion to the gods in exchange for mastery over plants and animals.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 12 'Silencing')
     A reaction: [He cites the first book of Genesis] So how readily do you swith allegiance, if someone else's gods are more successful? Why be loyal a loser. It should be like shopping - but I bet it wasn't.
29. Religion / A. Polytheistic Religion / 4. Dualist Religion
Dualist religions see everything as a battleground of good and evil forces [Harari]
     Full Idea: Polytheism gave birth to monotheism, and to dualistic religions. Dualism explains that the entire universe is a battleground between good and evil forces, and everything that happens is part of that struggle.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 12 'Battle')
     A reaction: Presumably we are supposed to support the good guys, so the gods are not equals. God v Satan seems the right model, but Satan has to be beyond God's control, or else the problem of evil has to be solved. Empedocles held something like this.
Dualist religions say the cosmos is a battleground, so can’t explain its order [Harari]
     Full Idea: Dualist religions solve the problem of evil, but are unnerved by the Problem of Order. …If Good and Evil battle for control of the world, who enforces the laws governing this cosmic war?
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 12 'Battle')
     A reaction: You might explain it if one side was persistently winning, which is roughly God v Satan.
Manichaeans and Gnostics: good made spirit, evil made flesh [Harari]
     Full Idea: Manichaeans and Gnostics argued that the good god created the spirit and the soul, whereas matter and bodes are the creation of the evil god.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 12 'Battle')
     A reaction: Hm. What motivated the evil god to do that? The evil god's achievement looks a lot more impressive.
29. Religion / B. Monotheistic Religion / 1. Monotheistic Religion
Monotheism appeared in Egypt in 1350 BCE, when the god Aten was declared supreme [Harari]
     Full Idea: The first monotheist religion known to us appeared in Egypt c.1350 BCE, when Pharaoh Akenaten declared that one of minor deities of the Egyptian pantheon, the god Aten, was in fact the supreme power ruling the universe.
     From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 12 'God')
     A reaction: Zeus seems to have started like a tribal chief, and eventually turned into something like God.
29. Religion / B. Monotheistic Religion / 4. Christianity / d. Heresy
Philosophers are the forefathers of heretics [Tertullian]
     Full Idea: Philosophers are the forefathers of heretics.
     From: Tertullian (works [c.200]), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 20.2
29. Religion / D. Religious Issues / 1. Religious Commitment / e. Fideism
I believe because it is absurd [Tertullian]
     Full Idea: I believe because it is absurd ('Credo quia absurdum est').
     From: Tertullian (works [c.200]), quoted by Robert Fogelin - Walking the Tightrope of Reason n4.2
     A reaction: This seems to be a rather desperate remark, in response to what must have been rather good hostile arguments. No one would abandon the support of reason if it was easy to acquire. You can't deny its engaging romantic defiance, though.
