1. Philosophy / A. Wisdom / 3. Wisdom Deflated
Because of Darwin, wisdom as a definite attainable state has faded [Watson]
     Full Idea: As well as killing the need for God, Darwin's legacy transformed the idea of wisdom, as some definite attainable state, however far off.
     From: Peter Watson (Ideas [2005], Ch.31)
     A reaction: Where does this leave philosophy, if it is still (as I like to think) the love of wisdom? The best we can hope for is wisdom as a special sort of journey - touring, rather than arriving.
1. Philosophy / B. History of Ideas / 1. History of Ideas
The three key ideas are the soul, Europe, and the experiment [Watson]
     Full Idea: The three key ideas that I have settled on in the history of ideas are: the soul, Europe, and the experiment.
     From: Peter Watson (Ideas [2005], Intro)
     A reaction: The soul is a nice choice (rather than God). 'Europe' seems rather vast and indeterminate to count as a key idea.
The big idea: imitation, the soul, experiments, God, heliocentric universe, evolution? [Watson]
     Full Idea: Candidates for the most important idea in human history are: mimetic thinking (imitation), the soul, the experiment, the One True God, the heliocentric universe, and evolution.
     From: Peter Watson (Ideas [2005], Ch.03)
     A reaction: From this list I would choose the heliocentric universe, because it so dramatically downgraded the importance of our species (effectively we went from everything to nothing). We still haven't recovered from the shock.
2. Reason / A. Nature of Reason / 1. On Reason
Traditionally, rational beliefs are those which are justified by reasons [Psillos]
     Full Idea: The traditional conception of Reason is that all beliefs should be justified (that is, backed up by reasons) in order to be rational.
     From: Stathis Psillos (Causation and Explanation [2002], §1.6)
     A reaction: I think it is the duty of all philosophers to either defend this traditional view, or quit philosophy for some other activity. Rorty suggests hermeneutics. In a democracy, rulers should be continually required to give reasons for their decisions.
2. Reason / E. Argument / 3. Analogy
Babylonian thinking used analogy, rather than deduction or induction [Watson]
     Full Idea: In Babylon thought seems to have worked mainly by analogy, rather than by the deductive or inductive processes we use in the modern world.
     From: Peter Watson (Ideas [2005], Ch.04)
     A reaction: Analogy seems to be closely related to induction, if it is comparing instances of something. Given their developments in maths and astronomy, they can't have been complete strangers to the 'modern' way of thought.
5. Theory of Logic / K. Features of Logics / 10. Monotonicity
Valid deduction is monotonic - that is, it remains valid if further premises are added [Psillos]
     Full Idea: Valid deductive arguments have the property of monotonicity; if the conclusion Q follows from the premises P, then it will also follow if further premises P* are added to P.
     From: Stathis Psillos (Causation and Explanation [2002], §9.2.1)
     A reaction: For perversity's sake we could add a new premise which contradicted one of the original ones ('Socrates is a god'). Or one premise could be 'I believe..', and the new one could show that the belief was false. Induction is non-monotonic.
6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / c. Counting procedure
Mesopotamian numbers applied to specific things, and then became abstract [Watson]
     Full Idea: To begin with, in Mesopotamia, counting systems applied to specific commodities (so the symbol for 'three sheep' applied only to sheep, and 'three cows' applied only to cows), but later words for abstract qualities emerged.
     From: Peter Watson (Ideas [2005], Ch.04)
     A reaction: It seems from this that we actually have a record of the discovery of true numbers. Delightful. I think the best way to describe what happened is that they began to spot patterns.
7. Existence / A. Nature of Existence / 6. Criterion for Existence
The 'epistemic fallacy' is inferring what does exist from what can be known to exist [Psillos]
     Full Idea: The move from what can (or cannot) be known to exist to what does (or does not) exist has been dubbed the 'epistemic fallacy'.
     From: Stathis Psillos (Causation and Explanation [2002], §1.6)
     A reaction: This should be a standard concept in all philosophical discussion. It is the commonest, simplest, and most profound blunder made by philosophers, and they do it all the time.
8. Modes of Existence / B. Properties / 5. Natural Properties
Scientific properties are defined by the laws that embody them [Psillos, by Ladyman/Ross]
     Full Idea: For Psillos, properties in mature science are defined by the laws in which they feature.
     From: report of Stathis Psillos (Scientific Realism [1999]) by J Ladyman / D Ross - Every Thing Must Go 3.5
     A reaction: This is a perfect example of the Humean approach getting everything the wrong way round. Laws are not primitives from which we derive our account of nature - they are generalisations built up from the behaviour of prior properties.
8. Modes of Existence / C. Powers and Dispositions / 2. Powers as Basic
Powers are claimed to be basic because fundamental particles lack internal structure [Psillos]
     Full Idea: The argument for fundamental powers is that fundamental particles are simple, without internal structure. Hence they have no parts which can be the bearers of further properties (powers or non-powers) which in turn ground the properties of the particles.
     From: Stathis Psillos (What do powers do when they are not manifested? [2006], p.151), quoted by Anna Marmodoro - Do powers need powers to make them powerful? 'The Problem'
     A reaction: If a power is basic, what has the power? I think the best answer is that at the fundamental level this is a false dichotomy. If you could zoom in, you would say that basic substance is active in a way that everyday stuff doesn't appear to be.
14. Science / A. Basis of Science / 4. Prediction
If we say where Mars was two months ago, we offer an explanation without a prediction [Psillos]
     Full Idea: There can be explanations without predictions, as when we explain a previous position of Mars from its present one, plus a law.
     From: Stathis Psillos (Causation and Explanation [2002], §8.9)
     A reaction: If we don't mind stretching the word, I think we can 'predict' the past, as where I predict the location of an Egyptian tomb from my study of papyruses.
A good barometer will predict a storm, but not explain it [Psillos]
     Full Idea: There can be predictions without explanations, as when a barometer successfully predicts storms, but on its own it does not explain them.
     From: Stathis Psillos (Causation and Explanation [2002], §8.8)
     A reaction: Actually, barometers contribute to explanations. A reasonable predictor might offer no explanation ('if he's out, she's probably out too'), but an infallible predictor is almost certain to involve causation, which helps a lot in explanation.
14. Science / C. Induction / 4. Reason in Induction
Induction (unlike deduction) is non-monotonic - it can be invalidated by new premises [Psillos]
     Full Idea: Unlike deductive arguments, induction is non-monotonic - that is, it can be invalidated by the addition of new premises.
     From: Stathis Psillos (Causation and Explanation [2002], §9.2.1)
     A reaction: This is a fancy way of stating the obvious, which is that induction is not a type of deduction. Hume is sometimes accused of this false assumption. Presumably induction is rational, even if it is not actually logical.
14. Science / D. Explanation / 2. Types of Explanation / a. Types of explanation
Explanation is either showing predictability, or showing necessity, or showing causal relations [Psillos]
     Full Idea: The three types of explanation are 'epistemic' (the event is expectable because of a law), or 'modal' (the event is necessary because of a law), or 'ontic' (it is shown how the event fits into the world's causal structure).
     From: Stathis Psillos (Causation and Explanation [2002], §11.1)
     A reaction: Prediction, necessity or causes. It is hard to think of any other way to explain something. Presumably you would exclude necessities if you didn't believe in them. Hume would go for prediction, on the basis of regularities. Personally, I want it all.
14. Science / D. Explanation / 2. Types of Explanation / e. Lawlike explanations
Just citing a cause does not enable us to understand an event; we also need a relevant law [Psillos]
     Full Idea: Explanation has to do with understanding; just citing a cause would not offer an adequate understanding, unless it was accompanied by the citation of a law that connects the two events.
     From: Stathis Psillos (Causation and Explanation [2002], §8.2)
     A reaction: It is surely undeniable that being told the cause but not the law will increase our understanding. Understanding and explanation come in degrees. Full understanding would require an explanation of the law, and beyond. Any relevant truth helps.
The 'covering law model' says only laws can explain the occurrence of single events [Psillos]
     Full Idea: The 'deductive-nomological' model became known as the 'covering law model': its main thesis is that laws and only laws adequately explain the occurrence of singular events.
     From: Stathis Psillos (Causation and Explanation [2002], §8.2)
     A reaction: But presumably you need other events to derive a law, so you could say that a singular event can only be explained if it isn't singular. A regularity pattern would offer a partial explanation, before any law had been derived.
If laws explain the length of a flagpole's shadow, then the shadow also explains the length of the pole [Psillos]
     Full Idea: If we use geometry and optics to explain the length of shadow cast by a flag-pole, this seems to be reversible, so that the shadow will explain the length of the pole.
     From: Stathis Psillos (Causation and Explanation [2002], §8.5)
     A reaction: A neat example which presumably implies that an explanation must involve temporal statements. The laws of physics are totally reversible in time, and so will not suffice to explain events on their own. Time's arrow becomes an axiom of explanation?
14. Science / D. Explanation / 2. Types of Explanation / g. Causal explanations
There are non-causal explanations, most typically mathematical explanations [Psillos]
     Full Idea: There are non-causal explanations, most typically mathematical explanations.
     From: Stathis Psillos (Causation and Explanation [2002], Intro)
     A reaction: A crucial basic point, which must be drummed into the minds of ruthless Quinean naturalists, who want to explain everything by quarks and electrons
An explanation can just be a 'causal story', without laws, as when I knock over some ink [Psillos]
     Full Idea: Knocking over an ink bottle explains the stain on the carpet, and it is not in doubt because you cannot quote the laws involved; a 'causal story' can give a complete explanation without a law.
     From: Stathis Psillos (Causation and Explanation [2002], §8.6)
     A reaction: But why is he so clumsy, and the bottle so unstable? Was it really (Freudian) an 'accident'? There is no end to complete explanation. But 'I was clumsy this once' and 'I am always clumsy' are equally good explanations.
14. Science / D. Explanation / 4. Explanation Doubts / a. Explanation as pragmatic
Maybe explanation is entirely relative to the interests and presuppositions of the questioner [Psillos]
     Full Idea: Some philosophers focus on the so-called 'pragmatics of explanation' - that an explanation is an answer to a 'why' question, and the relevant answer will depend on the presuppositions or interests of the questioner.
     From: Stathis Psillos (Causation and Explanation [2002], Intro)
     A reaction: This seems to me right. Explanation is an entirely human business, not a feature of nature, and most explanations will track back to the big bang if you have the patience, but they always terminate because of pragmatic considerations. But fobbing off?
An explanation is the removal of the surprise caused by the event [Psillos]
     Full Idea: An explanation amounts to the removal of the initial surprise that accompanied the occurrence of the event.
     From: Stathis Psillos (Causation and Explanation [2002], §8.2)
     A reaction: This is a nice simple point. It makes explanation relative. God requires no explanations, small children require many. The implication is that explanations make events predictable, which means they must either offer inductive generalisations, or laws.
15. Nature of Minds / C. Capacities of Minds / 1. Faculties
There are 23 core brain functions, with known circuit, transmitters, genes and behaviour [Watson]
     Full Idea: In 2014 the National Institutes of Mental Health published a list of 23 core brain functions and their associated neural circuitry, neurotransmitters and genes, and the behaviour and emotions that go with them.
     From: Peter Watson (Convergence [2016], 16 'Physics')
     A reaction: They were interested in the functions behind mental health, but I am interested in the functions behind our belief systems, which might produce a different focus. Sub-functions, perhaps.
15. Nature of Minds / C. Capacities of Minds / 9. Perceiving Causation
It is hard to analyse causation, if it is presupposed in our theory of the functioning of the mind [Psillos]
     Full Idea: There is a problem if causation is the object of our analysis, but is also presupposed (as an empirical principle of human psychology) for the functioning of the mind.
     From: Stathis Psillos (Causation and Explanation [2002], §1.7)
     A reaction: This doesn't sound like a major problem. If it is, it is presumably impossible to analyse the mind, because a mind is presupposed in the process of analysis.
17. Mind and Body / E. Mind as Physical / 1. Physical Mind
Traditional ideas of the mind were weakened in the 1950s by mind-influencing drugs [Watson]
     Full Idea: One development in particular in the 1950s helped to discredit the traditional concept of the mind. This was medical drugs that influenced the workings of the brain.
     From: Peter Watson (Convergence [2016], 16 'Intro')
     A reaction: This explains Ryle's 1949 book, and the Australian physicalists emerging in the late 1950s. Philosophers don't grasp how their subject is responsive to other areas of human knowledge. Of course, opium had always done this.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / e. Human nature
Humans have been hunter-gatherers for 99.5% of their existence [Watson]
     Full Idea: Anthropology shows that the hunter-gathering lifestyle has occupied 99.5 per cent of the time humans have been on earth.
     From: Peter Watson (Convergence [2016], 13 'Emergence')
     A reaction: If you are trying to understand humanity, you ignore this fact at your peril. Even agriculture is only a tiny part of our history, and that only disappeared as a major human activity (in many nations) in the last hundred years.
22. Metaethics / B. Value / 1. Nature of Value / b. Fact and value
Nothing is more usual than to apply to external bodies every internal sensation which they occasion [Psillos]
     Full Idea: Nothing is more usual than to apply to external bodies every internal sensation which they occasion.
     From: Stathis Psillos (Causation and Explanation [2002], §1.8)
     A reaction: This is the core of Hume's is/ought claim - what he calls the mind 'spreading itself'. It is a powerful claim. Personally I think we have become TOO sceptical here, and have the delusion that crucial features of nature are created within our minds.
24. Political Theory / D. Ideologies / 5. Democracy / d. Representative democracy
Modern democracy is actually elective oligarchy [Watson]
     Full Idea: What we regard as democracy in the twenty-first century is actually elective oligarchy.
     From: Peter Watson (Ideas [2005], Ch.06)
     A reaction: Even dictatorships want to be called 'democracies'. The modern system is a bit of a concession to Plato, and he would probably have preferred it to his system, because at least the rulers tend to be more educated than the direct assembly.
26. Natural Theory / A. Speculations on Nature / 1. Nature
Greek philosophers invented the concept of 'nature' as their special subject [Watson]
     Full Idea: Greek philosophers may have invented the concept of 'nature' to underline their superiority over poets and religious leaders.
     From: Peter Watson (Ideas [2005], Ch.06)
     A reaction: Brilliant. They certainly wrote a lot of books entitled 'Peri Physis' (Concerning Nature), and it was the target of their expertise. A highly significant development, along with their rational methods. Presumably Socrates extends nature to include ethics.
26. Natural Theory / C. Causation / 1. Causation
Causes clearly make a difference, are recipes for events, explain effects, and are evidence [Psillos]
     Full Idea: The platitudes of causation are that 1) causes make a difference (counterfactually or probabilistically), 2) causes are recipes for events, 3) causes explain their effects, and 4) causes are evidence for effects.
     From: Stathis Psillos (Causation and Explanation [2002], Intro)
     A reaction: A nice piece of analysis which offers some problems for anyone (like Russell) who wants to analyse causation completely out of our conceptual scheme.
Theories of causation are based either on regularity, or on intrinsic relations of properties [Psillos]
     Full Idea: While Humeans base their theories on the intuition of regularity, their opponents base theirs on the intuition that there is an intrinsic relation between the properties of two particular things involved (like a hammer and a vase).
     From: Stathis Psillos (Causation and Explanation [2002], Intro)
     A reaction: I favour the intrinsic relation of properties view, but this leaves the question of whether we can explain a relation, apart from observing the regularities associated with the properties.
We can't base our account of causation on explanation, because it is the wrong way round [Psillos]
     Full Idea: We cannot distinguish between good and bad explanations of some phenomena, unless we first distinguish between causal and non-causal explanations.
     From: Stathis Psillos (Causation and Explanation [2002], Intro)
     A reaction: This seems right, but it pushes us towards the idea that causation is non-analysable, and must be taken as a metaphysically basic axiom. If naturalistic accounts fail, that may be only alternative.
26. Natural Theory / C. Causation / 2. Types of cause
Three divisions of causal theories: generalist/singularist, intrinsic/extrinsic, reductive/non-reductive [Psillos]
     Full Idea: The three ways to divide theories on causation are: between generalist and singularist, between intrinsic and extrinsic characterisations of the causal relationship, and between reductive and non-reductive approaches.
     From: Stathis Psillos (Causation and Explanation [2002], §4.5)
     A reaction: Okay. I vote for singularist, intrinsic and reductive. I'm guessing that that pushes me towards Salmon and Dowe's theory of the 'transfer of conserved quantities', which is certainly reductive, doesn't need regularities in the events, and seems intrinsic.
26. Natural Theory / C. Causation / 4. Naturalised causation
Science has shown that causal relations are just transfers of energy or momentum [Fair, by Sosa/Tooley]
     Full Idea: Basic causal relations can, as a consequence of our scientific knowledge, be identified with certain physicalistic [sic] relations between objects that can be characterized in terms of transference of either energy or momentum between objects.
     From: report of David Fair (Causation and the Flow of Energy [1979]) by E Sosa / M Tooley - Introduction to 'Causation' §1
     A reaction: Presumably a transfer of momentum is a transfer of energy. If only anyone had the foggiest idea what energy actually is, we'd be doing well. What is energy made of? 'No identity without substance', I say. I like Fair's idea.
Fair shifted his view to talk of counterfactuals about energy flow [Fair, by Schaffer,J]
     Full Idea: Fair, who originated the energy flow view of causation, moved to a view that understands connection in terms of counterfactuals about energy flow.
     From: report of David Fair (Causation and the Flow of Energy [1979]) by Jonathan Schaffer - The Metaphysics of Causation 2.1.2
     A reaction: David Fair was a pupil of David Lewis, the king of the counterfactual view. To me that sounds like a disappointing move, but it is hard to think that a mere flow of energy through space would amount to causation. Cause must work back from an effect.
26. Natural Theory / C. Causation / 7. Eliminating causation
The Uncertainty Principle implies that cause and effect can't be measured [Watson]
     Full Idea: The Uncertainty Principle implied that in the subatomic world cause and effect could never be measured.
     From: Peter Watson (Convergence [2016], 05 'Against')
     A reaction: The fact that it can't be measured does not, presumably, entail that it doesn't exist. Physicists seem to ignore causation, rather than denying it. Can causation be real if it only exists at the macro-level, as an emergent phenomenon?
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
If causation is 'intrinsic' it depends entirely on the properties and relations of the cause and effect [Psillos]
     Full Idea: If causation is taken to be an 'intrinsic' relation, then that c causes e will have to depend entirely on the properties of c and e, and the relations between c and e.
     From: Stathis Psillos (Causation and Explanation [2002], §4.5.2)
     A reaction: This view would move us towards 'essentialism', that the essences of objects produce the events and the laws, rather than external imposed forces and laws.
26. Natural Theory / C. Causation / 9. General Causation / b. Nomological causation
Empiricists tried to reduce causation to explanation, which they reduced to logic-plus-a-law [Psillos]
     Full Idea: The logical empiricists (esp. Hempel) analysed the concept of causation in terms of causal explanation, and analysed the latter as a species of deductive argument, with one premises stating a universal law (the so-called Deductive-Nomological model).
     From: Stathis Psillos (Causation and Explanation [2002], Intro)
     A reaction: This feels wrong, as deduction seems insufficiently naturalistic, and the assumption of a law as premise seems to beg heaps of questions.
26. Natural Theory / C. Causation / 9. General Causation / c. Counterfactual causation
Counterfactual claims about causation imply that it is more than just regular succession [Psillos]
     Full Idea: If counterfactual claims can be made about causation, this suggests that there is more to it than mere regular succession.
     From: Stathis Psillos (Causation and Explanation [2002], §2.2)
     A reaction: Interesting. Even Hume makes counterfactual claims in his first definition of cause, and all claims of causation seem to go beyond the immediate evidence.
26. Natural Theory / D. Laws of Nature / 3. Laws and Generalities
"All gold cubes are smaller than one cubic mile" is a true universal generalisation, but not a law [Psillos]
     Full Idea: The statement "all gold cubes are smaller than one cubic mile" seems to have all the features demanded of a lawlike statement, yet it can hardly be said to express a law. It is a merely true universal generalisation.
     From: Stathis Psillos (Causation and Explanation [2002], §5.3)
     A reaction: Nice example. A trickier case is "all cubes of uranium are smaller than one cubic mile", which sounds like part of a law. It suggests a blurred borderline between the two. How much gold is there in the universe? Is that fact a natural necessity?
26. Natural Theory / D. Laws of Nature / 4. Regularities / a. Regularity theory
Regularity doesn't seem sufficient for causation [Psillos]
     Full Idea: A rather important objection to Humeanism has been that regularity is not sufficient for causation.
     From: Stathis Psillos (Causation and Explanation [2002], Intro)
     A reaction: Obviously a crucial problem, but the Humean view can defend itself by introducing other constant conjunctions. We don't observe events in isolation, but as part of a pattern of regularities.
A Humean view of causation says it is regularities, and causal facts supervene on non-causal facts [Psillos]
     Full Idea: The Humean view depends on the conjunction of two general theses: first, causation is tied to regularity; secondly, causal facts supervene on non-causal facts.
     From: Stathis Psillos (Causation and Explanation [2002], §4.5.4)
     A reaction: If causation is just regularities, this means it is patterns observed by us, which means causation doesn't actually exist. So Hume is wrong. Singular causation is possible, and needs explanation.
The regularity of a cock's crow is used to predict dawn, even though it doesn't cause it [Psillos]
     Full Idea: A regularity can be used to predict a future event irrespective of whether it is deemed causal or not. A farmer can predict that dawn has broken on hearing the cock's crow.
     From: Stathis Psillos (Causation and Explanation [2002], §8.1)
     A reaction: This seems a highly significant criticism of any view that says regularity leads to causation, which is the basis of induction, which leads to counterfactual claims, and thus arrives a the laws of nature.
It is not a law of nature that all the coins in my pocket are euros, though it is a regularity [Psillos]
     Full Idea: It is not a law of nature that all the coins in my pocket are euros, though it is a regularity.
     From: Stathis Psillos (Causation and Explanation [2002], Intro)
     A reaction: Good example, but it doesn't demolish the regularity view. We should come to conscious minds last. There aren't many other unfailing regularities that are not laws.
26. Natural Theory / D. Laws of Nature / 4. Regularities / b. Best system theory
Laws are sets of regularities within a simple and strong coherent system of wider regularities [Psillos]
     Full Idea: In the 'web-of-laws' approach, laws are those regularities that are members of a coherent system of regularities, in particular, a system that can be represented as a deductive axiomatic system, striking a good balance between simplicity and strength.
     From: Stathis Psillos (Causation and Explanation [2002], §5.6)
     A reaction: Psillos attribute this view to Mill, Ramsey and Lewis. It is the obvious candidate for a fully developed Humean empiricist system, where regularities reinforce one another. I think laws are found in mechanisms, not in regularities, which are symptoms.
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / e. Anti scientific essentialism
Dispositional essentialism can't explain its key distinction between essential and non-essential properties [Psillos]
     Full Idea: Many philosophers will find dispositional essentialism unappealing, not least because it seems to fail to explain how (and in virtue of what) there is this supposed fundamental distinction between essential and non-essential properties.
     From: Stathis Psillos (Causation and Explanation [2002])
     A reaction: Maybe there is no precise definition, but any idiot can see that some properties of gold are essential (mass) and others non-essential (attractive to jackdaws). It's a fair question, but is this the strongest objection to essentialism?
26. Natural Theory / D. Laws of Nature / 9. Counterfactual Claims
In some counterfactuals, the counterfactual event happens later than its consequent [Psillos]
     Full Idea: In "had the acrobat jumped, there would have been a safety net" the antecedent of the counterfactual (the jumping) is temporally later than the consequent (the installation of the net).
     From: Stathis Psillos (Causation and Explanation [2002], §3.3)
     A reaction: This blocks anyone (e.g. David Lewis) who tries to define counterfactual claims entirely in terms of a condition followed by a consequence. Nice example.
Counterfactual theories say causes make a difference - if c hadn't occurred, then e wouldn't occur [Psillos]
     Full Idea: The counterfactual theory is a non-Humean relation between singular events; the thought is that causation makes a difference - to say that c causes e is to say that if c hadn't occurred, e wouldn't have occurred either.
     From: Stathis Psillos (Causation and Explanation [2002], §4.5.4)
     A reaction: Helpful. I'm beginning to think that this theory is wrong. It gives an account of how we see causation, and a test for it, but it says nothing about what causation actually is.
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / a. Electrodynamics
The interference of light through two slits confirmed that it is waves [Watson]
     Full Idea: Thomas Young in 1803 confirmed the idea of Huyghens that light is waves, showing how light passing through two slits produces an interference pattern that resembles water waves sluicing through two slits.
     From: Peter Watson (Convergence [2016], 04 'Conception')
     A reaction: The great puzzle emerges when it also turns out to be quantised particles.
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / c. Electrons
Electrons rotate in hyrogen atoms 10^13 times per second [Watson]
     Full Idea: In the hydrogen atom the electron rotates some 10,000 billion times per second.
     From: Peter Watson (Convergence [2016], 18 'Evolutionary')
     A reaction: That's an awful lot. Is it at the speed of light?
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / d. Quantum mechanics
Quantum theory explains why nature is made up of units, such as elements [Watson]
     Full Idea: Planck's quantum idea explained so much, including the observation that the chemical world is made up of discrete units - the elements. Discrete elements implied fundamental units of matter that were themselves discrete (as Dalton had said).
     From: Peter Watson (Convergence [2016], 4 'Intro')
     A reaction: The atomic theory was only finally confirmed by Einstein in 1905. This idea implies that the very lowest level of all must have distinct building blocks, but so far we have got down to 'fields', which seem to be a sort of 'foam'.
27. Natural Reality / B. Modern Physics / 4. Standard Model / a. Concept of matter
Only four particles are needed for matter: up and down quark, electron, electron-neutrino [Watson]
     Full Idea: We need twelve particles in the master equation of the standard model, but it is necessary to have only four to build a universe (up and down quarks, the electron and the electron neutrino (or lepton). The existence of the others is 'a bit of a mystery'.
     From: Peter Watson (Convergence [2016], 11 'First Three')
27. Natural Reality / F. Chemistry / 1. Chemistry
The shape of molecules is important, as well as the atoms and their bonds [Watson]
     Full Idea: Pauling showed that the architecture - the shape of molecules was relevant (as well as the bonds). This meant that molecules were just as important as atoms in the understanding of matter. Molecules were not just the sum of their parts.
     From: Peter Watson (Convergence [2016], 05 'Three')
     A reaction: If Aristotle struggled to understand matter, then so should modern philosophers. This involves thermodynamics and chemistry, as well as quantum theory.
27. Natural Reality / G. Biology / 2. Life
In 1828 the animal substance urea was manufactured from inorganic ingredients [Watson]
     Full Idea: In 1828 Wöhler, in an iconic experiment, had manufactured an organic substance, urea, hitherto the product solely of animals, out of inorganic materials, and without any interventions of vital force.
     From: Peter Watson (Convergence [2016], 06 'Inorganic')
     A reaction: For reductionists like me, the gradual explanation of life in inorganic terms is the great role model of explanation. I take it for granted that the human mind will go the same way, despite partisan resistance from a lot of philosophers.
Information is physical, and living can be seen as replicating and preserving information [Watson]
     Full Idea: In passing information, physical changes take place, and information is thus physical. On this account, the act of living can be seen as replicating and preserving the information that a living body is comprised of.
     From: Peter Watson (Convergence [2016], 17 'Dreams')
     A reaction: [He emphasises 'the act' of living, rather than a life]
27. Natural Reality / G. Biology / 3. Evolution
DNA mutation suggests humans and chimpanzees diverged 6.6 million years ago [Watson]
     Full Idea: The basic mutation rate in DNA is 0.71 percent per million years. Working back from the present difference between human and chimpanzee DNA, we arrive at 6.6 million years ago for their divergence.
     From: Peter Watson (Ideas [2005], Ch.01)
     A reaction: This database is committed to evolution (a reminder that even databases have commitments), and so facts of this kind are included, even though they are not strictly philosophical. All complaints should be inwardly digested and forgotten.
28. God / C. Attitudes to God / 4. God Reflects Humanity
During the rise of civilizations, the main gods changed from female to male [Watson]
     Full Idea: Around the time of the rise of the first great civilizations, the main gods changed sex, as the Great Goddess, or a raft of smaller goddesses, were demoted and male gods took their place.
     From: Peter Watson (Ideas [2005], Ch.05)
     A reaction: Why? War, perhaps?
29. Religion / A. Polytheistic Religion / 3. Hinduism
Hinduism has no founder, or prophet, or creed, or ecclesiastical structure [Watson]
     Full Idea: Traditional Hinduism has been described as more a way of living than a way of thought; it has no founder, no prophet, no creed and no ecclesiastical structure.
     From: Peter Watson (Ideas [2005], Ch.05)
     A reaction: This contrast strikingly with all later religions, which felt they had to follow the Jews in becoming a 'religion of the book', with a sacred text, and hence a special status for the author(s) of that text.
29. Religion / B. Monotheistic Religion / 2. Judaism
Monotheism was a uniquely Israelite creation within the Middle East [Watson]
     Full Idea: No one questions the fact that monotheism was a uniquely Israelite creation within the Middle East.
     From: Peter Watson (Ideas [2005], Ch.07)
     A reaction: I take the Middle East to exclude Greece, where they were developing similar ideas. Who knows?
Modern Judaism became stabilised in 200 CE [Watson]
     Full Idea: The Judaism we know today didn't become stabilized until roughly 200 CE.
     From: Peter Watson (Ideas [2005], Ch.07)
     A reaction: By that stage it would have been subject to the influences of Christianity, ancient Greek philosophy, and neo-Platonism.
The Israelites may have asserted the uniqueness of Yahweh to justify land claims [Watson]
     Full Idea: Archaeology offers datable figures that seem to support the idea that the Israelites of the 'second exile' period converted Yahweh into a special, single God to justify their claims to the land.
     From: Peter Watson (Ideas [2005], Ch.07)
     A reaction: The implications for middle eastern politics of this wicked observation are beyond the remit of a philosophy database.
29. Religion / B. Monotheistic Religion / 3. Zoroastrianism
The Gathas (hymns) of Zoroastrianism date from about 1000 BCE [Watson]
     Full Idea: The Gathas, the liturgical hymns that make up the 'Avesta', the Zoroastrian canon, are very similar in language to the oldest Sanskrit of Hinduism, so they are not much younger than 1200 BCE.
     From: Peter Watson (Ideas [2005], Ch.05)
     A reaction: This implies a big expansion of religion before the well-known expansion of the sixth century BCE.
Zoroaster conceived the afterlife, judgement, heaven and hell, and the devil [Watson]
     Full Idea: Life after death, resurrection, judgement, heaven and paradise, were all Zoroastrian firsts, as were hell and the devil.
     From: Peter Watson (Ideas [2005], Ch.05)
     A reaction: He appears to be the first 'prophet'.
29. Religion / B. Monotheistic Religion / 4. Christianity / a. Christianity
Jesus never intended to start a new religion [Watson]
     Full Idea: Jesus never intended to start a new religion.
     From: Peter Watson (Ideas [2005], Ch.08)
     A reaction: An intriguing fact, which makes you wonder whether any of the prophets ever had such an intention.
Paul's early writings mention few striking episodes from Jesus' life [Watson]
     Full Idea: Paul's writings - letters mainly - predate the gospels and yet make no mention of many of the more striking episodes that make up Jesus' life.
     From: Peter Watson (Ideas [2005], Ch.07)
     A reaction: This is not proof of anything, but it seems very significant if we are trying to get at the facts about Jesus.
29. Religion / C. Spiritual Disciplines / 1. Confucianism
Confucius revered the spiritual world, but not the supernatural, or a personal god, or the afterlife [Watson]
     Full Idea: Confucius was deeply religious in a traditional sense, showing reverence towards heaven and an omnipresent spiritual world, but he was cool towards the supernatural, and does not seem to have believed in either a personal god or an afterlife.
     From: Peter Watson (Ideas [2005], Ch.05)
     A reaction: The implication is that the spiritual world was very remote from us, and beyond communication. Sounds like deism.
29. Religion / C. Spiritual Disciplines / 2. Taoism
Taoism aims at freedom from the world, the body, the mind, and nature [Watson]
     Full Idea: Underlying Taoism is a search for freedom - from the world, from the body, from the mind, from nature.
     From: Peter Watson (Ideas [2005], Ch.05)
     A reaction: Of all the world's religions, I think Taoism is the most ridiculouly misconceived.
29. Religion / D. Religious Issues / 1. Religious Commitment / a. Religious Belief
The three basic ingredients of religion are: the soul, seers or priests, and ritual [Watson]
     Full Idea: Anthropologist distinguish three requirements for religion: a non-physical soul which can survive death; individuals who can receive supernatural inspiration; and rituals which can cause changes in the present world.
     From: Peter Watson (Ideas [2005], Ch.01)
     A reaction: The latter two, of course, also imply belief in supernatural powers.
29. Religion / D. Religious Issues / 2. Immortality / a. Immortality
In ancient Athens the souls of the dead are received by the 'upper air' [Watson]
     Full Idea: An official Athenian war monument of 432 BCE says the souls of the dead will be received by the aither (the 'upper air'), though their bodies remain on earth.
     From: Peter Watson (Ideas [2005], Ch.05)
     A reaction: Intriguing. Did they think anything happened when they got there? There are also ideas about Hades, and the Isles of the Blessed floating around.
