| 6012 | We must choose in which of the virtues we wish to excel [Panaetius] |
| Full Idea: Humans have four roles in life, of which the fourth involves choices, of career, and of the virtue in which one wishes to excel. | |
| From: Panaetius (fragments/reports [c.145 BCE]), quoted by Elizabeth Asmis - Panaetius | |
| A reaction: Panaetius strikes me as exceptionally wise. A big gap in Aristotle is the fact that we cannot excel in all virtues, and that therefore some choice is required. By what criteria? We have the Gauguin problem (excel in one, disgraceful in the others). |
| 6013 | Panaetius said we should live according to our natural starting-points [Panaetius, by Asmis] |
| Full Idea: Panaetius reformulated the Stoic goal as living in accordance with the starting-points given to us by nature. | |
| From: report of Panaetius (fragments/reports [c.145 BCE]) by Elizabeth Asmis - Panaetius | |
| A reaction: This sounds remarkably like the substitution of meritocratic equality of opportunity for communistic actual equality. In other words, it doesn't sound very Stoic. 'Live according to nature' implies more restraint than this ambitious version. |
| 6014 | Panaetius identified courage with great-mindedness, preferring civic courage to military [Panaetius, by Asmis] |
| Full Idea: Panaetius recast the virtue of courage as 'greatmindedness' (Aristotle's paramount virtue), he demoted military valour and gave priority to courage displayed in civic life. | |
| From: report of Panaetius (fragments/reports [c.145 BCE]) by Elizabeth Asmis - Panaetius | |
| A reaction: I find this very appealing, as I am increasingly horrified by our denigration of the people who implement our democracy for us. We urgently need to get back to the Greek idea of civic virtue, and this idea of Panaetius should be widely promulgated. |
| 20489 | Human beings can never really flourish in a long-term state of nature [Wolff,J] |
| Full Idea: We must agree with Hobbes, Locke and Rousseau that nothing genuinely worthy of being called a state of nature will, at least in the long term, be a condition in which human beings can flourish. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 1 'Conc') | |
| A reaction: Given our highly encultured concept of modern flourishing, that is obviously right. There may be another reality where hom sap flourishes in a quite different and much simpler way. Education as personal, not institutional? |
| 20483 | Collective rationality is individuals doing their best, assuming others all do the same [Wolff,J] |
| Full Idea: We need to distinguish between individual and collective rationality. Collective rationality is what is best for each individual, on the assumption that everyone else will act the same way. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 1 'Hobbes') | |
| A reaction: Wolff is surmising what lies behind Hobbes's Laws of Nature (which concern collective rationality). The Prisoner's Dilemma is the dramatisation of this distinction. I would making the teaching of the distinction compulsory in schools. |
| 20532 | Should love be the first virtue of a society, as it is of the family? [Wolff,J] |
| Full Idea: Love, or at least affection, not justice, is the first virtue of the family. Should mutual affection also be the first virtue of social and political institutions? | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 6 'Transcending') | |
| A reaction: Surely this ideal should be at the heart of any society, no matter how far away from the ideal it is pushed by events and failures of character? I take 'respect' to be the form of love we feel for strangers. |
| 20490 | For utilitarians, consent to the state is irrelevant, if it produces more happiness [Wolff,J] |
| Full Idea: On the utilitarian account the state is justified if and only if it produces more happiness than any alternative. Whether we consent to the state is irrelevant. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 2 'Intro') | |
| A reaction: The paternalistic character of utilitarianism is a familiar problem. I quite like this approach, even though liberals will find it a bit naughty. We make children go to school, for their own good. Experts endorse society, even when citizens don't. |
| 20493 | Social contract theory has the attracton of including everyone, and being voluntary [Wolff,J] |
| Full Idea: Social contract theory ...satisfies the twin demands of universalism - every person must be obligated - and voluntarism - political obligations can come into existence only through consent. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 2 'Voluntaristic') | |
| A reaction: I'm going off the idea that being a member of large society is voluntary. It can't possibly be so for most people, and it shouldn't be. I'm British, and society expects me to remain so (though they might release me, if convenient). |
| 20494 | Maybe voting in elections is a grant of legitimacy to the winners [Wolff,J] |
| Full Idea: One thought is that consent to government is communicated via the ballot-box. In voting for the government we give it our consent. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 2 'Voluntaristic') | |
| A reaction: Hm. This may be a strong positive reason why some people refuse to vote. We shouldn't load voting with such heavy commitments. It's just 'given the current situation, who will be temporarily in charge'. |
| 20500 | We can see the 'general will' as what is in the general interest [Wolff,J] |
| Full Idea: The general will demands the policy which is equally in everyone's interests. Thus we can think of the general will as the general interest. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 3 'Rousseau') | |
| A reaction: That seems to assume that the people know what is in their interests. Rousseau's General Will mainly concerns who governs, and their mode of government, but not details of actual policy. |
| 20497 | How can dictators advance the interests of the people, if they don't consult them about interests? [Wolff,J] |
| Full Idea: Even if a dictator wants to advance the interests of the people, how are those interests to be known? In a democracy people show their interests, it seems, by voting: they vote for what they want. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 3 'Knowledge') | |
| A reaction: I suppose a wise and kind despot could observe very carefully, and understand the interests of the people better than they do themselves. Indeed, I very much doubt, in 2017, whether the people know what is good for them. |
| 20506 | 'Separation of powers' allows legislative, executive and judicial functions to monitor one another [Wolff,J] |
| Full Idea: The Federalists took the idea of 'separation of powers' from Locke and Montesquieu. This places the legislative, executive and judicial functions in independent hands, so that in theory any branch of government would be checked by the other two. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 3 'Representative') | |
| A reaction: [The American Federalist writers of 1787-8 were Madison, Hamilton and Jay] This is a brilliant idea. An interesting further element that has been added to it is the monitoring by a free press, presumably because the other three were negligent. |
| 20530 | Political choice can be by utility, or maximin, or maximax [Wolff,J] |
| Full Idea: Political choices can be made by the utility principles (maximising total utility), or maximin (maximising for the worst off, a view for pessimists), or maximax (not serious, but one for optimists, being unequal, and aiming for a high maximum). | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 5 'Choosing') | |
| A reaction: [my summary of a page of Wolff] Rawls embodies the maximin view. Wolff implies that we must choose between utilitarianism and Rawls. Would Marxists endorse maximin? He also adds 'constrained maximisation', with a safety net. |
| 20487 | A realistic and less utopian anarchism looks increasingly like liberal democracy [Wolff,J] |
| Full Idea: As the anarchist picture of society becomes increasingly realistic and less utopian, it also becomes increasingly difficult to tell it apart from a liberal democratic state. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 1 'Anarchism') | |
| A reaction: Nice challenge to anarchism, which is clear in what it opposes, but isn't much of a political philosophy if it doesn't have positive aspirations. Anarchists may hope that people will beautifully co-operate, but what if they re-form the state to do it? |
| 20488 | It is hard for anarchists to deny that we need experts [Wolff,J] |
| Full Idea: Many anarchists have accepted the need for the authority of experts within society | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 1 'Anarchism') | |
| A reaction: The status of experts may be the hottest topic in contemporary politics, given the contempt for experts shown by Trump, and by the Brexit campaign of 2016. It is a nice point that even anarchists can't duck the problem. |
| 20529 | Utilitarianism probably implies a free market plus welfare [Wolff,J] |
| Full Idea: A utilitarian political philosophy would probably be a free market with a welfare state. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 5 'Choosing') | |
| A reaction: This is roughly how Britain became, after the welfare state was added to Millian liberalism. What's missing from this formula is some degree of control of the free market, to permit welfare. |
| 20510 | A system of democracy which includes both freedom and equality is almost impossible [Wolff,J] |
| Full Idea: We are very unlikely to be able to find an instrumental defence of democracy which also builds the values of freedom and equality into a feasible system. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 3 'Conc') | |
| A reaction: I increasingly think that freedom is the most overrated political virtue (though it is certainly a virtue). Total freedom is ridiculous, but the aim of sacrificing many other social goods in order to maximise freedom also looks wrong. |
| 20511 | Democracy expresses equal respect (which explains why criminals forfeit the vote) [Wolff,J] |
| Full Idea: Democracy is a way of expressing equal respect for all, which is perhaps why we withdraw the vote from criminals: by their behaviour they forfeit the right to equal respect. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 3 'Conc') | |
| A reaction: I disagree, and he has converted me to franchise for criminals. One-off criminals do not forfeit my respect for them as people, though their action may merit a controlling response on our part. Bad character, not a bad action, forfeits respect. |
| 20502 | Democracy has been seen as consistent with many types of inequality [Wolff,J] |
| Full Idea: Greeks assumed democracy was consistent with slavery, Rousseau that it was consistent with sexual inequality, and Wollstonecraft that it was consistent with disenfranchisement of the poor. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 3 'Freedom') | |
| A reaction: If you are allowed to restrict the franchise in some way, then a narrow oligarchy can qualify as a democracy, with half a dozen voters. |
| 20496 | A true democracy could not tolerate slavery, exploitation or colonialism [Wolff,J] |
| Full Idea: A democratic state has power only over the people who make up the electorate. Ruling over a subservient class, or territory, is claimed to be antithetical to the true ideals of democracy. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 3 'Intro') | |
| A reaction: Is making trade deals very favourable to yourself (i.e. good capitalism) antithetical to democracy? |
| 20498 | We should decide whether voting is for self-interests, or for the common good [Wolff,J] |
| Full Idea: To avoid mixed-motivation voting, we must choose between one model of people voting in accordance with their preferences, and another of voting for their estimate of the common good. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 3 'Voting') | |
| A reaction: Personally I always voted for the common good, and only slowly realised that most people were voting for their own interests. A rational society would at least bring this dichotomy into the open. Voting for self-interest isn't wicked. |
| 20499 | Condorcet proved that sensible voting leads to an emphatically right answer [Wolff,J] |
| Full Idea: Condorcet proved that provided people have a better than even chance of getting the right answer, and that they vote for their idea of the common good, then majority decisions are an excellent way to get the right result. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 3 'Voting') | |
| A reaction: [compressed] The point is that collective voting magnifies the result. If they tend to be right, the collective view is super-right. But if they tend towards the wrong, the collective view goes very wrong indeed. History is full of the latter. |
| 20509 | Occasional defeat is acceptable, but a minority that is continually defeated is a problem [Wolff,J] |
| Full Idea: Most of us can accept losing from time to time, but sometimes an entrenched majority will win vote after vote, leaving the minority group permanently outvoted and ignored. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 3 'Protecting') | |
| A reaction: This is the key problem of the treatment of minorities in a democracy. Personally I have only once been on the winning side in voting for my MP, and he changed party a couple of years later. |
| 20524 | Market prices indicate shortages and gluts, and where the profits are to be made [Wolff,J] |
| Full Idea: The price system is a way of signalling and transmitting information. The fact that the price of a good rises shows that the good is in short supply. And if prices rise in a sector because of increasing demand, then new producers rush in for the profits. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 5 'Free') | |
| A reaction: [Woff is discussing Hayek] Why do we have a shortage of decent housing in the UK? Centralised economies lack this direct way of discovering where their efforts should be directed. |
| 20518 | Liberty principles can't justify laws against duelling, incest between siblings and euthanasia [Wolff,J] |
| Full Idea: Many laws of contemporary society are very hard to defend in terms of Mill's Liberty Principle, such as laws against duelling, incest between siblings, and euthanasia. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 4 'Poison') | |
| A reaction: [He cites Chief Justice Lord Devlin for this] Being killed in a duel can cause widespread misery. Fear of inbreeding is behind the second one, and fear of murdering the old behind the third one. No man is an island. |
| 20531 | Either Difference allows unequal liberty, or Liberty makes implementing Difference impossible [Wolff,J] |
| Full Idea: Critics say that the Difference Principle allows inequality of liberty ...and (more often) that liberty means we cannot impose any restriction on individual property holdings. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 5 'Nozick') | |
| A reaction: The second objection is associated with Robert Nozick. The point is that you can implement the Difference Principle without restricting liberty. The standard right-wing objection of social welfare. |
| 20526 | Utilitarians argue for equal distribution because of diminishing utility of repetition [Wolff,J] |
| Full Idea: The utilitarian argument for equality assumes that people have 'diminishing marginal returns' for goods. If there are two people and two nice chocolate biscuits, then utilitarianism is likely to recommend one each. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 5 'Arguments') | |
| A reaction: The point is that the second biscuit provides slightly diminished pleasure. This is why you can buy boxes of assorted biscuits, which you are then not required to share. |
| 20528 | Difference Principle: all inequalities should be in favour of the disadvantaged [Wolff,J] |
| Full Idea: Difference Principle: Social and economic inequalities are to be arranged so that they are to the greatest benefit of the least advantaged. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 5 'Choosing') | |
| A reaction: Rivals would say that inequalities should go to those who have earned them. |
| 20503 | Political equality is not much use without social equality [Wolff,J] |
| Full Idea: As Marx observed, and as women have learnt to their cost, equal political rights are worth fighting for, but they are of little value if one is still treated unequally in day-to-day life. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 3 'Participatory') | |
| A reaction: In fact social equality comes first, because that will imply political equality and financial justice. I think it is all covered under the virtue of 'respect', which should have pre-eminence in both public and private life. |
| 20512 | Standard rights: life, free speech, assembly, movement, vote, stand (plus shelter, food, health?) [Wolff,J] |
| Full Idea: The normal liberal basic rights are right to life, free speech, free assembly and freedom of movement, plus the rights to vote and stand for office. Some theorists add the right to a decent living standard (shelter, food and health care). | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 4 'Liberty') | |
| A reaction: I think he has forgotten to add education. In Britain Beatrice Webb seems to have single-handedly added the living standard group to the list. |
| 20513 | If natural rights are axiomatic, there is then no way we can defend them [Wolff,J] |
| Full Idea: The theory of basic natural rights is problematic, because although the theory is rigorous and principled, the disadvantage is that we are left with nothing more fundamental to say in defence of these rights. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 4 'Liberty') | |
| A reaction: This is a nice point about anything which is treated as axiomatic - even Euclid's geometry. Presumably rights can only be justified by the needs of our shared human nature. |
| 20514 | If rights are natural, rather than inferred, how do we know which rights we have? [Wolff,J] |
| Full Idea: If natural rights have a fundamental status, and so are not arrived at on the basis of some other argument, how do we know what rights we have? | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 4 'Liberty') | |
| A reaction: He cites Bentham as using this point. Utilitarianism at least provides a grounding for the identification of possible basic rights. Start from what we want, or what we more objectively need? Human needs, or needs in our present culture? |
| 20522 | Utilitarians might say property ownership encourages the best use of the land [Wolff,J] |
| Full Idea: A utilitarian justification of property rights says allowing people to appropriate property, trade in it, and leave it to their descendants will encourage them to make the most productive use of their resources. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 5 'Locke') | |
| A reaction: This obviously has a point, but equally justifies confiscation of land from people who are not making best use of it. In Sicily many landowners refused to allow the peasants to make any use at all of the land. |
| 20534 | Rights and justice are only the last resorts of a society, something to fall back on [Wolff,J] |
| Full Idea: Justice is the last virtue of society, or at least the last resort. Rights, or considerations of justice, are like an insurance policy: something offering security to fall back on. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 6 'Transcending') | |
| A reaction: I like this. He points out that a good family doesn't talk of rights and justice. We want a friendly harmonious society, with safety nets. |
| 20492 | Following some laws is not a moral matter; trivial traffic rules, for example [Wolff,J] |
| Full Idea: Some laws have little grounding in morality. You may believe you have a moral obligation to stop at a red light at a deserted crossroads, but only because that is what the law tells you to do. | |
| From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 2 'Goal') | |
| A reaction: I would have thought such a law was wholly grounded in the morality of teamwork. It is the problem of rule utilitarianism, and also a problem about virtuous character. The puzzle is not the law, but the strict obedience to it. |
| 20624 | Work degrades into heat, but not vice versa [Close] |
| Full Idea: William Thomson, Lord Kelvin, declared (in 1865) the second law of thermodynamics: mechanical work inevitably tends to degrade into heat, but not vice versa. | |
| From: Frank Close (Theories of Everything [2017], 3 'Perpetual') | |
| A reaction: The basis of entropy, which makes time an essential part of physics. Might this be the single most important fact about the physical world? |
| 20623 | First Law: energy can change form, but is conserved overall [Close] |
| Full Idea: The first law of thermodynamics : energy can be changed from one form to another, but is always conserved overall. | |
| From: Frank Close (Theories of Everything [2017], 3 'Perpetual') | |
| A reaction: So we have no idea what energy is, but we know it's conserved. (Daniel Bernoulli showed the greater the mean energy, the higher the temperature. James Joule showed the quantitative equivalence of heat and work p.26-7) |
| 20625 | Third Law: total order and minimum entropy only occurs at absolute zero [Close] |
| Full Idea: The third law of thermodynamics says that a hypothetical state of total order and minimum entropy can be attained only at the absolute zero temperature, minus 273 degrees Celsius. | |
| From: Frank Close (Theories of Everything [2017], 3 'Arrow') | |
| A reaction: If temperature is energetic movement of atoms (or whatever), then obviously zero movement is the coldest it can get. So is absolute zero an energy state, or an absence of energy? I have no idea what 'total order' means. |
| 20622 | All motions are relative and ambiguous, but acceleration is the same in all inertial frames [Close] |
| Full Idea: There is no absolute state of rest; only relative motions are unambiguous. Contrast this with acceleration, however, which has the same magnitude in all inertial frames. | |
| From: Frank Close (Theories of Everything [2017], 3 'Newton's') | |
| A reaction: It seems important to remember this, before we start trumpeting about the whole of physics being relative. ....But see Idea 20634! |
| 20628 | The electric and magnetic are tightly linked, and viewed according to your own motion [Close] |
| Full Idea: Electric and magnetic phenomena are profoundly intertwined; what you interpret as electric or magnetic thus depends on your own motion. | |
| From: Frank Close (Theories of Everything [2017], 3 'Light!') | |
| A reaction: This sounds like an earlier version of special relativity. |
| 20635 | The general relativity equations relate curvature in space-time to density of energy-momentum [Close] |
| Full Idea: The essence of general relativity relates 'curvature in space-time' on one side of the equation to the 'density of momentum and energy' on the other. ...In full, Einstein required ten equations of this type. | |
| From: Frank Close (Theories of Everything [2017], 5 'Gravity') | |
| A reaction: Momentum involves mass, and energy is equivalent to mass (e=mc^2). |
| 20627 | Electric fields have four basic laws (two by Gauss, one by Ampère, one by Faraday) [Close] |
| Full Idea: Four basic laws of electric and magnetic fields: Gauss's Law (about the flux produced by a field), Gauss's law of magnets (there can be no monopoles), Ampère's Law (fields on surfaces), and Farday's Law (accelerated magnets produce fields). | |
| From: Frank Close (Theories of Everything [2017], 3 'Light!') | |
| A reaction: [Highly compressed, for an overview. Close explains them] |
| 20630 | Light isn't just emitted in quanta called photons - light is photons [Close] |
| Full Idea: Planck had assumed that light is emitted in quanta called photons. Einstein went further - light is photons. | |
| From: Frank Close (Theories of Everything [2017], 3 'Light!') | |
| A reaction: The point is that light travels as entities which are photons, rather than the emissions being quantized packets of some other stuff. |
| 20637 | In general relativity the energy and momentum of photons subjects them to gravity [Close] |
| Full Idea: In Einstein's general theory, gravity acts also on energy and momentum, not simply on mass. For example, massless photons of light feel the gravitational attraction of the Sun and can be deflected. | |
| From: Frank Close (Theories of Everything [2017], 5 'Planck') | |
| A reaction: Ah, a puzzle solved. How come massless photons are bent by gravity? |
| 20629 | Electro-magnetic waves travel at light speed - so light is electromagnetism! [Close] |
| Full Idea: Faradays' measurements predicted the speed of electro-magnetic waves, which happened to be the speed of light, so Maxwell made an inspired leap: light is an electromagnetic wave! | |
| From: Frank Close (Theories of Everything [2017], 3 'Light!') | |
| A reaction: Put that way, it doesn't sound like an 'inspired' leap, because travelling at exactly the same speed seems a pretty good indication that they are the same sort of thing. (But I'm not denying that Maxwell was a special guy!) |
| 20632 | In QED, electro-magnetism exists in quantum states, emitting and absorbing electrons [Close] |
| Full Idea: Dirac created quantum electrodynamics (QED): the universal electro-magnetic field can exist in discreet states of energy (with photons appearing and disappearing by energy excitations. This combined classical ideas, quantum theory and special relativity. | |
| From: Frank Close (Theories of Everything [2017], 3 'Light!') | |
| A reaction: Close says this is the theory of everything in atomic structure, but not in nuclei (which needs QCD and QFD). So if there are lots of other 'fields' (e.g. gravitational, weak, strong, Higgs), how do they all fit together? Do they talk to one another? |
| 20642 | Photon exchange drives the electro-magnetic force [Close] |
| Full Idea: The exchange of photons drives the electro-magnetic force. | |
| From: Frank Close (Theories of Everything [2017], 6 'Superstrings') | |
| A reaction: So light, which we just think of as what is visible, is a mere side-effect of the engine room of nature - the core mechanism of the whole electro-magnetic field. |
| 20639 | Quantum fields contain continual rapid creation and disappearance [Close] |
| Full Idea: Quantum field theory implies that the vacuum of space is filled with particles and antiparticles which bubble in and out of existence on faster and faster timescales over shorter and shorter distances. | |
| From: Frank Close (Theories of Everything [2017], 6 'Intro') | |
| A reaction: Ponder this sentence until you head aches. Existence, but not as we know it, Jim. Close says calculations in QED about the electron confirm this. |
| 20641 | Electrons get their mass by interaction with the Higgs field [Close] |
| Full Idea: The electron gets its mass by interaction with the ubiquitous Higgs field. | |
| From: Frank Close (Theories of Everything [2017], 6 'Hierarchy') | |
| A reaction: I thought I understood mass until I read this. Is it just wrong to say the mass of a table is the 'amount of stuff' in it? |
| 20631 | Dirac showed how electrons conform to special relativity [Close] |
| Full Idea: In 1928 Paul Dirac discovered the quantum equation that describes the electron and conforms to the requirements special relativity theory. | |
| From: Frank Close (Theories of Everything [2017], 3 'Light!') | |
| A reaction: This sounds like a major step in the unification of physics. Quantum theory and General relativity remain irreconcilable. |
| 20626 | Modern theories of matter are grounded in heat, work and energy [Close] |
| Full Idea: The link between temperature, heat, work and energy is at the root of our historical ability to construct theories of matter, such as Newton's dynamics, while ignoring, and indeed being ignorant of - atomic dimensions. | |
| From: Frank Close (Theories of Everything [2017], 3 'Arrow') | |
| A reaction: That is, presumably, that even when you fill in the atoms, and the standard model of physics, these aspects of matter do the main explaiining (of the behaviour, rather than of the structure). |
| 20633 | The Higgs field is an electroweak plasma - but we don't know what stuff it consists of [Close] |
| Full Idea: In 2012 it was confirmed that we are immersed in an electroweak plasma - the Higgs field. We curently have no knowledge of what this stuff might consist of. | |
| From: Frank Close (Theories of Everything [2017], 4 'Higgs') | |
| A reaction: The second sentence has my full attention. So we don't understand a field properly until we understand the 'stuff' it is made of? So what are all the familiar fields made of? Tell me more! |
| 20640 | Space-time is indeterminate foam over short distances [Close] |
| Full Idea: At very short distances, space-time itself becomes some indeterminate foam. | |
| From: Frank Close (Theories of Everything [2017], 6 'Intro') | |
| A reaction: [see Close for a bit more detail of this weird idea] |
| 5888 | Souls are born, since they are sensitive and inherited, so they must perish [Panaetius, by Cicero] |
| Full Idea: Panaetius says that whatever is born must perish, and souls are clearly born, as shown by the resemblance of children to their parents in disposition as well as body; also, anything sensible of pain is susceptible to sickness, and hence perishes. | |
| From: report of Panaetius (fragments/reports [c.145 BCE]) by M. Tullius Cicero - Tusculan Disputations I.xxxii | |
| A reaction: These seem to be rather good arguments. If we actually observe what someone's soul is like (through character) it seems rooted in a family and culture, and it certainly seems susceptible to disease. An empirical approach. |
