20575 | Socialist economics needs a very strong central power, virtually leading to slavery [Hayek, by Oksala] |
Full Idea: Hayek argues that socialist economic equality can only be effectively put into practice by a strong, dictatorial government. Planning has to be imposed by force, and centralised economic power creates a dependency scarcely distingishable from slavery. | |
From: report of F.A. Hayek (The Road to Serfdom [1944]) by Johanna Oksala - Political Philosophy: all that matters Ch.7 | |
A reaction: I don't see much sign of the post-war British Labour government being anything like this, even though they nationalised the railways and introduce a national health service. Hayek was mesmerised by Russia. |
22599 | Hayek was a liberal, but mainly concerned with market freedom [Hayek, by Dunt] |
Full Idea: Hayek was a liberal (rather than a conservative), …but the individual liberty he cared about was not diversity or freedom of thought. It was freedom to operate in the market. | |
From: report of F.A. Hayek (The Road to Serfdom [1944]) by Ian Dunt - How to be a Liberal 7 | |
A reaction: There seems to have been a drift from obsession with freedom to participate in the market, towards the less plausible idea that market forces can solve everything. I once met someone who was convinced the market could solve environmental problems. |
22600 | Impeding the market is likely to lead to extensive state control [Hayek] |
Full Idea: Once the free working of the market is impeded beyond a certain degree, the planner will be forced to extend his controls until they become all comprehensive. | |
From: F.A. Hayek (The Road to Serfdom [1944]), quoted by Ian Dunt - How to be a Liberal 7 | |
A reaction: Hayek was terrified of totalitarianism (quite reasonably), but fascism and communism don't seem to have arisen in the way he describes. I'm not clear why sensible intervention in the market should slide down into nightmare. |
20543 | 'Social justice' is a confused idea, and inequalities need no justification [Hayek, by Swift] |
Full Idea: Hayek thinks the whole idea of social justice involves a philosophical mistake, so that inequality doesn't really need justification in the first place. | |
From: report of F.A. Hayek (The Mirage of Social Justice [1976]) by Adam Swift - Political Philosophy (3rd ed) 1 'Conc' | |
A reaction: It is certainly hard to justify the claim that the state of nature involves equality, making its disturbance in need of justification. But surely inequalities in government policy (such as differential income tax) need justification? |
24162 | Planck introduced the idea that energy can be quantized [Baggott] |
Full Idea: By deriving his radiation law, Planck had inadvertently introduced the idea that energy itself could be 'quantized'. | |
From: Jim Baggott (The Quantum Story: 40 moments [2011], 01) | |
A reaction: He earlier assumed energy is continuously variable. I presume this means that the older idea of energy is now subsumed into the concept of fields, which are quantized into particles. The powers of nature are found in the fields. |
21731 | Fields can be 'scalar', or 'vector', or 'tensor', or 'spinor' [Baggott] |
Full Idea: Fields can be 'scalar', with no particular direction (pointing, but not pushing or pulling); or 'vector', with a direction (like magnetism, or Newtonian gravity); or 'tensor' (needing further parameters); or 'spinor' (depending on spin orientation). | |
From: Jim Baggott (Farewell to Reality: fairytale physics [2013], 2 'Quantum') | |
A reaction: [compressed] So the question is, why do they differ? What is it in the nature of each field the result in a distinctive directional feature? |
21730 | A 'field' is a property with a magnitude, distributed across all of space and time [Baggott] |
Full Idea: A 'field' is defined in terms of the magnitude of some physical property distributed over every point in time and space. | |
From: Jim Baggott (Farewell to Reality: fairytale physics [2013], 2 'Quantum') | |
A reaction: If it involves a 'property', normal usage entails that there is some entity which possesses the property. So what's the entity? Eh? Eh? You don't know! Disappointed... |
24163 | Free electrons have clouds of virtual particles, arising from field interaction [Baggott] |
Full Idea: A free electron doesn't simply persist as a point particle travelling along a predetermined, classical path; it is surrounded by a swarm of virtual particles arsising from self-interactions with its own magnetic field. | |
From: Jim Baggott (The Quantum Story: 40 moments [2011], 19) | |
A reaction: It seems to me important for amateurs and mere philosophers to hang on to this idea of virtual particles, because they undermine any attempt to impose a macro picture on sub-atomic events. |
24161 | Thermodynamics sees nature as a continuous flow of energy, as radiation and as substance [Baggott] |
Full Idea: Thermodynamics reinforced a vision of nature as one of harmonious flow. Energy, which could be neither created nor destroyed, flowed continuously between radiation and material substance, in themselves unbroken continua. | |
From: Jim Baggott (The Quantum Story: 40 moments [2011], 01) | |
A reaction: Interestingly, Einstein's Special Relativity e = mc2 seems to endorse this view, by equation energy and mass. I've always wanted to know what energy is, but no one seems to know. |
21732 | The current standard model requires 61 particles [Baggott] |
Full Idea: The current model requires 61 particles: three generations of two leptons and two flavours of quark, in three different colours (making 24); the anti-particles of all of these (48); 12 force particles (photon, W1, Z0, 8 gluons), and a Higgs boson. | |
From: Jim Baggott (Farewell to Reality: fairytale physics [2013], 6 n) |
24160 | Particle measurements don't seem to reflect their reality [Baggott] |
Full Idea: It seems that we can no longer assume that the particle properties we measure necessarily reflect or represent the properties of the particles as they really are. | |
From: Jim Baggott (The Quantum Story: 40 moments [2011], Pref) | |
A reaction: [He cites a 2006 experiment] This gives an interesting response to the Copenhagen Interpretation - that observers appear to be creating the reality they observe, because they only have 'observations', with no reality to correspond to them. I like it. |
1513 | The Egyptians were the first to say the soul is immortal and reincarnated [Herodotus] |
Full Idea: The Egyptians were the first to claim that the soul of a human being is immortal, and that each time the body dies the soul enters another creature just as it is being born. | |
From: Herodotus (The Histories [c.435 BCE], 2.123.2) |
