| 17809 | Gödel showed that the syntactic approach to the infinite is of limited value [Kreisel] |
| Full Idea: Usually Gödel's incompleteness theorems are taken as showing a limitation on the syntactic approach to an understanding of the concept of infinity. | |
| From: Georg Kreisel (Hilbert's Programme [1958], 05) |
| 17810 | The study of mathematical foundations needs new non-mathematical concepts [Kreisel] |
| Full Idea: It is necessary to use non-mathematical concepts, i.e. concepts lacking the precision which permit mathematical manipulation, for a significant approach to foundations. We currently have no concepts of this kind which we can take seriously. | |
| From: Georg Kreisel (Hilbert's Programme [1958], 06) | |
| A reaction: Music to the ears of any philosopher of mathematics, because it means they are not yet out of a job. |
| 22370 | Big central government only exists as a focus for anger - not to act [Fisher] |
| Full Idea: The specter of big government is there to be blamed precisely for its failure to act as a centralising power, the anger directed at it much like the fury Thomas Hardy supposedly spat at God for not existing. | |
| From: Mark Fisher (Capitalist Realism [2009], 8) | |
| A reaction: The point is that the power resides with the leaders of capitalism, and central government is largely a side-show. Sounds somewhat true, and the politicians are largely unaware of their role. |
| 22368 | It is hard to imagine the end of capitalism [Fisher] |
| Full Idea: It is easier to imagine the end of the world than it is to imagine the end of capitalism. | |
| From: Mark Fisher (Capitalist Realism [2009], 1) | |
| A reaction: His book addresses the question of whether complacently accepting capitalism is the right attitude. I read it because I am complacently resigned to living with capitalism. If we started again, would capitalism be a rational choice? |
| 22369 | Are students consumers or products of education? [Fisher] |
| Full Idea: Are students the consumers of education, or its product? | |
| From: Mark Fisher (Capitalist Realism [2009], 6) | |
| A reaction: As a teacher I have been increasingly obliged to treat pupils as customers, meaning that my main task is to keep them happy. Admittedly, pupils who are interested are usually happy pupils, but as a main objective happiness seems wrong. |
| 14586 | Physical causation consists in transference of conserved quantities [Dowe, by Mumford/Anjum] |
| Full Idea: For Dowe physical causation consists in transference of conserved quantities. | |
| From: report of Phil Dowe (Physical Causation [2000]) by S.Mumford/R.Lill Anjum - Getting Causes from Powers 10.2 | |
| A reaction: [see Psillos 2002 on this] This is evidently a modification of the idea of physical causation as energy-transfer, but narrowing it down to exclude trivial cases. I guess. Need better physics. |
| 4787 | Causation interaction is an exchange of conserved quantities, such as mass, energy or charge [Dowe, by Psillos] |
| Full Idea: Dowe argues that a 'causal process' is a world line of an object with a conserved quantity (such as mass, energy, momentum, charge), and a 'causal interaction' is an exchange between two such objects. | |
| From: report of Phil Dowe (Physical Causation [2000]) by Stathis Psillos - Causation and Explanation §4.4 | |
| A reaction: This looks very promising. Nice distinction between causal process and causal interaction. 'Conserved quantities' is better physics than just 'energy'. We can hand causation over to the scientist? |
| 4788 | Dowe commends the Conserved Quantity theory as it avoids mention of counterfactuals [Dowe, by Psillos] |
| Full Idea: Dowe commends the Conserved Quantity theory because it avoids any mention of counterfactuals. | |
| From: report of Phil Dowe (Physical Causation [2000]) by Stathis Psillos - Causation and Explanation §4.4 | |
| A reaction: Clearly the truth of a counterfactual is quite a problem for an empiricist/scientist, but one needs to distinguish between reality and our grasp of it. We commit ourselves to counterfactuals, even if causation is transfer of conserved quantities. |
| 17811 | The natural conception of points ducks the problem of naming or constructing each point [Kreisel] |
| Full Idea: In analysis, the most natural conception of a point ignores the matter of naming the point, i.e. how the real number is represented or by what constructions the point is reached from given points. | |
| From: Georg Kreisel (Hilbert's Programme [1958], 13) | |
| A reaction: This problem has bothered me. There are formal ways of constructing real numbers, but they don't seem to result in a name for each one. |
