| 17596 | Coherence problems have positive and negative restraints; solutions maximise constraint satisfaction [Thagard] |
| Full Idea: A coherence problem is a set of elements connected by positive and negative restraints, and a solution consists of partitioning the elements into two sets (accepted and rejected) in a way that maximises satisfaction of the constraints. | |
| From: Paul Thagard (Coherence: The Price is Right [2012], p.42) | |
| A reaction: I'm enthusiastic about this, as it begins to clarify the central activity of epistemology, which is the quest for best explanations. |
| 17597 | Coherence is explanatory, deductive, conceptual, analogical, perceptual, and deliberative [Thagard] |
| Full Idea: I propose that there are six main kinds of coherence: explanatory, deductive, conceptual, analogical, perceptual, and deliberative. ...Epistemic coherence is a combination of the first five kinds, and ethics adds the sixth. | |
| From: Paul Thagard (Coherence: The Price is Right [2012], p.43) | |
| A reaction: Wonderful. Someone is getting to grips with the concept of coherence, instead of just whingeing about how vague it is. |
| 17598 | Explanatory coherence needs symmetry,explanation,analogy,data priority, contradiction,competition,acceptance [Thagard] |
| Full Idea: Informally, a theory of explanatory coherence has the principles of symmetry, explanation, analogy, data priority, contradiction, competition and acceptance. | |
| From: Paul Thagard (Coherence: The Price is Right [2012], p.44) | |
| A reaction: [Thagard give a concise summary of his theory here] Again Thagard makes a wonderful contribution in an area where most thinkers are pessimistic about making any progress. His principles are very plausible. |
| 17602 | Verisimilitude comes from including more phenomena, and revealing what underlies [Thagard] |
| Full Idea: A scientific theory is progressively approximating the truth if it increases its explanatory coherence by broadening to more phenomena and deepening by investigating layers of mechanisms. | |
| From: Paul Thagard (Coherence: The Price is Right [2012], p.46) |
| 17601 | Neither a priori rationalism nor sense data empiricism account for scientific knowledge [Thagard] |
| Full Idea: Both rationalists (who start with a priori truths and make deductions) and empiricists (starting with indubitable sense data and what follows) would guarantee truth, but neither even begins to account for scientific knowledge. | |
| From: Paul Thagard (Coherence: The Price is Right [2012], p.46) | |
| A reaction: Thagard's answer, and mine, is inference to the best explanation, but goes beyond both the a priori truths and the perceptions. |
| 17600 | Bayesian inference is forced to rely on approximations [Thagard] |
| Full Idea: It is well known that the general problem with Bayesian inference is that it is computationally intractable, so the algorithms used for computing posterior probabilities have to be approximations. | |
| From: Paul Thagard (Coherence: The Price is Right [2012], p.45) | |
| A reaction: Thagard makes this sound devastating, but then concedes that all theories have to rely on approximations, so I haven't quite grasped this idea. He gives references. |
| 17065 | 2: An explanation must wholly cohere internally, and with the new fact [Thagard, by Smart] |
| Full Idea: 2: If a set of propositions explains a further proposition, then each proposition in the set coheres with that proposition, and propositions in the set cohere pairwise with one another. | |
| From: report of Paul Thagard (Explanatory Coherence [1989], 2) by J.J.C. Smart - Explanation - Opening Address p.04 |
| 17066 | 3: If an analogous pair explain another analogous pair, then they all cohere [Thagard, by Smart] |
| Full Idea: 3: If two analogous propositions separately explain different ones of a further pair of analogous propositions, then the first pair cohere with one another, and so do the second (explananda) pair. | |
| From: report of Paul Thagard (Explanatory Coherence [1989], 3) by J.J.C. Smart - Explanation - Opening Address p.04 |
| 17064 | 1: Coherence is a symmetrical relation between two propositions [Thagard, by Smart] |
| Full Idea: 1: Coherence and incoherence are symmetrical between pairs of propositions. | |
| From: report of Paul Thagard (Explanatory Coherence [1989], 1) by J.J.C. Smart - Explanation - Opening Address p.04 |
| 17067 | 4: For coherence, observation reports have a degree of intrinsic acceptability [Thagard, by Smart] |
| Full Idea: 4: Observation reports (for coherence) have a degree of acceptability on their own. | |
| From: report of Paul Thagard (Explanatory Coherence [1989], 4) by J.J.C. Smart - Explanation - Opening Address p.04 | |
| A reaction: Thagard makes this an axiom, but Smart rejects that and says there is no reason why observation reports should not also be accepted because of their coherence (with our views about our senses etc.). I agree with Smart. |
| 17068 | 5: Contradictory propositions incohere [Thagard, by Smart] |
| Full Idea: 5: Contradictory propositions incohere. | |
| From: report of Paul Thagard (Explanatory Coherence [1989], 5) by J.J.C. Smart - Explanation - Opening Address p.04 | |
| A reaction: This has to be a minimal axiom for coherence, but coherence is always taken to be more than mere logical consistency. Mutual relevance is the first step. At least there must be no category mistakes. |
| 17069 | 6: A proposition's acceptability depends on its coherence with a system [Thagard, by Smart] |
| Full Idea: 6: Acceptability of a proposition in a system depends on its coherence with the propositions in that system. | |
| From: report of Paul Thagard (Explanatory Coherence [1989], 6) by J.J.C. Smart - Explanation - Opening Address p.04 | |
| A reaction: Thagard tried to build an AI system for coherent explanations, but I would say he has no chance with these six axioms, because they never grasp the nettle of what 'coherence' means. You first need rules for how things relate. What things are comparable? |
| 17599 | The best theory has the highest subjective (Bayesian) probability? [Thagard] |
| Full Idea: On the Bayesian view, the best theory is the one with the highest subjective probability, given the evidence as calculated by Bayes's theorem. | |
| From: Paul Thagard (Coherence: The Price is Right [2012], p.45) |
| 1457 | Morality requires a minimum commitment to the self [Rashdall] |
| Full Idea: A bare minimum of metaphysical belief about the self is found to be absolutely presupposed in the very idea of morality. | |
| From: Hastings Rashdall (Theory of Good and Evil [1907], II.III.I.4) | |
| A reaction: This may not be true of virtue theory, where we could have a whole creature which lacked any sense of personhood, but yet had clear virtues and vices in its social functioning. Even if choices are central to morality, that might not need a self. |
| 6674 | All moral judgements ultimately concern the value of ends [Rashdall] |
| Full Idea: All moral judgements are ultimately judgements as to the value of ends. | |
| From: Hastings Rashdall (Theory of Good and Evil [1907], VII.I) | |
| A reaction: I am increasingly struck by this, especially when observing that it is the great gap in Kant's theory. For some odd reason, he gives being rational the highest possible value. Why? Nietzsche is good on this. 'Eudaimonia' seems a good start, to me. |
| 6673 | Ideal Utilitarianism is teleological but non-hedonistic; the aim is an ideal end, which includes pleasure [Rashdall] |
| Full Idea: My view, called Ideal Utilitarianism, combines the utilitarian principle that Ethics must be teleological with a non-hedonistic view of ethical ends; actions are right or wrong as they produce an ideal end, which includes, but is not limited to, pleasure. | |
| From: Hastings Rashdall (Theory of Good and Evil [1907], VII.I) | |
| A reaction: I certainly think that if you are going to be a consequentialist, then it is ridiculous to limit the end to pleasure, as it is an 'open question' as to whether we judge pleasures or pains to be good or bad. I am fond of beauty, goodness and truth, myself. |
| 20086 | Nowadays sovereignty (once the basis of a state) has become relative [Reybrouck] |
| Full Idea: In the twenty-first century, sovereignty, once the basis of the nation state, has become a relative concept. ...Powerlessness is the key word of our time. | |
| From: David van Reybrouck (Against Elections [2013], 1 'Crisis') | |
| A reaction: The point is that nation states now have limited power, in the face of larger unions, multinational companies, and global problems. |
| 20090 | Today it seems almost impossible to learn the will of the people [Reybrouck] |
| Full Idea: Imagine having to develop a system today that would express the will of the people. | |
| From: David van Reybrouck (Against Elections [2013], 2 'electoral') | |
| A reaction: Our recent Brexit referendum didn't do the job, because it was confined to a single question. Van Reybrouck laughs at the idea of expressing it through a polling both. How about a council of 500, drawn by lots? Meet for three months. |
| 20087 | There are no united monolothic 'peoples', and no 'national gut feelings' [Reybrouck] |
| Full Idea: There is no such thing as one monolithic 'people' (every society has its diversity), nor is there anything that could be described as a 'national gut feeling'. | |
| From: David van Reybrouck (Against Elections [2013], 2 'populism') | |
| A reaction: Rousseau yearned for a republic no bigger than Geneva. I don't see why we should give up on the general will in huge modern societies. It is likely, though, to be an anodyne lowest common denominator. No bad thing, perhaps. |
| 20089 | Technocrats may be efficient, but they lose legitimacy as soon as they do unpopular things [Reybrouck] |
| Full Idea: Efficiency does not automatically generate legitimacy, and faith in the technocrat melts away as soon as spending cuts are implemented. | |
| From: David van Reybrouck (Against Elections [2013], 2 'democracy') | |
| A reaction: They can hang on to legitimacy if they can come up with some technical mumbo-jumbo like 'monetarism' which the people will swallow. |
| 20088 | Technocrats are expert managers, who replace politicians, and can be long-term and unpopular [Reybrouck] |
| Full Idea: Technocracy is a system where experts are charged with looking after the public interest. ...Technocrats are managers who replace politicians, so they can concentrate on long-term solutions and announce unpopular measures. | |
| From: David van Reybrouck (Against Elections [2013], 2 'technocracy') | |
| A reaction: I like technocrats. They just need to be accountable. In the UK we have far more respect for the governor of the Bank of England than for any politician. |
| 20085 | Democracy is the best compromise between legitimacy and efficiency [Reybrouck] |
| Full Idea: Democracy is the least bad form of all governments precisely because it attempts to find a healthy balance between legitimacy and efficiency. | |
| From: David van Reybrouck (Against Elections [2013], 1 'Crisis') | |
| A reaction: There seems to be a widespread feeling that democracy is declining in efficiency, and that may be because our remoteness from government decreases legitimacy, so we have less commitment to getting things done. |
| 20095 | A referendum result arises largely from ignorance [Reybrouck] |
| Full Idea: In a referendum you ask everyone to vote on a subject that usually only a few know anything about. | |
| From: David van Reybrouck (Against Elections [2013], 4 'remedies') | |
| A reaction: Tell me about it! I was forced to vote in the 2016 Brexit referendum, and felt thoroughly out of my depth on such a complex economic question. |
| 20094 | You don't really govern people if you don't involve them [Reybrouck] |
| Full Idea: Even with the best of intentions, those who govern the people without involving them, govern them only in a limited sense. | |
| From: David van Reybrouck (Against Elections [2013], 4 intro) | |
| A reaction: But if they are highly involved, who is governing who? Do we want the people to become happier about being governed, or do we want them more involved in doing the governing? |
| 20093 | In the 18th century democratic lots lost out to elections, that gave us a non-hereditary aristocracy [Reybrouck] |
| Full Idea: The drawing of lots, the most democratic of all political instruments, lost out in the eighteenth century to elections, a procedure that was not invented as a democratic instrument, but as a means of bringing a new non-hereditary aristocracy to power. | |
| From: David van Reybrouck (Against Elections [2013], 3 'democratisation') | |
| A reaction: This is the basic thesis of Van Reybrouck's book. He argues for the extensive use of lots ('sortition') for getting people involved in modern democracies. I love the idea that in a good democracy you get an occasional chance to rule. |
| 20091 | Representative elections were developed in order to avoid democracy [Reybrouck] |
| Full Idea: Bernard Manin (1995) revealed how, immediately after the American and French revolutions, the electoral-representative system was chosen with the intention of keeping at bay the tumult of democracy. | |
| From: David van Reybrouck (Against Elections [2013], 3 'procedure') | |
| A reaction: At the time America and France were two of the largest countries in the world, and communication and transport were slow. That has changed. |
| 1458 | Conduct is only reasonable or unreasonable if the world is governed by reason [Rashdall] |
| Full Idea: Absolutely reasonable or unreasonable conduct could not exist in a world which was not itself the product of reason or governed by its dictates. | |
| From: Hastings Rashdall (Theory of Good and Evil [1907], II.III.I.4) |
| 1459 | Absolute moral ideals can't exist in human minds or material things, so their acceptance implies a greater Mind [Rashdall, by PG] |
| Full Idea: An absolute moral ideal cannot exist in material things, or in the minds of individual people, so belief in it requires belief in a Mind which contains the ideal and is its source. | |
| From: report of Hastings Rashdall (Theory of Good and Evil [1907], II.III.I.4) by PG - Db (ideas) |
