7278 | Words of wisdom are precise and clear [Zhuangzi (Chuang Tzu)] |
Full Idea: Words of wisdom are precise and clear. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.2) | |
A reaction: I can only approve of this. The issue of clarity is much discussed amongs philosophers, especially in the analytic v continental debate. Note, therefore, the additional requirement to be 'precise'. Should we be less clear in order to be precise? |
23350 | A wise philosophers uses reason to cautiously judge each aspect of living [Epictetus] |
Full Idea: The sinews of a philosopher are desire that never fails in its achievement; aversion that never meets with what it would avoid; appropriate impulse; carefully considered purpose; and assent that is never precipitate. | |
From: Epictetus (The Discourses [c.56], 2.08.29) | |
A reaction: This is a very individual view of wisdom and the philosopher, whereas wisdom is often thought to have a social role. Is it not important for a philosopher to at least offer advice? |
23355 | The task of philosophy is to establish standards, as occurs with weights and measures [Epictetus] |
Full Idea: Things are judged and weighed, when we have the standards ready. This is the task of philosophy: to examine and establish the standards. | |
From: Epictetus (The Discourses [c.56], 2.11.24) | |
A reaction: It is interesting that this gives philosophers a very specific social role, and also that it seems to identify epistemology as First Philosophy. Other disciplines, of course, establish their own standards without reference to philosophy. |
21394 | Philosophy is knowing each logos, how they fit together, and what follows from them [Epictetus] |
Full Idea: [Philosophical speculation] consists in knowing the elements of 'logos', what each of them is like, how they fit together, and what follows from them. | |
From: Epictetus (The Discourses [c.56], 4.08.14), quoted by A.A. Long - Hellenistic Philosophy 4.1 | |
A reaction: [Said to echo Zeno] If you substitute understanding for 'logos' (plausibly), I think this is exactly the view of philosophy I would subscribe to. We want to understand each aspect of life, and we want those understandings to cohere with one another. |
20876 | Philosophy investigates the causes of disagreements, and seeks a standard for settling them [Epictetus] |
Full Idea: The start of philosophy is perception of the mutual conflict among people, and a search for its cause, plus the rejection and distrust of mere opinion, an investigation to see if opinion is right, and the discovery of some canon, like scales for weighing. | |
From: Epictetus (The Discourses [c.56], 2.11.13) | |
A reaction: So the number one aim of philosophy is epistemological, to find the criterion for true opinion. But it starts in real life, and would cease to trade if people would just agree. I think we should set the bar higher than that. |
7281 | Don't even start, let's just stay put [Zhuangzi (Chuang Tzu)] |
Full Idea: Don't even start, let's just stay put. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.2) | |
A reaction: What a remarkable proposal! He seems frightened to make an omelette, because he will have to break an egg, or he might burn himself. I can't relate to this idea, but it's existence must be noted, like other scepticisms. |
23344 | Reason itself must be compounded from some of our impressions [Epictetus] |
Full Idea: What is reason itself? Something compounded from impressions of a certain kind. | |
From: Epictetus (The Discourses [c.56], 1.20.05) | |
A reaction: This seems to be the only escape from the dead end attempts to rationally justify reason. Making reason a primitive absolute is crazy metaphysics. |
23343 | Because reason performs all analysis, we should analyse reason - but how? [Epictetus] |
Full Idea: Since it is reason that analyses and completes all other things, reason itself should not be left unanalysed. But by what shall it be analysed? ..That is why philosophers put logic first, just as when measuring grain we first examine the measure. | |
From: Epictetus (The Discourses [c.56], 1.17.01) | |
A reaction: The problem of the definitive metre rule in Paris. I say we have to test reason against the physical world, and the measure of reason is truth. Something has to be primitive, but reason is too vague for that role. Idea 23344 agrees with me! |
7282 | Disagreement means you do not understand at all [Zhuangzi (Chuang Tzu)] |
Full Idea: The sage encompasses everything, while ordinary people just argue about things. Disagreement means you do not understand at all. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.2) | |
A reaction: This is why democracy and western analytical philosophy come as a package. We can't assume that our government is always right, and we can't assume that a 'sage' has managed to encompass everything. Criticism is essential! |
7284 | If you beat me in argument, does that mean you are right? [Zhuangzi (Chuang Tzu)] |
Full Idea: If you get the better of me in a disagreement, rather than me getting the better of you, does this mean that you are automatically right and I am automatically wrong? | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.2) | |
A reaction: Very nice. I don't, though, think that this invalidates the process of argument. What matters about such an exchange is the resulting reflection by the two parties. Only a fool thinks that he is right because he won, or wrong because he lost. |
7289 | Do not try to do things, or to master knowledge; just be empty [Zhuangzi (Chuang Tzu)] |
Full Idea: Do not try to do things. Do not try to master knowledge. ...Just be empty. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.7) | |
A reaction: Stands as a nice challenge to the assumption that knowledge is a good thing. Aristotle's views make a nice contrast (Ideas 548 and 549). Personally I totally agree with Aristotle, and with the western tradition. |
23359 | We can't believe apparent falsehoods, or deny apparent truths [Epictetus] |
Full Idea: It is impossible to assent to an apparent falsehood, or to deny an apparent truth. | |
From: Epictetus (The Discourses [c.56], 3.07.15) | |
A reaction: The way some philosophers write you would think that most beliefs just result from private whims or social fashion. That happens, of course, but most beliefs result from direct contact with reality. |
23356 | Self-evidence is most obvious when people who deny a proposition still have to use it [Epictetus] |
Full Idea: It is about the strongest proof one could offer of a proposition being evident, that even he who contradicts it finds himself having to make use of it. | |
From: Epictetus (The Discourses [c.56], 2.20.01) | |
A reaction: Philosophers sometimes make fools of themselves by trying, by the use of elaborate sophistry, to demolish propositions which are self-evidently true. Don't be one of these philosophers! |
23403 | You know you were dreaming when you wake, but there might then be a greater awakening from that [Zhuangzi (Chuang Tzu)] |
Full Idea: Often after waking do you know that your dream was a dream. Still, there may be an even greater awakening after which you will know that this, too, was just a greater dream. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], 02), quoted by Bryan van Norden - Intro to Classical Chinese Philosophy 9.2 | |
A reaction: This is the key to the full horror of dream scepticism (as dramatised in the film 'The Matrix'). We can never know whether there is yet another awakening about to occur. |
7285 | Did Chuang Tzu dream he was a butterfly, or a butterfly dream he was Chuang Tzu? [Zhuangzi (Chuang Tzu)] |
Full Idea: Once I, Chuang Tzu, dreamt that I was a butterfly, flitting around and enjoying myself. Suddenly I woke and was Chuang Tzu again. But had I been Chuang Tzu dreaming I was a butterfly, or a butterfly dreaming I was now Chuang Tzu? | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.2) | |
A reaction: Plato (Idea 2047) also spotted this problem, later made famous by Descartes (Idea 2250). Given the size of a butterfly's brain, this suggests that Chuang Tzu was a dualist. What can't I take the idea seriously, when reason says I should? |
7621 | Special relativity, unlike general relativity, was operationalist in spirit [Putnam on Einstein] |
Full Idea: Einstein's interpretation of special relativity was operationalist in spirit (in marked contrast to the interpretation he gave to general relativity). | |
From: comment on Albert Einstein (works [1915]) by Hilary Putnam - Reason, Truth and History Ch.5 | |
A reaction: The late twentieth century was polluted with daft relativism, and I hold Einstein partly responsible, suspecting that he was a bad philosopher. The later development of Einstein's view noted here is interesting. |
7277 | The perfect man has no self [Zhuangzi (Chuang Tzu)] |
Full Idea: As the saying goes, 'The perfect man has no self' | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.1) | |
A reaction: This seems to be quoted with approval. This is interesting because it implies that lesser beings do have a self, and that having a self is a moral issue, and one which can be controlled. One could, I suppose, concentrate on externals. |
7286 | To see with true clarity, your self must be irrelevant [Zhuangzi (Chuang Tzu)] |
Full Idea: When a man discerns his own self as irrelevant, he sees with true clarity. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.6) | |
A reaction: Seeing 'with clarity' is only one of the ways of seeing, and one mustn't unquestioningly assume that it is the best. Wisdom should contemplate vision with and without the self, and then rise higher and compare the two views. Compare Parfit (Idea 5518). |
23329 | We make progress when we improve and naturalise our choices, asserting their freedom [Epictetus] |
Full Idea: Progress is when any of you turns to his own faculty of choice, working at it and perfecting it, so as to bring it fully into harmony with nature; elevated, free, unrestrained, unhindered, faithful, self-respecting. | |
From: Epictetus (The Discourses [c.56], 1.04.18) | |
A reaction: [See also Disc.3.5.7] Rationality is the stoic concept of being in 'harmony with nature'. It appears (from reading Frede) that this may be the FIRST EVER reference to free will. Note the very rhetorical way in which it is presented. |
23330 | Freedom is making all things happen by choice, without constraint [Epictetus] |
Full Idea: He is free for whom all things happen in accordance with his choice, and whom no one can constrain. | |
From: Epictetus (The Discourses [c.56], 1.12.09) | |
A reaction: The idea of 'free' will seems to have resulted from a wide extension of the idea of constraint, with global determinism lurking in the background. |
23342 | Freedom is acting by choice, with no constraint possible [Epictetus] |
Full Idea: He is free for whom all things happen in accordance with his choice, and whom no one can constrain. | |
From: Epictetus (The Discourses [c.56], 1.12.09) | |
A reaction: Presumable this means that constraint is absolutely impossible, even by Zeus, and not just contingent possibility, when no one sees me raid the fridge. |
23332 | Zeus gave me a nature which is free (like himself) from all compulsion [Epictetus] |
Full Idea: Zeus placed my good nature in my own power, and gave it to me as he has it himself, free from all hindrance, compulsion and restraint. | |
From: Epictetus (The Discourses [c.56], 3.03.10) | |
A reaction: Although Frede traces the origin of free will to the centrality of choice in moral life (and hence to the elevation of its importance), this remark shows that there is a religious aspect to it. Zeus is supreme, and obviously has free will. |
23331 | Not even Zeus can control what I choose [Epictetus] |
Full Idea: You can fetter my leg, but not even Zeus himself can get the better of my choice. | |
From: Epictetus (The Discourses [c.56], 1.01.23) | |
A reaction: This is the beginnings of the idea of free will. It is based on the accurate observation that the intrinsic privacy of a mind means that no external force can be assured of controlling its actions. Epictetus failed to think of internal forces. |
23338 | You can fetter my leg, but not even Zeus can control my power of choice [Epictetus] |
Full Idea: What are you saying, man? Fetter me? You will fetter my leg; but not even Zeus himself can get the better of my choice. | |
From: Epictetus (The Discourses [c.56], 1.01.23) | |
A reaction: This seems to be the beginning of the idea of 'absolute' freedom, which is conjured up to preserve perfect inegrity and complete responsibility. Obviously you can be prevented from doing what you choose, so this is not compatibilism. |
20875 | If we could foresee the future, we should collaborate with disease and death [Epictetus] |
Full Idea: The philosophers are right to say that if the honorable and good person knew what was going to happen, he would even collaborate with disease, death and lameness. | |
From: Epictetus (The Discourses [c.56], 2.10.05) | |
A reaction: The 'philosophers' must be the earlier stoics, founders of his school. |
23347 | If I know I am fated to be ill, I should want to be ill [Epictetus] |
Full Idea: If I really knew that it was ordained for me to be ill at this moment, I would aspire to be so. | |
From: Epictetus (The Discourses [c.56], 2.06.10) | |
A reaction: The rub, of course, is that it is presumably impossible to know what is fated. Book 2.7 is on divination. I don't see any good in a mortally ill person desiring, for that reason alone, to die. Rage against the dying of the light, I say. |
7279 | If words can't be defined, they may just be the chirruping of chicks [Zhuangzi (Chuang Tzu)] |
Full Idea: Our words are not just hot air. Words work because they are something, but the problem is that, if we cannot define a word's meaning, it doesn't really say anything. Can we make a case for it being anything different from the chirruping of chicks? | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.2) | |
A reaction: This obviously points us towards Quine's challenge to analyticity, and hence the value of definitions (Ideas 1622 and 1624). Even for Chuang Tzu, it seems naïve to think that you cannot use a word well if you cannot define it. |
23404 | Words are for meaning, and once you have that you can forget the words [Zhuangzi (Chuang Tzu)] |
Full Idea: Words are for meaning: when you've gotten the meaning, you can forget the words. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], 26), quoted by Bryan van Norden - Intro to Classical Chinese Philosophy 9.VI | |
A reaction: 'What exactly did this person say?' 'Don't know, but I've given you the accurate gist'. This is such an obvious phenomenon that I amazed by modern philosophers who deny propositions, or deny meaning entirely. |
23325 | Epictetus developed a notion of will as the source of our responsibility [Epictetus, by Frede,M] |
Full Idea: The notion of will in Epictetus is clearly developed to pinpoint the source of our responsibility for our actions and to identify precisely what it is that makes them our own doings. | |
From: report of Epictetus (The Discourses [c.56]) by Michael Frede - A Free Will 3 | |
A reaction: So the key move is that responsibility needs a 'source', rather than being a generalisation about how our actions arise. The next step is demand an 'ultimate' source, and this leads to the idea that this new will is 'free'. This will can be good or bad. |
20873 | Tragedies are versified sufferings of people impressed by externals [Epictetus] |
Full Idea: Tragedies are nothing but the sufferings of people who are impressed by externals, performed in the right sort of meter. | |
From: Epictetus (The Discourses [c.56], 1.04.26) | |
A reaction: The externals are things like honour, position and wealth. Wonderfully dismissive! |
23364 | Homer wrote to show that the most blessed men can be ruined by poor judgement [Epictetus] |
Full Idea: Did not Homer write to show us that the noblest, the strongest, the richest, the handsomest of men may nevertheless be the most unfortunate and wretched, if they do not hold the judgements that they ought to hold? | |
From: Epictetus (The Discourses [c.56], 4.10.36) | |
A reaction: This seems to be right. He clearly wrote about the greatest and most memorable events of recent times, but not just to record triumphs, because almost every hero (in the Iliad, at least) ends in disaster. |
23340 | We consist of animal bodies and god-like reason [Epictetus] |
Full Idea: We have these two elements mingled within us, a body in common with the animals, and reason and intelligence in common with the gods. | |
From: Epictetus (The Discourses [c.56], 1.03.03) | |
A reaction: This is what I call Human Exceptionalism, but note that it doesn't invoke a Christian soul or spiritual aspect. This separation of reason goes back at least to Plato. High time we stopped thinking this way. Animals behave very sensibly. |
23358 | Every species produces exceptional beings, and we must just accept their nature [Epictetus] |
Full Idea: In every species nature produces some exceptional being, in oxen, in dogs, in bees, in horses. We do not say to them 'Who are you?' It will tell you 'I am like the purple in the robe. Do not expect me to be like the rest, or find fault with my nature'. | |
From: Epictetus (The Discourses [c.56], 3.01.23) | |
A reaction: This idea began with Aristotle's 'great soul', and presumably culminates in Nietzsche, who fills in more detail. In the modern world such people are mostly nothing but trouble. |
23339 | I will die as becomes a person returning what he does not own [Epictetus] |
Full Idea: When the time comes, then I will die - as becomes a person who gives back what is not his own. | |
From: Epictetus (The Discourses [c.56], 1.01.32) | |
A reaction: There is a tension between his demand that he have full control of his choices, and this humility that says his actual life is not his own. The things which can't be controlled, though, are 'indifferents' so life and death are indifferent. |
23345 | Don't be frightened of pain or death; only be frightened of fearing them [Epictetus] |
Full Idea: It is not pain or death that is to be feared, but the fear of pain or death. | |
From: Epictetus (The Discourses [c.56], 2.01.13) | |
A reaction: These two cases are quite different, I would say. I'm much more frightened of pain than I am of the fear of pain, and the opposite view seems absurd. About death, though, I think this is right. Mostly I'm with Spinoza: think about life, not death. |
23357 | Knowledge of what is good leads to love; only the wise, who distinguish good from evil, can love [Epictetus] |
Full Idea: Whoever has knowledge of good things would know how to love them; and how could he who cannot distinguish good things from evil still have to power to love? It follows that the wise man alone has the power to love. | |
From: Epictetus (The Discourses [c.56], 2.22.03) | |
A reaction: A rather heartwarming remark, but hard to assess for its truth. Evil people are unable to love? Not even love a cat, or their favourite car? We would never call someone wise if they lacked love. |
23363 | The evil for everything is what is contrary to its nature [Epictetus] |
Full Idea: Where is the paradox if we say that what is evil for everything is what is contrary to its nature? | |
From: Epictetus (The Discourses [c.56], 4.01.125) | |
A reaction: A very Greek view. For humans, it must rely on the belief that human nature is essentially good. If I am sometimes grumpy and annoying, why is that not part of my nature? |
23328 | The essences of good and evil are in dispositions to choose [Epictetus] |
Full Idea: The essence of the good is a certain disposition of our choice, and essence of evil likewise. | |
From: Epictetus (The Discourses [c.56], 1.29.01) | |
A reaction: This is the origin of Kant's famous view, that the only true good is a good will. This is the alternative to good character or good states of affairs as the good. It points towards the modern more legalistic view of morality, as concerning actions. |
23362 | All human ills result from failure to apply preconceptions to particular cases [Epictetus] |
Full Idea: The cause of all human ills is that people are incapable of applying their general preconceptions to particular cases. | |
From: Epictetus (The Discourses [c.56], 4.01.42) | |
A reaction: I'm not sure whether 'preconceptions' is meant pejoratively (as unthinking, and opposed to true principles). This sounds like modern particularism (e.g. Jonathan Dancy) to the letter. |
23353 | We have a natural sense of honour [Epictetus] |
Full Idea: What faculty do you mean? - Have we not a natural sense of honour? - We have. | |
From: Epictetus (The Discourses [c.56], 2.10.22) | |
A reaction: This seems unlikely, given the lower status that honour now has with us, compared to two hundred years ago. But there may be a natural sense of status, and of humiliation and shame. |
23354 | If someone harms themselves in harming me, then I harm myself by returning the harm [Epictetus] |
Full Idea: Since he has harmed himself by wronging me, shall not I harm myself by harming him? | |
From: Epictetus (The Discourses [c.56], 2.10.26) | |
A reaction: I am very keen on this idea. See Hamlet's remarks to Polonius about 'honour and dignity'. The best strategy for achieving moral excellence is to focus on our own characters, rather than how to act, and to respond to others. |
23324 | In the Discourses choice [prohairesis] defines our character and behaviour [Epictetus, by Frede,M] |
Full Idea: In Epictetus's 'Discourses' the notion of choice [prohairesis] plays perhaps the central role. It is our prohairesis which defines us a person, as the sort of person we are; it is our prohairesis which determines how we behave. | |
From: report of Epictetus (The Discourses [c.56]) by Michael Frede - A Free Will 3 | |
A reaction: Frede is charting the gradual move in Greek philosophy from action by desire, reason and habit to action by the will (which then turns out to be 'free'). Character started as dispositions and ended as choices. |
7283 | Great courage is not violent [Zhuangzi (Chuang Tzu)] |
Full Idea: Great courage is not violent. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.2) | |
A reaction: A very nice remark. This, I think, is what the Greeks were struggling to say about courage, but they never quite pinned it down as Chuang Tzu does. |
23361 | Health is only a good when it is used well [Epictetus] |
Full Idea: Is health a good and sickness an evil? No. Health is good when used well, and bad when used ill. | |
From: Epictetus (The Discourses [c.56], 3.20.04) | |
A reaction: Although I like the idea that health is a natural value, which bridges the gap from facts to values (as a successful function), there is no denying that the health of very evil people is not something the rest of us hope for. |
23346 | A person is as naturally a part of a city as a foot is part of the body [Epictetus] |
Full Idea: Just as the foot in detachment is no longer a foot, so you in detachment are not longer a man. For what is a man? A part of a city, first. | |
From: Epictetus (The Discourses [c.56], 2.05.26) | |
A reaction: It is, of course, not true that a detached foot ceases to be a foot (and an isolated human is still a human). This an extreme version of the Aristotelian idea that we are essentially social. It is, though, the sort of view favoured by totalitarianism. |
23351 | We are citizens of the universe, and principal parts of it [Epictetus] |
Full Idea: You are a citizen of the universe, and a part of it; and no subservient, but a principal part of it. | |
From: Epictetus (The Discourses [c.56], 2.10.03) | |
A reaction: He got this view from Diogenes of Sinope, one of his heroes. What community you are a part of seems to be a choice as much as a fact. Am I British or a European? |
20874 | A citizen is committed to ignore private advantage, and seek communal good [Epictetus] |
Full Idea: The commitment of the citizen is to have no private advantage, not to deliberate about anything as though one were a separate part. | |
From: Epictetus (The Discourses [c.56], 2.10.04) | |
A reaction: This is the modern problem of whether democratic voters are choosing for themselves or for the community. I think we should make an active effort at every election to persuade voters to aim for the communal good. Cf Rawls. |
23352 | A citizen should only consider what is good for the whole society [Epictetus] |
Full Idea: The calling of a citizen is to consider nothing in terms of personal advantage, never to deliberate on anything as though detached from the whole, but be like our hand or foot. | |
From: Epictetus (The Discourses [c.56], 2.10.04) | |
A reaction: Fat chance of that in an aggressively capitalist society. I've always voted for what I thought was the common good, and was shocked to gradually realise that many people only vote for what promotes their own interests. Heigh ho. |
22604 | Punishing a criminal for moral ignorance is the same as punishing someone for being blind [Epictetus] |
Full Idea: You should ask 'Ought not this man to be put to death, who is deceived in things of the greatest importance, and is blinded in distinguishing good from evil?' …You then see how inhuman it is, and the same as 'Ought not this blind man to be put to death?' | |
From: Epictetus (The Discourses [c.56], 1.18.6-7) | |
A reaction: This is the doctrine of Socrates, that evil is ignorance (and weakness of will [akrasia] is impossible). Epictetus wants us to reason with the man, but what should be do if reasoning fails and he persists in his crimes? |
23349 | Asses are born to carry human burdens, not as ends in themselves [Epictetus] |
Full Idea: An ass is surely not born as an end in itself? No, but because we had need of a back that is able to carry burdens. | |
From: Epictetus (The Discourses [c.56], 2.08.07) | |
A reaction: This is the absurd human exceptionalism which plagues our thinking. It would be somewhat true of animals which are specifically bred for human work, such as large cart horses. |
22955 | Einstein took causation to be the bedrock of physics [Einstein, by Coveney/Highfield] |
Full Idea: It is difficult to overplay Einstein's commitment to the concept of causality as the bedrock of physics. | |
From: report of Albert Einstein (works [1915]) by P Coveney / R Highfield - The Arrow of Time 3 'problem' | |
A reaction: I normally avoid arguments from authority, but this carries a bit of weight (e.g. when Russell tries to oppose it). What happens to Einstein's theories if you remove causation from them? |
20638 | General relativity assumes laws of nature are the same in all frames of reference [Einstein, by Close] |
Full Idea: Einstein came to general relativity from the principles that the laws of nature are the same in all frames of reference. | |
From: report of Albert Einstein (works [1915]) by Frank Close - Theories of Everything 5 'Cosmological' | |
A reaction: I wish physicists would tell us a bit more about the ontological status of the 'laws of nature'. Presumably they are not supernatural, so there is an aspect of nature which is constant in all frames of reference. Explanation please. |
20636 | Newton is a special case of Einstein's general theory, with an infinite speed of light [Einstein, by Close] |
Full Idea: Einstein's general relativity included Newton's theory as a special case: Newton's theory corresponds to the speed of light being infinite relative to the speed of the interacting bodies. | |
From: report of Albert Einstein (works [1915]) by Frank Close - Theories of Everything 5 'Gravity' | |
A reaction: So Newton's theory was NOT wrong, but he made the false assumption that the speed of light was infinite. |
21230 | The theory is 'special' because it sticks to observers moving straight, at constant speeds [Einstein, by Farmelo] |
Full Idea: Einstein's first theory is 'special' because it only deals with observers who move in a straight line at constant speeds with respect to one another. | |
From: report of Albert Einstein (works [1915]) by Graham Farmelo - The Strangest Man 03 | |
A reaction: Most theories of this period seem to have focused on the simplest cases, for obvious reasons. |
21231 | Assume the speed of light is constant for all observers, and the laws of physics are the same [Einstein, by Farmelo] |
Full Idea: Einstein assumed that when each observer measures the speed of light in a vacuum, they find the same value, regardless of their speed; and that measurements will lead to agreement on the laws of physics. | |
From: report of Albert Einstein (works [1915]) by Graham Farmelo - The Strangest Man 03 | |
A reaction: So are the laws of physics constant for all observers, irrespective of their speed? |
20634 | General Relativity says there is no absolute force or acceleration [Einstein, by Close] |
Full Idea: Einstein's General Theory arose from the idea that there is no absolute measure of force and acceleration. | |
From: report of Albert Einstein (works [1915]) by Frank Close - Theories of Everything 5 'Gravity' | |
A reaction: If absolutely everything is only true relative to something else you wonder what the point of measuring anything is. How big can a 'frame of reference' or 'inertial frame' be. Is the multiverse a frame of reference? |
20648 | Mass is a measure of energy content [Einstein] |
Full Idea: The mass of a body is the measure of its energy content. | |
From: Albert Einstein (works [1915]), quoted by Peter Watson - Convergence 04 'Intro' | |
A reaction: If I knew what energy was, this would be very illuminating. This idea is e=mc^2 in words. We now have the Higgs field to consider when trying to understand mass. |
21232 | Space-time arises from the connection between measurements of space and of time [Einstein, by Farmelo] |
Full Idea: Einstein noted that the measurements of space and time are not independent but inextricably linked, leading to the idea of unified space-time (introduced by his former teacher Minkowski). | |
From: report of Albert Einstein (works [1915]) by Graham Farmelo - The Strangest Man 03 | |
A reaction: Notice the instrumentalist assumptions behind this. |
7280 | As all life is one, what need is there for words? [Zhuangzi (Chuang Tzu)] |
Full Idea: As all life is one, what need is there for words? | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.2) | |
A reaction: In a sense this is nonsense, but it has an appeal. I presume that God would not need words, any more than he would need arithmetic. Life is obviously a complex one, with parts which can be discussed. |
23341 | God created humans as spectators and interpreters of God's works [Epictetus] |
Full Idea: God has introduced man into the world as a spectator of himself and of his works: and not only as a spectator of them, but an interpreter of them as well. | |
From: Epictetus (The Discourses [c.56], 1.06.19) | |
A reaction: This idea (which strikes me as bizarre) was picked up directly by the Christians. I can't imagine every Johnson wanting to creating their own Boswell. If you think we are divinely created, you have to propose some motive for it, I suppose. |
23348 | Both god and the good bring benefits, so their true nature seems to be the same [Epictetus] |
Full Idea: God brings benefits; but the good also brings benefit. It would seem, then, that where the true nature of god is, there too is the true nature of good. | |
From: Epictetus (The Discourses [c.56], 2.08.01) | |
A reaction: An enthymeme, missing the premise that there can only be one source of benefit (which sounds unlikely). Does god bring anything other than benefits? And does the good? I think this is an idea from later platonism. |
7626 | I do not believe in a personal God [Einstein] |
Full Idea: I do not believe in a personal God and I have never denied this but have expressed it clearly. | |
From: Albert Einstein (works [1915]), quoted by Richard Dawkins - The God Delusion Ch.1.15 | |
A reaction: This is an important corrective to those who claim Einstein as religious, on the basis of remarks about God not playing dice etc. See the whole of Dawkins's chapter on Einstein for full discussion. |
7288 | Go with the flow, and be one with the void of Heaven [Zhuangzi (Chuang Tzu)] |
Full Idea: Don't struggle, go with the flow, and you will find yourself at one with the vastness of the void of Heaven. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.6) | |
A reaction: Ugh. I've got all eternity to do that. The underlying assumption of Taoism seems to be that it is better not to have been born, and if you are thus unfortunate, you should try to pretend that it never happened. Much too negative for my taste. |
7287 | Fish forget about each other in the pond and forget each other in the Tao [Zhuangzi (Chuang Tzu)] |
Full Idea: Fish forget about each other in the pond and forget each other in the Tao. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.6) | |
A reaction: Strikingly different from Christianity. No wonder Europeans used to describe orientals as 'enigmatic'; the faces of Taoists presumably express indifference. Not for me, I'm afraid. I identify with my fellow humans, because of our shared predicaments. |
23360 | Each of the four elements in you is entirely scattered after death [Epictetus] |
Full Idea: Whatever was in you of fire, departs into fire; what was of earth, into earth; what of air, into air; what of water, into water. There is no Hades, nor Acheron. | |
From: Epictetus (The Discourses [c.56], 3.13.15) | |
A reaction: This sort of remark may explain why so few of the great Stoic texts (such as those of Chrysippus) survived the Christian era. |
