| 8014 | Resolve a complex into simple elements, then reconstruct the complex by using them [Hobbes, by MacIntyre] |
| Full Idea: Hobbes took his method from Galileo, of resolving any complex situation into its logically primitive, simple elements and then using the simple elements to show how the complex situation could be reconstructed. | |
| From: report of Thomas Hobbes (Leviathan [1651]) by Alasdair MacIntyre - A Short History of Ethics Ch.10 | |
| A reaction: Reverse engineering of reality. This idea, wherever it comes from, strikes me as the key to the advance of human understanding. No one has yet improved on it as a method, in science or philosophy. Reconstruction needs the mechanism. |
| 7559 | Every part of the universe is body, and non-body is not part of it [Hobbes] |
| Full Idea: The world is corporeal, that is to say, body...and every part of the universe is body, and that which is not body is no part of the universe. | |
| From: Thomas Hobbes (Leviathan [1651], IV.46) | |
| A reaction: [Hobbes concedes existence to visible spirits, but not invisible ones]. This is the kind of remark which got Hobbes hated. It is also the sort of thing that makes him the best candidate for the 'first modern man'. |
| 2356 | Appearance and reality can be separated by mirrors and echoes [Hobbes] |
| Full Idea: If colours or sounds were in the bodies or objects that cause them, they could not be severed from them, as by glasses, and in echoes by reflection, we see they are; where we know the thing we see is in one place, the appearance in another. | |
| From: Thomas Hobbes (Leviathan [1651], 1.01) |
| 2357 | Dreams must be false because they seem absurd, but dreams don't see waking as absurd [Hobbes] |
| Full Idea: Because waking I often observe the absurdity of dreams, but never dream of the absurdity of my waking thoughts, I am well satisfied that, being awake, I know I dream not, though when I dream I think myself awake. | |
| From: Thomas Hobbes (Leviathan [1651], 1.02) |
| 4608 | Minds are hard-wired, or trial-and-error, or experimental, or full self-aware [Dennett, by Heil] |
| Full Idea: Dennett identifies a hierarchy of minds running from 'Darwinian' (hard-wired solutions to problems), to 'Skinnerian' (trial-and-error), to 'Popperian' (anticipating possible experience), to 'Gregorian' (self-conscious representation, probably linguistic). | |
| From: report of Daniel C. Dennett (Kinds of Minds [1996]) by John Heil - Philosophy of Mind Ch.5 | |
| A reaction: Interesting. The concept of an experiment seems a major step (assessing reality against an internal map), and the ability to think about one's own thoughts certainly strikes me as the mark of a top level mind. Maybe that is the importance of language. |
| 4880 | Sentience comes in grades from robotic to super-human; we only draw a line for moral reasons [Dennett] |
| Full Idea: 'Sentience' comes in every imaginable grade or intensity, from the simplest and most 'robotic', to the most exquisitely sensitive, hyper-reactive 'human'. We have to draw a line for moral policy, but it is unlikely we will ever discover a threshold. | |
| From: Daniel C. Dennett (Kinds of Minds [1996], Ch.4) | |
| A reaction: This is the only plausible view, if you take the theory of evolution seriously. We can even observe low-grade marginal sentience in our own minds, and then shoot up the scale when we focus our minds properly on an object. |
| 4873 | What is it like to notice an uncomfortable position when you are asleep? [Dennett] |
| Full Idea: What is it like to notice, while sound asleep, that your left arm has become twisted into a position in which it is putting undue strain on your left shoulder? Like nothing. | |
| From: Daniel C. Dennett (Kinds of Minds [1996], Ch.1) | |
| A reaction: A nice question, and all part of Dennett's accurate campaign to show that consciousness is not an all-or-nothing thing. As when we are barely aware of driving, innumerable things happen in the shadowy corners of thought. |
| 4881 | Being a person must involve having second-order beliefs and desires (about beliefs and desires) [Dennett] |
| Full Idea: An important step towards becoming a person is the step up from a first-order intentional system to a second-order system (which has beliefs and desires about beliefs and desires). | |
| From: Daniel C. Dennett (Kinds of Minds [1996], Ch.5) | |
| A reaction: Call it 'meta-thought'. I agree. Dennett thinks language is crucial to this, but the hallmark of intelligence and full-blown personhood is meta- and meta-meta-thought. Maybe the development of irony is a step up the evolutionary scale. Sarcasm is GOOD. |
| 2358 | Freedom is absence of opposition to action; the idea of 'free will' is absurd [Hobbes] |
| Full Idea: If a man should talk to me of a 'free-will', or any 'free' but free from being hindered by opposition, I should not say that he were in an error, but that his words were without a meaning, that is to say, absurd. | |
| From: Thomas Hobbes (Leviathan [1651], 1.05) |
| 6214 | Liberty and necessity are consistent, as when water freely flows, by necessity [Hobbes] |
| Full Idea: Liberty and necessity are consistent: as in the water, that hath not only liberty, but a necessity of descending by the channel. | |
| From: Thomas Hobbes (Leviathan [1651], II.Ch.XI) | |
| A reaction: Hume asserts something similar (Idea 2223), but they both miss the point, which is that libertarians about water would have to believe it didn't need to follow gravity, but could refuse to flow. Freedom of will and freedom of action are quite different. |
| 4875 | We descend from robots, and our intentionality is composed of billions of crude intentional systems [Dennett] |
| Full Idea: We are descended from robots, and composed of robots, and all the intentionality we enjoy is derived from the more fundamental intentionality of billions of crude intentional systems. | |
| From: Daniel C. Dennett (Kinds of Minds [1996], Ch.2) | |
| A reaction: A more grand view of intentionality (such as Searle's) seems more attractive than this, but the crucial fact about Dennett is that he takes the implications of evolution much more seriously than other philosophers. He's probably right. |
| 4879 | There is no more anger in adrenaline than silliness in a bottle of whiskey [Dennett] |
| Full Idea: There is no more fear or anger in adrenaline than there is silliness in a bottle of whiskey. | |
| From: Daniel C. Dennett (Kinds of Minds [1996], Ch.3) | |
| A reaction: Not exactly an argument, but a nice rhetorical point against absurd claims about identity and reduction and elimination. We may say that there is no fear without adrenaline, and no adrenaline in a live brain without fear. |
| 4876 | Maybe there is a minimum brain speed for supporting a mind [Dennett] |
| Full Idea: Perhaps there is a minimum speed for a mind, rather like the minimum escape velocity required to overcome gravity and leave the planet. | |
| From: Daniel C. Dennett (Kinds of Minds [1996], Ch.3) | |
| A reaction: Dennett rejects this speculation, but he didn't stop to imagine what it would be LIKE if your brain slowed down, and he never considers Edelman's view that mind is a process. Put the two together… |
| 4878 | The materials for a mind only matter because of speed, and a need for transducers and effectors [Dennett] |
| Full Idea: I think there are only two good reasons why, when you make a mind, the materials matter: speed, and the ubiquity of transducers and effectors throughout the nervous system. | |
| From: Daniel C. Dennett (Kinds of Minds [1996], Ch.3) | |
| A reaction: This sounds roughly right, because it gives you something between multiple realisability (minds made of cans and string), and type-type identity (minds ARE a particular material). Call it 'biological functionalism'? |
| 23987 | The 'simple passions' are appetite, desire, love, aversion, hate, joy, and grief [Hobbes, by Goldie] |
| Full Idea: For Hobbes the 'simple passions' were appetite, desire, love, aversion, hate, joy, and grief. | |
| From: report of Thomas Hobbes (Leviathan [1651], I.6) by Peter Goldie - The Emotions 4 'Evidence' | |
| A reaction: This is the standard approach to emotions of Hobbes's time. Modern thinkers probably reject the idea that passions can be simple or basic. Rightly, I think. |
| 4874 | The predecessor and rival of the language of thought hypothesis is the picture theory of ideas [Dennett] |
| Full Idea: The ancestor and chief rival of the language-of-thought hypothesis is the picture theory of ideas - that thoughts are about what they are about because they resemble their objects. | |
| From: Daniel C. Dennett (Kinds of Minds [1996], Ch.2) | |
| A reaction: When you place them side by side, neither seems quite right. How can a mental state resemble an object, and how can an inner language inherently capture the features of an object? Maybe we lack the words for the correct theory. |
| 4882 | Concepts are things we (unlike dogs) can think about, because we have language [Dennett] |
| Full Idea: A dog cannot consider its concepts. Concepts are not things in a dog's world in the way that cats are. Concepts are things in our world, because we have language. | |
| From: Daniel C. Dennett (Kinds of Minds [1996], Ch.6) | |
| A reaction: Dogs must have concepts, though, or much of their behaviour (like desperation to go for a walk, or to eat) is baffling. This is as good a proposal as I have ever encountered for the value of language. Meta-thought is a huge evolutionary advantage. |
| 2362 | The will is just the last appetite before action [Hobbes] |
| Full Idea: In deliberation, the last appetite or aversion immediately adhering to the action, or to the omission thereof, is that we call the Will. | |
| From: Thomas Hobbes (Leviathan [1651], 1.06) | |
| A reaction: I share his caution about 'the will', but his observation strikes me as inaccurate. When I drink, my 'will' is not my thirst. I take the will to be a feature of my reason. I gave my thirst permission to indulge itself. The will is practical reason? |
| 2363 | Reason is usually general, but deliberation is of particulars [Hobbes] |
| Full Idea: Reasoning is in general words, but deliberation for the most part is of particulars. | |
| From: Thomas Hobbes (Leviathan [1651], 1.06) |
| 2360 | 'Good' is just what we desire, and 'Evil' what we hate [Hobbes] |
| Full Idea: Whatsoever is the object of any man's appetite or desire, that is it which he for his part calleth 'Good'; and the object of his hate or aversion 'Evil'. | |
| From: Thomas Hobbes (Leviathan [1651], 1.06) | |
| A reaction: This meets the Frege-Geach Problem - that we can have these feelings while reading ancient history, but we can't possibly 'desire' any of that. This is better on evil than on good. |
| 2368 | Men's natural desires are no sin, and neither are their actions, until law makes it so [Hobbes] |
| Full Idea: The desires and other passions of man are in themselves no sin. No more are the actions that proceed from those passions, till they know a law that forbids them. | |
| From: Thomas Hobbes (Leviathan [1651], 1.13) | |
| A reaction: That is a pretty flat rejection of natural law, as you might expect from an empiricist. So prior to the first law-making, no one ever did anything wrong? Hm. |
| 2359 | Desire and love are the same, but in the desire the object is absent, and in love it is present [Hobbes] |
| Full Idea: Desire and love are the same thing, save that by desire we always signify the absence of the object, by love most commonly the presence of the same. | |
| From: Thomas Hobbes (Leviathan [1651], 1.06) | |
| A reaction: Implausible reductivism from Hobbes. Plenty of counterexamples to this. You work it out! |
| 2370 | All voluntary acts aim at some good for the doer [Hobbes] |
| Full Idea: Of the voluntary acts of every man, the object is some good to himself. | |
| From: Thomas Hobbes (Leviathan [1651], 1.14) | |
| A reaction: Nonsense. You can only describe sacrificial acts for loved ones, such as children, in this way if this proposal is a tautology. Hobbes cannot know the truth of this claim. |
| 8015 | Hobbes wants a contract to found morality, but shared values are needed to make a contract [MacIntyre on Hobbes] |
| Full Idea: Hobbes makes two incompatible demands of the original contract: he wishes it to be the foundation of all shared and common standards and rules; but he also wishes it to be a contract, which needs prior shared and common standards. | |
| From: comment on Thomas Hobbes (Leviathan [1651], Pt 1) by Alasdair MacIntyre - A Short History of Ethics Ch.10 | |
| A reaction: At the very least, the participants in a contract must be committed to keeping it even when it is not convenient. But a common purpose seems to be needed too, which makes the contract itself intrinsically valuable. Similar objections to Kant. |
| 2371 | A contract is a mutual transfer of rights [Hobbes] |
| Full Idea: The mutual transferring of right is that which men call 'contract'. | |
| From: Thomas Hobbes (Leviathan [1651], 1.14) |
| 2372 | The person who performs first in a contract is said to 'merit' the return, and is owed it [Hobbes] |
| Full Idea: He that performeth first in the case of a contract, is said to 'merit' that which he is to receive by the performance of the other, and he hath it as due. | |
| From: Thomas Hobbes (Leviathan [1651], 1.14) |
| 5337 | For Hobbes the Golden Rule concerns not doing things, whereas Jesus encourages active love [Hobbes, by Flanagan] |
| Full Idea: Hobbes put the Golden Rule as 'do NOT do to others what you would NOT want done to yourself'. Jesus's formulation encouraged active love. Most Westerners conceive their moral duty as not to do harm, rather than actively doing good. | |
| From: report of Thomas Hobbes (Leviathan [1651]) by Owen Flanagan - The Problem of the Soul p.20n | |
| A reaction: This idea probably runs very deep into western culture, where most people feel that they are being very morally good when they are sitting at home and not actually annoying anyone. Utilitarianism also offers a challenge to such complacency. |
| 2374 | In the violent state of nature, the merest suspicion is enough to justify breaking a contract [Hobbes] |
| Full Idea: If a covenant is made with neither party performing presently, but trust one another, in the condition of mere nature (which is war between men) upon reasonable suspicion, it is void. | |
| From: Thomas Hobbes (Leviathan [1651], 1.14) |
| 8016 | Fear of sanctions is the only motive for acceptance of authority that Hobbes can think of [MacIntyre on Hobbes] |
| Full Idea: Hobbes has such a limited view of human motives that he cannot provide any other explanation for the acceptance of authority than the fear of sanctions.. | |
| From: comment on Thomas Hobbes (Leviathan [1651], Pt 1) by Alasdair MacIntyre - A Short History of Ethics Ch.10 | |
| A reaction: There are two alternative views - the conservative view that people naturally welcome and even need authority, because they need to be led; or the Aristotelian view that people are naturally communal, and authority is part of community life. |
| 2375 | Suspicion will not destroy a contract, if there is a common power to enforce it [Hobbes] |
| Full Idea: If there be a common power set over both parties in a contract, with right and force sufficient to compel performance, a contract does not become void as soon as the parties are suspicious. | |
| From: Thomas Hobbes (Leviathan [1651], 1.14) |
| 2377 | No one who admitted to not keeping contracts could ever be accepted as a citizen [Hobbes] |
| Full Idea: He therefore that breaketh his covenant, and consequently declareth that he thinks he may with reason do so, cannot be received into any society. | |
| From: Thomas Hobbes (Leviathan [1651], 1.15) |
| 2379 | If there is a good reason for breaking a contract, the same reason should have stopped the making of it [Hobbes] |
| Full Idea: If any fault of man be sufficient to discharge our covenant made, the same ought in reason to have been sufficient to have hindered the making of it. | |
| From: Thomas Hobbes (Leviathan [1651], 1.15) |
| 2373 | The first performer in a contract is handing himself over to an enemy [Hobbes] |
| Full Idea: He which performeth first in a contract, does but betray himself to his enemy. | |
| From: Thomas Hobbes (Leviathan [1651], 1.14) |
| 2382 | Someone who keeps all his contracts when others are breaking them is making himself a prey to others [Hobbes] |
| Full Idea: He that should be modest and tractable, and perform all the promises, in such time and place where no man else should do so, should but make himself a prey to others. | |
| From: Thomas Hobbes (Leviathan [1651], 1.15) |
| 2383 | Virtues are a means to peaceful, sociable and comfortable living [Hobbes] |
| Full Idea: The writers of moral philosophy, though they acknowledge the same virtues and vices, yet not seeing wherein consisted their goodness, nor that they come to be praised as the means of peaceable, sociable and comfortable living. | |
| From: Thomas Hobbes (Leviathan [1651], 1.15) |
| 2376 | Injustice is the failure to keep a contract, and justice is the constant will to give what is owed [Hobbes] |
| Full Idea: The definition of 'injustice' is no other than the not performance of covenant….. and 'justice' is the constant will of giving to every man his own. | |
| From: Thomas Hobbes (Leviathan [1651], 1.15) |
| 2367 | In time of war the life of man is solitary, poor, nasty, brutish and short [Hobbes] |
| Full Idea: In a time of war…. there is continual fear, and danger of violent death, and the life of man is solitary, poor, nasty, brutish and short. | |
| From: Thomas Hobbes (Leviathan [1651], 1.13) |
| 19764 | Hobbes attributed to savages the passions which arise in a law-bound society [Hobbes, by Rousseau] |
| Full Idea: Hobbes had wrongly injected into the savage man's concern for self-preservation the need to satisfy a multitude of passions which are the product of society and which have made laws necessary. | |
| From: report of Thomas Hobbes (Leviathan [1651]) by Jean-Jacques Rousseau - Discourse on the Origin of Inequality Part I | |
| A reaction: Hobbes's famous remark concerns a state of war, which is quite a sophisticated state of conflict between well formed social groups. Rousseau's savage is fairly solitary, so won't be involved in war. |
| 20566 | Hobbes says the people voluntarily give up their sovereignty, in a contract with a ruler [Hobbes, by Oksala] |
| Full Idea: While Hobbes had held that the people were the final source of political authority, he had argued that in entering the social contract they gave up their sovereignty by transferring all power to an absolute ruler. | |
| From: report of Thomas Hobbes (Leviathan [1651]) by Johanna Oksala - Political Philosophy: all that matters Ch.5 | |
| A reaction: Later the idea of 'inalienable' rights crept in. If you volunteer for exploitation or slavery, that still doesn't justify them. Sadism is presumably not justified by masochism. |
| 2366 | There is not enough difference between people for one to claim more benefit than another [Hobbes] |
| Full Idea: The difference between man and man is not so considerable as that one man can thereupon claim to himself any benefit to which another may not pretend as well as he. | |
| From: Thomas Hobbes (Leviathan [1651], 1.13) |
| 20485 | Hobbes says people are roughly equal; Locke says there is no right to impose inequality [Hobbes, by Wolff,J] |
| Full Idea: Hobbes's principle of equality was a claim about the mental and physical capabilities of all people. For Locke it is a moral claim about rights: no person has a natural right to subordinate any other. | |
| From: report of Thomas Hobbes (Leviathan [1651]) by Jonathan Wolff - An Introduction to Political Philosophy (Rev) 1 'Locke' | |
| A reaction: There are obvious questions to ask about the claim that people are naturally equal. For the second one, does the lion have a natural right to subordinate the gazelle? Who cares! I'm inclined to be consequentialist about equality. |
| 2369 | If we seek peace and defend ourselves, we must compromise on our rights [Hobbes] |
| Full Idea: From the first law of nature (that we seek peace, but also defend ourselves) comes the second: that a man be willing to lay down his rights to all things, and be contented with so much liberty against other men as he would allow other men against himself. | |
| From: Thomas Hobbes (Leviathan [1651], 1.14) |
| 20484 | We should obey the laws of nature, provided other people are also obeying them [Hobbes, by Wolff,J] |
| Full Idea: Hobbes's position is that we have a duty to obey the Laws of Nature when others around us are known (or can reasonably be expected) to be obeying them too, and so our compliance will not be exploited. | |
| From: report of Thomas Hobbes (Leviathan [1651]) by Jonathan Wolff - An Introduction to Political Philosophy (Rev) 1 'Hobbes' | |
| A reaction: In particular, we should keep contracts. Hobbes doesn't seem fully committed to keeping facts and values separate. |
| 7573 | The legal positivism of Hobbes said law is just formal or procedural [Hobbes, by Jolley] |
| Full Idea: Hobbes was one of the first to propose the view known as 'legal positivism' - that the criterion for deciding whether a rule is a genuine law is entirely formal or procedural | |
| From: report of Thomas Hobbes (Leviathan [1651]) by Nicholas Jolley - Leibniz Ch.7 | |
| A reaction: This was opposed to the tradition of natural law, deriving from Aquinas. It is part of a picture of values draining out of the world as science comes to dominate. The is/ought distinction is its culmination. Power replaces virtue, and Thrasymachus wins. |
| 2380 | Punishment should only be for reform or deterrence [Hobbes] |
| Full Idea: We are forbidden to inflict punishment with any other design than for correction of the offender, or direction of others. | |
| From: Thomas Hobbes (Leviathan [1651], 1.15) |
| 2361 | If fear of unknown powers is legal it is religion, if it is illegal it is superstition [Hobbes] |
| Full Idea: Fear of power invisible, feigned by the mind or imagined from tales publicly allowed, is religion; not allowed, is superstition. | |
| From: Thomas Hobbes (Leviathan [1651], 1.06) |
| 4872 | Most people see an abortion differently if the foetus lacks a brain [Dennett] |
| Full Idea: If a fetus that is being considered for abortion is known to be anencephalic (lacking a brain), this dramatically changes the issue for most people, though not for all. | |
| From: Daniel C. Dennett (Kinds of Minds [1996], Ch.1) | |
| A reaction: A very effective point, as it is hard to see what grounds could be given for not aborting in this case. But the brain then clearly becomes the focus of why abortion is often rejected by many people. |
| 3535 | All observable causes are merely epiphenomena [Kim] |
| Full Idea: All causal relations involving observable phenomena - all causal relations from daily experience - are cases of epiphenomenal causation. | |
| From: Jaegwon Kim (Epiphenomenal and supervenient causation [1984], §2) |
| 2364 | Causation is only observation of similar events following each other, with nothing visible in between [Hobbes] |
| Full Idea: In knowing the meaning of 'causing', men can only observe and remember what they have seen to precede the like effect at some other time, without seeing between the antecedent and subsequent event any dependence or connexion at all. | |
| From: Thomas Hobbes (Leviathan [1651], 1.12) |
| 4877 | Maybe plants are very slow (and sentient) animals, overlooked because we are faster? [Dennett] |
| Full Idea: Might plants just be 'very slow animals', enjoying sentience that has been overlooked by us because of our human timescale chauvinism? | |
| From: Daniel C. Dennett (Kinds of Minds [1996], Ch.3) | |
| A reaction: Delightful thought, arising from pondering the significance of the speed of operation of the brain. I think it is false, because I think high speed is essential to mind, and Dennett seems not to. |
| 2365 | Religion is built on ignorance and misinterpretation of what is unknown or frightening [Hobbes] |
| Full Idea: In these four things - opinion of ghosts, ignorance of second causes, devotion towards what men fear, and taking of things casual for prognostics, consisteth the natural seed of religion. | |
| From: Thomas Hobbes (Leviathan [1651], 1.12) |
| 2378 | Belief in an afterlife is based on poorly founded gossip [Hobbes] |
| Full Idea: Knowledge of man's estate after death, and its rewards, is a belief grounded upon other men's sayings that they knew it supernaturally, or they knew those, that knew those, that knew others, that knew it supernaturally. | |
| From: Thomas Hobbes (Leviathan [1651], 1.15) |
