6259 | Why can't a wise man doubt everything? [Montaigne] |
Full Idea: Why cannot a wise man dare to doubt anything and everything? | |
From: Michel de Montaigne (Apology for Raymond Sebond [1580], p.0562) | |
A reaction: This question seems to be the start of the Enlightenment Project, of attempting to prove everything. MacIntyre warns of the dangers of this in ethical theory. The story of modern philosophy is the discovery of its impossibility. E.g. Davidson on truth. |
6263 | No wisdom could make us comfortably walk a wide beam if it was high in the air [Montaigne] |
Full Idea: Take a beam wide enough to walk along: suspend it between two towers: there is no philosophical wisdom, however firm, which could make us walk along it just as we would if we were on the ground. | |
From: Michel de Montaigne (Apology for Raymond Sebond [1580], p.0672) | |
A reaction: This proposes great scepticism about the practical application of philosophical wisdom, but if we talk in terms of the wise assessment of risk in any undertaking, our caution on the raised beam makes perfectly good sense. |
23122 | Montaigne was the founding father of liberalism [Montaigne, by Gopnik] |
Full Idea: The first liberal, the founding father if we have one, is the great sixteenth century French essayist Michel de Montaigne. | |
From: report of Michel de Montaigne (On Cruelty [1580]) by Adam Gopnik - A Thousand Small Sanities 1 | |
A reaction: He says this not on the basis of his politicies or achievements, but his general attitudes and values. It may be another hundred years before we can identify another obvious liberal (Locke?). |
4739 | In "if and only if" (iff), "if" expresses the sufficient condition, and "only if" the necessary condition [Engel] |
Full Idea: Necessary and sufficient conditions are usually expressed by "if and only if" (abbr. "iff"), where "if" is the sufficient condition, and "only if" is the necessary condition. | |
From: Pascal Engel (Truth [2002], §1.1) | |
A reaction: 'I take my umbrella if and only if it is raining' (oh, and if I'm still alive). There may be other necessary conditions than the one specified. Oh, and I take it if my wife slips it into my car… |
6258 | Virtue is the distinctive mark of truth, and its greatest product [Montaigne] |
Full Idea: The distinctive mark of the Truth we hold ought to be virtue, which is the most exacting mark of Truth, the closest one to heaven and the most worthy thing that Truth produces. | |
From: Michel de Montaigne (Apology for Raymond Sebond [1580], p.0493) | |
A reaction: A long way from Tarski and minimalist theories of truth! But not so far from pragmatism. Personally I think Montaigne is making an important claim, which virtue theorists should be attempting to incorporate into their theory. Aristotle would sympathise. |
4737 | Are truth-bearers propositions, or ideas/beliefs, or sentences/utterances? [Engel] |
Full Idea: The tradition of the Stoics and Frege says that truth-bearers are propositions, Descartes and the classical empiricist say they are ideas or beliefs, and Ockham and Quine say they are sentences or utterances. | |
From: Pascal Engel (Truth [2002], §1.1) | |
A reaction: I'm with propositions, which are unambiguous, can be expressed in a variety of ways, embody the 'logical form' of sentences, and could be physically embodied in brains (the language of thought?). |
4750 | The redundancy theory gets rid of facts, for 'it is a fact that p' just means 'p' [Engel] |
Full Idea: The redundancy theory gets rid of facts, for 'it is a fact that p' just means 'p'. | |
From: Pascal Engel (Truth [2002], §2.2) | |
A reaction: But then when you ask what p means, you have to give the truth-conditions for its assertion, and you find you have to mention the facts after all. |
4744 | We can't explain the corresponding structure of the world except by referring to our thoughts [Engel] |
Full Idea: The correspondence theory implies displaying an identity or similarity of structure between the contents of thoughts and the way the world is structured, but we seem only to be able to say that the world's structure corresponds to our thoughts. | |
From: Pascal Engel (Truth [2002], §1.2) | |
A reaction: I don't accept this. The structure of the world gives rise to our thoughts. There is an epistemological problem here (big time!), but that doesn't alter the metaphysical situation of what truth is supposed to be, which is correspondence. |
4738 | The coherence theory says truth is an internal relationship between groups of truth-bearers [Engel] |
Full Idea: The coherence theory of truth says that it is a relationship between truth-bearers themselves, that is between propositions or beliefs or sentences. | |
From: Pascal Engel (Truth [2002], §1.1) | |
A reaction: We immediately begin to wonder how many truth-bearers are required. Two lies can be coherent. It is hard to make thousands of lies coherent, but not impossible. What fixes the critical number. 'All possible propositions' is not much help. |
4745 | Any coherent set of beliefs can be made more coherent by adding some false beliefs [Engel] |
Full Idea: Any coherent set of beliefs can be made more coherent by adding to it one or more false beliefs. | |
From: Pascal Engel (Truth [2002], §1.3) | |
A reaction: A simple but rather devastating point. It is the policeman manufacturing a bogus piece of evidence to clinch the conviction, the scientist faking a single observation to fill in the last corner of a promising theory. |
4753 | Deflationism seems to block philosophers' main occupation, asking metatheoretical questions [Engel] |
Full Idea: Deflationism about truth seems to deprive us of any hope of asking genuinely metatheoretical questions, which are the questions that occupy philosophers most of the time. | |
From: Pascal Engel (Truth [2002], §2.5) | |
A reaction: This seems like the best reason for moving from deflationism to at least minimalism. Clearly one can talk meaningfully about the success of assertions and theories. You can say a sentence is true, but not assert it. |
4755 | Deflationism cannot explain why we hold beliefs for reasons [Engel] |
Full Idea: The deflationist view is silent about the fact that our assertions and beliefs are generally made or held for certain reasons. | |
From: Pascal Engel (Truth [2002], §2.5) | |
A reaction: The point here must be that I attribute strength to my beliefs, depending on how much support I have for them - how much support for their real truth. I scream "That's really TRUE!" when I have very good reasons. |
4751 | Maybe there is no more to be said about 'true' than there is about the function of 'and' in logic [Engel] |
Full Idea: We could compare the status of 'true' with the status of the logical operator 'and' in logic. Once we have explained how it functions to conjoin two propositions, there is not much more to be said about it. | |
From: Pascal Engel (Truth [2002], §2.4) | |
A reaction: A good statement of the minimalist view. I don't believe it, because I don't believe that truth is confined to language. An uneasy feeling I can't put into words can turn out to be true. Truth is a relational feature of mental states. |
4752 | Deflationism must reduce bivalence ('p is true or false') to excluded middle ('p or not-p') [Engel] |
Full Idea: It is said that deflationism cannot even formulate the principle of bivalence, for 'either p is true or p is false' will amount to the principle of excluded middle, 'either p or not-p'. | |
From: Pascal Engel (Truth [2002], §2.4) | |
A reaction: Presumably deflationists don't lost any sleep over this - in fact, it looks like a good concise way to state the deflationist thesis. However, excluded middle refers to a proposition (not-p) that was never mentioned by bivalence. Cf Idea 6163. |
6262 | We lack some sense or other, and hence objects may have hidden features [Montaigne] |
Full Idea: We may all lack some sense or other; because of that defect, most of the features of objects may be concealed from us. | |
From: Michel de Montaigne (Apology for Raymond Sebond [1580], p.0666) | |
A reaction: This strikes me as simple, straightforward common sense, and right. I cannot make sense of the claim that reality really is just the way it appears. We do not have a built-in neutrino detector, for example. |
4762 | The Humean theory of motivation is that beliefs may be motivators as well as desires [Engel] |
Full Idea: A problem for the Humean theory of motivation is that it is disputed that beliefs are only representational states, which cannot, unlike desires, move us to act. | |
From: Pascal Engel (Truth [2002], §4.2) | |
A reaction: This is a crucial issue for Humeans and empiricists. Rationalists claim that people act for reasons, so that reasons are intrinsically motivational (like the Form of the Good), and reasons may even be considered direct causes of actions. |
4754 | Our beliefs are meant to fit the world (i.e. be true), where we want the world to fit our desires [Engel] |
Full Idea: Belief is said to 'aim at truth', in the sense that beliefs are the kind of mental states that have to be true for the mind to 'fit' the world (where our desires have the opposite 'direction of fit'; the world is supposed to fit our desires). | |
From: Pascal Engel (Truth [2002], §2.5) | |
A reaction: I don't think it is possible to give a plausible definition of belief without mentioning truth. Hume's account of them as thoughts with a funny feeling attached is ridiculous. Thinking is an activity, not a passive state. |
4763 | 'Evidentialists' say, and 'voluntarists' deny, that we only believe on the basis of evidence [Engel] |
Full Idea: The 'evidentialists' (such as Locke and Hume) deny, and the 'voluntarists' (such as William James) affirm, that we ought to, or at least may, believe for other reasons than evidential epistemic reasons (e.g. for pragmatic reasons). | |
From: Pascal Engel (Truth [2002], §5.2) | |
A reaction: No need to be black-or-white here. Blatant evidence compels belief, but we may also come to believe by spotting a coherence, without additional evidence. We can also be in a state of trying to believe something. But see 4764. |
4746 | Pragmatism is better understood as a theory of belief than as a theory of truth [Engel] |
Full Idea: Pragmatism in general is better construed as a certain conception of belief, rather than as a distinctive conception of truth. | |
From: Pascal Engel (Truth [2002], §1.5) | |
A reaction: Which is why aspiring relativists drift towards the pragmatic theory - because they want to dispense with truth (and hence knowledge), and put mere belief in its place. |
4764 | We cannot directly control our beliefs, but we can control the causes of our involuntary beliefs [Engel] |
Full Idea: Direct psychological voluntarism about beliefs seems to be false, but we can have an indirect voluntary control on many of our beliefs, by manipulating the states in us that are involuntary and which lead to certain beliefs. | |
From: Pascal Engel (Truth [2002], §5.2) | |
A reaction: Very nice! This points two ways - to scientific experiments, which can have compelling outcomes (see Fodor), and to brain-washing, and especially auto-brainwashing (only reading articles which support your favourites theories). What magazines do you take? |
6260 | Sceptics say there is truth, but no means of making or testing lasting judgements [Montaigne] |
Full Idea: Pyrrhonians say that truth and falsehood exist; within us we have means of looking for them, but not of making any lasting judgements: we have no touchstone. | |
From: Michel de Montaigne (Apology for Raymond Sebond [1580], p.0564) | |
A reaction: This states the key difference between sceptics and relativists. The latter are more extreme as they say there is no such thing as truth. The former concede truth, and their scepticism is about the abilities of human beings. I am an anti-relativist. |
6261 | The soul is in the brain, as shown by head injuries [Montaigne] |
Full Idea: The seat of the powers of the soul is in the brain, as is clearly shown by the fact that wounds and accidents affecting the head immediately harm the faculties of the soul. | |
From: Michel de Montaigne (Apology for Raymond Sebond [1580], p.0614) | |
A reaction: At last someone has finally got the facts clear. It seems surprising that the Greeks never clearly grasped this piece of irrefutable evidence - even those Greeks who speculated that the brain was the key. Here we have a fixed fact of philosophy of mind. |
4759 | Mental states as functions are second-order properties, realised by first-order physical properties [Engel] |
Full Idea: For functionalism mental states as roles are second-order properties that have to be realised in various ways in first-order physical properties. | |
From: Pascal Engel (Truth [2002], §3.3) | |
A reaction: I take that to be properties-of-properties, as in 'bright red' or 'poignantly beautiful'. I am inclined to think (with Edelman) that mind is a process, not a property. |
7496 | Rules and duties are based on the will, as that is all we control [Montaigne] |
Full Idea: Since actions and performances are not wholly in our power and since nothing is really in our power but our will - it is on the will that all the rules and duties of Man are based and established. | |
From: Michel de Montaigne (I.7 Our deeds are judged by intention [1580], p.0028) | |
A reaction: This is almost Kant's claim that the only truly good thing is a good will (e.g. Idea 3711). Aristotle disagrees, because a virtuous person should also have good desires. We may will to have good desires, but virtue requires actually having them. |
7495 | Apart from the fear, dying is an easy duty [Montaigne] |
Full Idea: If our fears did not lend it weight, dying would be one of our lighter duties. | |
From: Michel de Montaigne (III.12 On physiognomy [1580], p.1191) | |
A reaction: An Epicurean thought. 'Duties' is nice - presumably death qualifies as a duty, because Nature requires it of us (we each of us 'owe nature a death'). The remark appears to me to be true. |
22269 | We must fight fiercely to hang on to the few pleasures which survive into old age [Montaigne] |
Full Idea: I am training and sharpening my appetite for those pleasures that are left. ...We must cling tooth and claw to the use of the pleasures of this life which the advancing years, one after another, rip from our grasp. | |
From: Michel de Montaigne (I.39 On Solitude [1580], p.276) | |
A reaction: That may be one of the most inspiring ideas I have read about pleasure. |
20482 | Virtue inspires Stoics, but I want a good temperament [Montaigne] |
Full Idea: What Stoics did from virtue I teach myself to do from temperament. | |
From: Michel de Montaigne (III.10 On Restraining your Will [1580], p.1153) | |
A reaction: I take this to be an Aristotelian criticism of Stoicism. They venerate virtue above everything, but Aristotle says you must integrate virtue into your very being, so that right actions flow from you, with very little need for premeditation. |
20480 | There is not much point in only becoming good near the end of your life [Montaigne] |
Full Idea: It is almost better never to become a good man at all than to do so tardily, understanding how to live when you have no life left. | |
From: Michel de Montaigne (III.10 On Restraining your Will [1580], p.1142) | |
A reaction: A very nice perspective, which I don't recall Aristotle mentioning. It does, though, reinforce Aristotle's belief that early training is essential. |
20481 | Nothing we say can be worse than unsaying it in the face of authority [Montaigne] |
Full Idea: Nothing which a gentleman says can seem worse than the shame of his unsaying it under duress from authority. | |
From: Michel de Montaigne (III.10 On Restraining your Will [1580], p.1153) | |
A reaction: The point is that you have to fight every day for free speech, because no matter what the law says, there are always people in power who want to shut you up. |
20479 | People at home care far more than soldiers risking death about the outcome of wars [Montaigne] |
Full Idea: How many soldiers put themselves at risk every day in wars which they care little about, rushing into danger in battles the loss of which will not make them lose a night's sleep. Meanwhile a man at home is more passionate about the war than the soldier. | |
From: Michel de Montaigne (III.10 On Restraining your Will [1580], p.1139) | |
A reaction: It depends whether you are a mercenary (which the majority probably were in 1680), and what are the implications of defeat. |
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) |
