| 12926 | Wisdom is the science of happiness [Leibniz] |
| Full Idea: Wisdom is the science of happiness. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1690.03.23) | |
| A reaction: That probably comes down to common sense, or Aristotle's 'phronesis'. I take wisdom to involve understanding, as well as the quest for happiness. |
| 12903 | Wise people have fewer acts of will, because such acts are linked together [Leibniz] |
| Full Idea: The wiser one is, the fewer separate acts of will one has and the more one's views and acts of will are comprehensive and linked together. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.04.12) | |
| A reaction: [letter to Landgrave, about Arnauld] It is unusual to find a philosopher who actually tries to analyse the nature of wisdom, instead of just paying lipservice to it. I take Leibniz to be entirely right here. He equates wisdom with rational behaviour. |
| 12914 | Metaphysics is geometrical, resting on non-contradiction and sufficient reason [Leibniz] |
| Full Idea: I claim to give metaphysics geometric demonstrations, assuming only the principle of contradiction (or else all reasoning becomes futile), and that nothing exists without a reason, or that every truth has an a priori proof, from the concept of terms. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14 XI) | |
| A reaction: For the last bit, see Idea 12910. This idea is the kind of huge optimism about metaphysic which got it a bad name after Kant, and in modern times. I'm optimistic about metaphysics, but certainly not about 'geometrical demonstrations' of it. |
| 23917 | Contrary statements can both be reasonable, if they are meant in two different ways [Aristotle] |
| Full Idea: Contrary things can be reasonably held …because the contrary positions will stand if what is said is true in one way, but not true in another. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1235b17) | |
| A reaction: My strategy here is to clarify the unambiguous underlying propositions which are being expressed. There will then be either agreement, or flat contradiction. |
| 12915 | Definitions can only be real if the item is possible [Leibniz] |
| Full Idea: Definitions to my mind are real, when one knows that the thing defined is possible; otherwise they are only nominal, and one must not rely on them. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14 XI) | |
| A reaction: It is interesting that things do not have to actual to have real definitions. For Leibniz, what is possible will exist in the mind of God. For me what is possible will exist in the potentialities of the powers of what is actual. |
| 19333 | A truth is just a proposition in which the predicate is contained within the subject [Leibniz] |
| Full Idea: In every true affirmative proposition, necessary or contingent, universal or particular, the concept of the predicate is in a sense included in that of the subject; the predicate is present in the subject; or else I do not know what truth is. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14) | |
| A reaction: Why did he qualify this with "in a sense"? This is referred to as the 'concept containment theory of truth'. This is an odd view of the subject. If the truth is 'Peter fell down stairs', we don't usually think the concept of Peter contains such things. |
| 12910 | The predicate is in the subject of a true proposition [Leibniz] |
| Full Idea: In a true proposition the concept of the predicate is always present in the subject. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14 X) | |
| A reaction: This sounds very like the Kantian notion of an analytic truth, but Leibniz is applying it to all truths. So Socrates must contain the predicate of running as part of his nature (or essence?), if 'Socrates runs' is to be true. |
| 12920 | There is no multiplicity without true units [Leibniz] |
| Full Idea: There is no multiplicity without true units. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.04.30) | |
| A reaction: Hence real numbers do not embody 'multiplicity'. So either they don't 'embody' anything, or they embody 'magnitudes'. Does this give two entirely different notions, of measure of multiplicity and measures of magnitude? |
| 12319 | What is not truly one being is not truly a being either [Leibniz] |
| Full Idea: What is not truly one being is not truly a being either. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.04.30), quoted by Alain Badiou - Briefings on Existence 1 | |
| A reaction: Badiou quotes this as identifying Being with the One. I say Leibniz had no concept of 'gunk', and thought everything must have a 'this' identity in order to exist, which is just the sort of thing a logician would come up with. |
| 12922 | A thing 'expresses' another if they have a constant and fixed relationship [Leibniz] |
| Full Idea: One thing 'expresses' another (in my terminology) when there exists a constant and fixed relationship between what can be said of one and of the other. This is the way that a perspectival projection expresses its ground-plan. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.10.09) | |
| A reaction: Arnauld was puzzled by what Leibniz might mean by 'express', and it occurs to me that Leibniz was fishing for the modern concept of 'supervenience'. It also sounds a bit like the idea of 'covariance' between mind and world. Maybe he means 'function'. |
| 13079 | A substance contains the laws of its operations, and its actions come from its own depth [Leibniz] |
| Full Idea: Each indivisible substance contains in its nature the law by which the series of its operations continues, and all that has happened and will happen to it. All its actions come from its own depths, except for dependence on God. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1688.01.4/14) | |
| A reaction: I take the combination of 'laws' and 'forces', which Leibniz attributes to Aristotelian essences, to be his distinctive contribution towards giving us an Aristotelian metaphysic which is suitable for modern science. |
| 5869 | The thesis of the Form of the Good (or of anything else) is verbal and vacuous [Aristotle] |
| Full Idea: The thesis that there is a Form either of good or indeed of anything else is verbal and vacuous. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1217b20) | |
| A reaction: This is clear evidence for suggesting that Aristotle is a nominalist. Elsewhere his essentialism suggests otherwise, but clearly on grumpy days he thought that universals were mere verbal conventions. |
| 12745 | Philosophy needs the precision of the unity given by substances [Leibniz] |
| Full Idea: Philosophy cannot be better reduced to something precise, than by recognising only substances or complete beings endowed with a true unity, with different states that succeed one another; all else is phenomena, abstractions or relations. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.04.30), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 7 | |
| A reaction: This idea bothers me. Has the whole of modern philosophy been distorted by this yearning for 'precision'? It has put mathematicians and logicians in the driving seat. Do we only attribute unity because it suits our thinking? |
| 12921 | Accidental unity has degrees, from a mob to a society to a machine or organism [Leibniz] |
| Full Idea: There are degrees of accidental unity, and an ordered society has more unity than a chaotic mob, and an organic body or a machine has more unity than a society. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.04.30) | |
| A reaction: This immediately invites questions about the extremes. Why does the very highest degree of 'accidental unity' not achieve 'true unity'? And why cannot a very ununified aggregate have a bit of unity (as in unrestricted mereological composition)? |
| 12746 | We find unity in reason, and unity in perception, but these are not true unity [Leibniz] |
| Full Idea: A pair of diamonds is merely an entity of reason, and even if one of them is brought close to another, it is an entity of imagination or perception, that is to say a phenomenon; contiguity, common movement and the same end don't make substantial unity. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.04.30), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 7 | |
| A reaction: This invites the question of what you have to do to two objects to give them substantial unity. The distinction between unity 'of reason' and unity 'of perception' is good. |
| 12916 | A body is a unified aggregate, unless it has an indivisible substance [Leibniz] |
| Full Idea: One will never find a body of which it may be said that it is truly one substance, ...because entities made up by aggregation have only as much reality as exists in the constituent parts. Hence the substance of a body must be indivisible. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.11) | |
| A reaction: Leibniz rejected atomism, and he evidently believed that pure materialists must deny the real existence of physical objects. Common sense suggests that causal bonds bestow a high degree of unity on bodies (if degrees are allowed). |
| 12919 | Unity needs an indestructible substance, to contain everything which will happen to it [Leibniz] |
| Full Idea: Substantial unity requires a complete, indivisible and naturally indestructible entity, since its concept embraces everything that is to happen to it, which cannot be found in shape or motion. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.11.28/12.8) | |
| A reaction: Hence if a tile is due to be broken in half (Arnauld's example), it cannot have had unity in the first place. To what do we refer when we say 'the tile was broken'? |
| 12923 | Every bodily substance must have a soul, or something analogous to a soul [Leibniz] |
| Full Idea: Every bodily substance must have a soul, or at least an entelechy which is analogous to the soul. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.10.09) | |
| A reaction: He routinely commits to a 'soul', and then pulls back and says it may only be an 'analogy'. He had deep doubts about his whole scheme, which emerged in the late correspondence with Des Bosses. This not monads, says Garber. |
| 12704 | Aggregates don’t reduce to points, or atoms, or illusion, so must reduce to substance [Leibniz] |
| Full Idea: In aggregates one must necessarily arrive either at mathematical points from which some make up extension, or at atoms (which I dismiss), or else no reality can be found in bodies, or finally one must recognises substances that possess a true unity. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.04.30), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 2 | |
| A reaction: Garber calls this Leibniz's Aggregate Argument. Leibniz is, of course, talking of physical aggregates which have unity. He consistently points out that a pile of logs has no unity at all. But is substance just that-which-provides-unity? |
| 13077 | Basic predicates give the complete concept, which then predicts all of the actions [Leibniz] |
| Full Idea: Apart from those that depend on others, one must only consider together all the basic predicates in order to form the complete concept of Adam adequate to deduce from it everything that is ever to happen to him, as much as is necessary to account for it. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.06) | |
| A reaction: This (implausibly) goes beyond mere prediction of properties. Eve's essence seems to be relevant to Adam's life. Note that the complete concept is not every predicate, but only those 'necessary' to predict the events. Cf Idea 13082. |
| 12908 | Essences exist in the divine understanding [Leibniz] |
| Full Idea: Essences exist in the divine understanding before one considers will. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14 X) | |
| A reaction: This is a sort of religious neo-platonism. The great dream seems to be that of mind-reading God, and the result is either Pythagoras (it's numbers!), or Plato (it's pure ideas!), or this (it's essences!). See D.H.Lawrence's poem on geranium and mignottes. |
| 12706 | Bodies need a soul (or something like it) to avoid being mere phenomena [Leibniz] |
| Full Idea: Every substance is indivisible and consequently every corporeal substance must have a soul or at least an entelechy which is analogous to the soul, since otherwise bodies would be no more than phenomena. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], G II 121), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 2 | |
| A reaction: There is a large gap between having 'a soul' and having something 'analogous to a soul'. I take the analogy to be merely as originators of action. Leibniz wants to add appetite and sensation to the Aristotelian forms (but knows this is dubious!). |
| 12906 | Truths about species are eternal or necessary, but individual truths concern what exists [Leibniz] |
| Full Idea: The concept of a species contains only eternal or necessary truths, whereas the concept of an individual contains, regarded as possible, what in fact exists or what is related to the existence of things and to time. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.06) | |
| A reaction: This seems to be what is behind the preference some have for kind-essences rather than individual essences. But the individual must be explained, as well as the kind. Not all tigers are identical. The two are, of course, compatible. |
| 22505 | The two right angles of a triangle necessitate that a quadrilateral has four [Aristotle] |
| Full Idea: If it is necessary that, if a triangle contains two right angles, that a quadrilateral has four, it is clear that the cause of this is that a triangle has two. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1222b31) | |
| A reaction: We would not normally use the word 'cause' for this, but 'necessitates' seems to fit, and I like the word 'determines' (because it can be both physical and abstract). An example of what I think of as an Aristotelian necessity maker. |
| 12904 | If varieties of myself can be conceived of as distinct from me, then they are not me [Leibniz] |
| Full Idea: I can as little conceive of different varieties of myself as of a circle whose diameters are not all of equal length. These variations would all be distinct one from another, and thus one of these varieties of myself would necessarily not be me. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.05.13) | |
| A reaction: This seems to be, at the very least, a rejection of any idea that I could have a 'counterpart'. It is unclear, though, where he would place a version of himself who learned a new language, or who might have had, but didn't have, a haircut. |
| 11981 | If someone's life went differently, then that would be another individual [Leibniz] |
| Full Idea: If the life of some person, or something went differently than it does, nothing would stop us from saying that it would be another person, or another possible universe which God had chosen. So truly it would be another individual. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.14) | |
| A reaction: Plantinga quotes this as an example of 'worldbound individuals'. This sort of remark leads to people saying that Leibniz believes all properties are essential, since they assume that his notion of essence is bound up with identity. But is it? |
| 22513 | Knowing is having knowledge; understanding is using knowledge [Aristotle] |
| Full Idea: Knowing and understanding is of two kinds, one having and the other using knowledge. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1225b11) | |
| A reaction: This corresponds to potential and actual. We wouldn't say that understanding must be used, but we have some sort of distinction between knowledge as pure and theoretical, and understanding enabling good application. |
| 12905 | I cannot think my non-existence, nor exist without being myself [Leibniz] |
| Full Idea: I am assured that as long as I think, I am myself. For I cannot think that I do not exist, nor exist so that I be not myself. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.05.13) | |
| A reaction: Elsewhere he qualifies the Cogito, but here he seems to straighforwardly endorse it. |
| 19334 | I can't just know myself to be a substance; I must distinguish myself from others, which is hard [Leibniz] |
| Full Idea: It is not enough for understanding the nature of myself, that I feel myself to be a thinking substance, one would have to form a distinct idea of what distinguishes me from all other possible minds; but of that I have only a confused experience. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14) | |
| A reaction: Not a criticism I have encountered before. Does he mean that I might be two minds, or might be a multitude of minds? It seems to be Hume's problem, that you are aware of experiences, but not of the substance that unites them. |
| 5033 | Nothing should be taken as certain without foundations [Leibniz] |
| Full Idea: Nothing should be taken as certain without foundations. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.04.30) | |
| A reaction: This might leave open the option, if you were a modern 'Fallibilist', that something might lack foundations, and so not be certain, and yet still qualify as 'knowledge'. That is my view. Knowledge resides somewhere between opinion and certainty. |
| 12913 | Nature is explained by mathematics and mechanism, but the laws rest on metaphysics [Leibniz] |
| Full Idea: One must always explain nature along mathematical and mechanical lines, provided one knows that the very principles or laws of mechanics or of force do not depend upon mathematical extension alone but upon certain metaphysical reasons. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14 X) | |
| A reaction: I like this, and may even use it as the epigraph of my masterwork. Recently Stephen Hawking (physicist) has been denigrating philosophy, but I am with Leibniz on this one. |
| 13089 | To fully conceive the subject is to explain the resulting predicates and events [Leibniz] |
| Full Idea: Even in the most contingent truths, there is always something to be conceived in the subject which serves to explain why this predicate or event pertains to it, or why this has happened rather than not. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.06) | |
| A reaction: The last bit, about containing what has happened, seems absurd, but the rest of it makes sense. It is just the Aristotelian essentialist view, that a full understanding of the inner subject will both explain and predict the surface properties. |
| 5034 | Mind is a thinking substance which can know God and eternal truths [Leibniz] |
| Full Idea: Minds are substances which think, and are capable of knowing God and of discovering eternal truths. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1687.10.09) | |
| A reaction: 'God' is there because the ability to grasp the ontological argument is seen as basic. Note a firm commitment to substance-dualism, and a rationalist commitment to the spotting of necessary truths as basic. He is not totally wrong. |
| 5032 | It seems probable that animals have souls, but not consciousness [Leibniz] |
| Full Idea: It appears probable that the brutes have souls, though they are without consciousness. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.12.08) | |
| A reaction: This will be a response to Descartes, who allowed animals sensations, but not minds or souls. Personally I cannot make head or tail of Leibniz's claim. What makes it "apparent" to him? |
| 23906 | Courage from spirit is natural and unconquerable, as seen in the young [Aristotle] |
| Full Idea: The courage of spirit is the most natural kind; for spirit is unconquerable, which is why the young are the best fighters. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1229a27) | |
| A reaction: [thumos, presumably, as in Plato] I suppose Aristotle knows better than me, but I suspect the young are just the quickest and strongest. I'd rather be led by someone with experience than by someone who is young. |
| 20204 | Whether the mind has parts is irrelevant, since it obviously has distinct capacities [Aristotle] |
| Full Idea: It makes no difference if the soul is divided into parts or lacks parts, as it certainly has distinct capacities. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1219b32), quoted by Linda Trinkaus Zagzebski - Virtues of the Mind II 3.1 | |
| A reaction: I take this to endorse my view that the mind-body problem is of limited interest to philosophers. The focus should be on what the mind does, not how it is constructed. But then I presume the latter issue is revealed by neuroscience. |
| 22506 | A man is the cause of what is within his power, and what he causes is in his power [Aristotle] |
| Full Idea: All those things that are in man's power either to do or not to do he himself is the cause of, and all those things that he is the cause of are in his own power. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1223a08) | |
| A reaction: This is the step which allows us to abandon free will, and replace it with the question of whether a person is the 'cause' of an action. Aristotle carefully delineates the criteria for when an action is within a person's power. Includes failures to act? |
| 22504 | Only a human being can be a starting point for an action [Aristotle] |
| Full Idea: A human being is a starting point of some actions, and he alone of animals; for of nothing else should we say that it acted. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1222b19) | |
| A reaction: It is a standard dogma that the idea of free will does not occur in Plato or Aristotle, but this looks awfully like it. I don't agree about animals. You watch them judging whether they can make a leap, and then doing it. |
| 5031 | Everything which happens is not necessary, but is certain after God chooses this universe [Leibniz] |
| Full Idea: It is not the case that everything which happens is necessary; rather, everything which happens is certain after God made choice of this possible universe, whose notion contains this series of things. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.05) | |
| A reaction: I think this distinction is best captured as 'metaphysical necessity' (Leibniz's 'necessity'), and 'natural necessity' (his 'certainty'). 'Certainty' seems a bad word, as it is either certain de dicto or de re. Is God certain, or is the thing certain? |
| 22510 | Some emotional states are too strong for human nature [Aristotle] |
| Full Idea: Many classify even love as involuntary, and certain cases of anger and certain natural states as being too strong for human nature; and we regard them as being pardonable, as being of such a nature as to be constrained by nature. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1225b20) | |
| A reaction: Blind terror would presumably count as another such state. An interesting aspect of Aristotle's picture - that human nature contains ingredients that are not part of a natural harmonious whole. |
| 23913 | Nearly all the good and bad states of character are concerned with feelings [Aristotle] |
| Full Idea: Pretty much all of the praiseworthy or blameworthy states concerned with character are either excesses, deficiencies, or medial conditions in feelings. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1233b16) | |
| A reaction: Suggests that the ideal state of character is the result of long and careful tuning of the feelings - insofar as we can control them. Presumably we can train feelings of hatred or compassion, by appropriate exposures. These states are NOT virtues. |
| 12911 | Concepts are what unite a proposition [Leibniz] |
| Full Idea: There must always be some basis for the connexion between the terms of a proposition, and it is to be found in their concepts. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14 X) | |
| A reaction: We face the problem that bothered Russell, of the unity of the proposition. We are also led to the question of HOW our concepts connect the parts of a proposition. Do concepts have valencies? Are they incomplete, as Frege suggests? |
| 23918 | Akrasia is the clash of two feelings - goodness and pleasure [Aristotle] |
| Full Idea: The discord between the good and the pleasant in one's feelings is lack of self-control. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1237a08) | |
| A reaction: A nice clear statement of his view, which opposes the view of Socrates that akrasia is a failure of reason or judgement. Goodness seems to be treated here as a feeling, which is unusual. |
| 22515 | Choice results when deliberation brings together an opinion with an inclination [Aristotle] |
| Full Idea: Choice is neither simply wish nor opinion, but opinion together with inclination, whenever as a result of deliberation they are brought to a conclusion. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1227a04) | |
| A reaction: This seems to be the earliest appearance of the belief-plus-desire theory of action, which is often associated with Hume. A choice does not necessarily result from having the inclination and the appropriate opinion. Laziness! |
| 22508 | Unlike in inanimate things, in animate things actions have more than one starting point [Aristotle] |
| Full Idea: In inanimate things the starting-point is single, in animate things there is more than one; for inclination and reason are not always in harmony. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1224a24) | |
| A reaction: It is important that this seems to include non-human animals. We see animals avoid something which they desire, presumably because they detect a danger. They may be conflicting desires, but it is rational to prioritise dangers. |
| 22514 | The deliberative part of the soul discerns explanatory causes [Aristotle] |
| Full Idea: That part of the soul is deliberative which is capable of discerning a cause: the reason for the sake of which - which is one of the causes - 'cause' being something because-of-which. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1226b26) | |
| A reaction: I take because-of-which to be the correct explanation. Since my model of practical reasoning is partly forensic detection, this seems right. Sherlock Holmes spots causes. |
| 22507 | An action is voluntary when it is accompanied by thought of some kind [Aristotle] |
| Full Idea: The voluntary consists in action accompanied by thought of some kind. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1224a06) | |
| A reaction: This is thought as opposed to inclination or choice. The controlled person [enkrateia] voluntarily acts against inclinations. The appropriate thought receives carefull analysis in NE 1109b30-1111b4. |
| 23319 | We are responsible if our actions reflect our motivation [Aristotle, by Frede,M] |
| Full Idea: For Aristotle, for us to be responsible for what we do, our action has to somehow reflect our motivation. | |
| From: report of Aristotle (Eudemian Ethics [c.333 BCE], 1224a07) by Michael Frede - A Free Will 2 | |
| A reaction: This sounds like 'mens rea' in law - meaning to do the thing you did. But we can obviously be responsible for things through neglect, for example. |
| 12925 | Beauty increases with familiarity [Leibniz] |
| Full Idea: The more one is familiar with things, the more beautiful one finds them. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1688.01.4/14) | |
| A reaction: This is always the reply given to those who say that science kills our sense of beauty. The first step in aesthetic life is certainly to really really pay attention to things. |
| 22512 | Acts are voluntary if done knowingly, by the agent, and in his power to avoid it [Aristotle] |
| Full Idea: Whatever a man does - not in ignorance, and through his own agency - when it is in his power not to do it, must be voluntary, and that is what voluntary is. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1225b08) | |
| A reaction: This is the conclusion of the Eudemian discussion of responsibility. This is a definition by necessary and sufficient conditions. How can you be sure that something is in your power not to do? |
| 22509 | What is natural for us is either there at birth, or appears by normal processes [Aristotle] |
| Full Idea: By these marks we distinguish what comes naturally: everything that is there straightaway as soon as something comes to be, and all that occurs to us if growth is allowed to proceed normally - such as greying hair, ageing, and the like. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1224b32) | |
| A reaction: The word 'normal' has to do a lot of work here. Presumably jaundice in a neonate is not included. Or later hereditary diseases. |
| 18230 | No one would choose life just for activities not done for their own sake [Aristotle] |
| Full Idea: If we put together all the things that are ....not done or undergone for their own sake ...no one would choose, in order to have them, to be alive rather than not. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1215), quoted by Christine M. Korsgaard - Aristotle and Kant on the Source of Value 8 'Finality' | |
| A reaction: Debatable. Roughly his question is whether you would rather be dead than be a slave, since slaves work for means, but have no ends. Aristotle would rather die, but those who surrendered in ancient battles preferred slavery. |
| 23909 | Wearing a shoe is its intrinsic use, and selling it (as a shoe) is its coincidental use [Aristotle] |
| Full Idea: There is intrinsic use of a possession, such as of a shoe or a cloak, and its coincidental use - not of course when using a shoe as a weight, but as, for example, selling it or hiring it out (for then a shoe is used as a shoe). | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1231b37) | |
| A reaction: This seems to need a third label, for using the shoe as a weight. 'Inessential use' perhaps, since the intrinsic use points towards the essential nature or function of the shoe. |
| 5870 | Everything seeks, not a single good, but its own separate good [Aristotle] |
| Full Idea: It is not true that everything that there is seeks some single good: each thing has an inclination for its own good, the eye for sight, the body for health, and so on. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1218a30) | |
| A reaction: Aristotle's pluralism. Elsewhere this pluralism arises from his function argument - that the good of each thing is the successful fulfilment of its function, which is different for each thing. This is basic to virtue theory, and has my approval. |
| 16764 | The soul conserves the body, as we see by its dissolution when the soul leaves [Toletus] |
| Full Idea: Every accident of a living thing, as well as all its organs and temperaments and its dispositions are conserved by the soul. We see this from experience, since when that soul recedes, all these dissolve and become corrupted. | |
| From: Franciscus Toletus (Commentary on 'De Anima' [1572], II.1.1), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 24.5 | |
| A reaction: A nice example of observing a phenemonon, but not being able to observe the dependence relation the right way round. Compare Descartes in Idea 16763. |
| 5877 | We judge people from their deeds because we cannot see their choices (which matter more) [Aristotle] |
| Full Idea: It is because it is not easy to discern what sort of choice it is that we are forced to judge from the deeds what sort of person someone is; the activity is more worth having, but the choice is commended more. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1228a15) | |
| A reaction: This shows why Aristotle is the most important opponent of consequentialism. It is hard to see how one could praise a self-interested deed simply because it benefited others. Greed is never good. |
| 5868 | Horses, birds and fish are not happy, lacking a divine aspect to their natures [Aristotle] |
| Full Idea: No horse or bird or fish is happy, nor any other thing that there is which does not have a share by its nature in the divine. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1217a26) | |
| A reaction: Pet owners will all feel their beloved companions have been insulted, but I agree with this. 'Happy' does not here mean 'in a state of pleasure'. A fully successful bird does little more than the four f's (feed, fornicate, flee, fight). |
| 12927 | Happiness is advancement towards perfection [Leibniz] |
| Full Idea: Happiness, or lasting contentment, consists of continual advancement towards a greater perfection. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1690.03.23) | |
| A reaction: To the modern mind this smacks of the sort of hubris to which only the religious mind can aspire, but it's still rather nice. The idea of grubby little mammals approaching perfection sounds wrong, but which other animal has even thought of perfection? |
| 5865 | Happiness involves three things, of which the greatest is either wisdom, virtue, or pleasure [Aristotle] |
| Full Idea: To be happy, and to live the fine and divinely-happy life, would seem to reside in three things above all, ..for some say that wisdom is the greatest good, others virtue, others pleasure. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1214a30) | |
| A reaction: Aristotle is well-known for his pluralist answer to this question: virtue is crucial, wisdom is perhaps the greatest of the virtues, and pleasure improves everything in life. |
| 5876 | Virtue is different from continence [Aristotle] |
| Full Idea: Virtue is different from continence. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1227b17) | |
| A reaction: Basic to Aristotle - in that continence leads to right action, but that is not enough for virtue, which requires inner harmony, reason, and pleasure in doing what is right. Hence Aristotle is quite distinct from deontological or consequentialist views. |
| 5872 | Excellence is the best state of anything (like a cloak) which has an employment or function [Aristotle] |
| Full Idea: Excellence is the best disposition, state or capacity of anything that has some employment or function; this is evident from induction. For example, a cloak has an excellence - and a certain function and employment also; its best state is its excellence. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1219a02) | |
| A reaction: 'Employment' will be an assigned function, and 'function' will be a natural or intrinsic function, I presume. This is a nice clear illustration of the fact that for Aristotle virtue runs continuously from people to cloaks. See Idea 1663, though. |
| 5874 | Character virtues (such as courage) are of the non-rational part, which follows the rational part [Aristotle] |
| Full Idea: The virtues of character belong to the part that is non-rational, but whose nature is to follow the rational part; we do not say what a man's character is like when we say that he is wise or clever, but when we say that he is gentle or daring. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1220a11) | |
| A reaction: In the Nichomachean Ethics it appears that good character is the 'harmony' between the two parts; here it sounds more like obedience. It seems to me that our rational part is a failure if it is not sensitive to the needs of the irrational part. |
| 22516 | Character is shown by what is or is not enjoyed, and virtue chooses the mean among them [Aristotle] |
| Full Idea: Virtue is that state of character which chooses the mean, relative to us, in things pleasant and unpleasant, all those in respect of which a man is said to have a certain sort of character according as he enjoys or suffers pain from them. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1227b08) | |
| A reaction: The 'mean' should be understood as what is appropriate, rather than the mere average. Strong anger, for example, is sometimes appropriate. Does Aristotle rule out wild laughter, or frenetic dancing? Is a state of ecstasy wicked? |
| 22517 | We judge character not by their actions, but by their reasons for actions [Aristotle] |
| Full Idea: It is from his choosing that we judge what sort of person someone is; that is, what that for whose sake he does something is, not what he does. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1228a03) | |
| A reaction: Not entirely true. It can be sufficient to reveal their character that a person does some particular thing, as novelists know. When Hud parks his car in her flowerbed, we don't need to enquire about his reason. But see 1228a16! |
| 5875 | Character (éthos) is developed from habit (ethos) [Aristotle] |
| Full Idea: Character (éthos), as the word itself indicates, is developed from habit (ethos). | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1220a36) | |
| A reaction: Aristotle goes in for dubious etymologies, but this one sounds quite significant, and supports his view that habit is central to virtue. We would lose nothing in English if we said 'what are her habits?' instead of 'what is her character?'. |
| 23914 | People sometimes exhibit both extremes together, but the mean is contrary to both of them [Aristotle] |
| Full Idea: The mean is more contrary to the extremes than the extremes are to each other, because it does not occur with either of them, whereas the extremes often occur with each other. People can be rash cowards, or wasteful in some things and generous in others. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1234a33) | |
| A reaction: This rather undermines the neat visual metaphor of a sliding scale, but gives a more accurate account of the mean. The diagram needs three dimensions, instead of two. |
| 23911 | Possessors of a virtue tend to despise what reason shows to be its opposite [Aristotle] |
| Full Idea: Each virtue makes its possessor tend to despise great things that are contrary to reason - for example, courage does this of dangers, …a temperate person of many pleasures, and a generous one of many sorts of wealth. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1232a37) | |
| A reaction: I like the observation that the generous tend to despise wealth, implying that those who love wealth tend to lack generosity. Christianity has encouraged us to reject the idea of despising anything - but that seems to iron out common sense values. |
| 23910 | Greatness of soul produces all the virtues - and vice versa [Aristotle] |
| Full Idea: All the virtues will follow along with greatness of soul, or it will follow along with all of them | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1232a36) | |
| A reaction: This is obviously similar in some respects to Nietzsche's 'higher' man, though that suggests greater independence, rather than being an ideal citizen. |
| 23908 | If someone just looks at or listens to beautiful things, they would not be thought intemperate [Aristotle] |
| Full Idea: If someone looks at a beautiful statue, or horse, or human being, or listens to someone singing …just to look at or listen to beautiful things, he would not be thought to be intemperate, any more than those beguiled by the Sirens would. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1230b31) | |
| A reaction: He says that intemperance mainly concerns taste and touch, rather than mere looking or listening. I think obsessive collectors of beautiful objects might drift into intemperance. |
| 23905 | Courage follows reason, which tells us to choose what is noble [Aristotle] |
| Full Idea: Courage is a following of reason, and reason orders us to choose what is noble. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1229a01) | |
| A reaction: This sounds right to me. Courage, in all sorts of contexts, seems to arise in people who sustain their focus on what is the right thing to do. |
| 23912 | Honour depends on what it is for, and whether it is bestowed by worthy people [Aristotle] |
| Full Idea: It makes a difference whether the honour comes from many random people or from those worthy of note, and again so does by whom and for what the honor is conferred. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1232b18) | |
| A reaction: He tends to play down honour because of its relativism, but this quotation implies that if an honour was bestowed by the worthy, for something of agreed high value, then it would be at quite a different level from mere popular esteem. Celebrity v peerage? |
| 5871 | Goods in the soul are more worthy than those outside it, as everybody wants them [Aristotle] |
| Full Idea: All goods are either in the soul or outside it, and it is those in the soul that are more worthy of choice; for wisdom, virtue and pleasure are in the soul, and some or all of these seem to be an end for everyone. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1218b34) | |
| A reaction: An interesting reason for this assertion - that it is true because everybody agrees on it. See Idea 95. I would think that he might claim that our soul is our essence, whereas external goods pander to the non-essential in us. |
| 23920 | Decent people can be friends with base people [Aristotle] |
| Full Idea: It is possible for a decent person to be friends with a base one. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1238b01) | |
| A reaction: This is on the basis of being useful, or of having something in common. Presumably friendship can come in degrees, as well as being of different kinds. Even the finest people can differ a lot, and only have a limited friendship. |
| 23919 | Friendship cannot be immediate; it takes time, and needs testing [Aristotle] |
| Full Idea: Just as if people wish to be healthy they do not become healthy, so if they wish to be friends they are not immediately in fact friends. …[1237b40] For a friend is not to be had without a test or in a single day, but needs time. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1237b21) | |
| A reaction: The voice of experience, I think. Obviously trust is basic, and it would be unwise to trust a possible friend on the first day. Since politics aims at friendship, I presume the support of the rule of law helps to achieve trust. |
| 23915 | The main function of politics is to produce friendship [Aristotle] |
| Full Idea: It seems to be most of all the function of politics to produce friendship. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1245b22) | |
| A reaction: Lovely! Most people would probably cite wealth and security as the main aims. This function seems to require quite a high degree of equality, though Aristotle doesn't think it essential. |
| 23916 | The best cure for mutual injustice is friendship [Aristotle] |
| Full Idea: If one wishes to make it so that people do not commit injustices to each other, it is enough to make them friends; for true friends do not commit injustice. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1245b28) | |
| A reaction: This, along with Idea 23915, offers a beautiful vision of what a society should try to achieve. There can be duplicitous apparent friends, but on the whole the best way to cure unjust relations is friendship. Imagine Jews and Arabs being friends (2023). |
| 5866 | It is folly not to order one's life around some end [Aristotle] |
| Full Idea: Not to have ordered one's life in relation to some end is a mark of extreme folly. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1214b10) | |
| A reaction: A most interesting claim, not found in the Nichomachean Ethics. There the teleology is descriptive, but here it is prescriptive. It is tempting to rebel against Aristotle's injuncture. He was a driven workaholic. Why not float through life like gossamer? |
| 5878 | Eyes could be used for a natural purpose, or for unnatural seeing, or for a non-seeing activity [Aristotle] |
| Full Idea: One might wonder if it is possible to use each thing both for its natural purpose and otherwise - and that as itself or incidentally. E.g. twisting an eye so that one thing appears two, but also using an eye as something to sell or eat. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1246a26) | |
| A reaction: The important idea here is the core notion that there is a 'natural' purpose. Sceptics might say that all purposes derive from how a mind wishes to use something; otherwise there would be processes, but no 'functions' or 'purposes'. |
| 5873 | Each thing's function is its end [Aristotle] |
| Full Idea: Each thing's function is its end. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1219a08) | |
| A reaction: Function and end are not the same, but this confirms how closely related they are for Aristotle. Can an inanimate object have an end, without having any apparent function? Could I construct a set of cogwheels which each had a function, but no end? |
| 15955 | I think the corpuscular theory, rather than forms or qualities, best explains particular phenomena [Leibniz] |
| Full Idea: I still subscribe fully to the corpuscular theory in the explanation of particular phenomena; in this sphere it is of no value to speak of forms or qualities. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 14.07.1686) | |
| A reaction: I am puzzled by Garber's summary in Idea 12728, and a bit unclear on Leibniz's views on atoms. More needed. |
| 12907 | Each possible world contains its own laws, reflected in the possible individuals of that world [Leibniz] |
| Full Idea: As there exist an infinite number of possible worlds, there exists also an infinite number of laws, some peculiar to one world, some to another, and each individual of any one world contains in the concept of him the laws of his world. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.06) | |
| A reaction: Since Leibniz's metaphysics is thoroughly God-driven, he will obviously allow God to create any laws He wishes, and hence scientific essentialism seems to be rejected, even though Leibniz is keen on essences. Unless the stuff is different... |
| 12924 | Motion alone is relative, but force is real, and establishes its subject [Leibniz] |
| Full Idea: Motion in itself separated from force is merely relative, and one cannot establish its subject. But force is something real and absolute. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1688.01.4/14) | |
| A reaction: The striking phrase here is that force enables us to 'establish its subject'. That is, force is at the heart of reality, and hence, through causal relations, individuates objects. That's how I read it. |
| 12909 | Everything, even miracles, belongs to order [Leibniz] |
| Full Idea: Everything, even miracles, belongs to order. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14 X) | |
| A reaction: This is very reminiscent of Plato, for whom there was no more deeply held belief than that the cosmos is essentially orderly. Coincidences are a nice problem, if they are events with no cause. |
| 5030 | Miracles are extraordinary operations by God, but are nevertheless part of his design [Leibniz] |
| Full Idea: Miracles, or the extraordinary operations of God, none the less belong within the general order; they are in conformity with the principal designs of God, and consequently are included in the notion of this universe, which is the result of those designs. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.05) | |
| A reaction: Some philosophers just make up things to suit themselves. What possible grounds can he have for claiming this? At best this is tautological, saying that, by definition, if anything at all happens, it must be part of God's design. Move on to Hume… |
| 12912 | Immortality without memory is useless [Leibniz] |
| Full Idea: Immortality without memory would be useless. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.07.4/14 X) | |
| A reaction: I would say that having a mind of any sort needs memory. The question for immortality is whether it extends back to human life. See 'Wuthering Heights' (c. p90) for someone who remembers Earth as so superior to paradise that they long to return there. |
| 12917 | The soul is indestructible and always self-aware [Leibniz] |
| Full Idea: Not only is the soul indestructible, but it always knows itself and remains self-conscious. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.11) | |
| A reaction: Personally I am not even self-aware during much of my sleeping hours, and I would say that I cease to be self-aware if I am totally absorbed in something on which I concentrate. |
| 12918 | Animals have souls, but lack consciousness [Leibniz] |
| Full Idea: It appears probable that animals have souls although they lack consciousness. | |
| From: Gottfried Leibniz (Letters to Antoine Arnauld [1686], 1686.11) | |
| A reaction: Personally I would say that they lack souls but have consciousness, but then I am in no better position to know the answer than Leibniz was. Arnauld asks what would happen to the souls of 100,000 silkworms if they caught fire! |
