80 ideas
| 21955 | My dogmatic slumber was first interrupted by David Hume [Kant] |
| Full Idea: I freely admit that remembrance of David Hume was the very thing that many years ago first interrupted my dogmatic slumber. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 4:260), quoted by A.W. Moore - The Evolution of Modern Metaphysics 5.2 | |
| A reaction: A famous declaration. He realised that he had the answer the many scepticisms of Hume, and accept his emphasis on the need for experience. |
| 12124 | Metaphysics is the best knowledge, because it is the simplest [Bacon] |
| Full Idea: That knowledge is worthiest which is charged with least multiplicity, which appeareth to be metaphysic | |
| From: Francis Bacon (The Advancement of Learning [1605], II.VII.6) | |
| A reaction: A surprising view, coming from the father of modern science, but essentially correct. Obviously metaphysics aspires to avoid multiplicity, but it is riddled not only with complexity in its researches, but massive uncertainties. |
| 16931 | Metaphysics is generating a priori knowledge by intuition and concepts, leading to the synthetic [Kant] |
| Full Idea: The generation of knowledge a priori, both according to intuition and according to concepts, and finally the generation of synthetic propositions a priori in philosophical knowledge, constitutes the essential content of metaphysics. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 274) | |
| A reaction: By 'concepts' he implies mere analytic thought, so 'intuition' is where the exciting bit is, and that is rather vague. |
| 12123 | Natural history supports physical knowledge, which supports metaphysical knowledge [Bacon] |
| Full Idea: Knowledges are as pyramides, whereof history is the basis. So of natural philosophy, the basis is natural history, the stage next the basis is physic; the stage next the vertical point is metaphysic. | |
| From: Francis Bacon (The Advancement of Learning [1605], II.VII.6) | |
| A reaction: The father of modern science keeps a place for metaphysics, as the most abstract level above the physical sciences. I would say he is right. It leads to my own slogan: science is the servant of philosophy. |
| 12119 | Physics studies transitory matter; metaphysics what is abstracted and necessary [Bacon] |
| Full Idea: Physic should contemplate that which is inherent in matter, and therefore transitory; and metaphysic that which is abstracted and fixed | |
| From: Francis Bacon (The Advancement of Learning [1605], II.VII.3) | |
| A reaction: He cites the ancients for this view, with which he agrees. One could do worse than hang onto metaphysics as the study of necessities, but must then face the attacks of the Quineans - that knowledge of necessities is beyond us. |
| 12120 | Physics is of material and efficient causes, metaphysics of formal and final causes [Bacon] |
| Full Idea: Physic inquireth and handleth the material and efficient causes; and metaphysic handleth the formal and final causes. | |
| From: Francis Bacon (The Advancement of Learning [1605], II.VII.3) | |
| A reaction: Compare Idea 12119. This divides up Aristotle's famous Four Causes (or Explanations), outlined in 'Physics' II.3. The concept of 'matter', and the nature of 'cause' seem to me to fall with the purview of metaphysics. Interesting, though. |
| 19767 | Reason leads to prudent selfishness, which overrules natural compassion [Rousseau] |
| Full Idea: Reason is what engenders egocentrism ...turns man in upon himself ...and separates him from all that troubles him and afflicts him. Philosophy is what ...moves him to say at the sight of a suffering man 'Perish if you will; I am safe and sound'. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: He goes on to observe that fights in the marketplace are stopped by women, while the philosophers have all run away! This thinking leads to the sentimental movement, and then to romanticism. |
| 16918 | Mathematics cannot proceed just by the analysis of concepts [Kant] |
| Full Idea: Mathematics cannot proceed analytically, namely by analysis of concepts, but only synthetically. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 284) | |
| A reaction: I'm with Kant insofar as I take mathematics to be about the world, no matter how rarefied and 'abstract' it may become. |
| 16930 | Geometry is not analytic, because a line's being 'straight' is a quality [Kant] |
| Full Idea: No principle of pure geometry is analytic. That the straight line beween two points is the shortest is a synthetic proposition. For my concept of straight contains nothing of quantity but only of quality. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 269) | |
| A reaction: I'm not sure what his authority is for calling straightness a quality rather than a quantity, given that it can be expressed quantitatively. It is a very nice example for focusing our questions about the nature of geometry. I can't decide. |
| 16919 | Geometry rests on our intuition of space [Kant] |
| Full Idea: Geometry is grounded on the pure intuition of space. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 284) | |
| A reaction: I have the impression that recent thinkers are coming round to this idea, having attempted purely algebraic or logical accounts of geometry. |
| 16920 | Numbers are formed by addition of units in time [Kant] |
| Full Idea: Arithmetic forms its own concepts of numbers by successive addition of units in time. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 284) | |
| A reaction: It is hard to imagine any modern philosopher of mathematics embracing this idea. It sounds as if Kant thinks counting is the foundation of arithmetic, which I quite like. |
| 16929 | 7+5 = 12 is not analytic, because no analysis of 7+5 will reveal the concept of 12 [Kant] |
| Full Idea: The concept of twelve is in no way already thought by merely thinking the unification of seven and five, and though I analyse my concept of such a possible sum as long as I please, I shall never find twelve in it. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 269) | |
| A reaction: It might be more plausible to claim that an analysis of 12 would reveal the concept of 7+5. Doesn't the concept of two collections of objects contain the concept of their combined cardinality? |
| 16910 | Mathematics can only start from an a priori intuition which is not empirical but pure [Kant] |
| Full Idea: We find that all mathematical knowledge has this peculiarity, that it must first exhibit its concept in intuition, and do so a priori, in an intuition that is not empirical but pure. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 281) | |
| A reaction: Later thinkers had grave doubts about this Kantian 'intuition', even if they though maths was known a priori. Personally I am increasing fan of rational intuition, even if I am not sure how to discern whether it is rational on any occasion. |
| 16917 | All necessary mathematical judgements are based on intuitions of space and time [Kant] |
| Full Idea: Space and time are the two intuitions on which pure mathematics grounds all its cognitions and judgements that present themselves as at once apodictic and necessary. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 284) | |
| A reaction: This unlikely proposal seems to be based on the idea that mathematics must arise from the basic categories of our intuition, and these two are the best candidates he can find. I would say that high-level generality is the basis of mathematics. |
| 16928 | Mathematics cannot be empirical because it is necessary, and that has to be a priori [Kant] |
| Full Idea: Mathematical propositions are always judgements a priori, and not empirical, because they carry with them necessity, which cannot be taken from experience. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 268) | |
| A reaction: Presumably there are necessities in the physical world, and we might discern them by generalising about that world, so that mathematics is (by a tortuous abstract route) a posteriori necessary? Just a thought… |
| 11833 | The substance, once the predicates are removed, remains unknown to us [Kant] |
| Full Idea: It has long since been noticed that in all substances the subject proper, namely what is left over after all the accidents (as predicates) have been taken away and hence the 'substantial' itself, is unknown to us. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 333) | |
| A reaction: This is the terminus of the process of abstraction (though Wiggins says such removal of predicates is a myth). Kant is facing the problem of the bare substratum, or haecceity. |
| 19757 | No one would bother to reason, and try to know things, without a desire for enjoyment [Rousseau] |
| Full Idea: We seek to know only because we desire to find enjoyment; and it is impossible to conceive why someon who had neither desires nor fears would go to the bother reasoning. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: This appears to be an echo of Hume's pessimism about the autonomy of reason. This downgrading of reason is a striking feature of the Enlightenment, which presumably culminates in the romantic movement. |
| 21957 | 'Transcendental' concerns how we know, rather than what we know [Kant] |
| Full Idea: The word 'transcendental' signifies not a relation of our cognition to things, but only to the faculty of cognition. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 4:293), quoted by A.W. Moore - The Evolution of Modern Metaphysics 5.4 | |
| A reaction: This is the annoying abduction of a word which is very useful in metaphysical contexts. |
| 16923 | I admit there are bodies outside us [Kant] |
| Full Idea: I do indeed admit that there are bodies outside us. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 289 n.II) | |
| A reaction: This is the end of a passage in which Kant very explicitly denies being an idealist. Of course, he says we can only know the representations of things, and not how they are in themselves. |
| 21441 | 'Transcendental' is not beyond experience, but a prerequisite of experience [Kant] |
| Full Idea: The word 'transcendental' does not mean something that goes beyond all experience, but something which, though it precedes (a priori) all experience, is destined only to make knowledge by experience possible. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 373 n) | |
| A reaction: One of two explanations by Kant of 'transcendental', picked out by Sebastian Gardner. I think the word 'prerequisite' covers the idea nicely, using a normal English word. Or am I missing something? |
| 16916 | A priori synthetic knowledge is only of appearances, not of things in themselves [Kant] |
| Full Idea: Through intuition we can only know objects as they appear to us (to our senses), not as they may be in themselves; and this presupposition is absolutely necessary if synthetic propositions a priori are to be granted as possible. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 283) | |
| A reaction: This idea is basic to understanding Kant, and especially his claim that arithmetic is a priori synthetic. |
| 16915 | A priori intuitions can only concern the objects of our senses [Kant] |
| Full Idea: Intuitions which are possible a priori can never concern any other things than objects of our senses. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 283) | |
| A reaction: Given the Kantian idea that what is known a priori will also be necessary, we might have had great hopes for big-time metaphysics, but this idea cuts it down to size. Personally, I don't think we are totally imprisoned in the phenomena. |
| 16914 | A priori intuition of objects is only possible by containing the form of my sensibility [Kant] |
| Full Idea: The only way for my intuition to precede the reality of the object and take place as knowledge a priori is if it contains nothing else than the form of sensibility which in me as subject precedes all real impressions through which I'm affected by objects. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 283) | |
| A reaction: This may be the single most famous idea in Kant. I'm not really a Kantian, but this is a powerful idea, the culmination of Descartes' proposal to start philosophy by looking at ourselves. No subsequent thinking can ignore the idea. |
| 21447 | I can make no sense of the red experience being similar to the quality in the object [Kant] |
| Full Idea: I can make little sense of the assertion that the sensation of red is similar to the property of the vermilion [cinnabar] which excites this sensation in me. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 290) | |
| A reaction: A sensible remark. In Kant's case it is probably a part of his scepticism that his intuitions reveal anything directly about reality. Locke seems to have thought (reasonably enough) that the experience contains some sort of valid information. |
| 16924 | I count the primary features of things (as well as the secondary ones) as mere appearances [Kant] |
| Full Idea: I also count as mere appearances, in addition to [heat, colour, taste], the remaining qualities of bodies which are called primariae, extension, place, and space in general, with all that depends on it (impenetrability or materiality, shape etc.). | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 289 n.II) | |
| A reaction: He sides with Berkeley and Hume against Locke and Boyle. He denies being an idealist (Idea 16923), so it seems to me that Kant might be described as a 'phenomenalist'. |
| 16913 | I can't intuit a present thing in itself, because the properties can't enter my representations [Kant] |
| Full Idea: It seems inconceivable how the intuition of a thing that is present should make me know it as it is in itself, for its properties cannot migrate into my faculty of representation. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 282) | |
| A reaction: One might compare this with Locke's distinction of primary and secondary, where the primary properties seem to 'migrate into my faculty of representation', but the secondary ones fail to do so. I think I prefer Locke. This idea threatens idealism. |
| 12121 | We don't assume there is no land, because we can only see sea [Bacon] |
| Full Idea: They are ill discoverers that think there is no land, when they can see nothing but sea. | |
| From: Francis Bacon (The Advancement of Learning [1605], II.VII.5) | |
| A reaction: Just the sort of pithy remark for which Bacon is famous. It is an obvious point, but a nice corrective to anyone who wants to apply empirical principles in a rather gormless way. |
| 16925 | Appearance gives truth, as long as it is only used within experience [Kant] |
| Full Idea: Appearance brings forth truth so long as it is used in experience, but as soon as it goes beyond the boundary of experience and becomes transcendent, it brings forth nothing but illusion. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 292 n.III) | |
| A reaction: This is the nearest I have found to Kant declaring for empiricism. It sounds something like direct realism, if experience itself can bring forth truth. |
| 16911 | Intuition is a representation that depends on the presence of the object [Kant] |
| Full Idea: Intuition is a representation, such as would depend on the presence of the object. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 282) | |
| A reaction: This is a distinctively Kantian view of intuition, which arises through particulars, rather than the direct apprehension of generalities. |
| 12117 | Science moves up and down between inventions of causes, and experiments [Bacon] |
| Full Idea: All true and fruitful natural philosophy hath a double scale or ladder, ascendent and descendent, ascending from experiments to the invention of causes, and descending from causes to the invention of new experiments. | |
| From: Francis Bacon (The Advancement of Learning [1605], II.VII.1) | |
| A reaction: After several hundred years, I doubt whether anyone can come up with a better account of scientific method than Bacon's. |
| 12127 | Many different theories will fit the observed facts [Bacon] |
| Full Idea: The ordinary face and view of experience is many times satisfied by several theories and philosophies. | |
| From: Francis Bacon (The Advancement of Learning [1605], II.VIII.5) | |
| A reaction: He gives as his example that the Copernican system and the Ptolemaic system both seem to satisfy all the facts. He wrote in 1605, just before Galileo's telescope. His point is regularly made in modern discussions. In this case, he was wrong! |
| 12126 | People love (unfortunately) extreme generality, rather than particular knowledge [Bacon] |
| Full Idea: It is the nature of the mind of man (to the extreme prejudice of knowledge) to delight in the spacious liberty of generalities, as in a champaign region, and not in the inclosures of particularity. | |
| From: Francis Bacon (The Advancement of Learning [1605], II.VIII.1) | |
| A reaction: I have to plead guilty to this myself. He may have pinpointed the key motivation behind philosophy. We all want to know things, as Aristotle said, but some of us want the broad brush, and others want the fine detail. |
| 19760 | General ideas are purely intellectual; imagining them is immediately particular [Rousseau] |
| Full Idea: Every general idea is purely intellectual. The least involvement of the imagination thereupon makes the idea particular. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: This thought is in Berkeley, who seemed to think that general ideas were impossible, because imagination was always required. Rousseau is certainly an improvement on that. |
| 19759 | Only words can introduce general ideas into the mind [Rousseau] |
| Full Idea: General ideas can be introduced into the mind only with the aid of words. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: Hm. How did humanity manage to invent general words. Do animals not have general thoughts, e.g. about food, shelter, predators? Roussea goes on to deny that monkeys see nuts as a 'type' of fruit. |
| 16912 | Some concepts can be made a priori, which are general thoughts of objects, like quantity or cause [Kant] |
| Full Idea: Concepts are of such a nature that we can make some of them ourselves a priori, without standing in any immediate relation to the object; namely concepts that contain the thought of an object in general, such as quantity or cause. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 282) | |
| A reaction: 'Quantity' seems to be the scholastic idea, of something having a magnitude (a big pebble, not six pebbles). |
| 19758 | Language may aid thinking, but powerful thought was needed to produce language [Rousseau] |
| Full Idea: If men needed speech in order to learn to think, they had a still greater need for knowing how to think in order to discover the art of speaking. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: I take language to be a consequence of the emergence of meta-thought in humanity, so I thoroughly endorse Rousseau's view. The idea that rationality, and even consciousness, are mainly facilitated by language strikes me as quite wrong. |
| 16926 | Analytic judgements say clearly what was in the concept of the subject [Kant] |
| Full Idea: Analytic judgements say nothing in the predicate that was not already thought in the concept of the subject, though not so clearly and with the same consciousness. If I say all bodies are extended, I have not amplified my concept of body in the least. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 266) | |
| A reaction: If I say all bodies are made of atoms, have I extended my concept of 'body'? It would come as a sensational revelation for Aristotle, but it now seems analytic. |
| 16927 | Analytic judgement rests on contradiction, since the predicate cannot be denied of the subject [Kant] |
| Full Idea: Analytic judgements rest wholly on the principle of contradiction, …because the predicate cannot be denied of the subject without contradiction. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 267) | |
| A reaction: So if I say 'gold has atomic number 79', that is a (Kantian) analytic statement? This is the view of sceptics about Kripke's a posteriori necessity. …a few lines later Kant gives 'gold is a yellow metal' as an example. |
| 19773 | Without love, what use is beauty? [Rousseau] |
| Full Idea: Where there is no love, what use is beauty? | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: Rousseau seems to be thinking of sexual attractiveness, but the aphorism seems to have universal application. |
| 19769 | Rational morality is OK for brainy people, but ordinary life can't rely on that [Rousseau] |
| Full Idea: Although it might be appropriate for Socrates and minds of his stature to acquire virtue through reason, the human race would long ago have ceased to exist, if its preservation had depended solely on the reasonings of its members. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: He takes our natural compassion to be the basis of morality. Hume combines that with a natural social prudence. Apes live successfully together in groups, without a Socrates. See MacIntyre on the failure of reasoned morality. |
| 19752 | If we should not mistreat humans, it is mainly because of sentience, not rationality [Rousseau] |
| Full Idea: If I am obliged not to do any harm to my fellow man, it is less because he is a rational being than because he is a sentient being. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Pref) | |
| A reaction: How should sentience and rationality be weighted here? Kant demands instrinsic respect for beings on the grounds of their rationality. What could ever justify doing needless harm to anything? An open goal for virtue theory here. |
| 19768 | The better Golden Rule is 'do good for yourself without harming others' [Rousseau] |
| Full Idea: Instead of the sublime maxim of reasoned justice 'Do unto others as you would have them do unto you', pity inspires a less perfect but perhaps more useful one: 'Do what is good for you with as little harm as possible to others'. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: His revised maxim is like J.S. Mill's formula for liberalism. The first maxim seems more contractarian, the second more utilitarian. |
| 19766 | The fact that we weep (e.g. in theatres) shows that we are naturally compassionate [Rousseau] |
| Full Idea: Every day one sees in our theatres someone affected and weeping at the ills of some unfortunate person ...Nature, in giving men tears, bears witness that she gave the human race the softest hearts. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: Lovely. Of course, tears in infants are for their own misfortunes, but adults more commonly weep over the sufferings of others. But we somewhat laugh at people who easily cry over dramas about suffering. |
| 19756 | Humans are less distinguished from other animals by understanding, than by being free agents [Rousseau] |
| Full Idea: It is not so much understanding which causes the specific distinction of man from all other animals as it is his being a free agent. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: I'm not sure how deep Rousseau takes 'free' to go. Having little enthusiasm for free will, I would say that we are distinguished by the complexity of our decision making. But I attribute that to meta-thought, the mark of humanity. |
| 19755 | Most human ills are self-inflicted; the simple, solitary, regular natural life is good [Rousseau] |
| Full Idea: Most of our ills are of our own making, and we could have avoided nearly all of them by preserving the simple, regular and solitary lifestyle prescribed to us by nature. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: It is important that he is not really disagreeing with Hobbes's pessimistic view of natural life as 'nasty'. Rousseau attributes that to a later stage, when people are ineptly beginning to emerge from the state of nature. I'm an optimist here. |
| 19762 | Is language a pre-requisite for society, or might it emerge afterwards? [Rousseau] |
| Full Idea: Which was more necessary: an already formed society for the invention of languages, or an already invented language for the establishment of society? | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: Rousseau declines to attempt an answer. Ants and bees seem to do well, but have some means of communication. Ape colonies are quite sophisticated. |
| 19763 | I doubt whether a savage person ever complains of life, or considers suicide [Rousseau] |
| Full Idea: I ask if anyone has ever heard tell of a savage who was living in liberty ever dreaming of complaining about his life and of killing himself. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: Rousseau's state of nature is much too remote from any current tribal life for this to be tested. It is a nice speculation. Do apes ever attempt suicide? |
| 19765 | Savages avoid evil because they are calm, and never think of it (not because they know goodness) [Rousseau] |
| Full Idea: We could say that savages are not evil because they do not know what is good; for it is neither enlightenment nor legal restraint, but the calm of the passions and the ignorance of vice which prevents them from doing evil. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: Suggests one of my favourite ideas (Idea 519). While his hopes for savages and the state of nature may be optimistic, the idea that you won't do evil if it never crosses your mind (and it won't if you are a calm person) is very powerful. |
| 19779 | Primitive man was very gentle [Rousseau] |
| Full Idea: Nothing is so gentle as man in his primitive state. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II) | |
| A reaction: This summarises Rousseau's view of the earliest stage of mankind, when there was little rivalry, and little motivation or opportunity for viciousness. |
| 19771 | Savage men quietly pursue desires, without the havoc of modern frenzied imagination [Rousseau] |
| Full Idea: Imagination, which wreaks so much havoc among us, does not speak to savage hearts; each man peacefully awaits the impetus of nature, gives himself over to it without choice, and with more pleasure than frenzy; then all desire is snuffed out. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: Interesting to identify imagination as a source of trouble. The idea that the savage lacks imagination seems implausible. Better to say that modern imagination has been poisoned by competition. |
| 19778 | Leisure led to envy, inequality, vice and revenge, which we now see in savages [Rousseau] |
| Full Idea: People developed leisure pursuits, and wanted esteem, which was the first step towards inequality, and at the same time towards vice. Vanity, contempt, shame and envy were born, and acts of revenge. This is the stage of savage people we know of. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II) | |
| A reaction: [very compressed] This is important in understanding Rousseau, because his happier 'state of nature' is prior to what is described here, which is the violent warlike state which impressed Hobbes. |
| 19751 | Our two starting principles are concern for self-interest, and compassion for others [Rousseau] |
| Full Idea: One principle prior to reason makes us ardently interested in our well-being and self-preservation; the other inspires a natural repugnance to seeing any sentient being, especially our fellow man, perish or suffer. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Pref) | |
| A reaction: This is strikingly like Hume's nascent utilitarianism. These two principles are the key to Rousseau's vision of the state of nature, from which the union around a general will leads to the formation of a state. Note that animals get included here. |
| 19774 | A savage can steal fruit or a home, but there is no means of achieving obedience [Rousseau] |
| Full Idea: A savage man could well lay hold of the fruit another has gathered, the cave that served as his shelter. But how will he ever succeed in making himself obeyed? What can be the chain of dependence among men who possess nothing? | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: You'd certainly need language to express an enduring threat, like excluding someone from all of the local caves. You need to be able to say 'I'll be back', which animals can't say. Huge muscular men must have dominated in some way. |
| 19772 | In a state of nature people are much more equal; it is society which increases inequalities [Rousseau] |
| Full Idea: There must be much less difference between one man and another in the state of nature than in that of society, and natural inequality must increase in the human species through inequality occasioned by social institutions. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: This is the main idea of his essay - the answer to the question set by the essay prize. Slavery is common in fairly basic societies, but that is at a much more advanced stage than Rousseau is thinking of. It's hard to disagree with him. |
| 19789 | It is against nature for children to rule old men, fools to rule the wise, and the rich to hog resources [Rousseau] |
| Full Idea: It is obviously contrary to the law of nature, however it is defined, for a child to command an old man, for an imbecile to lead a wise man, and for a handful of people to gorge themselves on superfluities while the starving multitude lack necessities. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II) | |
| A reaction: I wonder if gregarious animals ever starve to death during a time of plenty, because of social exclusion? I bet this idea was quoted widely in 1780s Paris. The massive inequality is not just nasty, but 'contrary to the law of nature'. |
| 19787 | People accept the right to be commanded, because they themselves wish to command [Rousseau] |
| Full Idea: Citizens allow themselves to be oppressed only insofar as they are driven by blind ambition; ...they consent to wear chains in order to be able to give them in turn to others. It is difficult to reduce to obedience someone who does not wish to command. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II) | |
| A reaction: Beautiful. This produces what I call the 'military model of management', where people love tree diagrams showing chains of command, and their place in the hierarchy. Life becomes 'either give orders, or obey'. I like democratic teams. |
| 19780 | We seem to have made individual progress since savagery, but actually the species has decayed [Rousseau] |
| Full Idea: Evidence confirms that the savage state is the youth of the world, and all subsequent progress has been in appearance so many steps toward the perfection of the individual, and in fact toward the decay of the species. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II) | |
| A reaction: This strikes me as an attack on the new rising philosophy of liberalism, and a plea for communitarianism. We should judge humanity as a whole, and not just look at some individual lives which seem to be going well. |
| 19747 | Revolutionaries usually confuse liberty with total freedom, and end up with heavier chains [Rousseau] |
| Full Idea: If people try to shake off a yoke, they put more distance between themselves and liberty, because in mistaking for liberty an unbridled licence which is its opposite, their revolutions usually deliver them over to seducers who make their chains heavier. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Intro letter) | |
| A reaction: This 'Animal Farm' thought was presumably ignored in 1789 and 1917. There must be basic rules for revolutionaries, of which priorities they must never drop from sight, and which priorities are dangerous and misleading. |
| 19748 | Plebiscites are bad, because they exclude the leaders from crucial decisions [Rousseau] |
| Full Idea: I would not approve of plebiscites like those of the Romans where the state's leaders and those most interested in its preservation were excluded from the deliberations on which its safety often depended. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Intro letter) | |
| A reaction: I wish David Cameron had read this before 2016. This is exactly what happened with the Brexit referendum, where the people voted for an action entirely opposed to the preference of the majority of their elected representatives. Chaos ensued. |
| 19749 | In a direct democracy, only the leaders should be able to propose new laws [Rousseau] |
| Full Idea: In order to stop ...the dangerous innovations that finally ruined Athens, no one would have the power to propose new laws according to his fancy; this right belongs exclusively to the magistrates. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Intro letter) | |
| A reaction: Aristotle says (somewhere!) that control of the agenda for meetings is the key issue in democracies. I assume any citizen can propose a law, but only a magistrate can put it on the agenda. Maybe a separate 'citizen's committee' could filter suggestions. |
| 19775 | People must be made dependent before they can be enslaved [Rousseau] |
| Full Idea: It is impossible to enslave a man without having first put him in the position of being incapable of doing without another. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: Ah yes. The key to running a slave plantation is not the threat of violence, but control of the shelter and food supply. |
| 19784 | Enslaved peoples often boast of their condition, calling it a state of 'peace' [Rousseau] |
| Full Idea: Enslaved peoples do nothing but boast of the peace and tranquillity they enjoy in their chains and they give the name 'peace' to the most miserable slavery. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II) | |
| A reaction: It seems to be a sad truth that enslaved peoples are less upset about their condition than outside observers are, especially in modern times, where slavery is usually deemed unacceptable. Slavery might be the best you can hope for. |
| 19785 | If the child of a slave woman is born a slave, then a man is not born a man [Rousseau] |
| Full Idea: The jurists who have gravely pronounced that the child of a slave woman is born a slave, have decided, in other words, that a man is not born a man. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II) | |
| A reaction: The hidden premise of this enthymeme is that man is born free. A key issue of liberalism is the status of children. Are the children of religious believers automatically members of that sect? Can I be born a West Ham supporter? |
| 19746 | Like rich food, liberty can ruin people who are too weak to cope with it [Rousseau] |
| Full Idea: Liberty is like those solid foods or full-bodied wines appropriate for strengthening robust constitutions that are used to them, but which overpower, ruin and intoxicate the weak and delicate who are not suited to them. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Intro letter) | |
| A reaction: Rousseau vision of a successful society involves robustly self-sufficient citizens (as in the American ideal), rather than people who are free, but easily led into dependence (in a 'nanny state'). |
| 19786 | Three stages of the state produce inequalities of wealth, power, and enslavement [Rousseau] |
| Full Idea: Stage one gives law and property (producing inequalities of rich and poor), stage two gives a magistracy (producing weak and strong), and stage three is legitimate power becoming arbitrary (producing master and slave). | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II) | |
| A reaction: This is the final answer to the prize essay question (with Idea 19772). What a beautiful analysis - and he didn't even win the prize this time! |
| 19788 | The pleasure of wealth and power is largely seeing others deprived of them [Rousseau] |
| Full Idea: If one sees a handful of powerful and rich men at the height of greatness and fortune while the mob grovels in obscurity and misery, it is because the former prize the things they enjoy only to the extent that the others are deprived of them. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II) | |
| A reaction: This seems to be an accurate picture of ancien régime France, and it still applies to modern plutocrats. The pleasure of a nice house is not that it is very good, but that it is better than other houses. Inequality gives a lot of pleasure! |
| 19777 | Persuading other people that some land was 'owned' was the beginning of society [Rousseau] |
| Full Idea: The first person who, having enclosed a plot of land, took it into his head to say 'this is mine' and found people simple enough to believe him, was the true founder of civil society. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II) | |
| A reaction: A wonderful riposte to Locke, who thought political legitimacy was based on property! Locke is way too simplistic about whether someone has a true right to their property. Highy dubious claims become ossified after a generation or two. |
| 19782 | What else could property arise from, but the labour people add to it? [Rousseau] |
| Full Idea: It is impossible to conceive of the idea of property arising from anything but manual labour, for it is not clear what man can add, beyond his own labour, in order to appropriate things he has not made. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II) | |
| A reaction: A thorough endorsement of Locke's labour theory of value. It is not clear to me why you have to 'add' something in order to achieve ownership. Don't you own firewood just by picking it up? Golfers give ownership of a lost ball to the first one to see it. |
| 19781 | Land cultivation led to a general right of ownership, administered justly [Rousseau] |
| Full Idea: From the cultivation of land, there necessarily followed the division of land; and from property once recognised, the first rules of justice. For in order to render everyone what is his, it is necessary that everyone can have something. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II) | |
| A reaction: This looks rather obviously correct. You don't plant crops if you are not protected in your right to reap what you have sown, and you would expect to re-sow from the proceeds. Other people will want you to do this. |
| 19754 | If we have a natural right to property, what exactly does 'belonging to' mean? [Rousseau] |
| Full Idea: Others have spoken of the natural right that everyone has to preserve what belongs to him, without explaining what they mean by 'belonging'. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Pref) | |
| A reaction: This is aimed at Locke. What Marxists will challenge is the legitimacy of property ownership, granted by patronage, enclosure, exploitation and conquest. These start as injustices, but that fades after a few generations. Locke has a labour-theory. |
| 19750 | Writers just propose natural law as the likely useful agreements among people [Rousseau] |
| Full Idea: Writers begin by seeking the rules on which, for the common utility, it would be appropriate for men to agree among themselves; they then give the name of 'natural law' to these rules, with no other proof than their presumed good results. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Pref) | |
| A reaction: The arguments for natural law strike me as quite good, but pinning down its content looks incredibly elusive, and at the mercy of cultural influences. |
| 19770 | Primitive people simply redressed the evil caused by violence, without thought of punishing [Rousseau] |
| Full Idea: More primitive men regarded the acts of violence that could befall them as an easily redressed evil and not as an offence that must be punished; they did not even dream of vengeance, except as a knee-jerk response. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: This may be Rousseau at his most optimistic, trying to deny a rather more aggressive streak in people, seen in children's playgrounds. |
| 19783 | A state of war remains after a conquest, if the losers don't accept the winners [Rousseau] |
| Full Idea: The conqueror and conquered peoples always remain in a state of war with one another, unless the nation, returned to full liberty, were to choose voluntarily its conqueror as leader. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II) | |
| A reaction: Tricky if part of the conquered nation accepts the conqueror, and the other part doesn't, as in France in 1940. In a permanent conquest the state of war seems to fade away, as in England in 1066. |
| 19753 | Both men and animals are sentient, which should give the latter the right not to be mistreated [Rousseau] |
| Full Idea: Since being sentient is common to both animals and men, that should at least give the former the right not to be needlessly mistreated by the latter. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Pref) | |
| A reaction: This is why utilitarianism led to the founding of the RSPCA in Britain. There is a disturbing picture of people smashing up animals for fun, if they can only persuade themselves that the animals are not sentient. I've heard fishermen claim that. |
| 12125 | Teleological accounts are fine in metaphysics, but they stop us from searching for the causes [Bacon] |
| Full Idea: To say 'leaves are for protecting of fruit', or that 'clouds are for watering the earth', is well inquired and collected in metaphysic, but in physic they are impertinent. They are hindrances, and the search of the physical causes hath been neglected. | |
| From: Francis Bacon (The Advancement of Learning [1605], II.VII.7) | |
| A reaction: This is the standard rebellion against Aristotle which gave rise to the birth of modern science. The story has been complicated by natural selection, which bestows a sort of purpose on living things. Nowadays we pursue both paths. |
| 19761 | Men started with too few particular names, but later had too few natural kind names [Rousseau] |
| Full Idea: Men at first unduly multiplied the names of individual things, owing to their failure to know the genera and species, but later made too few genera and species, owing to their failure to have considered beings in all their differences. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: The fact that two leopards differ is not a good enough reason to assign them to two different general terms. Adjectives can do all the necessary modification. The single general term acknowledges something important. |
| 12118 | Essences are part of first philosophy, but as part of nature, not part of logic [Bacon] |
| Full Idea: I assign to summary philosophy the operation of essences (as quantity, similitude, diversity, possibility), with this distinction - that they be handled as they have efficacy in nature, and not logically. | |
| From: Francis Bacon (The Advancement of Learning [1605], II.VII.3) | |
| A reaction: I take this to be a splendid motto for scientific essentialism, in a climate where modal logicians appear to have taken over the driving seat in our understanding of essences. |
| 16922 | Space must have three dimensions, because only three lines can meet at right angles [Kant] |
| Full Idea: That complete space …has three dimensions, and that space in general cannot have more, is built on the proposition that not more than three lines can intersect at right angles in a point. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 285) | |
| A reaction: Modern geometry seems to move, via the algebra, to more than three dimensions, and then battles for an intuition of how that can be. I don't know how they would respond to Kant's challenge here. |
| 16921 | If all empirical sensation of bodies is removed, space and time are still left [Kant] |
| Full Idea: If everything empirical, namely what belongs to sensation, is taken away from the empirical intuition of bodies and their changes (motion), space and time are still left. | |
| From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 284) | |
| A reaction: This is an exercise in psychological abstraction, which doesn't sound like good evidence, though it is an interesting claim. Physicists want to hijack this debate, but I like Kant's idea. |
| 19776 | Small uninterrupted causes can have big effects [Rousseau] |
| Full Idea: Negligible causes may have surprising power when they act without interruption. | |
| From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I) | |
| A reaction: A wonderfully simple observation that is a key idea of the theory of evolution. If life was created 6,000 years ago, evolution is impossible. If it appeared 500,000,000 years ago, how could evolution NOT occur? Little changes must occur. |
