93 ideas
| 19693 | There is practical wisdom (for action), and theoretical wisdom (for deep understanding) [Aristotle, by Whitcomb] |
| Full Idea: Aristotle takes wisdom to come in two forms, the practical and the theoretical, the former of which is good judgement about how to act, and the latter of which is deep knowledge or understanding. | |
| From: report of Aristotle (works [c.330 BCE]) by Dennis Whitcomb - Wisdom Intro | |
| A reaction: The interesting question is then whether the two are connected. One might be thoroughly 'sensible' about action, without counting as 'wise', which seems to require a broader view of what is being done. Whitcomb endorses Aristotle on this idea. |
| 18330 | Judging by the positive forces, the Renaissance was the last great age [Nietzsche] |
| Full Idea: Ages are to be assessed by their positive forces - and by this assessment the age of the Renaissance, so prodigal and so fateful, appears as the last great age. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.37) | |
| A reaction: I suspect that Nietzsche places art very high among the positive forces. Science and technology showed barely a glimmer during the Renaissance. Mathematics moved very little, Copernicus was ignored, and logic was static. |
| 2900 | I revere Heraclitus [Nietzsche] |
| Full Idea: I set apart with high reverence the name of Heraclitus. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.2) |
| 2913 | Thucydides was the perfect anti-platonist sophist [Nietzsche] |
| Full Idea: My recreation, my preference, my cure from all Platonism has always been Thucydides. …Sophist culture, by which I mean realist culture, attains in him its perfect expression. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 9.2) |
| 2909 | Thinking has to be learned in the way dancing has to be learned [Nietzsche] |
| Full Idea: Thinking has to be learned in the way dancing has to be learned. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 7.7) | |
| A reaction: Nice. At its deepest level thinking isn't a rational process? |
| 2892 | Wanting a system in philosophy is a lack of integrity [Nietzsche] |
| Full Idea: I mistrust all systematizers and avoid them. The will to system is a lack of integrity. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], Maxim 26) |
| 1575 | For Aristotle logos is essentially the ability to talk rationally about questions of value [Roochnik on Aristotle] |
| Full Idea: For Aristotle logos is the ability to speak rationally about, with the hope of attaining knowledge, questions of value. | |
| From: comment on Aristotle (works [c.330 BCE]) by David Roochnik - The Tragedy of Reason p.26 |
| 1589 | Aristotle is the supreme optimist about the ability of logos to explain nature [Roochnik on Aristotle] |
| Full Idea: Aristotle is the great theoretician who articulates a vision of a world in which natural and stable structures can be rationally discovered. His is the most optimistic and richest view of the possibilities of logos | |
| From: comment on Aristotle (works [c.330 BCE]) by David Roochnik - The Tragedy of Reason p.95 |
| 2896 | I want to understand the Socratic idea that 'reason equals virtue equals happiness' [Nietzsche] |
| Full Idea: I seek to understand out of what idiosyncrasy that Socratic equation 'reason equals virtue equals happiness' derives. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.04) |
| 4642 | No fact can be real and no proposition true unless there is a Sufficient Reason (even if we can't know it) [Leibniz] |
| Full Idea: The principle of sufficient reason says no fact can be real or existing and no proposition can be true unless there is a sufficient reason why it should be thus and not otherwise, even though in most cases these reasons cannot be known to us. | |
| From: Gottfried Leibniz (Monadology [1716], §32) | |
| A reaction: I think of this as my earliest philosophical perception, a childish rebellion against being told that there was 'no reason' for something. My intuition tells me that it is correct, and the foundation of ontology and truth. Don't ask me to justify it! |
| 2897 | With dialectics the rabble gets on top [Nietzsche] |
| Full Idea: With dialectics the rabble gets on top. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.05) |
| 8200 | Aristotelian definitions aim to give the essential properties of the thing defined [Aristotle, by Quine] |
| Full Idea: A real definition, according to the Aristotelian tradition, gives the essence of the kind of thing defined. Man is defined as a rational animal, and thus rationality and animality are of the essence of each of us. | |
| From: report of Aristotle (works [c.330 BCE]) by Willard Quine - Vagaries of Definition p.51 | |
| A reaction: Compare Idea 4385. Personally I prefer the Aristotelian approach, but we may have to say 'We cannot identify the essence of x, and so x cannot be defined'. Compare 'his mood was hard to define' with 'his mood was hostile'. |
| 4385 | Aristotelian definition involves first stating the genus, then the differentia of the thing [Aristotle, by Urmson] |
| Full Idea: For Aristotle, to give a definition one must first state the genus and then the differentia of the kind of thing to be defined. | |
| From: report of Aristotle (works [c.330 BCE]) by J.O. Urmson - Aristotle's Doctrine of the Mean p.157 | |
| A reaction: Presumably a modern definition would just be a list of properties, but Aristotle seeks the substance. How does he define a genus? - by placing it in a further genus? |
| 2898 | Anything which must first be proved is of little value [Nietzsche] |
| Full Idea: What has first to have itself proved is of little value. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.05) |
| 2115 | Everything in the universe is interconnected, so potentially a mind could know everything [Leibniz] |
| Full Idea: Every body is sensitive to everything in the universe, so that one who saw everything could read in each body what is happening everywhere, and even what has happened and will happen. | |
| From: Gottfried Leibniz (Monadology [1716], §61) |
| 13282 | Aristotle relativises the notion of wholeness to different measures [Aristotle, by Koslicki] |
| Full Idea: Aristotle proposes to relativise unity and plurality, so that a single object can be both one (indivisible) and many (divisible) simultaneously, without contradiction, relative to different measures. Wholeness has degrees, with the strength of the unity. | |
| From: report of Aristotle (works [c.330 BCE]) by Kathrin Koslicki - The Structure of Objects 7.2.12 | |
| A reaction: [see Koslicki's account of Aristotle for details] As always, the Aristotelian approach looks by far the most promising. Simplistic mechanical accounts of how parts make wholes aren't going to work. We must include the conventional and conceptual bit. |
| 2111 | Falsehood involves a contradiction, and truth is contradictory of falsehood [Leibniz] |
| Full Idea: We judge to be false that which involves a contradiction, and true that which is opposed or contradictory to the false. | |
| From: Gottfried Leibniz (Monadology [1716], §31) |
| 4730 | For Aristotle, the subject-predicate structure of Greek reflected a substance-accident structure of reality [Aristotle, by O'Grady] |
| Full Idea: Aristotle apparently believed that the subject-predicate structure of Greek reflected the substance-accident nature of reality. | |
| From: report of Aristotle (works [c.330 BCE]) by Paul O'Grady - Relativism Ch.4 | |
| A reaction: We need not assume that Aristotle is wrong. It is a chicken-and-egg. There is something obvious about subject-predicate language, if one assumes that unified objects are part of nature, and not just conventional. |
| 18317 | The 'real being' of things is a nothingness constructed from contradictions in the actual world [Nietzsche] |
| Full Idea: The characteristics which have been assigned to the 'real being' of things are the characteristics of non-being, of nothingness - the 'real world has been constructed out of the contradiction of the actual world. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.6) | |
| A reaction: I take this to be a critique of Hegel, in particular. Could we describe the metaphysics of Nietzsche as 'constructivist'? I certainly think he is underrated as a metaphysician, because the ideas are so fragmentary. |
| 18315 | We get the concept of 'being' from the concept of the 'ego' [Nietzsche] |
| Full Idea: Being is everywhere thought in, foisted on, as cause; it is only from the conception 'ego' that there follows, derivatively, the concept 'being'. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.5) | |
| A reaction: 'Being' is such a remote abstraction that I doubt whether we can say anything at all meaningful about where it 'comes from'. |
| 7644 | The monad idea incomprehensibly spiritualises matter, instead of materialising soul [La Mettrie on Leibniz] |
| Full Idea: The Leibnizians with their monads have constructed an incomprehensible hypothesis. They have spiritualized matter rather than materialising the soul. | |
| From: comment on Gottfried Leibniz (Monadology [1716]) by Julien Offray de La Mettrie - Machine Man p.3 | |
| A reaction: I agree with La Mettrie. This disagreement shows, I think, how important the problem of interaction between mind and body was in the century after Descartes. Drastic action seemed needed to bridge the gap, one way or the other. |
| 11857 | He replaced Aristotelian continuants with monads [Leibniz, by Wiggins] |
| Full Idea: In the end Leibniz dethroned Aristotelian continuants, seen as imperfect from his point of view, in favour of monads. | |
| From: report of Gottfried Leibniz (Monadology [1716]) by David Wiggins - Sameness and Substance Renewed 3.1 | |
| A reaction: I take the 'continuants' to be either the 'ultimate subject of predication' (in 'Categories'), or 'essences' (in 'Metaphysics'). Since monads seem to be mental (presumably to explain the powers of things), this strikes me as a bit mad. |
| 7843 | Is a drop of urine really an infinity of thinking monads? [Voltaire on Leibniz] |
| Full Idea: Can you really maintain that a drop of urine is an infinity of monads, and that each one of these has ideas, however obscure, of the entire universe? | |
| From: comment on Gottfried Leibniz (Monadology [1716]) by Francois-Marie Voltaire - works Vol 22:434 | |
| A reaction: Monads are a bit like Christian theology - if you meet them cold they seem totally ridiculous, but if you meet them after ten years of careful preliminary study they make (apparently) complete sense. Defenders of panpsychism presumably like them. |
| 12751 | It is unclear in 'Monadology' how extended bodies relate to mind-like monads. [Garber on Leibniz] |
| Full Idea: It is never clear in the 'Monadologie' how exactly the world of extended bodies is related to the world of simple substances, the world of non-extended and mind-like monads. | |
| From: comment on Gottfried Leibniz (Monadology [1716]) by Daniel Garber - Leibniz:Body,Substance,Monad 9 | |
| A reaction: Leibniz was always going to hit the interaction problem, as soon as he started giving an increasingly spiritual account of what a substance, and hence marginalising the 'force' which had held centre-stage earlier on. Presumably they are 'parallel'. |
| 19363 | Changes in a monad come from an internal principle, and the diversity within its substance [Leibniz] |
| Full Idea: A monad's natural changes come from an internal principle, ...but there must be diversity in that which changes, which produces the specification and variety of substances. | |
| From: Gottfried Leibniz (Monadology [1716], §11-12) | |
| A reaction: You don't have to like monads to like this generalisation (and Perkins says Leibniz had a genius for generalisations). Metaphysics must give an account of change. Succeeding time-slices etc explain nothing. Principle and substance must meet. |
| 19352 | A 'monad' has basic perception and appetite; a 'soul' has distinct perception and memory [Leibniz] |
| Full Idea: The general name 'monad' or 'entelechy' may suffice for those substances which have nothing but perception and appetition; the name 'souls' may be reserved for those having perception that is more distinct and accompanied by memory. | |
| From: Gottfried Leibniz (Monadology [1716], §19) | |
| A reaction: It is basic to the study of Leibniz that you don't think monads are full-blown consciousnesses. He isn't really a panpsychist, because the level of mental activity is so minimal. There seem to be degrees of monadhood. |
| 18316 | The grounds for an assertion that the world is only apparent actually establish its reality [Nietzsche] |
| Full Idea: The grounds upon which 'this' world has been designated as apparent establish rather its reality - another kind of reality is absolutely undemonstrable. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.6) |
| 18314 | In language we treat 'ego' as a substance, and it is thus that we create the concept 'thing' [Nietzsche] |
| Full Idea: It is the metaphysics of language (that is, of reason) ....which believes in the 'ego', in the ego as being, in the ego as substance, and which projects its belief in the ego-substance on to all things - only thus does it create the concept 'thing'. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.5) |
| 7931 | If a substance is just a thing that has properties, it seems to be a characterless non-entity [Leibniz, by Macdonald,C] |
| Full Idea: For Leibniz, to distinguish between a substance and its properties in order to provide a thing or entity in which properties can inhere leads necessarily to the absurd conclusion that the substance itself must be a truly characterless non-entity. | |
| From: report of Gottfried Leibniz (Monadology [1716]) by Cynthia Macdonald - Varieties of Things Ch.3 | |
| A reaction: This is obviously one of the basic thoughts in any discussion of substances. It is why physicists ignore them, and Leibniz opted for a 'bundle' theory. But the alternative seems daft too - free-floating properties, hooked onto one another. |
| 13276 | The unmoved mover and the soul show Aristotelian form as the ultimate mereological atom [Aristotle, by Koslicki] |
| Full Idea: Aristotle's discussion of the unmoved mover and of the soul confirms the suspicion that form, when it is not thought of as the object represented in a definition, plays the role of the ultimate mereological atom within his system. | |
| From: report of Aristotle (works [c.330 BCE]) by Kathrin Koslicki - The Structure of Objects 6.6 | |
| A reaction: Aristotle is concerned with which things are 'divisible', and he cites these two examples as indivisible, but they may be too unusual to offer an actual theory of how Aristotle builds up wholes from atoms. He denies atoms in matter. |
| 13277 | The 'form' is the recipe for building wholes of a particular kind [Aristotle, by Koslicki] |
| Full Idea: Thus in Aristotle we may think of an object's formal components as a sort of recipe for how to build wholes of that particular kind. | |
| From: report of Aristotle (works [c.330 BCE]) by Kathrin Koslicki - The Structure of Objects 7.2.5 | |
| A reaction: In the elusive business of pinning down what Aristotle means by the crucial idea of 'form', this analogy strikes me as being quite illuminating. It would fit DNA in living things, and the design of an artifact. |
| 17554 | There must be some internal difference between any two beings in nature [Leibniz] |
| Full Idea: There are never two beings in nature that are perfectly alike, two beings in which it is not possible to discover an internal difference, that is, one founded on an intrinsic denomination. | |
| From: Gottfried Leibniz (Monadology [1716], §09) | |
| A reaction: From this it follows that if two things really are indiscernible, then we must say that they are one thing. He says monads all differ from one another. People certainly do. Leibniz must say this of electrons. How can he know this? |
| 2112 | Truths of reason are known by analysis, and are necessary; facts are contingent, and their opposites possible [Leibniz] |
| Full Idea: There are two kinds of truths: of reasoning and of facts. Truths of reasoning are necessary and their opposites impossible. Facts are contingent and their opposites possible. A necessary truth is known by analysis. | |
| From: Gottfried Leibniz (Monadology [1716], §33) |
| 5991 | For Aristotle, knowledge is of causes, and is theoretical, practical or productive [Aristotle, by Code] |
| Full Idea: Aristotle thinks that in general we have knowledge or understanding when we grasp causes, and he distinguishes three fundamental types of knowledge - theoretical, practical and productive. | |
| From: report of Aristotle (works [c.330 BCE]) by Alan D. Code - Aristotle | |
| A reaction: Productive knowledge we tend to label as 'knowing how'. The centrality of causes for knowledge would get Aristotle nowadays labelled as a 'naturalist'. It is hard to disagree with his three types, though they may overlap. |
| 11239 | The notion of a priori truth is absent in Aristotle [Aristotle, by Politis] |
| Full Idea: The notion of a priori truth is conspicuously absent in Aristotle. | |
| From: report of Aristotle (works [c.330 BCE]) by Vassilis Politis - Aristotle and the Metaphysics 1.5 | |
| A reaction: Cf. Idea 11240. |
| 9344 | Mathematical analysis ends in primitive principles, which cannot be and need not be demonstrated [Leibniz] |
| Full Idea: At the end of the analytical method in mathematics there are simple ideas of which no definition can be given. Moreover there are axioms and postulates, in short, primitive principles, which cannot be demonstrated and do not need demonstration. | |
| From: Gottfried Leibniz (Monadology [1716], §35) | |
| A reaction: My view is that we do not know such principles when we apprehend them in isolation. I would call them 'intuitions'. They only ascend to the status of knowledge when the mathematics is extended and derived from them, and found to work. |
| 18309 | The evidence of the senses is falsified by reason [Nietzsche] |
| Full Idea: 'Reason' is the cause of our falsification of the evidence of the senses. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.1) | |
| A reaction: One for McDowell. |
| 23312 | Aristotle is a rationalist, but reason is slowly acquired through perception and experience [Aristotle, by Frede,M] |
| Full Idea: Aristotle is a rationalist …but reason for him is a disposition which we only acquire over time. Its acquisition is made possible primarily by perception and experience. | |
| From: report of Aristotle (works [c.330 BCE]) by Michael Frede - Aristotle's Rationalism p.173 | |
| A reaction: I would describe this process as the gradual acquisition of the skill of objectivity, which needs the right knowledge and concepts to evaluate new experiences. |
| 2110 | We all expect the sun to rise tomorrow by experience, but astronomers expect it by reason [Leibniz] |
| Full Idea: When we expect it to be day tomorrow, we all behave as empiricists, because until now it has always happened thus. The astronomer alone knows this by reason. | |
| From: Gottfried Leibniz (Monadology [1716], §28) |
| 16111 | Aristotle wants to fit common intuitions, and therefore uses language as a guide [Aristotle, by Gill,ML] |
| Full Idea: Since Aristotle generally prefers a metaphysical theory that accords with common intuitions, he frequently relies on facts about language to guide his metaphysical claims. | |
| From: report of Aristotle (works [c.330 BCE]) by Mary Louise Gill - Aristotle on Substance Ch.5 | |
| A reaction: I approve of his procedure. I take intuition to be largely rational justifications too complex for us to enunciate fully, and language embodies folk intuitions in its concepts (especially if the concepts occur in many languages). |
| 16971 | Plato says sciences are unified around Forms; Aristotle says they're unified around substance [Aristotle, by Moravcsik] |
| Full Idea: Plato's unity of science principle states that all - legitimate - sciences are ultimately about the Forms. Aristotle's principle states that all sciences must be, ultimately, about substances, or aspects of substances. | |
| From: report of Aristotle (works [c.330 BCE], 1) by Julius Moravcsik - Aristotle on Adequate Explanations 1 |
| 11243 | Aristotelian explanations are facts, while modern explanations depend on human conceptions [Aristotle, by Politis] |
| Full Idea: For Aristotle things which explain (the explanantia) are facts, which should not be associated with the modern view that says explanations are dependent on how we conceive and describe the world (where causes are independent of us). | |
| From: report of Aristotle (works [c.330 BCE]) by Vassilis Politis - Aristotle and the Metaphysics 2.1 | |
| A reaction: There must be some room in modern thought for the Aristotelian view, if some sort of robust scientific realism is being maintained against the highly linguistic view of philosophy found in the twentieth century. |
| 3320 | Aristotle's standard analysis of species and genus involves specifying things in terms of something more general [Aristotle, by Benardete,JA] |
| Full Idea: The standard Aristotelian doctrine of species and genus in the theory of anything whatever involves specifying what the thing is in terms of something more general. | |
| From: report of Aristotle (works [c.330 BCE]) by José A. Benardete - Metaphysics: the logical approach Ch.10 |
| 12000 | Aristotle regularly says that essential properties explain other significant properties [Aristotle, by Kung] |
| Full Idea: The view that essential properties are those in virtue of which other significant properties of the subjects under investigation can be explained is encountered repeatedly in Aristotle's work. | |
| From: report of Aristotle (works [c.330 BCE]) by Joan Kung - Aristotle on Essence and Explanation IV | |
| A reaction: What does 'significant' mean here? I take it that the significant properties are the ones which explain the role, function and powers of the object. |
| 18323 | Any explanation will be accepted as true if it gives pleasure and a feeling of power [Nietzsche] |
| Full Idea: To trace something unknown back to something known is alleviating, soothing, gratifying and gives moreover a feeling of power. ...First principle: any explanation is better than none. ...Proof by pleasure ('by potency') as criterion of truth. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 5.5) | |
| A reaction: By 'proof by pleasure' he means that we find an explanation so satisfying that we cling to it. I assume it is a criterion of rationality (an epistemic virtue) to reject the principle 'any explanation is better than none'. Negative capability. |
| 2109 | Increase a conscious machine to the size of a mill - you still won't see perceptions in it [Leibniz] |
| Full Idea: If a conscious machine were increased in size, one might enter it like a mill, but we should only see the parts impinging on one another; we should not see anything which would explain a perception. | |
| From: Gottfried Leibniz (Monadology [1716], §17) | |
| A reaction: A wonderful image for capturing a widely held intuition. It seems to motivate Colin McGinn's 'Mysterianism'. The trouble is Leibniz didn't think big/small enough. Down at the level of molecules it might become obvious what a perception is. 'Might'. |
| 18310 | The 'highest' concepts are the most general and empty concepts [Nietzsche] |
| Full Idea: The 'highest concepts' ...are the most general, the emptiest concepts, the last fumes of evaporating reality. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.4) | |
| A reaction: This could be seen as an attack on the aspirations of all of philosophy, which seeks general truths out of the chaos of experience. Should we shut up, then, and just be and do? |
| 19362 | We know the 'I' and its contents by abstraction from awareness of necessary truths [Leibniz] |
| Full Idea: It is through the knowledge of necessary truths and through their abstraction that we rise to reflective acts, which enable us to think of that which is called "I" and enable us to consider that this or that is in us. | |
| From: Gottfried Leibniz (Monadology [1716], §30) | |
| A reaction: For Leibniz, necessary truth can only be known a priori. Sense experience won't reveal the self, as Hume observed. We evidently 'abstract' the idea of 'I' from the nature of a priori thought. Animals have no self (or morals) for this reason. |
| 20368 | There are no 'individual' persons; we are each the sum of humanity up to this moment [Nietzsche] |
| Full Idea: The 'individual' ...is an error: he does not constitute a separate entity, an atom, a 'link in the chain', something merely inherited from the past - he constitutes the entire single line 'man' up to and including himself. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.33) | |
| A reaction: I'm not sure I understand this, but you can sort of imagine yourself as a culmination of something, rather than as an isolated entity. I'm not sure how that is supposed to affect my behaviour. |
| 2899 | The fanatical rationality of Greek philosophy shows that they were in a state of emergency [Nietzsche] |
| Full Idea: The fanaticism with which the whole of Greek thought throws itself at rationality betrays itself as a state of emergency: one was in peril, one had only one choice: either to perish or- be absurdly rational. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.10) |
| 23300 | Aristotle and the Stoics denied rationality to animals, while Platonists affirmed it [Aristotle, by Sorabji] |
| Full Idea: Aristotle, and also the Stoics, denied rationality to animals. …The Platonists, the Pythagoreans, and some more independent Aristotelians, did grant reason and intellect to animals. | |
| From: report of Aristotle (works [c.330 BCE]) by Richard Sorabji - Rationality 'Denial' | |
| A reaction: This is not the same as affirming or denying their consciousness. The debate depends on how rationality is conceived. |
| 11240 | The notion of analytic truth is absent in Aristotle [Aristotle, by Politis] |
| Full Idea: The notion of analytic truth is conspicuously absent in Aristotle. | |
| From: report of Aristotle (works [c.330 BCE]) by Vassilis Politis - Aristotle and the Metaphysics 1.5 | |
| A reaction: Cf. Idea 11239. |
| 18313 | The big error is to think the will is a faculty producing effects; in fact, it is just a word [Nietzsche] |
| Full Idea: At the beginning stands the great fateful error that the will is something which produces an effect - that will is a faculty.... Today we know it is merely a word. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.5) | |
| A reaction: This is despite Nietzsche's insistence that 'will to power' is the central fact of active existence. The misreading of Nietzsche is to think that this refers to the conscious exercising of a mental faculty. |
| 20133 | The 'motive' is superficial, and may even hide the antecedents of a deed [Nietzsche] |
| Full Idea: The so-called 'motive' is another error. Merely a surface phenomenon of consciousness - something alongside the deed which is more likely to cover up the antecedents of the deed than to represent them. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 6.3) | |
| A reaction: [Leiter gives 'VI.3', but I can't find it] As far as you can get from intellectualism about action, and is more in accord with the picture found in modern neuro-science. No one knows why they are 'interested' in something, and that's the start of it. |
| 18326 | The beautiful never stands alone; it derives from man's pleasure in man [Nietzsche] |
| Full Idea: Anyone who tried to divorce the beautiful from man's pleasure in man would at once feel the ground give way beneath him. The 'beautiful in itself' is not even a concept, merely a phrase. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.19) | |
| A reaction: I love the insult 'not even a concept'! It's like Pauli's 'not even wrong'! |
| 20101 | Without music life would be a mistake [Nietzsche] |
| Full Idea: Without music life would be a mistake. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], Maxim 33) | |
| A reaction: Cf Schopenhauer in Idea 21469. If you, dear reader, don't love music, then I sincerely hope that there is something in your life which can match it. |
| 2902 | Healthy morality is dominated by an instinct for life [Nietzsche] |
| Full Idea: All naturalism in morality, that is all healthy morality, is dominated by an instinct for life. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.4) | |
| A reaction: Sounds right. There is no reasoning against a moral nihilist, because they seem to have no instinct in favour of life. It is the given of morality. |
| 18311 | Philosophers hate values having an origin, and want values to be self-sufficient [Nietzsche] |
| Full Idea: For philosophers, the higher must not be allowed to grow out of the lower, must not be allowed to have grown at all ...Moral: everything of the first rank must be causa sui. Origin in something else counts as an objection, as casting a doubt on value. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.4) | |
| A reaction: This is so deep and central that I wrote a paper on it, advocating that the theory of values should focus of value-makers. |
| 18324 | There are no moral facts, and moralists believe in realities which do not exist [Nietzsche] |
| Full Idea: An insight formulated by me: that there are no moral facts whatever. Moral judgement has this in common with religious judgement that it believes in realities which do not exist. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 6.1) | |
| A reaction: Not only a slogan for non-cognitivism, but also a clear statement of the error theory about morality, a century before John Mackie. |
| 2904 | The doctrine of free will has been invented essentially in order to blame and punish people [Nietzsche] |
| Full Idea: The doctrine of will has been invented essentially for the purpose of punishment, that is of finding guilty. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 5.7) | |
| A reaction: Michael Frede says free will was invented to feel wholly in charge of our own actions. I doubt whether punishment was the first motive. The will just gives a simple explanation of actions. |
| 6559 | Aristotle never actually says that man is a rational animal [Aristotle, by Fogelin] |
| Full Idea: To the best of my knowledge (and somewhat to my surprise), Aristotle never actually says that man is a rational animal; however, he all but says it. | |
| From: report of Aristotle (works [c.330 BCE]) by Robert Fogelin - Walking the Tightrope of Reason Ch.1 | |
| A reaction: When I read this I thought that this database would prove Fogelin wrong, but it actually supports him, as I can't find it in Aristotle either. Descartes refers to it in Med.Two. In Idea 5133 Aristotle does say that man is a 'social being'. But 22586! |
| 2894 | Value judgements about life can never be true [Nietzsche] |
| Full Idea: Judgements, value judgements concerning life, for or against it, can in the last resort never be true. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.02) | |
| A reaction: I suppose this is in the same spirit as judging whether celery tastes nice. Are you for or against the Moon? |
| 18321 | To evaluate life one must know it, but also be situated outside of it [Nietzsche] |
| Full Idea: One would have to be situated outside life ....[and yet know it thoroughly] ....to be permitted to touch on the problem of the value of life at all. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.5) | |
| A reaction: Can practising artists question the value of their art? The whole point of objectivity is that we can mentally step 'outside' of something, without actually withdrawing from it. |
| 2895 | The value of life cannot be estimated [Nietzsche] |
| Full Idea: The value of life cannot be estimated. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.02) | |
| A reaction: Military leaders apparently judge that the death of one of their own soldiers is worth between 12 and 20 enemy deaths (so history suggests). How about ransom money? |
| 18322 | When we establish values, that is life itself establishing them, through us [Nietzsche] |
| Full Idea: When we speak of values we do so under the inspiration and from the perspective of life: life itself evaluates through us when we establish values | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.5) | |
| A reaction: I love Nietzsche's ideas about the source of values, and his remarks about the value of life. Other thinkers sound so simplistic in comparison. |
| 2893 | In every age the wisest people have judged life to be worthless [Nietzsche] |
| Full Idea: In every age the wisest have passed the identical judgement on life: it is worthless. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.01) | |
| A reaction: I guess he was having a bad day. Since the whole universe is clearly 'worthless', this judgement must in some sense be correct. But I love my books. |
| 18308 | A philosopher fails in wisdom if he thinks the value of life is a problem [Nietzsche] |
| Full Idea: For a philosopher to see a problem in the value of life thus even constitutes an objection to him, a question-mark as to his wisdom, a piece of unwisdom. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.02) | |
| A reaction: I take his point to be neither that life is unquestionably valuable nor that it is valueless, but that the very question is ridiculous. If we live, we value living. Sounds right. |
| 18319 | Love is the spiritualisation of sensuality [Nietzsche] |
| Full Idea: The spiritualization of sensuality is called 'love': it is a great triumph over Christianity. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.3) | |
| A reaction: I'm not quite clear what 'spiritualization' means, particularly when it comes from Nietzsche. |
| 2903 | A good human will be virtuous because they are happy [Nietzsche] |
| Full Idea: A well-constituted human being, a 'happy one', must perform certain actions and shrink from other actions. In a formula: his virtue is the consequence of his happiness. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 5.2) | |
| A reaction: A nice reversal of basic Aristotle, though Aristotle does say that the truly virtuous person is happy in their actions. Treat unhappy people with caution! |
| 2891 | Only the English actually strive after happiness [Nietzsche] |
| Full Idea: Man does not strive after happiness; only the Englishman does that. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], Maxim 12) | |
| A reaction: The Danes keeping being voted the happiest nation, so presumably that results from some sort of effort on their part. The easiest is happiness is to achieve security, then do nothing. |
| 18327 | A wholly altruistic morality, with no egoism, is a thoroughly bad thing [Nietzsche] |
| Full Idea: An 'altruistic' morality, a morality under which egoism languishes - is under all circumstances a bad sign. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.35) |
| 15606 | Military idea: what does not kill me makes me stronger [Nietzsche] |
| Full Idea: From the military school of life. - What does not kill me makes me stronger. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], Maxim 08) | |
| A reaction: The published version! Perhaps the most famous remark in all of Nietzsche, and no one realises it is ironic! It is a sarcastic remark about the battering ram mentality of the Prussian militarist! He had served in the army. |
| 18328 | Invalids are parasites [Nietzsche] |
| Full Idea: The invalid is a parasite on society. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.36) | |
| A reaction: I'll skip the rest, but you get the idea. The point (with which I sympathise) is that life is primarily about what healthy people do. Something has gone wrong if all we do is worry about the sick and the suffering. |
| 18331 | Democracy is organisational power in decline [Nietzsche] |
| Full Idea: Democracy has always been the declining form of the power to organise. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.39) | |
| A reaction: Even when Nietzsche is wrong (and who knows, here?) he always challenges you to think! |
| 18332 | The creation of institutions needs a determination which is necessarily anti-liberal [Nietzsche] |
| Full Idea: For institutions to exist there must exist the kind of will, instinct, imperative which is anti-liberal to the point of malice: the will to tradition, to authority, to centuries-long responsibility, to solidarity between succeeding generations. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.39) | |
| A reaction: This sounds like a lovely challenge to Popper, who seems to have been a liberal who pinned his faith on institutions. |
| 2911 | True justice is equality for equals and inequality for unequals [Nietzsche] |
| Full Idea: 'Equality for equals, inequality for unequals' - that would be the true voice of justice. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.48) |
| 18320 | To renounce war is to renounce the grand life [Nietzsche] |
| Full Idea: One has renounced grand life when one renounces war. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.3) | |
| A reaction: Nietzsche was a medical orderly in the 1870 Franco-Prussian war, so he had seen it at first hand. I think the machine gun and the heavy bomber would have changed his attitude to warfare. He sounds a bit silly now. Nostalgia for the Iliad. |
| 11150 | It is the mark of an educated mind to be able to entertain an idea without accepting it [Aristotle] |
| Full Idea: It is the mark of an educated mind to be able to entertain an idea without accepting it. | |
| From: Aristotle (works [c.330 BCE]) | |
| A reaction: The epigraph on a David Chalmers website. A wonderful remark, and it should be on the wall of every beginners' philosophy class. However, while it is in the spirit of Aristotle, it appears to be a misattribution with no ancient provenance. |
| 3037 | Aristotle said the educated were superior to the uneducated as the living are to the dead [Aristotle, by Diog. Laertius] |
| Full Idea: Aristotle was asked how much educated men were superior to those uneducated; "As much," he said, "as the living are to the dead." | |
| From: report of Aristotle (works [c.330 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 05.1.11 |
| 2908 | There is a need for educators who are themselves educated [Nietzsche] |
| Full Idea: There is a need for educators who are themselves educated. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 7.5) |
| 18329 | Sometimes it is an error to have been born - but we can rectify it [Nietzsche] |
| Full Idea: We have no power to prevent ourselves being born: but we can rectify this error - for sometimes it is an error. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.36) |
| 2905 | 'Purpose' is just a human fiction [Nietzsche] |
| Full Idea: We invented the concept 'purpose': in reality purpose is lacking. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 5.8) |
| 8660 | There are potential infinities (never running out), but actual infinity is incoherent [Aristotle, by Friend] |
| Full Idea: Aristotle developed his own distinction between potential infinity (never running out) and actual infinity (there being a collection of an actual infinite number of things, such as places, times, objects). He decided that actual infinity was incoherent. | |
| From: report of Aristotle (works [c.330 BCE]) by Michèle Friend - Introducing the Philosophy of Mathematics 1.3 | |
| A reaction: Friend argues, plausibly, that this won't do, since potential infinity doesn't make much sense if there is not an actual infinity of things to supply the demand. It seems to just illustrate how boggling and uncongenial infinity was to Aristotle. |
| 12058 | Aristotle's matter can become any other kind of matter [Aristotle, by Wiggins] |
| Full Idea: Aristotle's conception of matter permits any kind of matter to become any other kind of matter. | |
| From: report of Aristotle (works [c.330 BCE]) by David Wiggins - Substance 4.11.2 | |
| A reaction: This is obviously crucial background information when we read Aristotle on matter. Our 92+ elements, and fixed fundamental particles, gives a quite different picture. Aristotle would discuss form and matter quite differently now. |
| 12707 | The true elements are atomic monads [Leibniz] |
| Full Idea: Monads are the true atoms of nature and, in brief, the elements of things. | |
| From: Gottfried Leibniz (Monadology [1716], (opening)), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 2 | |
| A reaction: Thus in one sentence Leibniz gives us a theory of natural elements, and an account of atoms. This kind of speculation got metaphysics a bad name when science unravelled a more accurate picture. The bones must be picked out of Leibniz. |
| 2114 | This is the most perfect possible universe, in its combination of variety with order [Leibniz] |
| Full Idea: From all the possible universes God chooses this one to obtain as much variety as possible, but with the greatest order possible; that is, it is the means of obtaining the greatest perfection possible. | |
| From: Gottfried Leibniz (Monadology [1716], §58) |
| 2113 | God alone (the Necessary Being) has the privilege that He must exist if He is possible [Leibniz] |
| Full Idea: God alone (or the Necessary Being) has the privilege that He must exist if He is possible. | |
| From: Gottfried Leibniz (Monadology [1716], §45) |
| 18312 | The supreme general but empty concepts must be compatible, and hence we get 'God' [Nietzsche] |
| Full Idea: The supreme concepts of philosophers cannot be incommensurate with one another, be incompatible with one another... Thus they acquired their stupendous concept 'God'.... The last, thinnest, emptiest is placed as the first, as cause in itself. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.4) |
| 2906 | By denying God we deny human accountability, and thus we redeem the world [Nietzsche] |
| Full Idea: We deny God; in denying God we deny accountability; only by doing that do we redeem the world. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 5.8) |
| 22729 | The concepts of gods arose from observing the soul, and the cosmos [Aristotle, by Sext.Empiricus] |
| Full Idea: Aristotle said that the conception of gods arose among mankind from two originating causes, namely from events which concern the soul and from celestial phenomena. | |
| From: report of Aristotle (works [c.330 BCE], Frag 10) by Sextus Empiricus - Against the Physicists (two books) I.20 | |
| A reaction: The cosmos suggests order, and possible creation. What do events of the soul suggest? It doesn't seem to be its non-physical nature, because Aristotle is more of a functionalist. Puzzling. (It says later that gods are like the soul). |
| 2901 | How could the Church intelligently fight against passion if it preferred poorness of spirit to intelligence? [Nietzsche] |
| Full Idea: The primitive church fought against the 'intelligent' in favour of the 'poor in spirit': how could one expect from it an intelligent war against passion? | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.1) |
| 18325 | Christians believe that only God can know what is good for man [Nietzsche] |
| Full Idea: Christianity presupposes that man does not know, cannot know what is good for him and what evil: he believes in God, who alone knows. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.05) |
| 18318 | People who disparage actual life avenge themselves by imagining a better one [Nietzsche] |
| Full Idea: If there is a strong instinct for slandering, disparaging and accusing life within us, then we revenge ourselves on life by means of the phantasmagoria of 'another', a 'better' life. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.6) |
