40 ideas
| 14888 | Wisdom prevents us from being ruled by the moment [Nietzsche] |
| Full Idea: The most important thing about wisdom is that it prevents human beings from being ruled by the moment. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 30 [25]) |
| 14863 | Unlike science, true wisdom involves good taste [Nietzsche] |
| Full Idea: Inherent in wisdom [sophia] is discrimination, the possession of good taste: whereas science, lacking such a refined sense of taste, gobbles up anything that is worth knowing. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [086]) | |
| A reaction: This is blatantly unfair to science, which may lack 'taste', but at least prefers deep theories with wide-ranging explanatory power to narrow local theories. Maybe the line across the philosophical community is the one picking out those with taste? |
| 14890 | Suffering is the meaning of existence [Nietzsche] |
| Full Idea: Suffering is the meaning of existence. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 32 [67]) | |
| A reaction: This doesn't mean that he is advocating suffering. The context of his remark is that the pursuit of truth involves suffering. |
| 14861 | Philosophy ennobles the world, by producing an artistic conception of our knowledge [Nietzsche] |
| Full Idea: Philosophy is indispensable for education because it draws knowledge into an artistic conception of the world, and thereby ennobles it. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [052]) | |
| A reaction: I take this to be an unusual way of saying that philosophy aims at the unification of knowledge, which is roughly my own view. It has hard for us to keep believing that life could be 'ennobled'. |
| 14885 | The first aim of a philosopher is a life, not some works [Nietzsche] |
| Full Idea: The philosopher's product is his life (first, before his works). It is his work of art. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 29 [205]) |
| 14887 | You should only develop a philosophy if you are willing to live by it [Nietzsche] |
| Full Idea: One should have a philosophy only to the extent that one is capable of living according to this philosophy: so that everything does not become mere words. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 30 [17]) |
| 14889 | Philosophy is pointless if it does not advocate, and live, a new way of life [Nietzsche] |
| Full Idea: As long as philosophers do not muster the courage to advocate a lifestyle structured in an entirely different way and demonstrate it by their own example, they will come to nothing. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 31 [10]) | |
| A reaction: This is a pretty tough requirement for the leading logicians and metaphysicians of our day, but they must face their marginality. The public will only be interested in philosophers who advocate new ways of living. |
| 14862 | Philosophy is more valuable than much of science, because of its beauty [Nietzsche] |
| Full Idea: The reason why unprovable philosophizing still has some value - more value, in fact, than many a scientific proposition - lies in the aesthetic value of such philosophizing, that is, in its beauty and sublimity. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [076]) | |
| A reaction: I am increasingly inclined to agree. I love wide-ranging and ambitious works of metaphysics, each of which is a unique creation of the human intellect (and with which no other individual will ever entirely agree). A great short paper is also beautiful. |
| 14876 | Philosophy is always secondary, because it cannot support a popular culture [Nietzsche] |
| Full Idea: It is not possible to base a popular culture on philosophy. Thus, with regard to culture, philosophy never can have primary, but always only secondary, significance. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 23 [14]) | |
| A reaction: It is the brilliance of Christianity as a set of ideas that it is simple enough to found a popular culture. A complex theology would make that impossible. Luther brought it back to its roots, when the priesthood lost touch with the people. |
| 14878 | It would better if there was no thought [Nietzsche] |
| Full Idea: It would be better if thought did not exist at all. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 29 [004]) |
| 14881 | Why do people want philosophers? [Nietzsche] |
| Full Idea: Why do human beings even want philosophers? | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 29 [019]) | |
| A reaction: It is not clear, of course, that they do want philosophers. The standard attitude to them seems to be a mixture of contempt and fear. |
| 14860 | Kant has undermined our belief in metaphysics [Nietzsche] |
| Full Idea: In a certain sense, Kant's influence was detrimental; for the belief in metaphysics has been lost. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [028]) | |
| A reaction: As I understand it, there are two interpretations of Kant, one of which is fairly thoroughly anti-metaphysical, and another which is less so. Also one path leads to idealism and the other doesn't, but I need to research that. |
| 14859 | If philosophy controls science, then it has to determine its scope, and its value [Nietzsche] |
| Full Idea: The philosophy that is in control of science must also consider the extent to which science should be allowed to develop; it must determine its value! | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [024]) |
| 10928 | Maybe we can quantify modally if the objects are intensional, but it seems unlikely [Quine] |
| Full Idea: Perhaps there is no objection to quantifying into modal contexts as long as the values of any variables thus quantified are limited to intensional objects, but they also lead to disturbing examples. | |
| From: Willard Quine (Reference and Modality [1953], §3) | |
| A reaction: [Quine goes on to give his examples] I take it that possibilities are features of actual reality, not merely objects of thought. The problem is that they are harder to know than actual objects. |
| 14880 | Logic is just slavery to language [Nietzsche] |
| Full Idea: Logic is merely slavery in the fetters of language. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 29 [008]) | |
| A reaction: I don't think I agree with this, but I still like it. |
| 10925 | Failure of substitutivity shows that a personal name is not purely referential [Quine] |
| Full Idea: Failure of substitutivity shows that the occurrence of a personal name is not purely referential. | |
| From: Willard Quine (Reference and Modality [1953], §1) | |
| A reaction: I don't think I understand the notion of a name being 'purely' referential, as if it somehow ceased to be a word, and was completely transparent to the named object. |
| 10926 | Quantifying into referentially opaque contexts often produces nonsense [Quine] |
| Full Idea: If to a referentially opaque context of a variable we apply a quantifier, with the intention that it govern that variable from outside the referentially opaque context, then what we commonly end up with is unintended sense or nonsense. | |
| From: Willard Quine (Reference and Modality [1953], §2) |
| 14869 | If some sort of experience is at the root of matter, then human knowledge is close to its essence [Nietzsche] |
| Full Idea: If pleasure, displeasure, sensation, memory, reflex movements are all part of the essence of matter, then human knowledge penetrates far more deeply into the essence of things. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [161]) | |
| A reaction: I don't think Nietzsche is thinking of monads at this point, but his idea certainly applies to them. Leibniz rested his whole theory on the close analogy between how minds work and how matter must also work. |
| 10930 | Quantification into modal contexts requires objects to have an essence [Quine] |
| Full Idea: A reversion to Aristotelian essentialism is required if quantification into modal contexts is to be insisted on. An object must be seen as having some of its traits necessarily. | |
| From: Willard Quine (Reference and Modality [1953], §3) | |
| A reaction: This thought leads directly to Kripke's proposal of rigid designation of objects (and Lewis response of counterparts), which really gets modal logic off the ground. Quine's challenge remains - the modal logic entails a huge metaphysical commitment. |
| 14645 | To be necessarily greater than 7 is not a trait of 7, but depends on how 7 is referred to [Quine] |
| Full Idea: To be necessarily greater than 7 is not a trait of a number, but depends on the manner of referring to the number. | |
| From: Willard Quine (Reference and Modality [1953], §2) | |
| A reaction: The most concise quotation of Quine's objection to 'de re' modality. The point is whether the number might have been referred to as 'the number of planets'. So many of these problems are solved by fixing unambiguous propositions first. |
| 9201 | Whether 9 is necessarily greater than 7 depends on how '9' is described [Quine, by Fine,K] |
| Full Idea: Quine's metaphysical argument is that if 9 is 7+2 the number 9 will be necessarily greater than 7, but when 9 is described as the number of planets, the number will not be necessarily greater than 7. The necessity depends on how it is described. | |
| From: report of Willard Quine (Reference and Modality [1953]) by Kit Fine - Intro to 'Modality and Tense' p. 3 | |
| A reaction: Thus necessity would be entirely 'de dicto' and not 'de re'. It sounds like a feeble argument. If I describe the law of identity (a=a) as 'my least favourite logical principle', that won't make it contingent. Describe 9, or refer to it? See Idea 9203. |
| 10927 | Necessity only applies to objects if they are distinctively specified [Quine] |
| Full Idea: Necessity does not properly apply to the fulfilment of conditions by objects (such as the number which numbers the planets), apart from special ways of specifying them. | |
| From: Willard Quine (Reference and Modality [1953], §3) | |
| A reaction: This appears to say that the only necessity is 'de dicto', and that there is no such thing as 'de re' necessity (of the thing in itself). How can Quine deny that there might be de re necessities? His point is epistemological - how can we know them? |
| 9203 | We can't quantify in modal contexts, because the modality depends on descriptions, not objects [Quine, by Fine,K] |
| Full Idea: 'Necessarily 9>7' may be true while the sentence 'necessarily the number of planets < 7' is false, even though it is obtained by substituting a coreferential term. So quantification in these contexts is unintelligible, without a clear object. | |
| From: report of Willard Quine (Reference and Modality [1953]) by Kit Fine - Intro to 'Modality and Tense' p. 4 | |
| A reaction: This is Quine's second argument against modality. See Idea 9201 for his first. Fine attempts to refute it. The standard reply seems to be to insist that 9 must therefore be an object, which pushes materialist philosophers into reluctant platonism. |
| 14875 | Belief matters more than knowledge, and only begins when knowledge ceases [Nietzsche] |
| Full Idea: The human being starts to believe when he ceases to know. …Knowledge is not as important for the welfare of human beings as is belief. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 21 [13]) | |
| A reaction: The first idea is now associated with Williamson (and Hossack). The second is something like the pragmatic view of belief espoused by Ramsey. |
| 14866 | It always remains possible that the world just is the way it appears [Nietzsche] |
| Full Idea: Against Kant we can still object, even if we accept all his propositions, that it is still possible that the world is as it appears to us. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [125]) | |
| A reaction: This little thought at least seems to be enough to block the slide from phenomenalism into total idealism. The idea that direct realism can never be ruled out, even if it is false, is very striking. |
| 14872 | Our knowledge is illogical, because it rests on false identities between things [Nietzsche] |
| Full Idea: Every piece of knowledge that is beneficial to us involves an identification of nonidentical things, of things that are similar, which means that it is essentially illogical. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [236]) | |
| A reaction: I take the thought to be that no two tigers are alike, but we call them all 'tigers' and merge them into a type, and then all our knowledge is based on this distortion. A wonderful idea. I love particulars You should love particulars. |
| 14879 | The most extreme scepticism is when you even give up logic [Nietzsche] |
| Full Idea: Even skepticism contains a belief: the belief in logic. The most extreme position is hence the abandoning of logic. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 29 [008]) | |
| A reaction: Some might say that flirting with non-classical logic (as in Graham Priest) is precisely travelling down this road. You could also be sceptical about meaning in language, so you couldn't articulate your abandonment of logic. |
| 14873 | If we find a hypothesis that explains many things, we conclude that it explains everything [Nietzsche] |
| Full Idea: The feeling of certainty is the most difficult to develop. Initially one seeks explanation: if a hypothesis explains many things, we draw the conclusion that it explains everything. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [238]) | |
| A reaction: As so often, a wonderful warning from Nietzsche to other philosophers. They love to latch onto a Big Idea, and offer it as the answer to everything (especially, dare I say it, continental philosophers). |
| 14868 | Our primary faculty is perception of structure, as when looking in a mirror [Nietzsche] |
| Full Idea: The primary faculty seems to me to be the perception of structure, that is, based upon the mirror. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [153]) | |
| A reaction: The point about the mirror makes this such an intriguingly original idea. Personally I like very much the idea that structure is our prime perception. See Sider 2011 on structure. |
| 14870 | We experience causation between willing and acting, and thereby explain conjunctions of changes [Nietzsche] |
| Full Idea: The only form of causality of which we are aware is that between willing and acting - we transfer this to all things, and thereby explain the relationship between two changes that always occur together. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [209]) | |
| A reaction: This is a rather Humean view, of projecting our experience onto the world, but it may be that we really are experiencing real causation, just as it occurs between insentiate things. |
| 14867 | It is just madness to think that the mind is supernatural (or even divine!) [Nietzsche] |
| Full Idea: To view 'spirit', the product of the brain, as supernatural. Even to deify it. What madness! | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [127]) | |
| A reaction: When I started philolosophy I was obliged to take mind-body dualism very seriously, but I have finally managed to drag myself to the shores of this lake of madness, where Nietzsche awaited with a helping hand. |
| 6017 | Nomos is king [Pindar] |
| Full Idea: Nomos is king. | |
| From: Pindar (poems [c.478 BCE], S 169), quoted by Thomas Nagel - The Philosophical Culture | |
| A reaction: This seems to be the earliest recorded shot in the nomos-physis wars (the debate among sophists about moral relativism). It sounds as if it carries the full relativist burden - that all that matters is what has been locally decreed. |
| 14884 | The shortest path to happiness is forgetfulness, the path of animals (but of little value) [Nietzsche] |
| Full Idea: If happiness were the goal, then animals would be the highest creatures. Their cynicism is grounded in forgetfulness: that is the shortest path to happiness, even if it is a happiness with little value. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 29 [143]) | |
| A reaction: I would be reluctant to describe an apparently contented cow as 'happy'. Is a comatose person happy? Maybe happiness is fulfilling one's nature, like a monkey swinging through trees? |
| 14886 | Education is contrary to human nature [Nietzsche] |
| Full Idea: Education runs contrary to the nature of a human being. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 30 [06]) | |
| A reaction: Tell me about it! |
| 14883 | We should evaluate the past morally [Nietzsche] |
| Full Idea: For the past I desire above all a moral evaluation. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 29 [096]) | |
| A reaction: There is a bit of a contradiction with Idea 14819, of only a few years later. He was always interested in a historical approach to morality, but I'm not sure if his ethics gives a decent basis for moral assessments of remote historical eras. |
| 14882 | Protest against vivisection - living things should not become objects of scientific investigation [Nietzsche] |
| Full Idea: Protest against vivisection of living things, that is, those things that are not yet dead should be allowed to live and not immediately be treated as an object for scientific investigation. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 29 [027]) | |
| A reaction: Wow. How many other people had come up with this idea in 1873? |
| 14865 | We do not know the nature of one single causality [Nietzsche] |
| Full Idea: We do not know the nature of one single causality. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [121]) |
| 14871 | Laws of nature are merely complex networks of relations [Nietzsche] |
| Full Idea: All laws of nature are only relations between x, y and z. We define laws of nature as relations to an x, y, and z, each of which in turn, is known to us only in relation to other x's, y's and z's. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [235]) | |
| A reaction: This could be interpreted in Armstrong's terms, as only identifying the x's, y's and z's by their universals, and then seeing laws as how those universal relate. I suspect, though, that Nietzsche has a Humean regularity pattern in mind. |
| 10931 | We can't say 'necessarily if x is in water then x dissolves' if we can't quantify modally [Quine] |
| Full Idea: To say an object is soluble in water is to say that it would dissolve if it were in water,..which implies that 'necessarily if x is in water then x dissolves'. Yet we do not know if there is a suitable sense of 'necessarily' into which we can so quantify. | |
| From: Willard Quine (Reference and Modality [1953], §4) | |
| A reaction: This is why there has been a huge revival of scientific essentialism - because Krike seems to offer exacty the account which Quine said was missing. So can you have modal logic without rigid designation? |
| 14864 | The Greeks lack a normative theology: each person has their own poetic view of things [Nietzsche] |
| Full Idea: The Greeks lack a normative theology: everyone has the right to deal with it in a poetic manner and he can believe whatever he wants. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [110]) | |
| A reaction: There is quite a lot of record of harshness towards atheists, and the trial of Socrates seems to have been partly over theology. However, no proper theological texts have come down, or records of the teachings of the priests. |
