| 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| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 30 [25]) |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| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [086]) | |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| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 32 [67]) | |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| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [052]) | |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| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 29 [205]) |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| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 30 [17]) |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. |
| 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. |
| 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. |
| 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]) |
| 18915 | If facts are the truthmakers, they are not in the world [Engelbretsen] |
| Full Idea: If there are such things as truthmakers (facts), they are not to be found in the world. As Strawson would say to Austin: there is the cat, there is the mat, but where in the world is the fact that the cat is on the mat? | |
| From: George Engelbretsen (Trees, Terms and Truth [2005], 4) | |
| A reaction: He cites Strawson, Quine and Davidson for this point. |
| 18919 | There are no 'falsifying' facts, only an absence of truthmakers [Engelbretsen] |
| Full Idea: A false proposition is not made false by anything like a 'falsifying' fact. A false proposition simply fails to be made true by any fact. | |
| From: George Engelbretsen (Trees, Terms and Truth [2005], 4) | |
| A reaction: Sounds good. In truthmaker theory, one truth-value (T) is 'made', but the other one is not, so there is no symmetry between the two. Better to talk of T and not-T? See ideas on Excluded Middle. |
| 18913 | Traditional term logic struggled to express relations [Engelbretsen] |
| Full Idea: The greatest challenge for traditional term logicians was the proper formulation and treatment of relational expressions. | |
| From: George Engelbretsen (Trees, Terms and Truth [2005]) | |
| A reaction: The modern term logic of Fred Sommers claims to have solved this problem. |
| 18907 | Term logic rests on negated terms or denial, and that propositions are tied pairs [Engelbretsen] |
| Full Idea: That terms can be negated, that such negation is distinguishable from denial, and that propositions can be construed syntactically as predicationally tied pairs of terms, are important for the tree theory of predication, and for term logic. | |
| From: George Engelbretsen (Trees, Terms and Truth [2005], 2) |
| 18912 | Was logic a branch of mathematics, or mathematics a branch of logic? [Engelbretsen] |
| Full Idea: Nineteenth century logicians debated whether logic should be treated simply as a branch of mathematics, and mathematics could be applied to it, or whether mathematics is a branch of logic, with no mathematics used in formulating logic. | |
| From: George Engelbretsen (Trees, Terms and Truth [2005], 3) | |
| A reaction: He cites Boole, De Morgan and Peirce for the first view, and Frege and Russell (and their 'logicism') for the second. The logic for mathematics slowly emerged from doing it, long before it was formalised. Mathematics is the boss? |
| 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. |
| 18922 | Logical syntax is actually close to surface linguistic form [Engelbretsen] |
| Full Idea: The underlying logical syntax of language is close to the surface syntax of ordinary language. | |
| From: George Engelbretsen (Trees, Terms and Truth [2005], 5) | |
| A reaction: This is the boast of the Term logicians, in opposition to the strained and unnatural logical forms of predicate logic, which therefore don't give a good account of the way ordinary speakers reason. An attractive programme. 'Terms' are the key. |
| 18905 | Propositions can be analysed as pairs of terms glued together by predication [Engelbretsen] |
| Full Idea: Sommers's 'tree theory' of predication assumes that propositions can be analysed as pairs of terms joined by some kind of predicational glue. | |
| From: George Engelbretsen (Trees, Terms and Truth [2005], 2) | |
| A reaction: This is the basis of Sommers's upgraded Aristotelian logic, known as Term Logic. The idea of reasoning with 'terms', rather than with objects, predicates and quantifiers, seems to me very appealing. I think I reason more about facts than about objects. |
| 18908 | Standard logic only negates sentences, even via negated general terms or predicates [Engelbretsen] |
| Full Idea: Standard logic recognises only one kind of negation: sentential negation. Consequently, negation of a general term/predicate always amounts to negation of the entire sentence. | |
| From: George Engelbretsen (Trees, Terms and Truth [2005], 3) |
| 18917 | Existence and nonexistence are characteristics of the world, not of objects [Engelbretsen] |
| Full Idea: Existence and nonexistence are not primarily properties of individual objects (dogs, unicorns), but of totalities. To say that some object exists is just to say that it is a constituent of the world, which is a characteristic of the world, not the object. | |
| From: George Engelbretsen (Trees, Terms and Truth [2005], 4) | |
| A reaction: This has important implications for the problem of truthmakers for negative existential statements (like 'there are no unicorns'). It is obviously a relative of Armstrong's totality facts that do the job. Not sure about 'a characteristic of'. |
| 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. |
| 18916 | Facts are not in the world - they are properties of the world [Engelbretsen] |
| Full Idea: Facts must be viewed as properties of the world - not as things in the world. | |
| From: George Engelbretsen (Trees, Terms and Truth [2005], 4) | |
| A reaction: Not sure I'm happy with either of these. Do animals grasp facts? If not, are they (as Strawson said) just the truths expressed by true sentences? That is not a clear idea either, given that facts are not the sentences themselves. Facts overlap. |
| 18921 | Individuals are arranged in inclusion categories that match our semantics [Engelbretsen] |
| Full Idea: The natural categories of individuals are arranged in a hierarchy of inclusion relations that is isomorphic with the linguistic semantic structure. | |
| From: George Engelbretsen (Trees, Terms and Truth [2005], 5) | |
| A reaction: This is the conclusion of a summary of modern Term Logic. The claim is that Sommers discerned this structure in our semantics (via the study of 'terms'), and was pleasantly surprised to find that it matched a plausible structure of natural categories. |
| 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. |
| 18918 | Terms denote objects with properties, and statements denote the world with that property [Engelbretsen] |
| Full Idea: In term logic, what a term denotes are the objects having the property it signifies. What a statement denotes is the world, that which has the constitutive property it signifies. | |
| From: George Engelbretsen (Trees, Terms and Truth [2005], 4) |
| 18920 | 'Socrates is wise' denotes a sentence; 'that Socrates is wise' denotes a proposition [Engelbretsen] |
| Full Idea: Whereas 'Socrates is wise' denotes a sentence, 'that Socrates is wise' denotes a proposition. | |
| From: George Engelbretsen (Trees, Terms and Truth [2005], 4) | |
| A reaction: In traditional parlance, 'reported speech' refers to the underlying proposition, because it does not commit to the actual words being used. As a lover of propositions (as mental events, not mysterious abstract objects), I like this. |
| 18906 | Negating a predicate term and denying its unnegated version are quite different [Engelbretsen] |
| Full Idea: There is a crucial distinction in term logic between affirming a negated predicate term of some subject and denying the unnegated version of that term of that same subject. We must distinguish 'X is non-P' from 'X is not P'. | |
| From: George Engelbretsen (Trees, Terms and Truth [2005], 2) | |
| A reaction: The first one affirms something about X, but the second one just blocks off a possible description of X. 'X is non-harmful' and 'X is not harmful' - if X had ceased to exist, the second would be appropriate and the first wouldn't? I'm guessing. |
| 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? |
| 5049 | Intelligent pleasure is the perception of beauty, order and perfection [Leibniz] |
| Full Idea: An intelligent being's pleasure is simply the perception of beauty, order and perfection. | |
| From: Gottfried Leibniz (A Résumé of Metaphysics [1697], §18) | |
| A reaction: Leibniz seems to have inherited this from the Greeks, especially Pythagoras and Plato. Buried in Leibniz's remark I see the Christian fear of physical pleasure. He should have got out more. Must an intelligent being always be intelligent? |
| 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. |
| 5048 | Perfection is simply quantity of reality [Leibniz] |
| Full Idea: Perfection is simply quantity of reality. | |
| From: Gottfried Leibniz (A Résumé of Metaphysics [1697], §11) | |
| A reaction: An interesting claim, but totally beyond my personal comprehension. I presume he inherited 'quantity of reality' from Plato, e.g. as you move up the Line from shadows to Forms you increase the degree of reality. I see 'real' as all-or-nothing. |
| 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. |
| 5050 | Evil serves a greater good, and pain is necessary for higher pleasure [Leibniz] |
| Full Idea: Evils themselves serve a greater good, and the fact that pains are found in minds is necessary if they are to reach greater pleasures. | |
| From: Gottfried Leibniz (A Résumé of Metaphysics [1697], §23) | |
| A reaction: How much pain is needed to qualify for the 'greater pleasures'? Some people receive an awful lot. I am not sure exactly how an evil can 'serve' a greater good. Is he recommending evil? |
