87 ideas
| 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. |
| 13860 | We can only learn from philosophers of the past if we accept the risk of major misrepresentation [Wright,C] |
| Full Idea: We can learn from the work of philosophers of other periods only if we are prepared to run the risk of radical and almost inevitable misrepresentation of his thought. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], Pref) | |
| A reaction: This sounds about right, and a motto for my own approach to Aristotle and Leibniz, but I see the effort as more collaborative than this suggests. Professional specialists in older philosophers are a vital part of the team. Read them! |
| 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) |
| 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) |
| 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) |
| 13883 | The best way to understand a philosophical idea is to defend it [Wright,C] |
| Full Idea: The most productive way in which to attempt an understanding of any philosophical idea is to work on its defence. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 1.vii) | |
| A reaction: Very nice. The key point is that this brings greater understanding than working on attacking an idea, which presumably has the dangers of caricature, straw men etc. It is the Socratic insight that dialectic is the route to wisdom. |
| 10142 | The attempt to define numbers by contextual definition has been revived [Wright,C, by Fine,K] |
| Full Idea: Frege gave up on the attempt to introduce natural numbers by contextual definition, but the project has been revived by neo-logicists. | |
| From: report of Crispin Wright (Frege's Concept of Numbers as Objects [1983]) by Kit Fine - The Limits of Abstraction II |
| 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) |
| 9868 | An expression refers if it is a singular term in some true sentences [Wright,C, by Dummett] |
| Full Idea: For Wright, an expression refers to an object if it fulfils the 'syntactic role' of a singular term, and if we have fixed the truth-conditions of sentences containing it in such a way that some of them come out true. | |
| From: report of Crispin Wright (Frege's Concept of Numbers as Objects [1983]) by Michael Dummett - Frege philosophy of mathematics Ch.15 | |
| A reaction: Much waffle is written about reference, and it is nice to hear of someone actually trying to state the necessary and sufficient conditions for reference to be successful. So is it possible for 'the round square' to ever refer? '...is impossible to draw' |
| 13861 | Number theory aims at the essence of natural numbers, giving their nature, and the epistemology [Wright,C] |
| Full Idea: In the Fregean view number theory is a science, aimed at those truths furnished by the essential properties of zero and its successors. The two broad question are then the nature of the objects, and the epistemology of those facts. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], Intro) | |
| A reaction: [compressed] I pounce on the word 'essence' here (my thing). My first question is about the extent to which the natural numbers all have one generic essence, and the extent to which they are individuals (bless their little cotton socks). |
| 13892 | One could grasp numbers, and name sizes with them, without grasping ordering [Wright,C] |
| Full Idea: Someone could be clear about number identities, and distinguish numbers from other things, without conceiving them as ordered in a progression at all. The point of them would be to make comparisons between sizes of groups. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 3.xv) | |
| A reaction: Hm. Could you grasp size if you couldn't grasp which of two groups was the bigger? What's the point of noting that I have ten pounds and you only have five, if you don't realise that I have more than you? You could have called them Caesar and Brutus. |
| 13867 | Instances of a non-sortal concept can only be counted relative to a sortal concept [Wright,C] |
| Full Idea: The invitation to number the instances of some non-sortal concept is intelligible only if it is relativised to a sortal. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 1.i) | |
| A reaction: I take this to be an essentially Fregean idea, as when we count the boots when we have decided whether they fall under the concept 'boot' or the concept 'pair'. I also take this to be the traditional question 'what units are you using'? |
| 17441 | Wright thinks Hume's Principle is more fundamental to cardinals than the Peano Axioms are [Wright,C, by Heck] |
| Full Idea: Wright is claiming that HP is a special sort of truth in some way: it is supposed to be the fundamental truth about cardinality; ...in particular, HP is supposed to be more fundamental, in some sense than the Dedekind-Peano axioms. | |
| From: report of Crispin Wright (Frege's Concept of Numbers as Objects [1983]) by Richard G. Heck - Cardinality, Counting and Equinumerosity 1 | |
| A reaction: Heck notes that although PA can be proved from HP, HP can be proven from PA plus definitions, so direction of proof won't show fundamentality. He adds that Wright thinks HP is 'more illuminating'. |
| 13862 | There are five Peano axioms, which can be expressed informally [Wright,C] |
| Full Idea: Informally, Peano's axioms are: 0 is a number, numbers have a successor, different numbers have different successors, 0 isn't a successor, properties of 0 which carry over to successors are properties of all numbers. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], Intro) | |
| A reaction: Each statement of the famous axioms is slightly different from the others, and I have reworded Wright to fit him in. Since the last one (the 'induction axiom') is about properties, it invites formalization in second-order logic. |
| 17853 | Number truths are said to be the consequence of PA - but it needs semantic consequence [Wright,C] |
| Full Idea: The intuitive proposal is the essential number theoretic truths are precisely the logical consequences of the Peano axioms, ...but the notion of consequence is a semantic one...and it is not obvious that we possess a semantic notion of the requisite kind. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], Intro) | |
| A reaction: (Not sure I understand this, but it is his starting point for rejecting PA as the essence of arithmetic). |
| 17854 | What facts underpin the truths of the Peano axioms? [Wright,C] |
| Full Idea: We incline to think of the Peano axioms as truths of some sort; so there has to be a philosophical question how we ought to conceive of the nature of the facts which make those statements true. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], Intro) | |
| A reaction: [He also asks about how we know the truths] |
| 13894 | Sameness of number is fundamental, not counting, despite children learning that first [Wright,C] |
| Full Idea: We teach our children to count, sometimes with no attempt to explain what the sounds mean. Doubtless it is this habit which makes it so natural to think of the number series as fundamental. Frege's insight is that sameness of number is fundamental. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 3.xv) | |
| A reaction: 'When do children understand number?' rather than when they can recite numerals. I can't make sense of someone being supposed to understand number without a grasp of which numbers are bigger or smaller. To make 13='15' do I add or subtract? |
| 10140 | We derive Hume's Law from Law V, then discard the latter in deriving arithmetic [Wright,C, by Fine,K] |
| Full Idea: Wright says the Fregean arithmetic can be broken down into two steps: first, Hume's Law may be derived from Law V; and then, arithmetic may be derived from Hume's Law without any help from Law V. | |
| From: report of Crispin Wright (Frege's Concept of Numbers as Objects [1983]) by Kit Fine - The Limits of Abstraction I.4 | |
| A reaction: This sounds odd if Law V is false, but presumably Hume's Law ends up as free-standing. It seems doubtful whether the resulting theory would count as logic. |
| 8692 | Frege has a good system if his 'number principle' replaces his basic law V [Wright,C, by Friend] |
| Full Idea: Wright proposed removing Frege's basic law V (which led to paradox), replacing it with Frege's 'number principle' (identity of numbers is one-to-one correspondence). The new system is formally consistent, and the Peano axioms can be derived from it. | |
| From: report of Crispin Wright (Frege's Concept of Numbers as Objects [1983]) by Michčle Friend - Introducing the Philosophy of Mathematics 3.7 | |
| A reaction: The 'number principle' is also called 'Hume's principle'. This idea of Wright's resurrected the project of logicism. The jury is ought again... Frege himself questioned whether the number principle was a part of logic, which would be bad for 'logicism'. |
| 17440 | Wright says Hume's Principle is analytic of cardinal numbers, like a definition [Wright,C, by Heck] |
| Full Idea: Wright intends the claim that Hume's Principle (HP) embodies an explanation of the concept of number to imply that it is analytic of the concept of cardinal number - so it is an analytic or conceptual truth, much as a definition would be. | |
| From: report of Crispin Wright (Frege's Concept of Numbers as Objects [1983]) by Richard G. Heck - Cardinality, Counting and Equinumerosity 1 | |
| A reaction: Boolos is quoted as disagreeing. Wright is claiming a fundamental truth. Boolos says something can fix the character of something (as yellow fixes bananas), but that doesn't make it 'fundamental'. I want to defend 'fundamental'. |
| 13893 | It is 1-1 correlation of concepts, and not progression, which distinguishes natural number [Wright,C] |
| Full Idea: What is fundamental to possession of any notion of natural number at all is not the knowledge that the numbers may be arrayed in a progression but the knowledge that they are identified and distinguished by reference to 1-1 correlation among concepts. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 3.xv) | |
| A reaction: My question is 'what is the essence of number?', and my inclination to disagree with Wright on this point suggests that the essence of number is indeed caught in the Dedekind-Peano axioms. But what of infinite numbers? |
| 13888 | If numbers are extensions, Frege must first solve the Caesar problem for extensions [Wright,C] |
| Full Idea: Identifying numbers with extensions will not solve the Caesar problem for numbers unless we have already solved the Caesar problem for extensions. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 3.xiv) |
| 13869 | Number platonism says that natural number is a sortal concept [Wright,C] |
| Full Idea: Number-theoretic platonism is just the thesis that natural number is a sortal concept. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 1.i) | |
| A reaction: See Crispin Wright on sortals to expound this. An odd way to express platonism, but he is presenting the Fregean version of it. |
| 13870 | We can't use empiricism to dismiss numbers, if numbers are our main evidence against empiricism [Wright,C] |
| Full Idea: We may not be able to settle whether some general form of empiricism is correct independently of natural numbers. It might be precisely our grasp of the abstract sortal, natural number, which shows the hypothesis of empiricism to be wrong. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 1.i) | |
| A reaction: A nice turning of the tables. In the end only coherence decides these things. You may accept numbers and reject empiricism, and then find you have opened the floodgates for abstracta. Excessive floodgates, or blockages of healthy streams? |
| 13873 | Treating numbers adjectivally is treating them as quantifiers [Wright,C] |
| Full Idea: Treating numbers adjectivally is, in effect, treating the numbers as quantifiers. Frege observes that we can always parse out any apparently adjectival use of a number word in terms of substantival use. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 1.iii) | |
| A reaction: The immediate response to this is that any substantival use can equally be expressed adjectivally. If you say 'the number of moons of Jupiter is four', I can reply 'oh, you mean Jupiter has four moons'. |
| 13899 | The Peano Axioms, and infinity of cardinal numbers, are logical consequences of how we explain cardinals [Wright,C] |
| Full Idea: The Peano Axioms are logical consequences of a statement constituting the core of an explanation of the notion of cardinal number. The infinity of cardinal numbers emerges as a consequence of the way cardinal number is explained. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 4.xix) | |
| A reaction: This, along with Idea 13896, nicely summarises the neo-logicist project. I tend to favour a strategy which starts from ordering, rather than identities (1-1), but an attraction is that this approach is closer to counting objects in its basics. |
| 13896 | The aim is to follow Frege's strategy to derive the Peano Axioms, but without invoking classes [Wright,C] |
| Full Idea: We shall endeavour to see whether it is possible to follow through the strategy adumbrated in 'Grundlagen' for establishing the Peano Axioms without at any stage invoking classes. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 4.xvi) | |
| A reaction: The key idea of neo-logicism. If you can avoid classes entirely, then set theory paradoxes become irrelevant, and classes aren't logic. Philosophers now try to derive the Peano Axioms from all sorts of things. Wright admits infinity is a problem. |
| 7804 | Wright has revived Frege's discredited logicism [Wright,C, by Benardete,JA] |
| Full Idea: Crispin Wright has reactivated Frege's logistic program, which for decades just about everybody assumed was a lost cause. | |
| From: report of Crispin Wright (Frege's Concept of Numbers as Objects [1983]) by José A. Benardete - Logic and Ontology 3 | |
| A reaction: [This opens Bernadete's section called "Back to Strong Logicism?"] |
| 13863 | Logicism seemed to fail by Russell's paradox, Gödel's theorems, and non-logical axioms [Wright,C] |
| Full Idea: Most would cite Russell's paradox, the non-logical character of the axioms which Russell and Whitehead's reconstruction of Frege's enterprise was constrained to employ, and the incompleteness theorems of Gödel, as decisive for logicism's failure. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], Intro) |
| 13895 | The standard objections are Russell's Paradox, non-logical axioms, and Gödel's theorems [Wright,C] |
| Full Idea: The general view is that Russell's Paradox put paid to Frege's logicist attempt, and Russell's own attempt is vitiated by the non-logical character of his axioms (esp. Infinity), and by the incompleteness theorems of Gödel. But these are bad reasons. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 4.xvi) | |
| A reaction: Wright's work is the famous modern attempt to reestablish logicism, in the face of these objections. |
| 13884 | The idea that 'exist' has multiple senses is not coherent [Wright,C] |
| Full Idea: I have the gravest doubts whether any coherent account could be given of any multiplicity of senses of 'exist'. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 2.x) | |
| A reaction: I thoroughly agree with this thought. Do water and wind exist in different senses of 'exist'? |
| 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'. |
| 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) |
| 13877 | Singular terms in true sentences must refer to objects; there is no further question about their existence [Wright,C] |
| Full Idea: When a class of terms functions as singular terms, and the sentences are true, then those terms genuinely refer. Being singular terms, their reference is to objects. There is no further question whether they really refer, and there are such objects. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 1.iii) | |
| A reaction: This seems to be a key sentence, because this whole view is standardly called 'platonic', but it certainly isn't platonism as we know it, Jim. Ontology has become an entirely linguistic matter, but do we then have 'sakes' and 'whereaboutses'? |
| 9878 | Contextually defined abstract terms genuinely refer to objects [Wright,C, by Dummett] |
| Full Idea: Wright says we should accord to contextually defined abstract terms a genuine full-blown reference to objects. | |
| From: report of Crispin Wright (Frege's Concept of Numbers as Objects [1983]) by Michael Dummett - Frege philosophy of mathematics Ch.18 | |
| A reaction: This is the punch line of Wright's neo-logicist programme. See Idea 9868 for his view of reference. Dummett regards this strong view of contextual definition as 'exorbitant'. Wright's view strikes me as blatantly false. |
| 13868 | Sortal concepts cannot require that things don't survive their loss, because of phase sortals [Wright,C] |
| Full Idea: The claim that no concept counts as sortal if an instance of it can survive its loss, runs foul of so-called phase sortals like 'embryo' and 'chrysalis'. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 1.i) | |
| A reaction: The point being that those items only fall under that sortal for one phase of their career, and of their identity. I've always thought such claims absurd, and this gives a good reason for my view. |
| 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) |
| 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. |
| 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. |
| 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? |
| 3238 | 'Dead person' isn't a contradiction, so 'person' is somewhat vague [Williams,B] |
| Full Idea: If we say (in opposition to a physical view of identity) that when Jones dies 'Jones ceases to exist' but 'Jones' body does not cease to exist', this shouldn't be pressed too hard, because it would make 'dead person' a contradiction. | |
| From: Bernard Williams (Are Persons Bodies? [1970], p.74) | |
| A reaction: A good point, which nicely challenges the distinction between a 'human' and a 'person', but the problem case is much more the one where Jones gets advanced Alzheimer's, rather than dies. A dead body ceases as a mechanism, as well as as a personality. |
| 3239 | You can only really love a person as a token, not as a type [Williams,B] |
| Full Idea: If you love a person as a type instead of as a token (i.e. a "person", instead of a physical body) you might prefer a run-down copy of them to no person at all, but at this point our idea of loving a person begins to crack. | |
| From: Bernard Williams (Are Persons Bodies? [1970], p.81) | |
| A reaction: Very persuasive. If you love a person you can cope with them getting old. If you own an original watercolour, you can accept that it fades, but you would replace a reproduction of it if that faded. But what, then, is it that you love? |
| 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) |
| 13866 | A concept is only a sortal if it gives genuine identity [Wright,C] |
| Full Idea: Before we can conclude that φ expresses a sortal concept, we need to ensure that 'is the same φ as' generates statements of genuine identity rather than of some other equivalence relation. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 1.i) |
| 13865 | 'Sortal' concepts show kinds, use indefinite articles, and require grasping identities [Wright,C] |
| Full Idea: A concept is 'sortal' if it exemplifies a kind of object. ..In English predication of a sortal concept needs an indefinite article ('an' elm). ..What really constitutes the distinction is that it involves grasping identity for things which fall under it. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 1.i) | |
| A reaction: This is a key notion, which underlies the claims of 'sortal essentialism' (see David Wiggins). |
| 13890 | Entities fall under a sortal concept if they can be used to explain identity statements concerning them [Wright,C] |
| Full Idea: 'Tree' is not a sortal concept under which directions fall since we cannot adequately explain the truth-conditions of any identity statement involving a pair of tree-denoting singular terms by appealing to facts to do with parallelism between lines. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 3.xiv) | |
| A reaction: The idea seems to be that these two fall under 'hedgehog', because that is a respect in which they are identical. I like to notion of explanation as a part of this. |
| 13898 | If we can establish directions from lines and parallelism, we were already committed to directions [Wright,C] |
| Full Idea: The fact that it seems possible to establish a sortal notion of direction by reference to lines and parallelism, discloses tacit commitments to directions in statements about parallelism...There is incoherence in the idea that a line might lack direction. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 4.xviii) | |
| A reaction: This seems like a slippery slope into a very extravagant platonism about concepts. Are concepts like direction as much a part of the natural world as rivers are? What other undiscovered concepts await us? |
| 13882 | A milder claim is that understanding requires some evidence of that understanding [Wright,C] |
| Full Idea: A mild version of the verification principle would say that it makes sense to think of someone as understanding an expression only if he is able, by his use of the expression, to give the best possible evidence that he understands it. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 1.vii) | |
| A reaction: That doesn't seem to tell us what understanding actually consists of, and may just be the truism that to demonstrate anything whatsoever will necessarily involve some evidence. |
| 13885 | If apparent reference can mislead, then so can apparent lack of reference [Wright,C] |
| Full Idea: If the appearance of reference can be misleading, why cannot an apparent lack of reference be misleading? | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 2.xi) | |
| A reaction: A nice simple thought. Analytic philosophy has concerned itself a lot with sentences that seem to refer, but the reference can be analysed away. For me, this takes the question of reference out of the linguistic sphere, which wasn't Wright's plan. |
| 17857 | We can accept Frege's idea of object without assuming that predicates have a reference [Wright,C] |
| Full Idea: The heart of the problem is Frege's assumption that predicates have Bedeutungen at all; and no reason is at present evident why someone who espouses Frege's notion of object is contrained to make that assumption. | |
| From: Crispin Wright (Frege's Concept of Numbers as Objects [1983], 1.iv) | |
| A reaction: This seems like a penetrating objection to Frege's view of reference, and presumably supports the Kripke approach. |
| 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. |
| 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. |
| 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) |
| 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) |
| 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) |
