40 ideas
| 24146 | All the major problems were formulated before Socrates [Nietzsche] |
| Full Idea: All the major problems were formulated before Socrates. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 26[064]) | |
| A reaction: So much for it all being 'footnotes to Plato'! Nietzsche's lectures on the pre-Socratics are in print. Given how little survives, this idea is surprising. Nietzsche knew enough to infer a lot of what is lost. |
| 24142 | What matters is how humans can be developed [Nietzsche] |
| Full Idea: What can be made out of humans: this is what matters to superior human beings. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[435]) | |
| A reaction: That seems to sum up the main aim of Nietzsche's philosophy. What would we then do if the aim was somehow achieved? Does he seriously think that one magnificent ubermensch could achieve this aim? |
| 24143 | Thinkers might agree some provisional truths, as methodological assumptions [Nietzsche] |
| Full Idea: It is sufficient if we [thinkers] come to agree about a totality of methodological presuppositions - about 'provisional truths' that we want to use as a guideline for our work. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[449]) | |
| A reaction: Descartes attempted this. Maybe Frege is another attempt. Husserl, perhaps? Parmenides? Hume? Lewis? It is hard to imagine Nietzsche joining in a professional consensus! He has just rejected systems. |
| 24125 | Aristotle enjoyed the sham generalities of a system, as the peak of happiness! [Nietzsche] |
| Full Idea: Aristotle probably had his best moments when he coldly and clearly (and joyfully) enjoyed the sensual sham of the highest generalities. To perceive the world as a system, and as the pinnacle of human happiness: how the schematic mind betrays itself then! | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[017]) | |
| A reaction: Painful, this. One of my heroes laughing at the other one. I love systems, and love John Richardson's suggestion that Nietzsche was very systematice, despite his protestations. |
| 24147 | Thoughts are uncertain, and are just occasions for interpretation [Nietzsche] |
| Full Idea: A thought is not taken to be immediately certain, but rather a sign, a question mark. That each thought is initially ambiguous and fluctuating, and is in itself only an occasion for multiple interpretations …is experienced by every deep observer. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 26[092]) | |
| A reaction: This idea makes me a little more sympathetic to the hermeneutic view of philosophy, as endless interpretations. I assumed it only referred to texts. A thought is not a done deal, but an occasion for further thought. He says the same of feelings. |
| 18755 | Validity is explained as truth in all models, because that relies on the logical terms [McGee] |
| Full Idea: A model of a language assigns values to non-logical terms. If a sentence is true in every model, its truth doesn't depend on those non-logical terms. Hence the validity of an argument comes from its logical form. Thus models explain logical validity. | |
| From: Vann McGee (Logical Consequence [2014], 4) | |
| A reaction: [compressed] Thus you get a rigorous account of logical validity by only allowing the rigorous input of model theory. This is the modern strategy of analytic philosophy. But is 'it's red so it's coloured' logically valid? |
| 24137 | Mathematics is just accurate inferences from definitions, and doesn't involve objects [Nietzsche] |
| Full Idea: Mathematics contains axioms (definitions) and conclusions from definitions. Its objects do not exist. The truth of its conclusions rests on the accuracy of logical thought. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[307]) | |
| A reaction: Not suprising to find Nietzsche defying platonism. This is evidence that he was a systematic philosopher, who knew mathematics could be a challenge to his naturalism. |
| 18751 | Natural language includes connectives like 'because' which are not truth-functional [McGee] |
| Full Idea: Natural language includes connectives that are not truth-functional. In order for 'p because q' to be true, both p and q have to be true, but knowing the simpler sentences are true doesn't determine whether the larger sentence is true. | |
| From: Vann McGee (Logical Consequence [2014], 2) |
| 18761 | Second-order variables need to range over more than collections of first-order objects [McGee] |
| Full Idea: To get any advantage from moving to second-order logic, we need to assign to second-order variables a role different from merely ranging over collections made up of things the first-order variables range over. | |
| From: Vann McGee (Logical Consequence [2014], 7) | |
| A reaction: Thus it is exciting if they range over genuine properties, but not so exciting if you merely characterise those properties as sets of first-order objects. This idea leads into a discussion of plural quantification. |
| 18753 | An ontologically secure semantics for predicate calculus relies on sets [McGee] |
| Full Idea: We can get a less ontologically perilous presentation of the semantics of the predicate calculus by using sets instead of concepts. | |
| From: Vann McGee (Logical Consequence [2014], 4) | |
| A reaction: The perilous versions rely on Fregean concepts, and notably Russell's 'concept that does not fall under itself'. The sets, of course, have to be ontologically secure, and so will involve the iterative conception, rather than naive set theory. |
| 18754 | Logically valid sentences are analytic truths which are just true because of their logical words [McGee] |
| Full Idea: Logically valid sentences are a species of analytic sentence, being true not just in virtue of the meanings of their words, but true in virtue of the meanings of their logical words. | |
| From: Vann McGee (Logical Consequence [2014], 4) | |
| A reaction: A helpful link between logical truths and analytic truths, which had not struck me before. |
| 18757 | Soundness theorems are uninformative, because they rely on soundness in their proofs [McGee] |
| Full Idea: Soundness theorems are seldom very informative, since typically we use informally, in proving the theorem, the very same rules whose soundness we are attempting to establish. | |
| From: Vann McGee (Logical Consequence [2014], 5) | |
| A reaction: [He cites Quine 1935] |
| 18760 | The culmination of Euclidean geometry was axioms that made all models isomorphic [McGee] |
| Full Idea: One of the culminating achievements of Euclidean geometry was categorical axiomatisations, that describe the geometric structure so completely that any two models of the axioms are isomorphic. The axioms are second-order. | |
| From: Vann McGee (Logical Consequence [2014], 7) | |
| A reaction: [He cites Veblen 1904 and Hilbert 1903] For most mathematicians, categorical axiomatisation is the best you can ever dream of (rather than a single true axiomatisation). |
| 24131 | There is no 'being'; it is just the opposition to nothingness [Nietzsche] |
| Full Idea: 'Being' is unprovable, because there is no 'being'. The concept of being is formed out of the opposition to 'nothingness'. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[185]) | |
| A reaction: Presumably a comment on Hegel's most basic idea. I find both thoughts bewildering. 'Being' is just a generalised (and unhelpful) way of referring to the self-evident existence of stuff. |
| 24151 | I only want thinking that is anchored in body, senses and earth [Nietzsche] |
| Full Idea: I am not interested …in ways of thinking that are not anchored in the body and the senses and in the earth. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 26[352]) | |
| A reaction: Exhibit A for Nietzsche as Naturalist. Indeed, this could be a manifesto for the whole school. I totally and completely and utterly agree with Nietzsche's assertion!. I see the 'anchor' as two-way: thought connects to earth, and thought arises from it. |
| 7566 | The Identity of Indiscernibles is really the same as the verification principle [Jolley] |
| Full Idea: Various writers have noted that the Identity of Indiscernibles is really tantamount to the verification principle. | |
| From: Nicholas Jolley (Leibniz [2005], Ch.3) | |
| A reaction: Both principles are false, because they are the classic confusion of epistemology and ontology. The fact that you cannot 'discern' a difference between two things doesn't mean that there is no difference. Things beyond verification can still be discussed. |
| 24150 | We can only understand through concepts, which subsume particulars in generalities [Nietzsche] |
| Full Idea: We have only one form of understanding - concept, the more general case that subsumes the particular case. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 26[156]) | |
| A reaction: This is precisely Aristotle's problem with scientific explanation - that we aim to understand each particular, but accounts and definitions have to be expressed with universals. |
| 24138 | Strongly believed a priori is not certain; it may just be a feature of our existence [Nietzsche] |
| Full Idea: What we believe the most, everything a priori, is not for that reason more certain, just because it is so strongly believed. Rather, it is perhaps a consequence of the condition for the existence of our species. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[307]) | |
| A reaction: This is in defiance of Leibniz and Kant. His proposed explanation is not very convincing. Russell agreed with Nietzsche. |
| 24130 | An affirmative belief is present in every basic sense impression [Nietzsche] |
| Full Idea: Belief is already present in every sense impression going back to the very moment it begins: a kind of Yes-saying first intellectual activity! | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[168]) | |
| A reaction: He seems right that there is an intrinsic commitment to believing sense impressions, even in animals. Presumably more of a default setting than an intellectual choice. |
| 24124 | We now have innumerable perspectives to draw on [Nietzsche] |
| Full Idea: We have been granted perspectives in all directions, broader than any humans have ever been granted, everywhere we look there is no end in sight. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[013]) | |
| A reaction: Clearly perspectivism is not the simple relativism of being trapped in our own private perspective. What strikes me as missing from Nietzsche's brief thoughts is the question of consensus, and even rational and objective consensus. |
| 24145 | Mind is a mechanism of abstraction and simplification, aimed at control [Nietzsche] |
| Full Idea: The entire cognitive mechanism is a mechanism of abstraction and simplification - not aimed at knowing, but taking control of things. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 26[061]) | |
| A reaction: It is my view that we can explain our metaphysics in this way, though I am more realist than Nietzsche, because I think the world has created these capacities within us, so they fit the world. To control, you must know. |
| 24144 | A cognitive mechanism wanting to know itself is absurd! [Nietzsche] |
| Full Idea: A cognitive mechanism that wants to know itself!! We definitely should have moved beyond this absurd goal! (The stomach that consumes itself! -) | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 26[018]) | |
| A reaction: We see his point, but Nietzsche learns a huge amount about himself by introspection. To know the Self is a cat chasing its tail. I don't have to leave England to study England. |
| 24139 | A 'person' is just one possible abstraction from a bundle of qualities [Nietzsche] |
| Full Idea: Individuals contain many more persons than they think. 'Person' is merely a point of emphasis, synopsis of characteristics and qualities | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[363]) | |
| A reaction: He makes similar remarks abour character. For Locke 'person'' is a forensic and legal concept, and so must be enduring and unique. |
| 24133 | I have perfected fatalism, as recurrence and denial of the will [Nietzsche] |
| Full Idea: I have perfected fatalism, through eternal recurrence and preexistence, and through the elimination of the concept 'will'. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[214]) | |
| A reaction: 'Amor fati' - love of fate - was his oft repeated slogan. We can all understand 'go with the flow', but I'm not sure about anything more universal than that. |
| 24152 | Fate is inspiring, if you understand you are part of it [Nietzsche] |
| Full Idea: Fate is an inspiring thought for those who understand that they are part of it. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 26[442]) | |
| A reaction: Sounds a bit like the Niagara Falls being inspiring if you are being swept over it. I find the possibility of fatalism neutral, rather than inspiring. |
| 24129 | We start with images, then words, and then concepts, to which emotions attach [Nietzsche] |
| Full Idea: Images first, the words applied to images. Finally concepts, not possible until there are words a summary of many images. When see similar images for which there is one word - this weak emotion is the common element, the foundation of the concept. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[168]) | |
| A reaction: Unusual to have an account of the origin of concepts in 1884. His theory entails that animals can't have concepts, but presumably they can combine images, and hence recognise things. I think he is wrong, but interestng. Mental files. |
| 18762 | A maxim claims that if we are allowed to assert a sentence, that means it must be true [McGee] |
| Full Idea: If our linguistic conventions entitle us to assert a sentence, they thereby make it true, because of the maxim that 'truth is the norm of assertion'. | |
| From: Vann McGee (Logical Consequence [2014], 8) | |
| A reaction: You could only really deny that maxim if you had no belief at all in truth, but then you can assert anything you like (with full entitlement). Maybe you can assert anything you like as long as it doesn't upset anyone? Etc. |
| 24127 | Judging actions by intentions - like judging painters by their thoughts! [Nietzsche] |
| Full Idea: To judge people by intentions! That would be like classifying artists, not according to their paintings, but according to their visions! | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[119]) | |
| A reaction: What is wrong is to judge an action by any simple single principle. Our nuanced attitude to excuses shows the true complexity of it. 'I didn't mean to do that'. |
| 24149 | Values need a perspective, of preserving some aspect of life [Nietzsche] |
| Full Idea: All value judgements involve a particular perspective: preservation of the individual, a community, a race, a state, a church, a belief, a culture. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 26[119]) | |
| A reaction: This chimes in with my Aristotelian view of value, as arising out of the thing valued, rather than descending on it from outside. I think more than mere 'preservaation' is at stake. Fostering, cherishing. |
| 24148 | If you love something, it is connected with everything, so all must be affirmed as good [Nietzsche] |
| Full Idea: To appreciate and love anything, I must understand it as absolutely necessarily connected with everything that is - therefore I must affirm the goodness of all existence for its own sake. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 26[117]) | |
| A reaction: For those of you out there imagining that Nietzsche was a nihilist…… It's a plausible idea. You could hardly love your dog, but hate the whole universe. A true misanthrope would struggle to love one exceptional person. |
| 24135 | Egoism should not assume that all egos are equal [Nietzsche] |
| Full Idea: Egoism! But no one has ever asked: what kind of ego! Instead, every person automatically assumes that the ego of every ego is equal. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[287]) | |
| A reaction: The implication, I presume, is that you should be egoistic if you have a really excellent ego, but very altruistic if you are a loser. Or a slave. Or a monk. |
| 24132 | After Socrates virtue is misunderstood, as good for all, not for individuals [Nietzsche] |
| Full Idea: From Socrates onwards arete [virtue] is misunderstood - first it had to reestablish itself over and over, and yet it did not want to do this on an individual basis! But rather tyrannically 'good for all!'. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[208]) | |
| A reaction: Why not both? The virtues of a good citizen can't be private, but we are all allowed to develop virtues that concern us alone. |
| 24126 | We contain multitudes of characters, which can brought into the open [Nietzsche] |
| Full Idea: There is a multitude of characters hidden within each one of us: and attempts should be made to allow some of them to appear. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[021]) | |
| A reaction: So character is not fate, contrary to Heraclitus (his hero). We are more inclined now to see varied characters as social roles (as in Irving Goffman). This idea challenges it, with our intrinsic nature containing variety. |
| 24136 | Who can endure the thought of eternal recurrence? [Nietzsche] |
| Full Idea: I conduct the great test: who will endure the thought of eternal recurrence? | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[290]) | |
| A reaction: He sometimes talks as if eternal recurrence were a cosmic fact, but we should definitely ignore that. This idea captures his idea best, I think - that we should try to live with the prospect of recurrence always in mind. A type of existentialism. |
| 24154 | If you want one experience repeated, you must want all of them [Nietzsche] |
| Full Idea: Whoever wants to have a single experience again must want all of them again. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 29[054]) | |
| A reaction: Nehemas says this is the main factual commitment of eternal recurrence (and certainly not that global recurrence actually occurs). It might be expressed in terms of possible worlds. We yearn for recurrence, then dread it? |
| 24153 | Humans are determined by community, so its preservation is their most valued drive [Nietzsche] |
| Full Idea: If a community is what absolutely determines the nature of humans, then the drive that allows the community to be preserved will be most forcefully developed in them. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 27[030]) | |
| A reaction: Nietzsche was a loner, who despised 'the herd' and its dull 'good and evil', but humans are obviously social creatures, who need to raise families, so it seems perverse to despise the values this requires. Note the Marxist view of human nature. |
| 24134 | There is always slavery, whether we like it or not [Nietzsche] |
| Full Idea: In truth there is always slavery - whether you want it or not; e.g. Prussian officials. Scholars. Monks. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[225]) | |
| A reaction: Not very persuasive examples. Monks are free to join and to leave. Maybe a lot of marriages are close to slavery for one side (usually the woman). Strict slavery has almost ceased in western civilisation (I think!). Nietzsche saw 'the herd' as slaves. |
| 24128 | After history following God, or a people, or an idea, we now see it in terms of animals [Nietzsche] |
| Full Idea: Earlier we sought God's intentions in history: then an unconscious purposefulness, in a people or an idea. Only recently are we considering the history of animals, and the first insight is that no plan has so far existed. Coincidences have been dominant. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[127]) | |
| A reaction: Not a Whig historian then! Presumably Hegel is his main target. In 2024 there is a definite feeling that western democracies are regressing. |
| 24140 | Cause and effect is a hypothesis, based on our supposed willing of actions [Nietzsche] |
| Full Idea: Cause and effect is not a truth but rather a hypothesis - and indeed the one which we use to anthropomorphise the world for ourselves, bringing it in closer proximity to our feelings ('willing' is projected into it). | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[371]) | |
| A reaction: That is (I think), we read the gap between thought and action onto natural external events, dividing them up. We treat the flow of events as if they were agent causation. Modern theories seem close to Nietzsche's unified view. |
| 24141 | Having a sense of time presupposes absolute time [Nietzsche] |
| Full Idea: Our derivation of the sense of time etc. still presupposes time as absolute. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[406]) | |
| A reaction: 'Etc.'? I suppose this is meant to pre-empt whatever Bergson might have been planning to say. The idea that time actually is subjective strikes as very wrong. Whether physicists can reduce time to something else is above my pay scale. |
