| 2945 | Most philosophers start with reality and then examine knowledge; Descartes put the study of knowledge first [Lehrer] |
| Full Idea: Some philosophers (e.g Plato) begin with an account of reality, and then appended an account of how we can know it, ..but Descartes turned the tables, insisting that we must first decide what we can know. | |
| From: Keith Lehrer (Theory of Knowledge (2nd edn) [2000], I p.2) |
| 23183 | Different abilities are needed for living in an incomplete and undogmatic system [Nietzsche] |
| Full Idea: There is an entirely different strength and mobility to maintaining oneself in an incomplete system, with free, open vistas, than in a dogmatic world. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[025]) | |
| A reaction: This is like Keats's 'negative capability' - the ability to live in a state of uncertainty. I'm a fan of attempts to create a philosophical system, but dogmatism would seem to be the death of such a project. How would you live with your system? Nice. |
| 23188 | Bad writers use shapeless floating splotches of concepts [Nietzsche] |
| Full Idea: Bad writers have only shapeless floating splotches of concepts in their heads. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[083]) | |
| A reaction: Under 'conceptual analyis' not because he analyses concepts, but because he recognises their foundation importance in philosophy. I get more irritated by unchallenged concepts than by drifting concepts. Writer must know and challenge their key concepts. |
| 2946 | You cannot demand an analysis of a concept without knowing the purpose of the analysis [Lehrer] |
| Full Idea: An analysis is always relative to some objective. It makes no sense to simply demand an analysis of goodness, knowledge, beauty or truth, without some indication of the purpose of the analysis. | |
| From: Keith Lehrer (Theory of Knowledge (2nd edn) [2000], I p.7) | |
| A reaction: Your dismantling of a car will go better if you know what a car is for, but you can still take it apart in ignorance. |
| 23212 | A text has many interpretations, but no 'correct' one [Nietzsche] |
| Full Idea: The same text allows innumerable interpretations: there is no 'correct' interpretation. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 1[120]) | |
| A reaction: It is hard to defend a 'correct' interpretation, but I think it is obvious to students of literature that some interpretations are very silly, such as reading things allegorically when there was no such intention. |
| 23199 | What is the search for truth if it isn't moral? [Nietzsche] |
| Full Idea: What is searching for truth, truthfulness, honesty if not something moral? | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 35[05]) | |
| A reaction: Feels right to me. It might be an effect of the virtue of respect. If you respect a person you tell them the truth (assuming they want the truth). Lying to someone is a sort of contempt. |
| 23202 | Like all philosophers, I love truth [Nietzsche] |
| Full Idea: I, too, love truth, like all philosophers. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 37[02]) | |
| A reaction: Please pay attention to this remark! His perspectivalism is not a denial of truth. It is an epistemological phenomenon, not a metaphysical one. The perspectives are the nearest we can get to truth. Humanity therefore needs teamwork. |
| 5745 | Quine says quantified modal logic creates nonsense, bad ontology, and false essentialism [Melia on Quine] |
| Full Idea: Quine charges quantified modal systems of logic with giving rise to unintended sense or nonsense, committing us to an incomprehensible ontology, and entailing an implausible or unsustainable Aristotelian essentialism. | |
| From: comment on Willard Quine (Existence and Quantification [1966]) by Joseph Melia - Modality Ch.3 | |
| A reaction: A nice summary. Personally I like essentialism in accounts of science (see Nature|Laws of Nature|Essentialism), so would like to save it in metaphysics. Possible worlds ontology may be very surprising, rather than 'incomprehensible'. |
| 8789 | Various strategies try to deal with the ontological commitments of second-order logic [Hale/Wright on Quine] |
| Full Idea: Quine said higher-order logic is 'set theory in sheep's clothing', and there is concern about the ontology that is involved. One approach is to deny quantificational ontological commitments, or say that the entities involved are first-order objects. | |
| From: comment on Willard Quine (Existence and Quantification [1966]) by B Hale / C Wright - Logicism in the 21st Century 8 | |
| A reaction: [compressed] The second strategy is from Boolos. This question seems to be right at the heart of the strategy of exploring our ontology through the study of our logic. |
| 23196 | Logic is a fiction, which invents the view that one thought causes another [Nietzsche] |
| Full Idea: The model of a complete fiction is logic. Here a thinking is made up where a thought is posited as the cause of another thought. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[249]) | |
| A reaction: He could almost be referring to Frege's Third Realm. Most hard core analytic philosophers seem to think that propositions have tight logical relationships which are nothing to do with the people who think them. |
| 23186 | Numbers enable us to manage the world - to the limits of counting [Nietzsche] |
| Full Idea: Numbers are our major means of making the world manageable. We comprehend as far as we can count, i.e. as far as a constancy can be perceived. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[058]) | |
| A reaction: I don't agree with 'major', but it is a nice thought. The intermediate concept is a 'unit', which means identifying something as a 'thing', which is how we seem to grasp the world. So to what extent do we comprehend the infinite. Enter Cantor… |
| 16966 | Philosophers tend to distinguish broad 'being' from narrower 'existence' - but I reject that [Quine] |
| Full Idea: It has been fairly common in philosophy early and late to distinguish between being, as the broadest concept, and existence, as narrower. This is no distinction of mine; I mean 'exist' to cover all there is. | |
| From: Willard Quine (Existence and Quantification [1966], p.100) | |
| A reaction: I sort of agree with Quine, but 'being' has a role in philosophy that is not required in science and daily life, as the name of the central problem of ontology, which probably has to be broken down before any progress can happen. |
| 16965 | All we have of general existence is what existential quantifiers express [Quine] |
| Full Idea: Existence is what existential quantification expresses. …It is unreasonable to ask for an explication of (general) existence in simpler terms. …We may still ask what counts as evidence for existential quantifications. | |
| From: Willard Quine (Existence and Quantification [1966], p.97) | |
| A reaction: This has been orthodoxy for the last 60 years, with philosophers talking of 'quantifying over' instead of 'exists'. But are we allowed second-order logic, and plural quantification, and vague domains? |
| 23211 | Events are just interpretations of groups of appearances [Nietzsche] |
| Full Idea: There is no event in itself. What happens is a group of appearances selected and summarised by an interpreting being. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 1[115]) | |
| A reaction: Since innumerable events are nested within one another, such as the events at a carnival, this is obviously true. A primitive 'Kim event' (an object changes a property) might have objective existence. Carnivals happen, though. |
| 16963 | Existence is implied by the quantifiers, not by the constants [Quine] |
| Full Idea: In the quantification '(∃)(x=a)', it is the existential quantifier, not the 'a' itself, which carries the existential import. | |
| From: Willard Quine (Existence and Quantification [1966], p.94) | |
| A reaction: The Fregean idea seems to be that the criterion of existence is participation in an equality, but here the equality seems not more than assigning a name. Why can't I quantify over 'sakes', in 'for the sake of the children'? |
| 16964 | Theories are committed to objects of which some of its predicates must be true [Quine] |
| Full Idea: Another way of saying what objects a theory requires is to say that they are the objects that some of the predicates of the theory have to be true of, in order for the theory to be true. | |
| From: Willard Quine (Existence and Quantification [1966], p.95) | |
| A reaction: The other was for the objects to be needed by the bound variables of the theory. This is the first-order approach, that predication is a commitment to an object. So what of predicates which have no application? |
| 4216 | Express a theory in first-order predicate logic; its ontology is the types of bound variable needed for truth [Quine, by Lowe] |
| Full Idea: According to Quine, we find the ontological commitments of a theory by expressing it in first-order predicate logic, then determining what kind of entities must be admitted as bound variables if the theory is true. | |
| From: report of Willard Quine (Existence and Quantification [1966]) by E.J. Lowe - A Survey of Metaphysics p.216 | |
| A reaction: To me this is horribly wrong. The ontological commitments of our language is not the same as ontology. What are the ontological commitments of a pocket calculator? |
| 18966 | Ontological commitment of theories only arise if they are classically quantified [Quine] |
| Full Idea: I hold that the question of the ontological commitment of a theory does not properly arise except as that theory is expressed in classical quantificational form. | |
| From: Willard Quine (Existence and Quantification [1966], p.106) | |
| A reaction: He is attacking substitutional quantification for its failure to commit. I smell circularity. If it must be quantified in the first-order classical manner, that restricts your ontology to objects before you've even started. Chicken/egg. |
| 14490 | You can be implicitly committed to something without quantifying over it [Thomasson on Quine] |
| Full Idea: Quine's test for ontological commitment ignores the fact that there are often implicit commitments to certain kinds of entities even where we are not yet quantifying over them. | |
| From: comment on Willard Quine (Existence and Quantification [1966]) by Amie L. Thomasson - Ordinary Objects 09.4 | |
| A reaction: Put this with the obvious problem (of which Quine is aware) that we don't quantify over 'sakes' in 'for the sake of the children', and quantification and commitment have been rather clearly pulled apart. |
| 16961 | In formal terms, a category is the range of some style of variables [Quine] |
| Full Idea: In terms of formalized quantification theory, each category comprises the range of some distinctive style of variable. | |
| From: Willard Quine (Existence and Quantification [1966], p.92) | |
| A reaction: I add this for those who dream of formalising everything, but be warned that even Quine thought it of little help in deciding on the categories. Presumably there would be some variable that ranged across tigers. |
| 23201 | The 'I' does not think; it is a construction of thinking, like other useful abstractions [Nietzsche] |
| Full Idea: I do not grant to the metaphysicians that the 'I' is what thinks: on the contrary I take the I itself as a construction thinking, of the same rank as 'material',' thing', 'substance', 'purpose', 'number': therefore only as a regulative fiction. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 35[35]) | |
| A reaction: Ah. I have always defended the Self, the thing that is in charge when the mind is directed to something. I suddenly see that this is compatible with the Self not being the thinker! It is just the willer, and the controller of the searchlight. Self = will? |
| 23207 | Appearance is the sole reality of things, to which all predicates refer [Nietzsche] |
| Full Idea: Appearance as I understand it is the actual and single reality of things - that which first merits all existing predicates. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 40[53]) | |
| A reaction: This is the view espoused by John Stuart Mill (a fact which would shock Nietzsche!). Elsewhere he laughs at the concept of the thing-in-itself as a fiction. |
| 23197 | Memory is essential, and is only possible by means of abbreviation signs [Nietzsche] |
| Full Idea: Experience is only possible with the help of memory; memory is only possible by virtue of an abbreviation of an intellectual event as a sign. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[249]) | |
| A reaction: My memory of a town is not formed as a sign, but as a bunch of miscellaneous fragments about it. I think mental files gives a better account of this than do 'signs'. |
| 23206 | Schematic minds think thoughts are truer if they slot into a scheme [Nietzsche] |
| Full Idea: There are schematic minds, those who hold a thought-complex to be truer if it can be sketched into previously drafted schemata or categorical tables. There are countless self-deceptions in this area: nearly all the great 'systems' belong here. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 40[09]) | |
| A reaction: Why 'nearly all'? Aristotle might be a candidate for such a person. Leibniz, perhaps. Nietzsche identified with Becoming and Heraclitus, as opposed to Being and Parmenides. |
| 23209 | Each of our personal drives has its own perspective [Nietzsche] |
| Full Idea: From the standpoint of each of our fundamental drives there is a different perspectival assessment of all events and experiences. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 1[058]) | |
| A reaction: Revealing. Perspectives are not just each individual person's viewpoint, but something more fine-grained than that. Our understanding and response are ambiguous, because we ourselves are intrinsically ambiguous. Super-relativism! |
| 23184 | The mind is a simplifying apparatus [Nietzsche] |
| Full Idea: The intellect and the senses are above all a simplifying apparatus. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[046]) | |
| A reaction: Very plausible, and not an idea I have met elsewhere. There's a PhD here for someone. It fits with my view as universals in language (which is most of language), which capture diverse things by ironing out their differences. |
| 23190 | Consciousness is our awareness of our own mental life [Nietzsche] |
| Full Idea: We have a double brain: our capacity to will, to feel and to think of our willing, feeling, thinking ourselves is what we summarise with the word 'consciousness'. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[087]) | |
| A reaction: Pretty much the modern HOT (higher order thought) theory of consciousness. Higher order thought distinguishes us from the other animals, but I think they too are probably conscious, so I don't agree. Why is level 2 conscious of level 1? |
| 23191 | Minds have an excluding drive to scare things off, and a selecting one to filter facts [Nietzsche] |
| Full Idea: In our conscious intellect there must be an excluding drive that scares things away, a selecting one, which only permits certain facts to present themselves. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[131]) | |
| A reaction: I like this because he is endorsing the idea that philosophy needs faculties, which may not match the views of psychologists and neuroscientists. Quite nice to think of faculties as drives. |
| 23213 | The greatest drive of life is to discharge strength, rather than preservation [Nietzsche] |
| Full Idea: Something that lives wants above all to discharge its strength: 'preservation' is only one of the consequences of this. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 2[063]) | |
| A reaction: This seems to fit a dynamic man like Nietzsche, rather than someone who opts for a quiet and comfortable life. |
| 23210 | That all events are necessary does not mean they are compelled [Nietzsche] |
| Full Idea: The absolute necessity of all events contains nothing of a compulsion. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 1[114]) | |
| A reaction: I like to look for necessity-makers behind necessities. So if the event is not necessary because of its cause, where does it come from? Is it that the whole sequence is a unified necessity? |
| 23189 | Concepts are rough groups of simultaneous sensations [Nietzsche] |
| Full Idea: Concepts are more or less definite groups of sensations that arrive together. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[086]) | |
| A reaction: I like this because I favour accounts of concepts which root them in experience, and largely growing unthinking out of communcal experience. Nietzsche is very empirical here. Hume would probably agree. |
| 23192 | Concepts don’t match one thing, but many things a little bit [Nietzsche] |
| Full Idea: A concept is an invention that doesn't correspond entirely to anything; but to many things a little bit. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[131]) | |
| A reaction: This seems to cover some concepts quite well, but others not at all. What else does 'square' correspond to? |
| 23187 | Whatever their origin, concepts survive by being useful [Nietzsche] |
| Full Idea: The most useful concepts have survived: however falsely they may have originated. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[063]) | |
| A reaction: The germ of both pragmatism, and of meaning-as-use, here. The alternative views must be that the concepts are accurate or true, or that they are simply a matter of whim, maintained by authority. |
| 23205 | Thought starts as ambiguity, in need of interpretation and narrowing [Nietzsche] |
| Full Idea: A thought in the shape in which it comes is an ambiguous sign that needs interpretation, more precisely, needs an arbitrary narrowing-down and limitation, until it finally becomes unambiguous. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 38[01]) | |
| A reaction: This is exactly my view of propositions, as mental events. Introspect your thinking process. Track the progress from the first glimmer of a thought to its formulation in a finished sentence. Language, unlike propositions, can be ambiguous. |
| 23198 | Aesthetics can be more basic than morality, in our pleasure in certain patterns of experience [Nietzsche] |
| Full Idea: Some of the aesthetic valuations are more fundamental than the moral ones e.g. the pleasure in what is ordered, surveyable, limited, in repetition. The logical, arithmetical and geometrical good feelings form the ground floor of aesthetic valuations. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 35[02]) | |
| A reaction: Nietzsche's originality is so striking because his novel suggestions are always plausible. Lots of modern philosophers (especially, I fear, in the continental tradition) throw out startling ideas which then fail on closer inspection. |
| 23208 | Caesar and Napoleon point to the future, when they pursue their task regardless of human sacrifice [Nietzsche] |
| Full Idea: In nature's such as Caesar and Napoleon we intuit something of a 'disinterested' laboring on one's marble, regardless of any sacrifice of human beings. The future of the highest human beings lies on here: to bear responsibility and not collapse under it. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 1[056]) | |
| A reaction: Hideous. Nietzsche at his absolute worst. You would think there was some wonderful higher good to which they were leading the human race, when they just strike me as people who liked fighting, and adored winning. |
| 23193 | Napoleon was very focused, and rightly ignored compassion [Nietzsche] |
| Full Idea: With Napoleon only the essential instincts of humanity came into consideration during his calculations, and he had a right not to take notice of the exceptional ones e.g. of compassion. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[131]) | |
| A reaction: Napoleon was notoriously indifferent to casualties, and I find it depressing that Nietzsche supports him. Napoleon brought misery to Europe for nearly twenties, mainly because he loved winning battles. Nothing über about that. |
| 23214 | For the strongest people, nihilism gives you wings! [Nietzsche] |
| Full Idea: In the hands of the strongest every kind of pessimism and nihilism becomes only one more hammer and tool with which one mounts a new pair of wings on oneself. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 2[101]) | |
| A reaction: Not sure how this works. Why is great strength needed? Strength implies forceful overcoming. The wings come from rejecting nihilism, but why does that need strength? Aren't there people with wings who never even thought of nihilism? |
| 23203 | The great question is approaching, of how to govern the earth as a whole [Nietzsche] |
| Full Idea: It is approaching, irrefutably, hesitatingly, terrible as fate, the great task and fate: how should the earth as a whole be governed? | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 37[08]) | |
| A reaction: Two issues have accelerated the question, though we have yet to properly face it. One is the incredible increase in military destructiveness, and other is the damage to the planet caused by the relentless pursuit of wealth. |
| 23200 | The controlling morality of aristocracy is the desire to resemble their ancestors [Nietzsche] |
| Full Idea: The foundation of all aristocracies …is to resemble the ancestors as much as possible, which serves as the controlling morality: mourning at the thought of change and variation. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 35[22]) | |
| A reaction: This makes sense of the permanent residence of the family, full of portraits and family trees. Aristocrats preserve records of their predecessors, in a way that most of us don't, going back before grandparents. |
| 23194 | People feel united as a nation by one language, but then want a common ancestry and history [Nietzsche] |
| Full Idea: People who speak one language and read the same newspapers today call themselves 'nations', and also want much too eagerly to be of common ancestry and history. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[203]) | |
| A reaction: This sort of nationalism is still with us, as white supremacy, and as history as mythology. But we can't just shake off a sense of which gene pools we come from, and which lines of history are our personal inheritance. |
| 23204 | To be someone you need property, and wanting more is healthy [Nietzsche] |
| Full Idea: Property owners are to a man of one belief: 'you have to own something to be something'. But this is the oldest and healthiest of all instincts: I would add 'you have to want more than you have in order to become more'. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 37[11]) | |
| A reaction: An odd idea from someone who spent his later years living in one room in a guest house. The context of this is a rejection of socialism. The love of and need for property and possessions must be taken into account in any politics. |
| 23195 | Laws of nature are actually formulas of power relations [Nietzsche] |
| Full Idea: The alleged 'laws of nature' are formulas for power relationships… | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[247]) | |
| A reaction: Love it. This is precisely the powers ontology of modern philosophy of science. His Will to Power is not often recognised as closely related to this view. |
| 23185 | In chemistry every substance pushes, and thus creates new substances [Nietzsche] |
| Full Idea: In chemistry is revealed that every substance pushes its force as far as it can, then a third something emerges. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 34[51]) | |
| A reaction: This is the ontology of powers as the basis of science, of which I am a fan. It is Nietzsche's Will to Power in action, which is often mistakenly taken to only refer to human affairs. |
