| 7834 | Great philosophies are confessions by the author, growing out of moral intentions [Nietzsche] |
| Full Idea: It has gradually become clear to me what every great philosophy has hitherto been: a confession on the part of its author, and a kind of involuntary and unconscious memoir, ...with moral intentions being the real germ of its life. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §006) | |
| A reaction: This attitude is what places Nietzsche as the parent of post-modernism, and is the reason why most 'continental' philosophers seem to have given up the attempt to simply reason about life. It is anti-Enlightenment, and it is wicked. |
| 7080 | Metaphysics divided the old unified Greek world into two [Nietzsche, by Critchley] |
| Full Idea: Nietzsche famously defines metaphysics as the division of one world into two; the unity of the mythical pre-philosophical experience of the world is sundered, with Plato, into being and seeming, reality and appearance, supersensible and sensible. | |
| From: report of Friedrich Nietzsche (Beyond Good and Evil [1886]) by Simon Critchley - Continental Philosophy - V. Short Intro | |
| A reaction: (Critchley doesn't give a reference; Idea 2860 is close). This is the discredited status that metaphysics gradually acquired after Kant, but I see modern metaphysics as reuniting human thought by digging down to the foundations to reveal roots and links. |
| 7807 | The laws of thought are true, but they are not the axioms of logic [Bolzano, by George/Van Evra] |
| Full Idea: Bolzano said the 'laws of thought' (identity, contradiction, excluded middle) are true, but nothing of interest follows from them. Logic obeys them, but they are not logic's first principles or axioms. | |
| From: report of Bernard Bolzano (Theory of Science (Wissenschaftslehre, 4 vols) [1837], §3) by George / Van Evra - The Rise of Modern Logic | |
| A reaction: An interesting and crucial distinction. For samples of proposed axioms of logic, see Ideas 6408, 7798 and 7797. |
| 11090 | Why do we want truth, rather than falsehood or ignorance? The value of truth is a problem [Nietzsche] |
| Full Idea: What really is it in us that wants 'the truth'? ...Granted we want truth: why not rather untruth? And uncertainty? Even ignorance? The problem of the value of truth stepped before us. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §001) | |
| A reaction: I think this is one of the great moments in philosophy, when something that has been taken for granted, as a kind of mantra, is suddenly looked in the face and challenged. Truth at all costs? What sacrifices would you make for truth? |
| 11211 | If a sound conclusion comes from two errors that cancel out, the path of the argument must matter [Rumfitt] |
| Full Idea: If a designated conclusion follows from the premisses, but the argument involves two howlers which cancel each other out, then the moral is that the path an argument takes from premisses to conclusion does matter to its logical evaluation. | |
| From: Ian Rumfitt ("Yes" and "No" [2000], II) | |
| A reaction: The drift of this is that our view of logic should be a little closer to the reasoning of ordinary language, and we should rely a little less on purely formal accounts. |
| 11210 | Standardly 'and' and 'but' are held to have the same sense by having the same truth table [Rumfitt] |
| Full Idea: If 'and' and 'but' really are alike in sense, in what might that likeness consist? Some philosophers of classical logic will reply that they share a sense by virtue of sharing a truth table. | |
| From: Ian Rumfitt ("Yes" and "No" [2000]) | |
| A reaction: This is the standard view which Rumfitt sets out to challenge. |
| 11212 | The sense of a connective comes from primitively obvious rules of inference [Rumfitt] |
| Full Idea: A connective will possess the sense that it has by virtue of its competent users' finding certain rules of inference involving it to be primitively obvious. | |
| From: Ian Rumfitt ("Yes" and "No" [2000], III) | |
| A reaction: Rumfitt cites Peacocke as endorsing this view, which characterises the logical connectives by their rules of usage rather than by their pure semantic value. |
| 9618 | Bolzano wanted to reduce all of geometry to arithmetic [Bolzano, by Brown,JR] |
| Full Idea: Bolzano if the father of 'arithmetization', which sought to found all of analysis on the concepts of arithmetic and to eliminate geometrical notions entirely (with logicism taking it a step further, by reducing arithmetic to logic). | |
| From: report of Bernard Bolzano (Theory of Science (Wissenschaftslehre, 4 vols) [1837]) by James Robert Brown - Philosophy of Mathematics Ch. 3 | |
| A reaction: Brown's book is a defence of geometrical diagrams against Bolzano's approach. Bolzano sounds like the modern heir of Pythagoras, if he thinks that space is essentially numerical. |
| 9830 | Bolzano began the elimination of intuition, by proving something which seemed obvious [Bolzano, by Dummett] |
| Full Idea: Bolzano began the process of eliminating intuition from analysis, by proving something apparently obvious (that as continuous function must be zero at some point). Proof reveals on what a theorem rests, and that it is not intuition. | |
| From: report of Bernard Bolzano (Theory of Science (Wissenschaftslehre, 4 vols) [1837]) by Michael Dummett - Frege philosophy of mathematics Ch.6 | |
| A reaction: Kant was the target of Bolzano's attack. Two responses might be to say that many other basic ideas are intuited but impossible to prove, or to say that proof itself depends on intuition, if you dig deep enough. |
| 7079 | Nietzsche resists nihilism through new values, for a world of becoming, without worship [Nietzsche, by Critchley] |
| Full Idea: Nietzsche's work is a resistance to nihilism. This is why he insists that new categories and values are required that would permit us to endure this world of becoming without either falling into despair or inventing some new god and bowing before it. | |
| From: report of Friedrich Nietzsche (Beyond Good and Evil [1886]) by Simon Critchley - Continental Philosophy - V. Short Intro | |
| A reaction: The trouble is that all Nietzsche offers is the invention of values out of nothing by some wretched Germanic übermensch who is obsessed with militarism and dominance. If values don't grow out of human nature, then 'all is permitted'. |
| 17265 | Philosophical proofs in mathematics establish truths, and also show their grounds [Bolzano, by Correia/Schnieder] |
| Full Idea: Mathematical proofs are philosophical in method if they do not only demonstrate that a certain mathematical truth holds but if they also disclose why it holds, that is, if they uncover its grounds. | |
| From: report of Bernard Bolzano (Theory of Science (Wissenschaftslehre, 4 vols) [1837]) by Correia,F/Schnieder,B - Grounding: an opinionated introduction 2.3 | |
| A reaction: I aim to defend the role of explanation in mathematics, but this says that this is only if the proofs are 'philosophical', which may be of no interest to mathematicians. Oh well, that's their loss. |
| 2878 | We see an approximation of a tree, not the full detail [Nietzsche] |
| Full Idea: We do not see a tree exactly and entire with regard to its leaves, branches, colour and shape; it is so much easier for us to see an approximation of a tree. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §192) |
| 9185 | Bolzano wanted to avoid Kantian intuitions, and prove everything that could be proved [Bolzano, by Dummett] |
| Full Idea: Bolzano was determined to expel Kantian intuition from analysis, and to prove from first principles anything that could be proved, no matter how obvious it might seem when thought of in geometrical terms. | |
| From: report of Bernard Bolzano (Theory of Science (Wissenschaftslehre, 4 vols) [1837]) by Michael Dummett - The Philosophy of Mathematics 2.3 | |
| A reaction: This is characteristic of the Enlightenment Project, well after the Enlightenment. It is a step towards Frege's attack on 'psychologism' in mathematics. The problem is that it led us into a spurious platonism. We live in troubled times. |
| 20140 | We shouldn't object to a false judgement, if it enhances and preserves life [Nietzsche] |
| Full Idea: The falseness of a judgement is to us not necessarily an objection to a judgement. To what extent is it life-advancing, life-preserving, species-preserving. Our fundamental tendency is to assert that our falsest judgements are the most indispensable. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §004) | |
| A reaction: This is the standard objection to pragmatism, that what is false may still be useful, and that clever blighter Nietzsche embraces the idea! |
| 2877 | Morality becomes a problem when we compare many moralities [Nietzsche] |
| Full Idea: The real problems of morality come into view only if we compare many moralities. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §186) |
| 20355 | The ranking of a person's innermost drives reveals their true nature [Nietzsche] |
| Full Idea: To know 'who he is', we must know the order of rank the innermost drives of his nature stand in relative to one another. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §006) | |
| A reaction: This is clearly an essentialist view of a person, as having a 'nature', which is 'inner', and which we can try to specify. Ranking drives and values seems a good proposal for getting at it. I'm also intrigued by what people find interesting. |
| 2291 | A thought comes when 'it' wants, not when 'I' want [Nietzsche] |
| Full Idea: A thought comes when 'it' wants, not when 'I' want. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §017) | |
| A reaction: A wonderful remark (which I have since found in Schopenhauer). I don't see how the most enthusiastic free will libertarian can deny it. |
| 2871 | Wanting 'freedom of will' is wanting to pull oneself into existence out of the swamp of nothingness by one's own hair [Nietzsche] |
| Full Idea: The desire for 'freedom of will' is nothing less than the desire to pull oneself into existence out of the swamp of nothingness by one's own hair. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §021) |
| 20381 | It is psychology which reveals the basic problems [Nietzsche] |
| Full Idea: Psychology is now once again the road to the fundamental problems. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §023) | |
| A reaction: This may become the epigraph of my great book, which will have as working title 'The Psychology of Metaphysics'. If you trawl through this collection, you will see where I am going! (A tough job, but easier than reading Hegel). |
| 22276 | Bolzano saw propositions as objective entities, existing independently of us [Bolzano, by Potter] |
| Full Idea: Bolzano took the entities of which truth is predicated to be not propositions in the subjective sense but 'propositions-in-themselves' - objective entities existing independent of our apprehension. | |
| From: report of Bernard Bolzano (Theory of Science (Wissenschaftslehre, 4 vols) [1837]) by Michael Potter - The Rise of Analytic Philosophy 1879-1930 02 'Emp' | |
| A reaction: A serious mistake. Presumably the objective propositions are all true (or there would be endless infinities of them). So what is assessed in the case of error? Something other than the objective propositions! We assess these other things! |
| 17264 | Propositions are abstract structures of concepts, ready for judgement or assertion [Bolzano, by Correia/Schnieder] |
| Full Idea: Bolzano conceived of propositions as abstract objects which are structured compounds of concepts and potential contents of judgements and assertions. | |
| From: report of Bernard Bolzano (Theory of Science (Wissenschaftslehre, 4 vols) [1837]) by Correia,F/Schnieder,B - Grounding: an opinionated introduction 2.3 | |
| A reaction: Personally I think of propositions as brain events, the constituents of thought about the world, but that needn't contradict the view of them as 'abstract'. |
| 12232 | A 'proposition' is the sense of a linguistic expression, and can be true or false [Bolzano] |
| Full Idea: What I mean by 'propositions' is not what the grammarians call a proposition, namely the linguistic expression, but the mere sense of this expression, is what is meant by proposition in itself or object proposition. This sense can be true or false. | |
| From: Bernard Bolzano (Theory of Science (Wissenschaftslehre, 4 vols) [1837], Pref?) | |
| A reaction: This seems to be the origin of what we understand by 'proposition'. The disputes are over whether such things exists, and whether they are features of minds or features of the world (resembling facts). |
| 12233 | The ground of a pure conceptual truth is only in other conceptual truths [Bolzano] |
| Full Idea: We can find the ground of a pure conceptual truth only in other conceptual truths. | |
| From: Bernard Bolzano (Theory of Science (Wissenschaftslehre, 4 vols) [1837], Pref) | |
| A reaction: Elsewhere he insists that these grounds must be in 'truths', and not just in the attributes of the concepts of involved. This conflicts with Kit Fine's view, that the concepts themselves are the source of conceptual truth and necessity. |
| 11214 | We learn 'not' along with affirmation, by learning to either affirm or deny a sentence [Rumfitt] |
| Full Idea: The standard view is that affirming not-A is more complex than affirming the atomic sentence A itself, with the latter determining its sense. But we could learn 'not' directly, by learning at once how to either affirm A or reject A. | |
| From: Ian Rumfitt ("Yes" and "No" [2000], IV) | |
| A reaction: [compressed] This seems fairly anti-Fregean in spirit, because it looks at the psychology of how we learn 'not' as a way of clarifying what we mean by it, rather than just looking at its logical behaviour (and thus giving it a secondary role). |
| 2860 | The most boring and dangerous of all errors is Plato's invention of pure spirit and goodness [Nietzsche] |
| Full Idea: The worst, most wearisomely protracted and most dangerous of all errors hitherto has been a dogmatist's error, namely Plato's invention of pure spirit and the good in itself. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], Pref) | |
| A reaction: A landmark observation about the history of philosophy. Imagine if all the Aristotle had survived, but all the Plato had been lost. |
| 1568 | Nietzsche felt that Plato's views downgraded the human body and its brevity of life [Nietzsche, by Roochnik] |
| Full Idea: Nietzsche believed that by elevating the importance of the mind, Plato downplayed the wonders of the body, and by searching for a timeless Truth he degraded the indisputable fact of human temporality. | |
| From: report of Friedrich Nietzsche (Beyond Good and Evil [1886], Pref) by David Roochnik - The Tragedy of Reason Prol. X | |
| A reaction: Both ideas are very important. The second is widely misunderstood. Nietzsche was not a denier of truth. He asked us to scrutinise the role and value we assign to truth. |
| 2883 | Noble people see themselves as the determiners of values [Nietzsche] |
| Full Idea: The noble type of man feels himself to be the determiner of values. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §260) | |
| A reaction: So do criminals |
| 23440 | Nietzsche's judgement of actions by psychology instead of outcome was poisonous [Foot on Nietzsche] |
| Full Idea: Nietzsche wants to judge actions not by what is done, but by the nature of the person who does them, and that is poisonous. We have to be horrified by what is done by Hitler and Stalin, without inquiring into their psychology. | |
| From: comment on Friedrich Nietzsche (Beyond Good and Evil [1886]) by Philippa Foot - Interview with Philippa Foot p.37 | |
| A reaction: She says morality should focus on social needs, not on spontaneity, energy and passion. Nietzsche was very much a product of romanticism. Some of Nietzsche's heroes are military conquerors, so I think she is right. |
| 2875 | That which is done out of love always takes place beyond good and evil [Nietzsche] |
| Full Idea: That which is done out of love always takes place beyond good and evil. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §153) | |
| A reaction: He is referring to the conventional morality of his contemporary society. Nietzsche clearly thought that actions motivated by love are intrinsically good. (Apart from murders by the jealous!). |
| 2868 | Nature is totally indifferent, so you should try to be different from it, not live by it [Nietzsche] |
| Full Idea: You Stoics want to "live according to nature"? Oh you noble Stoics, what fraudulent words! Nature is prodigal and indifferent beyond measure - how could you live by such indifference? Living is wanting to be other than nature. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §009) | |
| A reaction: I think this is simply indicative of the slide from optimism to pessimism about nature in the intervening centuries. Stoics thought nature rational. See 'King Lear' for the transition. |
| 2882 | Morality originally judged people, and actions only later on [Nietzsche] |
| Full Idea: Designation of moral values was everywhere first applied to human beings, and only later and derivatively to actions. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §260) | |
| A reaction: Nietzsche was a great expert on ethics in the ancient world, so you should trust him on this one. In ordinary life assessment of people is what counts. Actions are for law courts. |
| 2872 | In the earliest phase of human history only consequences mattered [Nietzsche] |
| Full Idea: Throughout the longest part of history ('prehistoric times') the value or non-value of an action was derived from its consequences. …but now men are unanimous that the value of an action is in the intention behind it. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §032) | |
| A reaction: This seems to be Kant's fault. No one thinks that a reckless or malicios action is innocent if no actual harm results. |
| 2885 | The noble soul has reverence for itself [Nietzsche] |
| Full Idea: The noble soul has reverence for itself. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §287) |
| 20134 | Moralities extravagantly address themselves to 'all', by falsely generalising [Nietzsche] |
| Full Idea: All moralities are baroque and unreasonable ...because they address themselves to 'all', because they generalise where one must not generalise. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §198) | |
| A reaction: 'Particularism' is a recent label, but one finds passing remarks from many earlier philosophers which support that approach to ethics. No one was ever more opposed to strict moral rules than Nietzsche. |
| 2881 | Virtue has been greatly harmed by the boringness of its advocates [Nietzsche] |
| Full Idea: May I be forgiven for the discovery that 'virtue' has been harmed by nothing more than it has been by the boringness of its advocates. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §228) |
| 20382 | The four virtues are courage, insight, sympathy, solitude [Nietzsche] |
| Full Idea: To remain master of one's four virtues: courage, insight, sympathy, solitude. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §284) | |
| A reaction: Compare this with 'Daybreak (Dawn)' 556. Solitude is the surprising addition, defended as the urge to 'cleanliness', when since humanity is 'unclean'. |
| 2879 | In ancient Rome pity was considered neither good nor bad [Nietzsche] |
| Full Idea: An act of pity was during the finest age of Rome considered neither good nor bad. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §201) |
| 2859 | The idea of the categorical imperative is just that we should all be very obedient [Nietzsche] |
| Full Idea: What does the claim that there exists in us a categorical imperative say of the man who asserts it? …that 'what is worthy of respect in me is that I know how to obey - and things ought to be no different with you'. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §187) |
| 2884 | The morality of slaves is the morality of utility [Nietzsche] |
| Full Idea: Slave morality is essentially the morality of utility. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §261) |
| 2880 | The greatest possibilities in man are still unexhausted [Nietzsche] |
| Full Idea: The greatest possibilities in man are still unexhausted. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §203) |
| 2876 | The thought of suicide is a great reassurance on bad nights [Nietzsche] |
| Full Idea: The thought of suicide is a powerful solace: by means of it one gets through many a bad night. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §157) |
| 7078 | The freedom of the subject means the collapse of moral certainty [Nietzsche, by Critchley] |
| Full Idea: In the 1880s Nietzsche diagnosed the concept of nihilism for a whole range of continental thinkers: the recognition of the subject's freedom goes hand in hand with the collapse of moral certainty in the world. | |
| From: report of Friedrich Nietzsche (Beyond Good and Evil [1886]) by Simon Critchley - Continental Philosophy - V. Short Intro Ch.5 | |
| A reaction: Avoiding this dilemma is just one of the many bonuses offered to those who abandon the idea of free will. The fact that one can decide to be wicked doesn't bring an end to morality. Philosophers should think more concretely about human life. |
| 6869 | Nietzsche thinks the human condition is to overcome and remake itself [Nietzsche, by Ansell Pearson] |
| Full Idea: Nietzsche thinks that the human condition is precisely to overcome itself; we continually remake ourselves. | |
| From: report of Friedrich Nietzsche (Beyond Good and Evil [1886]) by Keith Ansell Pearson - Interview with Baggini and Stangroom p.261 | |
| A reaction: This is why I think of Nietzsche as a straightforwardly existentialist philosopher. There is a crucial distinction between 'remaking' ourselves and 'realising all our possibilities'. The latter seems right. Which view did Nietzsche take? |
| 2874 | Man is the animal whose nature has not yet been fixed [Nietzsche] |
| Full Idea: Man is the animal whose nature has not yet been fixed. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §062) |
| 20137 | The great person engages wholly with life, and is happy to endlessly relive the life they created [Nietzsche] |
| Full Idea: There is an ideal ...of the most exuberant, most living and most world-affirming man, who has not only learned to get on and treat with all that was and is, but who wants to have it again as it was and is to all eternity. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §056) | |
| A reaction: This seems to be the main point of the idea of eternal recurrence. Could we inculcate this vision into the teenagers of our nation - that they should each try to design for themselves a life which they would be happy to endlessly repeat? Hm. |
| 20139 | Only aristocratic societies can elevate the human species [Nietzsche] |
| Full Idea: Every elevation of the type 'man' has thitherto been the work of an aristocratic society - and so it will always be: a society which believes in a long scale of orders of rank and differences of worth between man and man, and needs slavery in some sense. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §257) | |
| A reaction: The aim of 'elevating the type "man"' does not figure in works of political philosophy very much! I doubt whether one could base a political party on the idea, and win a general election. Could the people still be sold the idea of aristocracy? |
| 20373 | A healthy aristocracy has no qualms about using multitudes of men as instruments [Nietzsche] |
| Full Idea: A good and healthy aristocracy ...accepts with a good conscience the sacrifice of innumerable men who for its sake have to be suppressed and reduced to imperfect men, to slaves and instruments. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §258) | |
| A reaction: Something similar might be said of a democracy - that a slavelike workforce is needed to create the great universal goods we all want and need. Do the aristocrats want sacrifices for great art, or for wild parties and fox hunting? |
| 22394 | Democracy diminishes mankind, making them mediocre and lowering their value [Nietzsche] |
| Full Idea: To us the democratic movement is ...a form of decay, namely the diminution, of man, making him mediocre and lowering his value. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], §203), quoted by Philippa Foot - Nietzsche: the Revaluation of Values p.88 | |
| A reaction: It is not clear how a society of natural aristocrats followed by sheep would increase the value of mankind. Nor if the talented people are given total freedom, and the rest of us are servants. The value of humanity cannot reside in a few individuals. |
| 2867 | Christianity is Platonism for the people [Nietzsche] |
| Full Idea: Christianity is Platonism for the people. | |
| From: Friedrich Nietzsche (Beyond Good and Evil [1886], Pref) |
