| 2922 | All intelligent Romans were Epicureans [Nietzsche] |
| Full Idea: Every mind of any account in the Roman Empire was an Epicurean. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 58) |
| 23520 | Truth has had to be fought for, and normal life must be sacrificed to achieve it [Nietzsche] |
| Full Idea: Truth has had to be fought for every step of the way, almost everything else dear to our hearts, on which our love and our trust in life depend, has had to be sacrificed to it. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 50) | |
| A reaction: This, in one of his final works, seems to contradict every idea that Nietzsche is the high priest of relativism about truth. He (and Foucault) and interested in the social role of truth, but are not so daft as to reject its possibility. |
| 2914 | One must never ask whether truth is useful [Nietzsche] |
| Full Idea: One must never ask whether truth is useful. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], Fore) |
| 18996 | A statement S is 'partly true' if it has some wholly true parts [Yablo] |
| Full Idea: A statement S is 'partly true' insofar as it has wholly true parts: wholly true implications whose subject matter is included in that of S. | |
| From: Stephen Yablo (Aboutness [2014], 01.6) | |
| A reaction: He suggests that if we have rival theories, we agree that it is one or the other. And 'we may have pork for dinner, or human flesh' is partly true. |
| 19006 | An 'enthymeme' is an argument with an indispensable unstated assumption [Yablo] |
| Full Idea: An 'enthymeme' is a deductive argument with an unstated assumption that must be true for the premises to lead to the conclusion. | |
| From: Stephen Yablo (Aboutness [2014], 11.1) |
| 18999 | y is only a proper part of x if there is a z which 'makes up the difference' between them [Yablo] |
| Full Idea: The principle of Supplementation says that y is properly part of x, only if a z exists that 'makes up the difference' between them. [note: that is, z is disjoint from y and sums with y to form x] | |
| From: Stephen Yablo (Aboutness [2014], 03.2) |
| 19001 | 'Pegasus doesn't exist' is false without Pegasus, yet the absence of Pegasus is its truthmaker [Yablo] |
| Full Idea: 'Pegasus does not exist' has a paradoxical, self-undermining flavour. On the one hand, the empty name makes it untrue. But now, why is the name empty? Because Pegasus does not exist. 'Pegasus does not exist' is untrue because Pegasus does not exist. | |
| From: Stephen Yablo (Aboutness [2014], 05.7 n20) | |
| A reaction: Beautiful! This is Yablo's reward for continuing to ask 'why?' after everyone else has stopped in bewilderment at the tricky phenomenon. |
| 19002 | A nominalist can assert statements about mathematical objects, as being partly true [Yablo] |
| Full Idea: If I am a nominalist non-Platonist, I think it is false that 'there are primes over 10', but I want to be able to say it like everyone else. I argue that this because the statement has a part that I do believe, a part that remains interestingly true. | |
| From: Stephen Yablo (Aboutness [2014], 05.8) | |
| A reaction: This is obviously a key motivation for Yablo's book, as it reinforces his fictional view of abstract objects, but aims to capture the phenomena, by investigating what such sentences are 'about'. Admirable. |
| 18998 | Parthood lacks the restriction of kind which most relations have [Yablo] |
| Full Idea: Most relations obtain only between certain kinds of thing. To learn that x is a part of y, however, tells you nothing about x and y taken individually. | |
| From: Stephen Yablo (Aboutness [2014], 03.2) | |
| A reaction: Too sweeping. To be a part of crowd you have to be a person. To be part of the sea you have to be wet. It might depend on whether composition is unrestricted. |
| 19004 | Gettier says you don't know if you are confused about how it is true [Yablo] |
| Full Idea: We know from Gettier that if you are right to regard Q as true, but you are sufficiently confused about HOW it is true - about how things stand with respect to its subject matter - then you don't know that Q. | |
| From: Stephen Yablo (Aboutness [2014], 07.4) | |
| A reaction: I'm inclined to approach Gettier by focusing on the propositions being expressed, where his cases tend to focus on the literal wording of the sentences. What did the utterer mean by the sentences - not what did they appear to say. |
| 19007 | A theory need not be true to be good; it should just be true about its physical aspects [Yablo] |
| Full Idea: A physical theory need not be true to be good, Field has argued, and I agree. All we ask of it truth-wise is that its physical implications should be true, or, in my version, that it should be true about the physical. | |
| From: Stephen Yablo (Aboutness [2014], 12.5) | |
| A reaction: Yablo is, of course, writing a book here about the concept of 'about'. This seems persuasive. The internal terminology of the theory isn't committed to anything - it is only at its physical periphery (Quine) that the ontology matters. |
| 18993 | If sentences point to different evidence, they must have different subject-matter [Yablo] |
| Full Idea: 'All crows are black' cannot say quite the same as 'All non-black things are non-crows', for the two are confirmed by different evidence. Subject matter looks to be the distinguishing feature. One is about crows, the other not. | |
| From: Stephen Yablo (Aboutness [2014], Intro) | |
| A reaction: You might reply that they are confirmed by the same evidence (but only in its unobtainable totality). The point, I think, is that the sentences invite you to start your search in different places. |
| 19003 | Most people say nonblack nonravens do confirm 'all ravens are black', but only a tiny bit [Yablo] |
| Full Idea: The standard response to the raven paradox is to say that a nonblack nonraven does confirm that all ravens are black. But it confirms it just the teeniest little bit - not as much as a black raven does. | |
| From: Stephen Yablo (Aboutness [2014], 06.5) | |
| A reaction: It depends on the proportion between the relevant items. How do you confirm 'all the large animals in this zoo are mammals'? Check for size every animal which is obviously not a mammal? |
| 18992 | Sentence-meaning is the truth-conditions - plus factors responsible for them [Yablo] |
| Full Idea: A sentence's meaning is to do with its truth-value in various possible scenarios, AND the factors responsible for that truth-value. | |
| From: Stephen Yablo (Aboutness [2014], Intro) | |
| A reaction: The thesis of his book, which I welcome. I'm increasingly struck by the way in which much modern philosophy settles for a theory being complete, when actually further explanation is possible. Exhibit A is functional explanations. Why that function? |
| 18994 | The content of an assertion can be quite different from compositional content [Yablo] |
| Full Idea: Assertive content - what a sentence is heard as saying - can be at quite a distance from compositional content. | |
| From: Stephen Yablo (Aboutness [2014], Intro) | |
| A reaction: This is the obvious reason why semantics cannot be entirely compositional, since there is nearly always a contextual component which then has to be added. In the case of irony, the compositional content is entirely reversed. |
| 18997 | Truth-conditions as subject-matter has problems of relevance, short cut, and reversal [Yablo] |
| Full Idea: If the subject-matter of S is how it is true, we get three unfortunate results: S has truth-value in worlds where its subject-matter draws a blank; learning what S is about tells you its truth-value; negating S changes what it's about. | |
| From: Stephen Yablo (Aboutness [2014], 02.8) | |
| A reaction: Together these make fairly devastating objections to the truth-conditions (in possible worlds) theory of meaning. The first-objection concerns when S is false |
| 19005 | Not-A is too strong to just erase an improper assertion, because it actually reverses A [Yablo] |
| Full Idea: The idea that negation is, or can be, a cancellation device raises an interesting question. What does one do to wipe the slate clean after an improper assertion? Not-A is too strong; it reverses our stand on A rather than nullifying it. | |
| From: Stephen Yablo (Aboutness [2014], 09.8) | |
| A reaction: [He is discussing a remark of Strawson 1952] It seems that 'not' has two meanings or uses: a weak use of 'nullifying' an assertion, and a strong use of 'reversing' an assertion. One could do both: 'that's not right; in fact, it's just the opposite'. |
| 468 | Musical performance can reveal a range of virtues [Damon of Ath.] |
| Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice. | |
| From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where? |
| 2921 | Philosophy grasps the limits of human reason, and values are beyond it [Nietzsche] |
| Full Idea: All the supreme problems of value are beyond human reason. …To grasp the limits of human reason, only this is philosophy. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 55) | |
| A reaction: The single most powerful idea in the writings of Nietzsche. Reason and truth are values. Why do we value philosophy? There is no escaping Nietzsche's question. |
| 20138 | Christianity is at war with the higher type of man, and excommunicates his basic instincts [Nietzsche] |
| Full Idea: Christianity has waged a war to the death against the higher type of man, it has excommunicated all the fundamental instincts of this type. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 05) | |
| A reaction: It seems rather insulting to say that the finest and most dedicated altruism practised by the most admirable Christians is the expression of a 'lower' instinct. |
| 20375 | Virtues must be highly personal; if not, it is merely respect for a concept [Nietzsche] |
| Full Idea: A virtue has to be our invention, our most personal defence and necessity: in any other sense it is merely a danger. What does not condition our life harms it: a virtue merely from a feeling of respect for the concept 'virtue', as Kant desires it, is harm | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], §11) | |
| A reaction: Presumably he sees virtue as the cutting edge of stiffling conventional morality. I'm a bit nervous about embracing highly personal virtues, partly because they might isolate me from my community. I ain't no übermensch. |
| 2915 | Each person should devise his own virtues and categorical imperative [Nietzsche] |
| Full Idea: Each one of us should devise his own virtue, his own categorical imperative. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 11) |
| 2920 | A God who cures us of a head cold at the right moment is a total absurdity [Nietzsche] |
| Full Idea: A God who cures a headcold for us at the right moment is so absurd a God he would have to be abolished even if he existed. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 52) |
| 2917 | Christianity is a revolt of things crawling on the ground against elevated things [Nietzsche] |
| Full Idea: Christianity is a revolt of everything which crawls along the ground against everything which is elevated. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 43) |
| 2918 | The story in Genesis is the story of God's fear of science [Nietzsche] |
| Full Idea: Has the famous story which stands at the beginning of the Bible really been understood - the story of God's mortal terror of science? | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 48) |
| 2919 | 'Faith' means not wanting to know what is true [Nietzsche] |
| Full Idea: 'Faith' means not wanting to know what is true. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 52) |
| 2916 | The great lie of immortality destroys rationality and natural instinct [Nietzsche] |
| Full Idea: The great lie of personal immortality destroys all rationality, all naturalness of instinct. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 43) |
