| 9777 | Kant was the first philosopher [Zizek] |
| Full Idea: From today's perspective it is in a way clear that Kant was the first philosopher. Pre-Kantian philosophy cannot think in his transcendental aspect. | |
| From: Slavoj Zizek (Conversations, with Glyn Daly [2004], §1) | |
| A reaction: It is probably equally plausible to say that Kant was the last philosopher. More thought-provoking than true. |
| 9778 | There is no dialogue in philosophy [Zizek] |
| Full Idea: I think I truly became a philosopher when I realised that there is no dialogue in philosophy. Plato's dialogues are clearly fakes, with one guy talking most of the time. ...Philosophy as an interdisciplinary project is the ultimate nightmare. | |
| From: Slavoj Zizek (Conversations, with Glyn Daly [2004], §1) | |
| A reaction: This goes against all my prejudices in favour of teamwork and mutual criticism (e.g. Idea 1576), but I was a bit shaken by it, and have begun to wonder whether I must just face up to the solitary nature of the enterprise. |
| 9779 | Philosophy is transcendental questioning (not supporting science or constructing ontology) [Zizek] |
| Full Idea: Philosophy can no longer play its traditional roles, giving foundations to science, or constructing general ontology. It should simply fulfil its task of transcendental questioning. | |
| From: Slavoj Zizek (Conversations, with Glyn Daly [2004], §2) | |
| A reaction: I remain unsure what is being recommended, unless it is for philosophy to start asking questions just at the point where everyone else gives up. |
| 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. |
| 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? |
| 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. |
| 9780 | Consciousness is a malfunction of evolution [Zizek] |
| Full Idea: Consciousness is a kind of mistake, a malfunction of evolution, and out of this mistake a miracle occurred. | |
| From: Slavoj Zizek (Conversations, with Glyn Daly [2004], §2) | |
| A reaction: Rather hard to prove, but actually quite an uplifting thought. If consciousness only evolved so that we could navigate and defend ourselves, our 'higher' activities seem irrelevant. But Zizek's view means we can make them central. Nice. |
| 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? |
| 9781 | Tolerance and love are strategies to avoid encountering our neighbours [Zizek] |
| Full Idea: All this preaching about tolerance, love for one's neighbour and so on, are ultimately strategies to avoid encountering the neighbour. | |
| From: Slavoj Zizek (Conversations, with Glyn Daly [2004], §2) | |
| A reaction: I have begun to wonder whether some such motivation underlies the modern obsession with raising huge sums for charity. |
