8868 | Objective truth arises from interpersonal communication [Davidson] |
Full Idea: The source of the concept of objective truth is interpersonal communication. | |
From: Donald Davidson (Three Varieties of Knowledge [1991], p.209) | |
A reaction: This is a distinctively Davidsonian idea, arising out of Wittgenstein's Private Language Argument. We could go a step further, and just say that 'objectivity is a social concept'. Davidson more or less pleads guilty to pragmatism in this essay. |
18491 | The idea of 'making' can be mere conceptual explanation (like 'because') [Künne] |
Full Idea: If we say 'being a child of our parent's sibling makes him your first cousin', that can be paraphrased using 'because', and this is the 'because' of conceptual explanation: the second part elucidates the sense of the first part. | |
From: Wolfgang Künne (Conceptions of Truth [2003], 3.5.2) | |
A reaction: Fans of truth-making are certainly made uncomfortable by talk of 'what makes this a good painting' or 'this made my day'. They need a bit more sharpness to the concept of 'making' a truth. |
12066 | Aristotelian and Kripkean essentialism are very different theories [Witt] |
Full Idea: The differences between Aristotelian essentialism and Kripke's essentialism are so fundamental and pervasive that it is a serious distortion of both views to think of essentialism as a single theory. | |
From: Charlotte Witt (Substance and Essence in Aristotle [1989], Intro) | |
A reaction: This seems to me to be very important, because there is a glib assumption that when essentialism is needed for modal logic, that we must immediately have embraced what Aristotle was saying. Aristotle was better than Kripke. |
12067 | An Aristotelian essence is a nonlinguistic correlate of the definition [Witt] |
Full Idea: An Aristotelian essence is a nonlinguistic correlate of the definition of the entity in question. | |
From: Charlotte Witt (Substance and Essence in Aristotle [1989], Intro) | |
A reaction: This is a simple and necessity corrective to the simplistic idea that Aristotle thought that essences just were definitions. Aristotle believes in real essences, not linguistic essences. |
12082 | If unity is a matter of degree, then essence may also be a matter of degree [Witt] |
Full Idea: By holding that the most unified beings have essences in an unqualified sense, while allowing that other beings have them in a qualified sense - we can think of unity as a matter of degree. | |
From: Charlotte Witt (Substance and Essence in Aristotle [1989], 4.3) | |
A reaction: This is Witt's somewhat unorthodox view of how we should read Aristotle. I am sympathetic, if essences are really explanatory. That means they are unstable, and would indeed be likely to come in degrees. |
12089 | Essences mainly explain the existence of unified substance [Witt] |
Full Idea: The central function of essence is to explain the actual existence of a unified substance. | |
From: Charlotte Witt (Substance and Essence in Aristotle [1989], 5 n1) | |
A reaction: She is offering an interpretation of Aristotle. Since existence is an active and not a passive matter, the identity of the entity will include its dispositions etc., I presume. |
12102 | Essential properties of origin are too radically individual for an Aristotelian essence [Witt] |
Full Idea: The radical individuality of essential properties of origin makes them unsuitable for inclusion in an Aristotelian essence. | |
From: Charlotte Witt (Substance and Essence in Aristotle [1989], 6.2) | |
A reaction: Nevertheless, Aristotle believes in individual essences, though these seem to be fixed by definitions, which are composed of combinations of universals. The uniqueness is of the whole definition, not of its parts. |
8867 | A belief requires understanding the distinctions of true-and-false, and appearance-and-reality [Davidson] |
Full Idea: Having a belief demands in addition appreciating the contrast between true belief and false, between appearance and reality, mere seeming and being. | |
From: Donald Davidson (Three Varieties of Knowledge [1991], p.209) | |
A reaction: This sets the bar very high for belief (never mind knowledge), and seems to imply that animals don't have beliefs. How should we describe their cognitive states then? I would say these criteria only apply to actual knowledge. |
10347 | Objectivity is intersubjectivity [Davidson] |
Full Idea: An entity is objective in so far as it is intersubjective. | |
From: Donald Davidson (Three Varieties of Knowledge [1991]), quoted by Martin Kusch - Knowledge by Agreement Ch.10 | |
A reaction: This thought baffled me until I saw it in the context of socialised epistemology. Effectively objectivity is subsumed under justification, which in turn is seen in a social context, not private to individuals. |
8866 | If we know other minds through behaviour, but not our own, we should assume they aren't like me [Davidson] |
Full Idea: If the mental states of others are known only through their behavioral and other outward manifestations, while this is not true of our own mental states, why should we think our own mental states are anything like those of others? | |
From: Donald Davidson (Three Varieties of Knowledge [1991], p.207) | |
A reaction: His point is that if you seriously doubt other minds, you should follow through on the implications. But that is to treat it as a theory about other minds, rather an a sceptical worry. Descartes didn't walk into walls while writing Meditation 1. |
10346 | Knowing other minds rests on knowing both one's own mind and the external world [Davidson, by Dummett] |
Full Idea: Davidson argues that knowledge of other minds presupposes knowledge of one's own mind, and that there is no knowledge of other minds without knowledge of the external world. | |
From: report of Donald Davidson (Three Varieties of Knowledge [1991]) by Michael Dummett - Common Sense and Physics Ch.10 | |
A reaction: Davidson't argument is actually hard to swallow because it is so long and complex. Compressing the point makes it begin to sound like a variant of the argument from analogy. |
8870 | Content of thought is established through communication, so knowledge needs other minds [Davidson] |
Full Idea: Until a baseline has been established by communication with someone else, there is no point is saying one's own thoughts have a propositional content. Hence knowledge of another mind is essential all thought and all knowledge. | |
From: Donald Davidson (Three Varieties of Knowledge [1991], p.213) | |
A reaction: This really is building a skyscraper on the slightly shaky claims of the Private Language Argument (e.g. Idea 4158). Animals are so important in discussions of this kind. Is an albatross more or less devoid of thought and belief? |
8869 | The principle of charity attributes largely consistent logic and largely true beliefs to speakers [Davidson] |
Full Idea: Concerning charity, the Principle of Coherence seeks logical consistency in the thought of the speaker, and the Principle of Correspondence seeks a similar response to features of the world to that of an interpreter. The speaker has logic and true belief. | |
From: Donald Davidson (Three Varieties of Knowledge [1991], p.211) | |
A reaction: Davidson adds a Kantian commitment to pure and universal reason to the very sceptical framework created by Quine. I agree with Davidson, but it seems more like faith than like an argument or an empirical observation. |
12085 | Reality is directional [Witt] |
Full Idea: Reality is directional. | |
From: Charlotte Witt (Substance and Essence in Aristotle [1989], 4.5) | |
A reaction: [Plucked from context! She attributes the view to Aristotle] This slogan beautifully summarises the 'scientific essentialist' view of reality, based not on so-called 'laws', but on the active powers of the stuffs of reality. |
