21900 | Deleuze relies on Spinoza (immanence), Bergson (duration), and difference (Nietzsche) [May] |
Full Idea: The three tripods on which the philosophy of Deleuze stands are immanence (Spinoza), duration (Bergson), and the affirmation of difference (Nietzsche). | |
From: Todd May (Gilles Deleuze [2006], 2.12) | |
A reaction: [Just to begin sketching how continental philosophy sees its tradition]. |
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. |
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. |
23218 | The brain has no responsibility for sensations, which occur in the heart [Aristotle] |
Full Idea: And of course, the brain is not responsible for any of the sensations at all. The correct view is that the seat and source of sensation is the region of the heart. | |
From: Aristotle (The Parts of Animals [c.345 BCE]), quoted by Matthew Cobb - The Idea of the Brain 1 | |
A reaction: [Need a reference] Hippocrates's assertion a century earlier made no impression on the great man. I wish he had been a little more circumspect with his own view. |
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. |
21898 | For existentialists the present is empty without the pull of the future and weight of the past [May] |
Full Idea: For the existential view of lived time, the present would be empty if it were not for the pull of the future and the weight of the past that give it its character. | |
From: Todd May (Gilles Deleuze [2006], 2.05) | |
A reaction: Bergson seems to be important in developing this idea, though I suspect that Kierkegaard is a source. |
21905 | Liberal theory starts from the governed, not from the governor [May] |
Full Idea: For liberal theory, it is the individual to be governed, not the governor, who is the starting point. | |
From: Todd May (Gilles Deleuze [2006], 4.02) | |
A reaction: I'm inclined to see this as the single-handed achievement of Thomas Hobbes, who starts from the need of citizens to secure their contracts. Plato's society starts from entrepreneurs, but their need for a ruler seems a priori. |
