15585 | Later Heidegger sees philosophy as more like poetry than like science [Heidegger, by Polt] |
Full Idea: In his later work Heidegger came to view philosophy as closer to poetry than to science. | |
From: report of Martin Heidegger (The Origin of the Work of Art [1935], p.178) by Richard Polt - Heidegger: an introduction 5 'Signs' |
4921 | Quantum states in microtubules could bind brain activity to produce consciousness [Penrose] |
Full Idea: I propose that microtubules in nerve cells could give rise to a stable quantum state that would bind the activity of brain cells throughout the cerebrum and in doing so give rise to consciousness. | |
From: Roger Penrose (Could a computer ever understand? [1998], p.329) | |
A reaction: This seems to offer a physical theory to account for the 'unity' of the mind (which so impressed Descartes), but I don't quite see why being aware of things would ensue from some 'quantum binding'. I daresay 'quantum binding' occurs in the Sun. |
6387 | A minimum requirement for a theory of meaning is that it include an account of truth [Davidson] |
Full Idea: Whatever else it embraces, a theory of meaning must include an account of truth - a statement of the conditions under which an arbitrary sentence of the language is true. | |
From: Donald Davidson (Reality without Reference [1977], p.132) | |
A reaction: It is a moot point whether we can define meaning if we assume truth, or if we can define truth by assuming meaning. Tarski seems to presuppose meaning when he defines truth (Idea 2345). I like Davidson's taking of truth as basic. |
6391 | A theory of truth tells us how communication by language is possible [Davidson] |
Full Idea: A theory of truth lets us answer the underlying question how communication by language is possible. | |
From: Donald Davidson (Reality without Reference [1977], p.137) | |
A reaction: If, instead, you explain communication by understood intentions (á la Grice), you have to say more about what sort of intentions are meant. If you use reference, you still have more to say about the meaning of sentences. Davidson looks good. |
6388 | Is reference the key place where language and the world meet? [Davidson] |
Full Idea: The essential question is whether reference is the, or at least one, place where there is direct contact between linguistic theory and events, actions, or objects described in nonlinguistic terms. | |
From: Donald Davidson (Reality without Reference [1977], p.134) | |
A reaction: How do you 'describe objects in nonlinguistic terms'? The causal theory of reference (e.g. Idea 4957) is designed to plug language straight into the world via reference. It simplifies things nicely, but I don't quite believe it. |
6390 | With a holistic approach, we can give up reference in empirical theories of language [Davidson] |
Full Idea: I defend a version of the holistic approach, and urge that we must give up the concept of reference as basic to an empirical theory of language. | |
From: Donald Davidson (Reality without Reference [1977], p.136) | |
A reaction: He proposes to connect language to the world via the concept of truth, rather than of reference. It is a brilliant idea, and is the key issue in philosophy of language. I go back to animals, which seem to care about situations rather than things. |
6389 | To explain the reference of a name, you must explain its sentence-role, so reference can't be defined nonlinguistically [Davidson] |
Full Idea: It is inconceivable that one should be able to explain the relationship between 'Kilimanjiro' and Kilimanjiro without first explaining the role of the word in sentences; hence there is no chance of explaining reference directly in nonlinguistic terms. | |
From: Donald Davidson (Reality without Reference [1977], p.135) | |
A reaction: I point at the mountain, and a local says 'Kilimanjiro'? There is a 'gavagai'-type problem with that. The prior question might be 'what is it about this word that enables it to have a role in sentences?' Unlike whimpering or belching. |
