18717 | Thought is an activity which we perform by the expression of it [Wittgenstein] |
Full Idea: Thought is an activity which we perform by the expression of it, and lasts as long as the expression. | |
From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B VIII) | |
A reaction: I take this to be an outmoded view of thought, which modern cognitive science has undermined, by showing how little of our thinking is actually conscious. |
4100 | The Twin Earth argument depends on reference being determined by content, which may be false. [Crane] |
Full Idea: The Twin Earth argument does not refute internalism, since it depends on the 'Content-Determines-Reference' principle, which internalists can reject. | |
From: Tim Crane (Elements of Mind [2001], 4.37) | |
A reaction: The idea is that content should be understood in a context (e.g. on a particular planet). Indexicals count against a totally narrow view of content (Twins thinking 'I am here'). |
4067 | Broad content entails the existence of the object of the thought [Crane] |
Full Idea: If a mental state is broad, then the existence of the mental state entails the existence of its object. | |
From: Tim Crane (Elements of Mind [2001], 1.7) | |
A reaction: Hence thinking of non-existent things like unicorns is problematic for externalists. However, externalists can think about numbers or Platonic ideals. |
4063 | In intensional contexts, truth depends on how extensions are conceived. [Crane] |
Full Idea: Intensional contexts are those where truth or falsehood depends on the way the extensions are conceived. | |
From: Tim Crane (Elements of Mind [2001], 1.4) | |
A reaction: An important distinction for anyone defending an internalist view of concepts or of knowledge |
