3 ideas
22312 | Facts can be both positive and negative [Wittgenstein, by Potter] |
Full Idea: In 1913 Wittgenstein was explicit that there are both positive and negative facts. | |
From: report of Ludwig Wittgenstein (Notes on Logic [1913], B7) by Michael Potter - The Rise of Analytic Philosophy 1879-1930 47 'Mole' | |
A reaction: This is a prelude to the Tractatus, in which negative facts are denied in T1.11 (and in a 1919 letter), but then affirmed in T2.06. |
21799 | We just use the word 'faculty' when we don't know the psychological cause [Galen] |
Full Idea: So long as we are ignorant of the true essence of the cause which is operating, we call it a 'faculty'. | |
From: Galen (On the Natural Faculties [c.170], I.iv), quoted by Dominik Perler - Intro to The Faculties: a History 2 | |
A reaction: This is probably the view of most modern neuroscientists. I want to defend the idea that we need the concept of a faculty in philosophy, even if the psychologists and neuroscientists say it is too vague for their purposes. |
20992 | Right and wrong concerns what other people cannot reasonably reject [Scanlon] |
Full Idea: Thinking about right and wrong is, at the most basic level, thinking about what could be justified to others on grounds that they, if appropriately motivated, could not reasonably reject. | |
From: Thomas M. Scanlon (What We Owe to Each Other [1998], Intro) | |
A reaction: The tricky bit is that the acceptance by others must be 'reasonable', so we need a reasonably objective view of rationality. Don't picture your neighbours, picture the locals when you are on holiday in a very different culture. Other Nazis? |
