Single Idea 5179
[filed under theme 1. Philosophy / G. Scientific Philosophy / 3. Scientism
]
Full Idea
If there are any questions which science leaves it to philosophy to answer, a straightforward process of elimination must lead to their discovery.
Gist of Idea
Philosophy deals with the questions that scientists do not wish to handle
Source
A.J. Ayer (Language,Truth and Logic [1936], Ch.1)
Book Ref
Ayer,A.J.: 'Language, Truth and Logic' [Penguin 1974], p.45
A Reaction
This is characteristic of the feeble-mindedness that British philosophy slipped into in the age of Wittgenstein, and for a while thereafter. Personally I regard scientists as servants, who are sent off on exploratory errands, and must report back.

|
Temporal gaps in the consciousness of a spirit could not be bridged by memories

Why shouldn't we say brain depends on mind? Better explanation!
[Ayer]
|
5328
|
Originally I combined a mentalistic view of introspection with a behaviouristic view of other minds
[Ayer]
|
5330
