Philosophers should be more inductive, and test results by their conclusions, not their self-evidence [Russell]
|
|
Full Idea:
The progress of philosophy seems to demand that, like science, it should learn to practise induction, to test its premisses by the conclusions to which they lead, and not merely by their apparent self-evidence.

A reaction:
[from Twitter] Love this. It is 'one person's modus ponens is another person's modus tollens'. I think all philosophical conclusions, without exception, should be reached by evaluating the final result fully, and not just following a line of argument.

We can't sharply distinguish variables, domains and values, if symbols frighten us [Russell]
|
|
Full Idea:
Whoever is afraid of symbols can hardly hope to acquire exact ideas where it is necessary to distinguish 1) the variable in itself as opposed to its value, 2) any value of the variable, 3) all values, 4) some value.

From:
Bertrand Russell (Review: Meinong 'Untersuchungen zur..' [1905], p.84)
|
|
A reaction:
Not the best example, perhaps, of the need for precision, but a nice illustration of the new attitude Russell brought into philosophy.

I prefer to deny round squares, and deal with the difficulties by the theory of denoting [Russell]
|
|
Full Idea:
I should prefer to say that there is no such object as 'the round square'. The difficulties of excluding such objects can, I think, be avoided by the theory of denoting.
|
|
From:
Bertrand Russell (Review: Meinong 'Untersuchungen zur..' [1905], p.81)
|
|
A reaction:
The 'theory of denoting' is his brand new theory of definite descriptions, which makes implicit claims of existence explicit, so that they can be judged. Why can't we just say that a round square can be an intentional object, but not a real object?

Libet found conscious choice 0.2 secs before movement, well after unconscious 'readiness potential' [Libet, by Lowe]
|
|
Full Idea:
Libet found that a subject's conscious choice to move was about a fifth of a second before movement, and thus later than the onset of the brain's so-called 'readiness potential', which seems to imply that unconscious processes initiates action.
|
|
From:
report of Benjamin Libet (Unconscious Cerebral Initiative [1985]) by E.J. Lowe - Introduction to the Philosophy of Mind Ch.9
|
|
A reaction:
Of great interest to philosophers! It seems to make conscious choices epiphenomenal. The key move, I think, is to give up the idea of consciousness as being all-or-nothing. My actions are still initiated by 'me', but 'me' shades off into unconsciousness.
