Only the actual exists, so possibilities always reduce to actuality after full analysis [Russell]
|
|
Full Idea:
Possibility always marks insufficient analysis: when analysis is completed, only the actual can be relevant, for the simple reason that there is only the actual, and that the mere possibility is nothing.
|
|
From:
Bertrand Russell (Papers of 1913 [1913], VII.26), quoted by Michael Potter - The Rise of Analytic Philosophy 1879-1930 42 'Logic'
|
|
A reaction:
Quine agreed with Russell on this. You won't get far in life if you deny possibilities. The answer is to recognise that the actual is dynamic, and not passive.

We can't be objective about experience [Nagel]
|
|
Full Idea:
If the subjective character of experience is fully comprehensible only from one point of view, then any shift to greater objectivity does not take us nearer to the real nature of the phenomenon: it takes us further away from it.
|
|
From:
Thomas Nagel (What is it like to be a bat? [1974], p.174)
|
|
A reaction:
We can, however, talk to one another about our subjectivity, and compare notes, and such 'inter-subjectivity' may be one approach to objectivity. We must concede Nagel's point, but we also miss something about a stone if we must remain outside of it.

Physicalism should explain how subjective experience is possible, but not 'what it is like' [Kirk,R on Nagel]
|
|
Full Idea:
A physicalist account of conscious experience must explain how it is possible for a physical system to be a conscious subject, but not 'what it is like' for some organism.
|
|
From:
comment on Thomas Nagel (What is it like to be a bat? [1974]) by Robert Kirk - Mind and Body §4.2
|
|
A reaction:
You can't entirely evade Nagel's challenge. We are trying to discover the 'neural correlate of consciousness', which will explain why we are conscious, but we also want to know why we experience green for one wavelength, and red for another.

Many mental phenomena are totally unexplained by folk psychology [Churchland,PM]
|
|
Full Idea:
Folk psychology fails utterly to explain a considerable variety of central psychological phenomena: mental illness, sleep, creativity, memory, intelligence differences, and many forms of learning, to cite just a few.
|
|
From:
Paul M. Churchland (Folk Psychology [1996], III)
|
|
A reaction:
If folk psychology is a theory, it will have been developed to predict behaviour, rather than as a full-blown psychological map. The odd thing is that some people seem to be very bad at folk psychology.

Folk psychology never makes any progress, and is marginalised by modern science [Churchland,PM]
|
|
Full Idea:
Folk psychology has not progressed significantly in the last 2500 years; if anything, it has been steadily in retreat during this period; it does not integrate with modern science, and its emerging wallflower status bodes ill for its future.
|
|
From:
Paul M. Churchland (Folk Psychology [1996], III)
|
|
A reaction:
[compressed] However, while shares in alchemy and astrology have totally collapsed, folk psychology shows not the slightest sign of going away, and it is unclear how it ever could. See Idea 3177.
