In some thoughts I grasp a subject, but also I will or fear or affirm or deny it [Descartes]
|
|
Full Idea:
Other thoughts are different from ideas, as when I will, or fear, or affirm, or deny, there is always some thing that I grasp as the subject of my thought, yet I embrace in my thought something more than the likeness of that thing.

From:
René Descartes (Meditations [1641], §3.37)
|
|
A reaction:
Note that the class of mental events we call 'propositional attitudes' had already been identified by Descartes. His categories of thinking in Med. Three might be one of his most important contributions, because that is what matters in the mind.

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.
