6 ideas

1. Philosophy / F. Analytic Philosophy / 2. Analysis by Division

13099	Analysing right down to primitive concepts seems beyond our powers [Leibniz]
	Full Idea: An analysis of concepts such that we can reach primitive concepts...does not seem to be within human power.
	From: Gottfried Leibniz (Introduction to a Secret Encyclopaedia [1679], C513-14), quoted by Cover,J/O'Leary-Hawthorne,J - Substance and Individuation in Leibniz
	A reaction: Leibniz is nevertheless fully committed, I think, to the existence of such primitives, and is in the grip of the rationalist dream that thoughts can become completely clear, and completely well-founded.

3. Truth / A. Truth Problems / 8. Subjective Truth

5022	We hold a proposition true if we are ready to follow it, and can't see any objections [Leibniz]
	Full Idea: A proposition is held to be true by us when our mind is ready to follow it and no reason for doubting it can be found.
	From: Gottfried Leibniz (Introduction to a Secret Encyclopaedia [1679], p.7)
	A reaction: This follows on from Descartes' view, but it now sounds more like psychology than metaphysics. Clearly a false proposition could fit this desciption. Personally I follow propositions to which I can see no objection, without actually holding them true.

18. Thought / A. Modes of Thought / 4. Folk Psychology

7518	If folk psychology gives a network of causal laws, that fits neatly with functionalism [Churchland,PM]
	Full Idea: The portrait of folk psychology as a network of causal laws dovetailed neatly with the emerging philosophy of mind called functionalism.
	From: Paul M. Churchland (Folk Psychology [1996], II)
	A reaction: And from the lower levels functionalism is supported by the notion that the brain is modular. Note the word 'laws'; this implies an underlying precision in folk psychology, which is then easily attacked. Maybe the network is too complex for simple laws.

7519	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.

7520	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.

26. Natural Theory / A. Speculations on Nature / 7. Later Matter Theories / b. Corpuscles

16707	Cold and hot are the swiftness and slowness of corpuscular motion [Beeckman]
	Full Idea: There is no doubt that the nature of cold and hot are taken from the swiftness and slowness of the motion of corpuscules.
	From: Isaac Beeckman (Journals [1617], I:132), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 19.6
	A reaction: This is so right it takes your breath away. For 'corpuscles' we should normally read 'molecules'. Atomism is a further refinement. This is the rejection of the orthodox view of separate qualities.
