7 ideas
13095 | Essence is primitive force, or a law of change [Leibniz] |
Full Idea: The essence of substances consists in the primitive force of action, or the law of the sequence of changes. | |
From: Gottfried Leibniz (Letters to Foucher [1675], 1676) | |
A reaction: [a 1676 note on Foucher's reply] It take these to be the two key distinctive Leibnizian contributions to the sort of metaphysic that is needed by modern science. Nature works with intrinsic essences, which are forces determining action. |
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. |
2854 | Prescriptivism says 'ought' without commitment to act is insincere, or weakly used [Hooker,B] |
Full Idea: Prescriptivism holds that if you think one 'ought' to do a certain kind of act, and yet you are not committed to doing that act in the relevant circumstances, then you either spoke insincerely, or are using the word 'ought' in a weak sense. | |
From: Brad W. Hooker (Prescriptivism [1995], p.640) | |
A reaction: So that's an 'ought', but not a 'genuine ought', then? (No True Scotsman move). Someone ought to rescue that drowning child, but I can't be bothered. |
2856 | Universal moral judgements imply the Golden Rule ('do as you would be done by') [Hooker,B] |
Full Idea: Prescriptivity is especially important if moral judgements are universalizable, for then we can employ golden rule-style reasoning ('do as you would be done by'). | |
From: Brad W. Hooker (Prescriptivism [1995], p.640) |
2117 | The connection in events enables us to successfully predict the future, so there must be a constant cause [Leibniz] |
Full Idea: There is a connection among our appearances that provides us the means to predict future appearances with success, and this connection must have a constant cause. | |
From: Gottfried Leibniz (Letters to Foucher [1675]) |
