A Dispositionalist Analysis of Causation
|
Dispositional
analyses of causations are unpopular in these days. Some philosophers
think that there are no dispositional properties at all only
dispositional terms. Some claim that even if there are dispositional
properties they are ‘causally inert’. And some claim that even if
dispositional terms refer to causally relevant properties explaining
causation by saying that it is an exertion of some causal power is just
trivial. All these charges usually presuppose that the relation between
causation and causal dispositions can only be explained by the fact
that causal dispositions entail the corresponding conditional. Although
I believe that they do (which is a contentious issue) I offer an
alternative account of disposition ascriptions using probabilities
rather than conditionals. Then I show [1] how my account can meet the
standard problems about disposition ascriptions; [2] the (non-trivial)
connection between disposition ascription and causation; [3] the sense
in which dispositions can imply the corresponding conditionals; [4] how
a dispositionalist account of causation can answer various puzzles
about preemption.

Megmaradási
tételek a relativisztikus dinamikában
(Conservation postulates in relativistic
dynamics) |
Az előadásban
megadjuk a relativisztikus dinamika egy elsőrendű logikai
axiómarendszerét, amely megfigyelés orientált és geometriai szemléletű.
Majd megvizsgáljuk az axiómarendszer és a megmaradási tételek (tömeg,
impulzus, négyesimpulzus megmaradás) logikai kapcsolatát. Az előadás
lényegében véve az [1] cikk eredményeinek ismertetése.
