What are Causes?
2David Hume
We may define a cause to be an object, followed
by another, and where all the objects similar to
the first are followed by objects similar to the
second.
Or in other words where, if the first object had
not been, the second never had existed.
3Humes first formulation
c causes e iff for some (natural?) properties
F, G all Fs are followed by Gs
4causation as regularity
5Mithradates VI of Pontus took arsenic but did not
die
6greying of hair
lengthening of eyesight
problem of the common cause
7Humes second formulation
c causes e iff had c not occurred e would not
have occurred
8causation as counterfactual dependence
9Is counterfactual dependence necessary for
causation?
Had A not shot, V would not have died
?
Had A not shot, B would have shot, and V would
have died
late pre-emption
10causal chains
causal chain A ? I and I ? V
V counterfactually depends on I and I
counterfactually depends on A
11causal chains
A
V does not counterfactually depend on I
(or I does not counterfactually depend on A)
early pre-emption
12causation as mechanism
13causation is a process that can transmit a mark
14causation by absence?
the wilting of the plants was caused by the lack
of water
counterfactual dependence but no
mark-transmitting process
