Prevention by omission
The conterfactual theory solves the problems that prevention and omission cause for a wide range of theories of causation
Intuition of difference: we can recognise by reflection that cases of prevention and omission are not really cases of causation. But the mistake of treating them as if they were causation doesn’t matter. E.g. › See black holes
› Killing or letting die
› Neglect (lawful)
“Drink-driving causes accidentes”
› Perhaps alcohol prevents normal functioning
(prevention)…
› which in turn causes the accident (causation
by omission)
Single positive cause:
› One positive effect &
› Infinitely many negative effects
A prevented B ≡ A caused* ┐B if:
› (P1) A ocurred and B did not,
and there ocurred and x such
that
› (P2) there is a causal relation
between A and the process
due to x, such that either
A is a causal interaction with the causal process x, or
A causes y, a causal interaction with the causal process x, and
› (P3) if A had not occurred, x
would have caused B

La “intuición de la diferencia” solo indica que atribuimos ‘causalidad’ donde no la hay. Sin embargo, esta distinción solo es posible si disponemos de una noción primitiva de la causación. En el caso de Dowe, su noción de causación implica causalidad física (de cantidades conservadas). Así, porque su noción de causalidad solo puede ser eficiente (directa o por conexión), la “causalidad” negativa puede ser distinguida de ella y, por lo tanto, permitir la intuición de la diferencia.
Esto amerita una revisión más profunda del carácter universal de la teoría contrafáctica de Dowe.
