Trumping preemption y causación por obturación

Abstract

Counterfactual causation theories have been faced many difficulties. One of them is the obstacle of causal overdetermination in its four different types: symetrical overdetermination, early preemption, late preemption and trumping preemption. This paper deal with the problem of trumping preemption and shows that such a causal overdetermination type is not possible to be found in our natural world. Every example rised to justify the existence of this kind of preemption either envolve human actions or take for granted a world with different laws than seems to be valid in the actual world. Additionally the alleged type could be much better understood as a new type of causation we can call it«block in causation» that give a good account of the examples of nature leavingaside the really trumping cases out of this (natural) world.
