A causal deviance is an abnormal, though causal, relation between events or states of the world. It mainly arises when we introduce intentional action and perception into the theory of causation. Let us revert to the much-maligned owner of the sinking Titanic. He intended to do one thing and another happened. Granted, if he intended to do something and his intention was the cause of his doing so - then we could have said that he intentionally committed an act. But what if he intended to do one thing and out came another? And what if he intended to do something, mistakenly did something else and, still, accidentally, achieved what he set out to do? The popular example is if someone intends to do something and gets so nervous that it happens even without an act being committed (intends to refuse an invitation by his boss, gets so nervous that he falls asleep and misses the party). Are these actions and intentions in their classical senses? There is room for doubt. Davidson narrows down the demands. To him, "thinking causes" (causally efficient propositional attitudes) are nothing but causal relations between events with the right application of mental predicates which ascribe propositional attitudes supervening the right application of physical predicates. This approach omits intention altogether, not to mention the ascription of desire and belief. But shouldn't have the hapless owner availed his precious place to women and children? Should not he have obeyed the captain's orders (=the marine law)? Should we succumb to laws that put our lives at risk (fight in a war, sink with a ship)? The reason that women and children are preferred over men is that they represent the future. They are either capable of bringing life to the world (women) - or of living longer (children). Societal etiquette reflects the arithmetic of the species, in this (and in many another) case. But if this were entirely and exclusively so, then young girls and female infants would have been preferred over all the other groups of passengers. Old women would have been left with the men, to die. That the actual (and declared) selection processes differed from our theoretical exercise says a lot about the vigorousness and applicability of our theories - and a lot about the real world out there. The owner's behaviour may have been deplorable - but it, definitely, was natural. He put his interests (his survival) above the concerns of his society and his species. Most of us would have done the same under the same circumstances.
