as forms of summoning of means within one's power and are different from merely intending to do something later. Non-causalists, on the other hand, deny that intentions or similar states cause actions. Davidson's account The most well-known account of action, sometimes simply referred to as the standard account, is due to Davidson, who holds that actions are bodily movements that are caused by intentions. Davidson explains the intentions themselves in terms of beliefs and desires. For example, the action of flipping a light switch rests, on the one hand, on the agent's belief that this bodily movement would turn on the light and, on the other hand, on the desire to have light. Because of its reliance on psychological states and causal relations, this position is considered to be a Humean theory of action. According to Davidson, it is not just the bodily behavior that counts as the action but also the consequences that follow from it. So the movement of the finger flipping the switch is part of the action as well as the electrons moving through the wire and the light bulb turning on. Some consequences are included in the action even though the agent did not intend them to happen. It is sufficient that what the agent does "can be described under an aspect that makes it intentional". So, for example, if flipping the light switch alerts the burglar then alerting the burglar is part of the agent's actions. In an example from Anscombe's manuscript Intention, pumping water can also be an instance of poisoning the inhabitants. One difficulty with theories of action that try to characterize actions in terms of causal relations between mental states and bodily movements, so-called causalist theories, is what has been referred to as wayward causal chains. A causal chain is wayward if the intention caused its goal to realize but in a very unusual way that was not intended, e.g. because the skills of the agent are not exercised in the way planned. For example, a rock climber forms the intention to kill the climber below him by letting go of the rope. A wayward causal chain would be that, instead of opening the holding hand intentionally, the intention makes the first climber so nervous that the rope slips through his hand and thus leads to the other climber's death. Davidson addresses this issue by excluding cases of wayward causation from
