The study gives a temporal analysis of actions. Thereby it tries to show that there is a crucial connection between action theory and time theory. It is based on the idea that the main difference in time theory between A- and B-series of time is related to the main difference in action theory between causal and teleological concepts of action. Teleological concepts need A-time-series because goals are in the future related to the view of the agent in acting – and not just later as the time he is in now. They cannot be replaced by causal explications without cutting the idea of goal-directed action in the same way as in time theory the concept of future, as a part of the A-series, cannot be reduced to the B-series of time.
