ABSTRACT. I show that the assumption of a power or force which connects cause and effect is an essential characteristic of our concept of cause. I present the criteria of the Agency Theory of Causality which I appreciate as correct. I show why this theory assumes the idea of force connecting cause and effect, and I propose that the idea originates in the experience of "being compelled or induced" to undertake an action. I analyse an argument in favour of the opinion of Backwards Causation presented by Michael Dummett. I also investigate the apparent implausibility of backwards causation. I believe that the reason it is regarded as implausible has to do with the experience that localize force as the factor that links cause and effect.
