"My will does not produce the motive power to move my limbs. Rather, he who imparted motion to matter, and ordained its laws, shaped my will also; he thus joined together two utterly different things - the movement of matter and the decision of my will in such a way that whenever my will desires some action, the desired bodily movement will occur and vice versa, without there being any causation involved, or any influence of the one upon the other. It is just as if there were two clocks appropriately adjusted with reference to each other and the time of day in such a way that when one struck the hour the other immediately did likewise."
