For, when we perceive certain ideas of Sense constantly followed by other ideas and WE KNOW THIS IS NOT OF OUR OWN DOING, we forthwith attribute power and agency to the ideas themselves, and make one the cause of another, than which nothing can be more absurd and unintelligible. cache/4723.txt txt/4723.txt
