William James, Essays in Radical Empiricism
“ Now it is obvious that we are tempted to affirm activity wherever we find anything going on. Taken in the broadest sense, any apprehension of something doing, is an experience of activity. Were our world describable only by the words ‘nothing happening,’ ‘nothing changing,’ ‘nothing doing,’ we should unquestionably call it an ‘inactive’ world. Bare activity then, as we may call it, means the bare fact of event or change. ‘Change taking place’ is a unique content of experience, one of those ‘conjunctive’ objects which radical empiricism seeks so earnestly to rehabilitate and preserve. ”
