David

“What is the soul of man? A composition of various faculties, passions, sentiments, ideas; united, indeed, into one self or person, but still distinct from each other. When it reasons, the ideas which are the parts of its discourse arrange themselves in a certain form or order, which is not preserved entire for a moment, but immediately gives place to another arrangement. New opinions, new passions, new affections, new feelings arise which continually diversify the mental scene and produce in it the greatest variety and most rapid succession imaginable.”
― David Hume, Dialogues Concerning Natural Religion
