David HumeUpon the whole, necessity is something, that exists in the mind, not in objects; nor is it possible for us ever to form the most distant idea of it, consider'd as a quality in bodies. Either we have no idea of necessity, or necessity is nothing but that determination of thought to pass from cause to effects and effects to causes, according to their experienc'd union.
David HumeIt is a certain rule that wit and passion are entirely incompatible. When the affections are moved, there is no place for the imagination.
David Hume
