A Treatise of Human Nature HTML version

body upon another in any situation, I need only put them in that situation, and observe
what results from it. But should I endeavour to clear up after the same manner any doubt
in moral philosophy, by placing myself in the same case with that which I consider, it is
evident this reflection and premeditation would so disturb the operation of my natural
principles, as must render it impossible to form any just conclusion from the
phenomenon. We must therefore glean up our experiments in this science from a cautious
observation of human life, and take them as they appear in the common course of the
world, by men's behaviour in company, in affairs, and in their pleasures. Where
experiments of this kind are judiciously collected and compared, we may hope to
establish on them a science which will not be inferior in certainty, and will be much
superior in utility to any other of human comprehension.
