throughout history, the motive of philosophers and scientists has never been understood by merchants. we seek to understand for the sake of understanding. we seek knowledge for the sake of knowledge.
the merchant needs to put this in the context that he understands, and comes up with strange, if predictable conclusions. these conclusions always exist solely in the context of capital, of market exchange. how could they think otherwise? they is what they is.
but, the merchant can at least believe the philosopher when the philosopher explains: knowledge is a reward unto itself. the scientist would further clarify that the best way to attain knowledge is through observation.
you don't have to understand it to get it.
