My partial answer to Coleridge’s question in aphorism 40.

40.  The worth and value of Knowledge is in proportion to the worth and value of its object. What then is the best knowledge? The exactest knowledge of things, is to know them in their causes; it is  then an excellent thing, and worthy of their endeavours who are most desirous of knowledge, to know the best things in their highest causes; and the happiest way of attaining to this knowledge, is to possess those things, and to know them in experience.    [what things does Coleridge mean?
