Tho' some of these fine Thoughts are very nearly allied to the Noble, yet one may easily perceive, that there is not so much Dignity, tho' there may be as much Beauty in the One as in the Other. Thus also, as to delicate and agreeable Thoughts, they are as nearly related; but a Thing may be agreeable which is not delicate, tho' it cannot be delicate, but it must be agreeable: An agreeable Thought expresses it self entirely; a delicate One leaves something to the Readers Imagination which is very flattering.
