All these things are parts of an integral whole; they all go to the formation of an Art. Art is in itself only a part of the mechanism of truth. It is from the inner spirit that the outward seeming must derive. Rules and laws are but aids, restraints, methods of achievement; but it is after all to nature that the artist must look. In the words of Pope:
“These laws of old discover’d, not deviz’d,
Are nature still but nature methodiz’d.”
Irving put the idea thus:
“... merely to imitate is not to apply a similar method ... the greatest of all the lessons that Art can teach is this: that truth is supreme and eternal. No phase of art can achieve much on a false basis. Sincerity, which is the very touchstone of Art, is instinctively recognised by all.”
