“ The volume, originating in a defence of Turner's later manner, had grown into a treatise on the principles of art, declaring that art means something more than pleasing arrangement of lines and colours ; that it can, and therefore ought to, convey ideas as being a kind of language; that the best painter is he who conveys the most and highest ideas of truth, of beauty, and of imagination ; and then, by way of example, that Turner's work was full of interesting truths, while the Dutch and French-Italian landscapists were very limited in their view of the varied facts of nature. ”
