I wish you would recollect that Painting and Punctuality mix like Oil and Vinegar, and that Genius and regularity are utter Enemies. - Thomas Gainsborough

..as I met with Mr. (Dunning there. There is something exclusive of the clear and deep understanding of that gentleman most exceedingly pleasing to me. He seems the only man who talks as Giardini plays, if you know what I mean; he puts no more motion than what goes to the real performance, which constitutes that ease and gentility peculiar to damned clever fellows.. .He is an amazing compact man in every respect.. ..and besides this neatness in outward appearance, his storeroom seems cleared of all French ornaments and gingerbread work, everything is simplicity and elegance and in its proper place, no disorder or confusion in the furniture.. ..Sober sense and great acuteness are marked very strong in his face.. ..but there is genius (in our sense of the word). (It) shines in all he says. In short, Mr. Jackson of Exeter [his friend], I begin to think there is something in the air of Devonshire that grows clever fellows. I could name four or five of you, superior to the product of any other county in England.

One part of a picture ought to be like the first part of a tune, that you guess what follows, and that makes the second part of the tune, and so I'm done..

damn gentlemen, there is not such a set of enemies to a real artist in the world as they are, if not kept at a proper distance.. ..They think (and so may you for a while) that they reward your merit by their Company and notice.. ..if they don't stand clear, know that they have but one part worth looking at, and that is their Purse; their Hearts are seldom near enough the right place to get a sight of it..
