One is always finding out more. - James McNeill Whistler

A group from Glasgow sought in 1891 to purchase his portrait of w:Thomas Carlyle was shocked that Whistler's price was 1000 guineas. A spokesman countered that the portrait was not even life size. Whistler replied, 'But, you know, few men are life size.'

[another part / version of Whistler's lecture:]
Nature contains the elements, in colour and form, of all pictures, as the keyboard contains the notes of all music. But the artist is born to pick, and choose, and group with science, these elements, that the result may be beautiful—as the musician gathers his notes, and forms his chords, until he bring forth from chaos glorious harmony. To say to the painter, that Nature is to be taken as she is, is to say to the player, that he may sit on the piano. That Nature is always right, is an assertion, artistically, as untrue, as it is one whose truth is universally taken for granted. Nature is very rarely right, to such an extent even, that it might almost be said that Nature is usually wrong: that is to say, the condition of things that shall bring about the perfection of harmony worthy a picture is rare, and not common at all.

Shall the painter then.. ..decide upon painting? Shall he be the critic and sole authority? Aggressive as is this supposition, I fear that, in the length of time, his assertion alone has established what even the gentleman of the quill accept as the canons of art, and recognize as the masterpieces of work. Seurat's painting of the Grande Jatte proved extremely influential.
