One often hears of artists who refuse to be guided by any law or rule of science and who consider that they are law in themselves. If they were students of psychology, the would see that they are absorbing from others, I might even say copying, perhaps subconsciously, but they themselves would be the first to deny this accusation.
Another peculiar fact, those who do not know the laws of nature and who do not put them into their work often make a great success in their youth through their inherent talent, but in later life fall back in the march of progress on account of their lack of early training and absorbed knowledge. Painting and drawing have been taught since the days of Ancient Greece by what is known as "feeling." This is all very well, provided that a sound knowledge of construction, of color, of perspective, and composition, all based on nature's laws, has been learned and absorbed before "feeling" is permitted to be expressed.
