I believe when you bring, say, a plant into a room, everything in that room changes in relation to it. This tension — tension is the only word for it… - Patrick Swift

The idea of objectivity in the evaluation of pictures introduces the concept of rational and scientific assessment. There are some sciences involved in the making and in the study of pictures, but the art itself is finally not a science and will not submit to scientific regimentation because its life depends on the degree to which it is inhabited by mystery, speaks to us of the unknown. It is simply an avoidance of the interesting difficulty to subject the inexplicable to the process of rational explanation. For since the real pleasures of painting and the reality of its meaning exist in the part of its structure which cannot be explained, all suggestions and pretensions at explanation must lead us away from the area of greatest interest. This is to say that such analysis as purports to lay bare the machinery which makes a painting work — makes it a good painting — not only leaves out the most important factor, the element of mystery, but actively denies the reality which is the justification for the art at all.

The only indication of an individual vision is an individual style: "What I seek above all in a picture is a man and not a picture" – Zola

Good painting is not produced by any unintelligent following of inspiration or temperament.
