Have we not seen it?

The power to guess the unseen from the seen, to trace the implication of things, to judge the whole piece by the pattern, the condition of feeling life, in general, so completely that you are well on your way to knowing any particular corner of it-this cluster of gifts may almost be said to constitute experience, and they occur in country and in town, and in the most differing stages of education. If experience consists of impressions, it may be said that impressions are experience, just as (have we not seen it?) they are the very air we breathe.

Therefore, if I should certainly say to a novice, 'Write from experience, and experience only,' I should feel that this was a rather tantalising monition if I were not careful immediately to add, 'Try to be one of the people on whom nothing is lost!'
