Notice the intense look of quietly attentive search on the upturned faces of the boy and of the man in the photo above. What are they looking for? Do they know — exactly — what they are attempting to see, or to learn? Or are they — at least in part — discovering what it is that they are seeking through their looking itself?
Searching for information, or seeking for ideas, can often be like this. We may have a sense of the general direction in which we should be looking, yet not quite know exactly what it is we seek.
