If people don't read, that's their choice; a lifelong book habit may itself be some sort of affliction.

Perhaps I shall not write my account of the Paleolithic at all, but make a film of it. A silent film at that, in which I shall show you first the great slumbering rocks of the Cambrian period, and move from those to the mountains of Wales...from Ordovician to Devonian, on the lush glowing Cotswolds, on to the white cliffs of Dover... An impressionistic, dreaming film, in which the folded rocks arise and flower and grow and become Salisbury Cathedral and York Minster.

The place didn't look the same but it felt the same; sensations clutched and transformed me. I stood outside some concrete and plate-glass tower-block, picked a handful of eucalyptus leaves from a branch, crushed them in my hand, smelt, and tears came to my eyes.
