Knowledge of Rome must be physical, sweated into the system, worked up into the brain through the thinning shoe-leather. ... When it comes to knowing, the senses are more honest than the intelligence. Nothing is more real than the first wall you lean up against sobbing with exhaustion. Rome no more than beheld (that is, taken in through the eyes only) could still be a masterpiece in cardboard - the eye I suppose being of all the organs the most easily infatuated and then jaded and so tricked. Seeing is pleasure, but not knowledge.
