Robert Byron on travel and the senses

“A spiritual necessity…travel must rank with the more serious forms of endeavor. Admittedly there are other ways of making the world’s acquaintance. But the traveler is a slave to his senses; his grasp of a fact can only be complete when reinforced by sensory evidence; he can know the world, in fact, only when he sees, hears, and smells it.”
–Robert Byron, The Road to Oxiana (1937)
