The Art of Travel

"Journeys are the midwives of thought. Few places are more conducive to internal conversations than moving planes, ships or trains. There is an almost quaint correlation between what is before our eyes and the thoughts we are able to have in our heads: large thoughts at times requiring large views, and new thoughts, new places. Introspective reflections that might otherwise be liable to stall are helped along by the flow of the landscape...Thinking improves when parts of the mind are given other tasks--charged with listening to music, for example, or following a line of trees. The music or the view distracts for a time that nervous, censorious, practical part of the mind which is inclined to shut down when it notices something difficult emerging in consciousness, and which runs scared of memories, longings and introspective or original ideas, preferring instead the administrative and the impersonal."

~Alain de Botton, The Art of Travel, p. 54
