It is not true of the past or the present to say that ‘only the rich or those on vacation can take journeys’. Most men make some journeys. Whether long or short, with an errand or simply to go ‘there and back again’, is not of primary importance. As I tried to express with Bilbo’s Walking Song, even an afternoon-to-evening walk may have important effects. When Sam had got no further than the Woody End he had already had an ‘eye-opener’.
For if there is anything in a journey of any length, for me it is this: the deliverance from the plantlike state of helpless passive sufferer, an exercise however small of will, and mobility- and of curiosity, without which a rational mind becomes stultified.
