Travel makes men wiser, but less happy. When men of sober age travel, they gather knowledge, which they may apply usefully for their country; but they are subject ever after to recollections mixed with regret; their affections are weakened by being extended over more objects; and they learn new habits which cannot be gratified when they return home.
Young men, who travel, are exposed to all these inconveniences in a higher degree, to others still more serious, and do not acquire that wisdom for which a previous foundation is requisite, by repeated and just observations at home. The glare of pomp and pleasure is analogous to the motion of the blood; it absorbs all their affection and attention, they are torn from it as from the only good in this world, and return to their home as to a place of exile and condemnation.
Their eyes are forever turned back to the object they have lost, and its recollection poisons the residue of their lives
- Thomas Jefferson, Letter to Peter Carr, 1787
