It affords a generous and manly pleasure to conceive a little nation gathering its fruits and tending its herds with fearless confidence, though it lies open on every side to invasion, where, in contempt of walls and trenches, every man sleeps securely with his sword beside him; where all on the first approach of hostility came together at the call to battle, as at a summons to a festal show; and committing their cattle to the care of those whom age or nature has disabled, engage the enemy with that competition for hazard and for glory, which operate in men that fight under the eye of those, whose dislike or kindness they have always considered as the greatest evil or the greatest good.
This was, in the beginning of the present century, the state of the Highlands. Every man was a soldier, who partook of national confidence, and interested himself in national honour. To lose this spirit, is to lose what no small advantage will compensate.
– Samuel Johnson, A Journey to the Western Islands of Scotland (1775).
