Robert Francis (1901-1987), "Though a Fool," Collected Poems 1936-1976
(Amherst: University of Massachusetts Press, 1976), p. 254:
The wayfaring man though a fool
Will often fare as well
As one who has been to school
And knows how to scan and spell.
The scholar is melancholy
Too often on his way
While the fool may well be jolly
Though why he cannot say.
The first line seems to recall Isaiah 35.8:
And an highway shall be there, and a way, and it shall be called the way of holiness; the unclean shall not pass over it; but it shall be for those: the wayfaring men, though fools, shall not err therein.
