Knowledge, a rude unprofitable mass,
The mere materials with which wisdom builds,
Till smoothed and squared and fitted to its place,
Does but encumber whom it seems to enrich.
Knowledge is proud that he has learned so much;
Wisdom is humble that he knows no more.
- -- William Cowper (1731–1800), British poet. represented In Poetical Works, ed. H.S. Milford (1934). The Task, bk. 6, l. 92-7 (1785).
