From Michael Berkson
I am afraid that Derek Hallam (13 February, p 25) and Paul Parsons (16 January, p 38) are misquoting Alexander Pope.
The quotation correctly reads: “A little learning is a dang’rous thing” – a very different concept to knowledge.
The stanza continues: “Drink deep, or taste not the Pierian spring:/ There shallow draughts intoxicate the brain,/ And drinking largely sobers us again.”
