Franklin uses humour to contrast impressive learning with a lack of practical judgement. Tim can name a horse in nine languages, showing considerable linguistic knowledge, yet he cannot recognise the more basic difference between a horse and a cow when making a practical decision. The joke suggests that education is of limited value when knowledge cannot be applied sensibly.

The saying does not dismiss scholarship or language learning. Its target is learning that remains detached from observation, experience and sound judgement. Franklin’s broader point is that genuine understanding involves more than possessing facts or specialised knowledge. A well-educated person should also be able to interpret circumstances and act appropriately. The proverb therefore distinguishes erudition from practical wisdom and warns against mistaking the appearance of learning for competence.
