Solomon 14
king of Israel and the son of David -990–-931 BCRelated quotes

“Knowledge is proud that he has learned so much;
Wisdom is humble that he knows no more.”
Source: The Task (1785), Book VI, Winter Walk at Noon, Line 92.
Context: 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.
Books are not seldom talismans and spells.

“Knowledge is proud that it knows so much; wisdom is humble that it knows no more.”

“850. He that talkes much of his happinesse summons griefe.”
Jacula Prudentum (1651)

“Some grief shows much of love,
But much of grief shows still some want of wit.”
