What does this quote mean?

“Brevity is the soul of wit.”

The line praises compression: saying less can sharpen meaning when the words that remain do real work.

Source note: Hamlet, Act 2, Scene 2; Polonius says this while promising the King and Queen he will be brief, immediately before continuing at comic length. The dramatic irony is part of the line’s context.

“To a poet nothing can be useless.”

Creative attention turns a wide range of experience into material; knowledge that seems unrelated can later supply images, comparisons or instruction.

Source note: Rasselas, Chapter X; spoken by Imlac in his account of learning the poet’s craft through broad observation.

“Of making many books there is no end.”

The ancient observation sounds surprisingly modern: written material can multiply without limit, so discernment matters as much as sheer volume.

Source note: Ecclesiastes 12:12 in the King James Version; excerpt from the verse’s warning about endless book-making and study.

“A little Learning is a dang’rous Thing.”

Partial knowledge can create confidence before understanding has become deep enough to recognize its limits.

Source note: An Essay on Criticism; Pope follows the line with the image of drinking deeply from the Pierian spring.

“Damn with faint praise, assent with civil leer,”

The line describes a subtle form of hostility in which apparent approval is calibrated to diminish rather than support its target.

Source note: Epistle to Dr Arbuthnot; part of Pope’s satirical portrait of Addison/“Atticus,” so it is polemical literary characterization rather than neutral biography.

“There is no such thing as a moral or an immoral book.”

Wilde shifts judgment away from a book’s supposed moral category and toward artistic execution, a deliberately provocative defense of aesthetic criticism.

Source note: The Picture of Dorian Gray, 1891 edition, Preface; one of Wilde’s epigrams about art and books.
