All Fools is an early Jacobean era stage play, a comedy by George Chapman that was first published in 1605. The play has often been considered Chapman's highest achievement in comedy: "not only Chapman's most flawless, perfectly balanced play," but "also his most human and large-minded." "Chapman certainly wrote no comedy in which an ingenious and well-managed plot combined so harmoniously with personages so distinctly conceived and so cleverly and divertingly executed.
