The term metaphysical poets was coined by the critic Samuel Johnson to describe a loose group of 17th-century English poets whose work was characterized by the inventive use of conceits, and by a greater emphasis on the spoken rather than lyrical quality of their verse. These poets were not formally affiliated and few were highly regarded until 20th century attention established their importance. Given the lack of coherence as a movement, and the diversity of style between poets, it has been suggested that calling them Baroque poets after their era might be more useful.
In the chapter on Abraham Cowley in his Lives of the Most Eminent English Poets (1779–81), Samuel Johnson refers to the beginning of the seventeenth century in which there "appeared a race of writers that may be termed the metaphysical poets". This does not necessarily imply that he intended metaphysical to be used in its true sense, in that he was probably referring to a witticism of John Dryden, who said of John Donne:
Probably the only writer before Dryden to speak of a certain metaphysical school or group of metaphysical poets is Drummond of Hawthornden (1585–1649), who in one of his letters speaks of "metaphysical Ideas and Scholastical Quiddities".
Nor was Johnson's assessment of 'metaphysical poetry' at all flattering:
When it came to justify his charges with examples, Johnson quoted just three poets: Cowley himself, John Donne and John Cleveland, which is hardly sufficient for such a blanket condemnation. Instead he was repeating the disapproval of earlier critics who upheld the rival canons of Augustan poetry, for though Johnson may have given the Metaphysical 'school' the name by which it is now known, he was far from being the first to condemn 17th century poetic usage of conceit and word-play. John Dryden had already satirised the Baroque taste for them in his "Mac Flecknoe" and Joseph Addison, in quoting him, singled out the poetry of George Herbert as providing a flagrant example.
