Night Thoughts

The Complaint: or, Night-Thoughts on Life, Death, & Immortality, better known simply as Night-Thoughts, is a long poem by Edward Young published in nine parts (or "nights") between 1742 and 1745.

The poem is written in blank verse. It describes the poet's musings on death over a series of nine "nights" in which he ponders the loss of his wife and friends, and laments human frailties. The best-known line in the poem (at the end of "Night I") is the adage "procrastination is the thief of time", which is part of a passage in which the poet discusses how quickly life and opportunities can slip away.

Night-Thoughts had a very high reputation for many years after its publication, but is now best known for a major series of illustrations by William Blake in 1797. A lesser-known set of illustrations was created by Thomas Stothard in 1799.

The nine nights are each a poem of their own. They are: "Life, Death, and Immortality" (dedicated to Arthur Onslow); "Time, Death, Friendship" (dedicated to Spencer Compton); "Narcissa" (dedicated to Margaret Bentinck); "The Christian Triumph" (dedicated to Philip Yorke); "The Relapse" (dedicated to George Lee); "The Infidel Reclaim'd" (in two parts, "Glories and Riches" and "The Nature, Proof, and Importance of Immortality"; dedicated to Henry Pelham); "Virtue's Apology; or, The Man of the World Answered" (with no dedication); and "The Consolation" (dedicated to Thomas Pelham-Holles).

In his Life of Samuel Johnson. James Boswell called Night-Thoughts "the grandest and richest poetry that human genius has ever produced."

William Blake was commissioned in 1795 to illustrate Night-Thoughts for a major new edition of the poem to be published by Richard Edwards. Blake began by making a series of 537 watercolour illustrations from which he planned to engrave about 200 for publication. The first volume – with forty-three engravings by Blake – was published in 1797, but it was a commercial failure and the expensive publishing venture was abandoned.
