the most complicated sonnet." The speaker of the poem is addressing his infant son, asleep by his side: Therefore all seasons shall be sweet to thee, Whether the summer clothe the general earth With greenness, or the redbreast sit and sing Betwixt the tufts of snow on the bare branch Of mossy apple-tree, while the nigh thatch Smokes in the sun-thaw; whether the eave-drops fall Heard only in the trances of the blast, Or if the secret ministry of frost Shall hang them up in silent icicles, Quietly shining to the quiet Moon. In 1965, M. H. Abrams wrote a broad description that applies to the Conversation poems: "The speaker begins with a description of the landscape; an aspect or change of aspect in the landscape evokes a varied by integral process of memory, thought, anticipation, and feeling which remains closely intervolved with the outer scene. In the course of this meditation the lyric speaker achieves an insight, faces up to a tragic loss, comes to a moral decision, or resolves an emotional problem. Often the poem rounds itself to end where it began, at the outer scene, but with an altered mood and deepened understanding which is the result of the intervening meditation." In fact, Abrams was describing both the Conversation poems and later poems influenced by them. Abrams' essay has been called a "touchstone of literary criticism". As Paul Magnuson described it in 2002, "Abrams credited Coleridge with originating what Abrams called the 'greater Romantic lyric', a genre that began with Coleridge's 'Conversation' poems, and included Wordsworth's Tintern Abbey, Shelley's Stanzas Written in Dejection and Keats's Ode to a Nightingale, and was a major influence on more modern lyrics by Matthew Arnold, Walt Whitman, Wallace Stevens, and W. H. Auden." Literary criticism Biographia Literaria In addition to his poetry, Coleridge also wrote influential pieces of literary criticism including Biographia Literaria, a collection of his thoughts and opinions on literature which he published in 1817. The work delivered both biographical explanations of the author's life as well as his impressions on literature. The collection also contained an analysis of a broad range of philosophical principles of literature ranging from Aristotle to Immanuel Kant and Schelling and applied them to the poetry of peers such as William Wordsworth.See article on Mimesis Coleridge's explanation of metaphysical principles were popular topics of discourse in academic communities throughout the 19th and 20th centuries,
