William Angus Knight (1836-1916) was a British writer, born at Mordington, Scotland, and educated at the University of Edinburgh. From 1876 to 1902 he was professor of moral philosophy in the University of St. Andrews. In the field of philosophy his work, editorial and other, includes his collection of Philosophical Classics for English Readers (15 volumes, 1880-90), some of which he wrote. Although he wrote numerous publications, he is probably best known for his works on Wordsworth. His edition of Wordsworth's Works and Life (1881-89) is contained in 11 volumes. He presented to the trustees of Dove Cottage, Grasmere, the poet's former home, all the editions of Wordsworths poems which he possessed.
