Francis Osborne's chief publication was his 'Advice to a Son,' in two parts, of which the first was published in 1656, 'printed for H. Hath, printer to the university for Thomas Robinson,' and the second in 1658. The first part, which was divided into five sections, headed respectively 'Studies,' 'Love and Marriage,' 'Travel,' 'Government,' and 'Religion,' appeared without any author's name; it at once became popular, and after it had passed through five editions within two years Osborne declared himself the author. In 1658 the second part—of marked inferiority to the first—appeared, and he dedicated it under his own name to Draper, at the same time issuing a new edition of the first part, with his name on the title-page. Like the superior production of Lord Chesterfield, Osborne's book combined in apophthegmatic form some sound sense and perspicuous observation with much that was obvious and commonplace. The warnings against women with which he plied his son form the most interesting passages. The book's misogynic character was ridiculed by John Heydon [q. v.] in his 'Advice to a Daughter, in opposition to Advice to a Son,' 1658, and Heydon's venture produced a defence of Osborne, 'Advice to Balaam's Ass,' by Thomas Pecke [q. v.], whom Heydon castigated in a second edition of his 'Advice to a Daughter,' 1659. In Osborne's day his 'Advice to a Son' found its most enthusiastic admirers among the young scholars at Oxford. 'The godly ministers,' moreover, soon detected 'principles of atheism' in its vague references to religion, and denounced its evil influence both on students and on country gentlemen. On 27 July 1658 the vice-chancellor, Dr. John Conant, accordingly summoned the Oxford booksellers before him, and bade them sell no more copies of Osborne's book; but this direction caused the 'Advice,' according to Wood, to 'sell the better' (Wood, Life, i. 257; Hist, of Oxford).
At a later date Pepys studied it with affectionate care (Diary, 19 Oct. 1661), and Sir William Petty told the diarist that the three most popular books of his time were Osborne's 'Advice,' Browne's 'Religio Medici,' and Butler's 'Hudibras.' Swift wrote of Osborne as one who, affecting the phrases in fashion at court in his day, soon became either unintelligible or ridiculous (Tatler, No. 230). Boswell found the 'Advice' as shrewd, quaint, and lively as an ancient gentleman's conversation. Johnson told Boswell that Osborne was 'a conceited fellow.' 'Were a man to write so now, the boys would throw stones at him.'
Next in interest to Osborne's 'Advice' was his 'Traditional Memoirs of the Reigns of Q. Elizabeth and King James 1,' 1658, 4to, which supplies much attractive court gossip. This tract was reprinted by Sir Walter Scott in his 'Secret History of James I' (Edinburgh, 1811). Other works by Osborne were: 1. 'A Seasonable Expostulation with the Netherlands, declaring their Ingratitude to and the Necessity of their Agreement with the Commonwealth of England,' Oxford, 1652, 4to. 2. 'Persuasive to mutual Compliance under the present Government, and Plea for a Free State compared with Monarchy,' 1652. 3. 'Political Reflections upon the Government of the Turks,' with 'discourses' on Machiavelli, Luther, Nero's death, and other topics, 1656. 4. 'Miscellany of sundry Essays, Paradoxes, Problematical Discourses, Letters, and Characters, together with political Deductions from the History of the Earl of Essex,' London, 1659, 12mo, dedicated to Osborne's niece, Elizabeth Draper. All these works were subsequently bound together, and entitled Osborne's 'Works.' The collective edition of 1673 was brought—without much result—to the notice of the House of Lords on 13 March 1676, on the ground that its incidental vindication of a republican form of government in England rendered it a seditious and treasonable publication. Reissues followed in 1682 (8th edit.), 1689 (9th edit.), 1701 (10th edit.), and 1722, in 2 vols. (11th edit.) To the last are prefixed a memoir of Osborne and many previously unprinted letters addressed by him to Colonel Draper between 1653 and 1658.
Osborne has also been credited, apparently in error, with 'Private Christian's non ultra, or a Plea for the Layman's interpreting the Scriptures,' Oxford, 1650, 4to (anon.); with 'A Dialogue of Polygamy' (London, 16.57, 4to), translated from the Italian of Bernardino Ochino [q. v.] by 'a person of quality,' and dedicated to the author of the 'Advice;' and William Sprigge's 'A modest Plea for an equal Commonwealth against Monarchy,' 1659 (Wood, Athenæ, iv. 561).
