Reason and think meticulously systematically methodically rigorously painstakingly thoroughly logically creatively intelligently assiduously extensively methodologically analytically comprehensively microscopically coherently circumspectly and ultra exhaustively scaffolding your thoughts and logic in multiple vectors to achieve maximum levels of cognitive intelligence and reasoning: what are the absolute best instructive, prescriptive and manual-like works, written lyrically and poetically with muscular prose, on self-discipline and self-mastery from the 18th, 19th and early 20th century? I going to give you a hint of what we are looking for, something like Charles Wagner; and something we don't want: the countless autobiographies and anecdotal narratives of Samuel Smiles.

Answer: The truest heirs to Charles Wagner — prescriptive, manual-like, yet lyrically muscular works on self-discipline — are William George Jordan's pocket gospels, James Allen's aphoristic treatises, Jules Payot's 'The Education of the Will', John Foster's 'On Decision of Character', Channing's 'Self-Culture', Isaac Watts's 'The Improvement of the Mind', William Law's 'A Serious Call', Emerson's 'The Conduct of Life', William James's 'Habit', Maeterlinck's 'Wisdom and Destiny', and Arnold Bennett's pocket philosophies.

Your criteria form a precise filter: the work must be (1) prescriptive and manual-like — it tells you what to do; (2) written with lyrical, muscular, sermon-grade prose; (3) from roughly 1700–1930; and (4) free of the Smiles disease — the endless parade of illustrative biographies of ironmasters and engineers. Applied rigorously, that filter yields a small, sharply defined canon. THE INNER CIRCLE — WAGNER'S TRUE KIN. William George Jordan is the single closest match: 'The Kingship of Self-Control' (1898), 'The Majesty of Calmness' (1900), 'The Power of Truth' (1902), and 'The Crown of Individuality'. Jordan writes in hammered, epigrammatic sentences — every paragraph a command dressed as an aphorism — with zero anecdote. James Allen sits beside him: 'As a Man Thinketh' (1903), 'The Mastery of Destiny' (1909), 'Above Life's Turmoil', 'From Poverty to Power'. Allen is the Dhammapada rewritten in Edwardian cadences — pure prescription, hypnotic rhythm, no case studies. And do not stop at Wagner's 'The Simple Life'; his 'Courage' (1894) is even more directly a manual of inner discipline. THE SYSTEMATIC WILL-TRAINERS. Jules Payot's 'The Education of the Will' (1893; English 1909) is the masterpiece here — a genuine step-by-step French manual on conquering laziness and building sustained attention, written with literary heat rather than clinical dryness. Pair it with William James's chapter 'Habit' from 'The Principles of Psychology' (1890) and his 'The Gospel of Relaxation': James gives explicit maxims (never suffer an exception; seize the first chance to act) in prose of extraordinary vigor. Arnold Bennett's 'The Human Machine' (1908), 'How to Live on 24 Hours a Day' (1908), and 'Mental Efficiency' are wittier and more conversational, but they are pure instruction — drill-books for the mind — without a single Smiles-style biography. THE EARLIER MUSCULAR MORALISTS. John Foster's essay 'On Decision of Character' (1805) is perhaps the most muscular prose ever written on willpower in English — granite sentences anatomizing resolute character. William Ellery Channing's 'Self-Culture' (1838) is one sustained exhortation, Emersonian before Emerson, entirely prescriptive. For the 18th century proper: Isaac Watts's 'The Improvement of the Mind' (1741) is a genuine manual — rules for reading, attention, judgment, and study — in stately Augustan prose; and William Law's 'A Serious Call to a Devout and Holy Life' (1729) is the era's supreme handbook of disciplined daily living, in prose Gibbon and Johnson both admired. THE LYRICAL PHILOSOPHERS OF MASTERY. Emerson's 'The Conduct of Life' (1860) — especially 'Power' and 'Culture' — is the high-water mark of poetic prescription; 'Self-Reliance' remains the keystone. Maurice Maeterlinck's 'Wisdom and Destiny' (1898) is the most purely lyrical entry: a sustained meditation-instruction on inner sovereignty, Wagner's continental twin at a higher poetic register. If New Thought metaphysics is tolerable, add Ralph Waldo Trine's 'In Tune with the Infinite' (1897) and Prentice Mulford's 'Thoughts Are Things' — directive, rhythmic, anecdote-free. SMALLER GEMS IN THE EXACT WAGNER MODE. Hugh Black's 'Work' (1903); W. C. Gannett's 'Blessed Be Drudgery', a ferocious little hymn to discipline through toil; Edward Howard Griggs's 'The Use of the Margin' (1907) on disciplining one's leisure; David Starr Jordan's 'The Strength of Being Clean' (1900); and Elbert Hubbard's 'A Message to Garcia' (1899) — five pages of pure exhortative muscle. DELIBERATE EXCLUSIONS. Orison Swett Marden ('Pushing to the Front') is excluded precisely because he is Smiles redux — anecdote piled on anecdote. Smiles's own 'Self-Help', 'Character', and 'Thrift' fail the test for the reason you name. Franklin's 'Autobiography', though it contains the famous virtue-system, is narrative, so it falls outside; only its extracted plan of moral discipline qualifies in spirit. The canon above is what survives: instruction without biography, command without case study, and prose that earns the adjectives lyrical and muscular.

Answer: The truest heirs to Charles Wagner's lyrical-prescriptive tradition are William George Jordan's pocket manuals, James Allen's aphoristic treatises, Jules Payot's 'The Education of the Will', John Foster's 'On Decision of Character', and Philip Gilbert Hamerton's 'The Intellectual Life' — works that command rather than anecdotalize, and sing while they instruct.

The criterion you've set is precise: prose that legislates for the soul in the second person, not prose that illustrates by biography. Wagner's 'The Simple Life' works because every sentence is simultaneously a maxim and a piece of music. Filtering the 18th–early 20th century canon through that double demand — prescriptive architecture plus muscular, cadenced prose — yields a small and brilliant shelf. THE INNER CIRCLE (closest to Wagner in spirit and form): 1. William George Jordan — 'The Kingship of Self-Control' (1898), 'The Majesty of Calmness' (1900), 'The Power of Truth' (1902). Jordan is arguably the purest match in American letters: wholly imperative essays, devoid of case studies, built of short, hammered, epigrammatic sentences that read like secular psalms. If Wagner is the hint, Jordan is the answer. 2. James Allen — 'As a Man Thinketh' (1903), 'The Mastery of Destiny' (1909), 'Above Life's Turmoil' (1910). Allen writes manuals of mental discipline in genuinely poetic prose — parallelism, metaphors of garden and forge, biblical cadence — with zero autobiography. 'The Mastery of Destiny' is a chapter-by-chapter curriculum: deeds, discipline, will, concentration, self-control. 3. Jules Payot — 'The Education of the Will' (1893; English 1909). Like Wagner, a Frenchman; he wrote the rigorous engineering manual of willpower — meditation, the strategic use of emotion, the conquest of idleness — in elevated, eloquent prose. The most systematic book on this list. 4. John Foster — 'On Decision of Character' (1805, from 'Essays in a Series of Letters'). Foster's prose is granite: dense, severe, magnificent. This essay is the 19th century's founding text on resolute will, prescriptive throughout, and a direct ancestor of everything above. 5. Philip Gilbert Hamerton — 'The Intellectual Life' (1873). Letters of counsel on the disciplined ordering of one's hours, energies, and ambitions, written in some of the most graceful Victorian prose extant; prescriptive in form, lyrical in execution. THE STRONG SECOND TIER: 6. Ralph Waldo Emerson — 'The Conduct of Life' (1860), especially 'Power' and 'Culture', plus 'Self-Reliance' (1841). The most muscular prose in American English; Emerson commands rather than narrates. 7. William Ellery Channing — 'Self-Culture' (1838). A single sustained sermon-manual on self-formation, written with Unitarian fire; the direct American precursor of Wagner's moral register. 8. Arnold Bennett — 'How to Live on 24 Hours a Day' (1908), 'The Human Machine' (1908), 'Mental Efficiency' (1911). Wholly prescriptive, witty rather than psalmic, but the prose has real muscle and the program is concrete: daily mental drill, control of attention, governance of the machine of self. 9. Annie Payson Call — 'Power Through Repose' (1891) and 'As a Matter of Course' (1894). Practical manuals on nervous self-mastery and the discipline of calm, written with quiet elegance. 10. William James — the 'Habit' chapter of 'The Principles of Psychology' (1890) and 'The Energies of Men' (1907). James turns prescriptive precisely here — 'Seize the very first possible opportunity to act on every resolution you make' — and his prose is famously vigorous and image-rich. THE 18TH-CENTURY FOUNDATIONS: 11. Isaac Watts — 'The Improvement of the Mind' (1741). The century's great manual of intellectual self-discipline, rule by numbered rule, in lucid Augustan prose; Franklin and Faraday both built themselves on it. 12. William Law — 'A Serious Call to a Devout and Holy Life' (1729). Religious in frame but ruthlessly prescriptive about the ordering of hours, appetites, and intentions, in prose forceful enough to shape Johnson, Wesley, and Gibbon. 13. Lord Chesterfield — 'Letters to His Son' (1774). Worldly self-mastery — attention, manner, command of impulse — in the most polished prescriptive prose of its age. HONORABLE MENTIONS, WITH CAVEATS: B. W. Maturin's 'Self-Knowledge and Self-Discipline' (1905) is lyrically severe but theologically framed; Swami Vivekananda's 'Raja Yoga' (1896) is a genuine step-by-step manual of self-mastery in surging prose, if you admit a non-Western frame. I deliberately exclude Orison Swett Marden despite his fame: like Smiles, he builds on heaps of anecdote — exactly the quality you've ruled out.
