Myers opens with a bold disciplinary claim: ethics, to become a science, must follow the historical method and be treated as a branch of human history. He positions his work as an expansion of lectures for advanced history classes, aiming to provide facts of moral life across stages of historic evolution rather than philosophical speculation. The preface explicitly frames the book as a bridge between history departments and moral philosophy, hoping to reinforce ethical idealism behind movements like world peace.

Stoicism's Influence on Roman Rule

Myers devotes substantial attention to Stoicism as a practical force in Roman governance. He credits Stoic ideals with shaping the rule of emperors like Pius and Marcus Aurelius Antoninus, whom he calls “the philosopher upon the throne.” The text asserts that Stoic doctrine of natural equality worked effectively in law, leading to removal of disabilities on women, emancipation of children from paternal authority, and legal protection for slaves. Myers draws a parallel to eighteenth-century Enlightened Despots, suggesting a recurring pattern of philosophy influencing absolute power. The excerpts show he does not merely describe Stoic theory but traces its concrete legal and administrative effects.

The Amelioration of Slavery Under Pagan Emperors

A key case study in the excerpts is the mitigation of slavery before Christianity. Myers identifies multiple causes: Stoic and Greek philosophies, the character of slaves themselves (often equal or superior in intelligence to masters), and the influence of freedmen like Epictetus. He cites specific imperial legislation: Hadrian removed the right to kill slaves willfully; Antoninus Pius made killing a slave murder. The text notes that the slave code of the later pagan Empire exhibited a humaneness contrasting sharply with earlier callousness. Myers also recounts a dramatic episode under Nero where a prefect was murdered by a slave, the Senate condemned four hundred slaves to death, but popular sentiment was so divided that soldiers were needed to enforce the edict.

Method and Scope: Ethics as Historical Science

Myers explicitly limits his task: he gathers and systematizes facts of moral life without encroaching on moral philosophy. The preface quotes Adolf Wuttke that “all morality has the perfect shaping of universal history as its ultimate end” and Leopold von Ranke that Thucydides’ advance lay in perceiving moral constitution as motive force. Myers’s own voice emerges in the claim that the most important part of the historian’s task is to gather facts of moral evolution. The excerpts do not reveal the full chronological sweep, but the preface indicates the work covers earliest written records onward. Readers should expect a narrative organized by historical periods rather than abstract ethical categories.

Myers’s book is best approached as a historian’s contribution to ethics, not a philosopher’s. The excerpts show he prioritizes concrete legal reforms and institutional changes over theoretical debates. Readers interested in how moral ideas translate into law and governance will find detailed examples, particularly from Roman history. The work’s value lies in its systematic presentation of evidence for moral progress within specific historical contexts.
