Ethics
A focused group of public-domain works connected by subject, literary setting and recurring questions.
Independent digital catalogue
This catalogue traces how philosophical questions move through history, connecting works that are often shelved apart. Its four categories—ethics, logic, metaphysics, and political philosophy—are not isolated shelves but linked conversations. You can enter through a single theme, such as the relationship between science and belief, or follow a sequence of texts that build on each other. The 95 works range from classical dialogues to early modern treatises, offering different angles on enduring problems. Each record gives bibliographic details, subject headings, and an editorial note that points to structure and context, helping you find your own path through the collection.

Authored by Authors: Owen, Robert Dale, 1801-1..., 'Owen's Moral Physiology; or, A B...' stands as a notable and significant work within the Ethics category. This 1846 treatise by Robert Dale Owen, edited by Ralph Glover, argues for voluntary control over reproduction through a plain-spoken, physiological lens. It combines Benthamite utility with direct anatomical description and a frontispiece depicting a foundling hospital, moving between abstract moral argument and concrete marital advice. This volume offers essential insights for researchers and enthusiasts alike.
