Of the Duties of Man

As they May be Deduced from Nature
Philip Valenti


James Logan's philosophical treatise, of the Duties of Man, as they may be deduced from Nature, was written in the years 1735-c.1737. The 400-page manuscript was considered lost for over 200 years, and only rediscovered in the early 1970s, it is archived at the Historical Society of Pennsylvania. This book is It's first publication. Logan's treatise is extremely significant from many standpoints, not the least of which is It's likely influence on the intellectual development of Benjamin Franklin. Edwin Wolf 2nd characterized it as "the only surviving nontheological tractate on moral philosophy written in colonial America."
