D. B. McLachlan
A little-known late 19th-century writer of philosophy and logic, this author is remembered for an ambitious attempt to rethink reasoning through the ideas of George Berkeley. The surviving record is sparse, but the work itself points to a serious, original mind interested in how thought, language, and argument fit together.

About the author
Very little biographical information about D. B. McLachlan could be confirmed from the sources available. What can be verified is that McLachlan wrote Reformed Logic: A System Based on Berkeley's Philosophy with an Entirely New Method of Dialectic, published in 1892.
The book sets out to explain the workings of mind and reasoning through a framework influenced by the philosopher George Berkeley. Its title alone shows the scale of the project: not just a manual of logic, but a full attempt to rebuild logical method on different philosophical foundations.
Because so few personal details are clearly documented online, McLachlan remains a somewhat mysterious figure. That mystery is part of the appeal: the author survives mainly through a challenging, thoughtful work that reflects the energetic philosophical debates of the late Victorian period.
