D. B. McLachlan
Best known for a late-19th-century work on logic, this writer explored how reasoning might be rebuilt on the philosophy of George Berkeley. The surviving record is thin, but the book itself shows an ambitious mind trying to rethink how ideas, language, and argument fit together.

About the author
D. B. McLachlan is known today chiefly for Reformed Logic: A System Based on Berkeley's Philosophy with an Entirely New Method of Dialectic, published in 1892. Library and public-domain records consistently identify the book and connect it with McLachlan, but they offer very little confirmed biographical detail about the author.
What can be said with confidence is that McLachlan wrote in the tradition of philosophical logic rather than popular instruction. Reformed Logic presents itself as an effort to explain the workings of mind and reasoning through ideas drawn from George Berkeley, while also proposing a fresh method of dialectic. That makes the work an interesting example of late Victorian philosophical ambition: serious, argumentative, and eager to challenge established systems.
Because reliable sources on the person are so limited, McLachlan remains a somewhat shadowy figure behind the text. For modern listeners and readers, that mystery can be part of the appeal—the sense of encountering an author who survives mainly through a single demanding, thoughtful work.
