Malcolm (Writer on Herbert Spencer) Guthrie

Very little biographical information about this Malcolm Guthrie could be confirmed from reliable sources consulted here. He is identified in library and public-domain records as the author of On Mr. Spencer's Data of Ethics, a book published in 1884 that engages directly with Herbert Spencer’s ideas on ethics.

The surviving record suggests a writer focused less on literary fame than on argument and analysis. In On Mr. Spencer's Data of Ethics, he takes on big questions about morality, human conduct, and the philosophical foundations of Spencer’s system, making him a small but interesting voice in the wider debates of the late Victorian period.

Because dependable personal details are scarce, it is best to treat him as a lightly documented author whose reputation rests almost entirely on this one known work rather than on a well-recorded public life.
