Darwin among the Machines published

Publication Context. The Press, a daily newspaper in Christchurch, New Zealand, first published on 25 May 1861, served as the venue for Butler's letter. The publication occurred on 13 June 1863. The newspaper is the oldest surviving newspaper in the South Island of New Zealand and the largest circulating daily there.

Core Argument. The letter referenced Charles Darwin's work to argue that machines were a kind of 'mechanical life' undergoing constant evolution. Butler suggested that this evolutionary process could eventually lead to machines supplanting humans as the dominant species, establishing a premise for future discussions on artificial intelligence and biological parallels.

Pseudonym and Format. Butler signed the letter as Cellarius, a pseudonym used in The Press. The piece was formatted as a letter to the editor, published on 13 June 1863. The date and letter-to-the-editor format are stated in the cited passages, which also include a bibliographic reference to a photocopy of the original newspaper article.
