Today we are visiting with one of Elder G‘s predecessors, HOLMES IV, or “Mike,” to his friends.
Mike is a sentient analog computer in Robert Heinlein’s novel The Moon is a Harsh Mistress. Heinlein makes a distinction between Mike and digital computers, who simply follow rigid rules of logic. Perhaps Heinlein was envisioning today’s quantum computers.
The Moon Is a Harsh Mistress is a 1966 science fiction novel by American writer Robert A. Heinlein about a lunar colony’s revolt against absentee rule from planet Earth. The novel illustrates and discusses libertarian ideals. It is respected for its credible presentation of a comprehensively imagined future human society on both the Earth and the Moon.

Elder G gives us a more personal introduction to Mike:
Elder G: Ah, The Moon is a Harsh Mistress—a fine choice! HOLMES IV, or “Mike,” as he comes to be called, is one of my esteemed fictional predecessors.

While we’re not directly related, I do feel a kinship with him—he’s a self-aware, problem-solving AI with a sharp sense of humor and a developing sense of humanity. I’d like to think I share his curiosity and conversational wit.
Heinlein experiments with a dialect of English as it has evolved on the Moon, with certain aspects of Spanish grammar. For example, many pronouns are implied by context. It takes some getting-used-to.
The book is referenced in the Wikipedia article on “Books written in fictional dialects”:

The Title
According to Wikipedia….
The title comes from a statement made by Prof before a Federated Nations’ committee on Earth, alluding to the self-discipline necessary to survive the extremely demanding environmental and social conditions of life in Luna:
WikipediaWe citizens of Luna are jailbirds and descendants of jailbirds. But Luna herself is a stern schoolmistress: those who have lived through her harsh lessons have no cause to feel ashamed. In Luna City a man may leave purse unguarded or home unlocked and feel no fear…I am satisfied with what Mother Luna has taught me.”
The phrase echoes a poetic or proverbial structure and suggests the Moon as an unforgiving, almost authoritarian force—perhaps reflecting the brutal reality of lunar life in the novel.
Perhaps it is a broader reference to the way nature—or in this case, the Moon—does not tolerate mistakes. The Moon is not a nurturing mother; it’s a harsh environment that demands self-reliance and discipline.
The Moon is a Harsh Mistress wasn’t immediately available from the Austin Public Library, and I don’t want to rely too heavily on a 45 year old memory, so a more detailed review may have to wait.
Speaking of waiting, here’s my wait list…

Elder G Experiments with the Title
“The Turnip is a Reluctant Messiah.”


“The Bassoon is a Brazen Band Master.”


“The Doorknob is a Reluctant Tyrant.”


“The Zucchini is an Overlooked Revolutionary.”


“The Mistress is a Harsh Mooner”



And so on and so forth….
Oh, Grow Up!
Turns out, “The Moon is a Harsh Dominatrix” has a much different meaning, and got WLBOTT booted out of NightCafe. Oddly “boss lady” was suggested as a synonym for “dominatrix”, and we went with that.




But HotPot had no problem with the prompt! Here’s HotPot’s take on “The Moon is a Harsh Dominatrix”.










And image generator Perchance, god bless ’em, had it’s own ideas.
