mans
Explanation
This comic explores the question "Where does consciousness come from?" An alien asks this question, and a human explains: "Same in every intelligent species. From the tiny man in your brain." The alien is confused: "Different brains produce different signals. 'I'm hungry,' 'I want to reproduce,' and the tiny man interprets them." The human elaborates: "You mean this tiny man inside your brain?" The alien replies: "We don't have a tiny man! What do you mean?" The human says: "No, I'm talking about the tiny man inside your brain. Don't you guys have brains?" The alien responds: "Our brains are just like networks of connections." The human asks: "Like a buzzing or something?" The alien says: "I guess so." The human concludes: "Now this is the kind of thinking that would make your tiny man nervous." The alien counters: "Won't you worry if there's a tiny man in your brain who's responsible for making consciousness come from?" The final punchline: "Nice try. It's tiny mans all the way down."
The joke is about the philosophical "homunculus problem" -- one of the classic difficulties in explaining consciousness. If you say consciousness comes from a "little man" (homunculus) inside your brain who interprets signals and makes decisions, you immediately face the question: what gives that little man consciousness? Another, even tinier man inside his brain? This leads to an infinite regress -- "tiny mans all the way down" -- a deliberate echo of the famous "turtles all the way down" anecdote about infinite regress in cosmology. The human in the comic is blissfully unaware that the homunculus theory is considered a logical fallacy in philosophy of mind, and cheerfully embraces the infinite regress as a feature rather than a bug. The alien, who has a more modern (network-based) understanding of cognition, is baffled by this reasoning.
