Explanation
This comic imagines a "Logical Positivist detective show." The scene depicts a classic murder mystery setup: a detective stands in a room with a body on the floor, a woman in a red dress (the classic femme fatale), and evidence. The detective announces that the knife in the victim's back belongs to a suspect, fingerprints are on it, and jewels were found hidden. Then comes the twist: "Unfortunately we cannot make inferences. We have some data and any attempt to go beyond that data is metaphysical nonsense."
The punchline at the bottom reads: "There should be a Logical Positivist detective show."
The humor is rooted in the philosophy of Logical Positivism, a school of thought (associated with the Vienna Circle, including figures like A.J. Ayer and Rudolf Carnap) that held only empirically verifiable statements and tautologies are meaningful -- all else is "metaphysical nonsense." The comic applies this philosophy literally to detective work: even though the evidence overwhelmingly points to the suspect's guilt, a strict logical positivist cannot make the inferential leap from "fingerprints on knife" to "this person committed murder," because induction and inference go beyond the raw sense data.
This is a reductio ad absurdum of strict positivism -- showing that if you truly refused to go beyond raw data, you could never solve a crime, convict anyone, or indeed function in daily life. The detective genre is the perfect vehicle for this joke because detective stories are fundamentally about inference, deduction, and going beyond surface-level evidence.
