Explanation
The Joke
Two characters are having a philosophical debate about utilitarianism. One character objects that utilitarianism -- the ethical framework that says we should maximize overall happiness -- leads to absurd conclusions. They argue that you cannot reduce morality to "adding up the sum of happiness," that it ignores how moral intuitions are actually rooted in human nature, and that a strict utilitarian framework would create disturbing scenarios (like a universe where it is acceptable to kill Socrates if it produces a net increase in happiness for five other people).
The other character keeps calmly engaging with these objections, ultimately arguing that even if utilitarianism is "kind of depressing," it is still the most honest ethical framework. They suggest that what people call moral intuitions are really just evolved instincts, not deep truths, and that belief in utilitarianism "will make you a better person" because it forces you to think rigorously about consequences. The first character then delivers the punchline: utilitarianism is just "a thanatos of compassion" -- a death-drive dressed up as caring -- and that they prefer to think of morality as "laughing monks" who once "grew the universe's first garden."
The Humor
The comic is a densely packed philosophy joke that works on several levels. The surface humor is in watching two people have an increasingly heated academic debate about ethical theory as if it were a bar argument. The deeper joke is that both characters are somewhat right and somewhat absurd -- the utilitarian is smugly reductive while the anti-utilitarian retreats into mystical romanticism. The final panel's juxtaposition of rigorous ethical philosophy with "laughing monks" growing a garden captures SMBC's signature move: taking an intellectual debate seriously for multiple panels before puncturing it with something unexpectedly poetic or absurd.
References
Utilitarianism is the ethical theory associated with Jeremy Bentham and John Stuart Mill, which holds that the best action is the one that maximizes overall well-being. Compatibilism and moral intuitions are concepts from contemporary moral philosophy. The reference to killing Socrates echoes classic trolley-problem-style thought experiments used to challenge utilitarian ethics. "Thanatos" is the Freudian concept of the death drive.
