Explanation
This comic satirizes Peter Singer's famous "Shallow Pond" argument, a foundational thought experiment in effective altruism and moral philosophy.
Singer's original argument goes roughly like this: If you walked past a shallow pond and saw a child drowning, you would be morally obligated to wade in and save the child, even if it ruined your expensive clothes. Since you can save children's lives for relatively small charitable donations (e.g., through malaria nets), spending money on luxuries instead of life-saving donations is morally equivalent to walking past the drowning child.
The comic presents a bearded philosopher (resembling a stereotypical academic) at a chalkboard, who lays out the argument step by step:
1. Premise: If you can save a drowning child for a little money, it is immoral not to.
2. From which it follows: spending that money in some other way is morally bad.
3. Thus: whereas pet dogs cost a little money, all pet dogs are bad.
4. But: many pet dogs are "SUCH GOOD BOYS" (emphasized in bold/italics).
5. Therefore: we must reject the premise.
The joke is a parody of philosophical modus tollens (if P implies Q, and Q is false, then P is false). The philosopher constructs a formally valid logical argument but uses the absurd -- yet emotionally compelling -- premise that dogs are "such good boys" to reject Singer's serious moral argument. The humor comes from the collision between rigorous philosophical reasoning and the completely unserious, emotionally driven rejection based on how lovable dogs are.
The caption -- "Disproving the Shallow Pond argument was remarkably simple" -- adds to the joke by treating this transparently silly refutation as a genuine philosophical breakthrough. It also gently mocks how people often find emotionally convenient reasons to reject uncomfortable moral arguments, particularly those that would require them to give up things they enjoy (like pet ownership).
