Disadvantages of Selfless Care: A Mathematical, Biological, and Historical Proof of Self-Obsession

This thesis advances the claim that self-centredness—the strategy of maximising individual gain without regard to others—is not merely ethically objectionable but formally self-destructive. We prove this claim through three independent and converging arguments: (i) Hamilton's Rule in evolutionary biology establishes that every conspecific carries a non-zero fraction of the actor's genetic material, making harm to others always partial self-harm; (ii) the iterated Prisoner's Dilemma and evolutionary game theory establish that defection is evolutionarily unstable on iterated timescales across all known empirical and simulated models; and (iii) the historical record of civilisational collapse demonstrates that…
