Utilitarianism tells us to maximize happiness and minimize suffering. That insight is valuable. Results matter. Harm matters. But TST Ethics does not reduce morality to a single calculation.
Flourishing is broader than happiness. It includes biological health, psychological stability, social coherence, and preservation of natural structure. A society that maximizes short-term pleasure but destroys long-term stability is not flourishing.
TST Ethics also refuses to ignore intent and virtue. Character shapes outcomes. If your happiness depends on degrading others, that reveals a deficit in virtue, not a moral victory.
Where utilitarianism often asks, “What produces the most happiness?” TST Ethics asks, “What promotes layered flourishing while reducing unnecessary harm — and what kind of person must I become to act that way?”
