<logic, philosophy of science> one of Mill's Methods for discovering causal relationships. If an antecedent circumstance is present only on those occasions when a phenomenon occurs, it may be inferred to be the cause of that phenomenon. Example: "Levi and Jarod lived in the same house and were both exposed to the same children at daycare, but only Levi, who also plays T-ball, caught the measles. So Levi probably caught the measles from one of his teammates." Recommended Reading: John Stuart Mill, System of Logic (Classworks, 1986).
