Sociologist: Romantics who claim that people are not born evil but may be made evil by the imperfect institutions that they form cannot be right, for they misunderstand the causal relationship between people and their institutions. After all, institutions are merely collections of people. Which one of the following principles, if valid, would most help to justify the sociologist's argument? ['People should not be overly optimistic in their view of individual human beings.', 'The whole does not determine the properties of the things that compose it.', 'People acting together in institutions can do more good or evil than can people acting individually.', "A society's institutions are the surest gauge of that society's values."]
