What is an adult?
Suppose I say an adult is someone who’s 18 years or older, unless the issue is drinking legally, in which case an adult is someone 21 years or older. That’s a start. But we’re not so much interested in legal definitions, as changing conceptions, of what an adult is. You could argue that unless we know what an adult is, we don’t really know what a person is or what a human being is.
