“Now, penguins are better than monkeys because ‘penguin’ is a very specific term, and ‘monkey’ is very unspecific. If we say ‘monkey’ then different people see different things, maybe a mandrill, maybe a little marmoset, whereas if you say ‘penguin’ then we all picture the same thing. Words are very important—most people don’t know that—and the more specific a word is, the better it is.”
