“Most of the regularities in culture are not treasures. It’s not all opera and science and fortifications and buildings and ships. It includes all kinds of bad habits and ugly patterns and stupid things that don’t really matter but that somehow have got a grip on a society and that are part of the ecology of the human species in the same way that mud, dirt and grime and fleas are part of the world that we live in. They’re not our treasures. We may give our fleas to our children, but we’re not trying to. It’s not a blessing. It’s a curse, and I think there are a lot of cultural fleas. There are lots of things that we pass on without even noticing that we’re doing it and, of course, language is a prime case of this, very little deliberate intentional language instruction goes on or has to go on.
“Kids that are raised with parents pointing out individual objects and saying, “See, it’s a ball. It’s red. Look, Johnny, it’s a red ball, and this is a cow, and look at the horsy” learn to speak, but so do kids who don’t have that patient instruction. You don’t have to do that. Your kids are going to learn ball and red and horsy and cow just fine without that, even if they’re quite severely neglected. That’s not a nice observation to make, but it’s true. It’s almost impossible not to learn language if you don’t have some sort of serious pathology in your brain.”
