The Argo’s parts may get replaced, but it’s still called the Argo. We may become more used to jumping into flight, but that doesn’t mean we have done with all perches. We ought to say a feeling of and, a feeling of if, a feeling of but, and a feeling of by, quite as readily as we say a feeling of blue or a feeling of cold. We ought to, but we don’t—or at least, we don’t quite as readily. But the more you do, the more quickly you can recognize the feeling when it comes around again, and hopefully you won’t need to stare as long.
