What can we do about this but cry to ourselves: "they will never exist any more, or they will exist for others," and do what must be done so that others at least do not go begging?

除了哀怨地自语：“它们将永远不复存在，就算存在也是属于别人的”，我们还能为此做些什么呢？为了使人们至少不必去乞讨，我们必须做些什么呢？

For one thing, one theory is that babies hear other babies cry, because babies are so stupid they think they themselves are crying; if they're crying they must be in some sort of pain so they cry some more."

例如，有理论说婴儿听到别的婴儿哭，因为婴儿都笨得要命,他们以为是自己在哭;,他们会以为自己哭了，那一定是痛了,所以他们就哭得更厉害”
