And that is that we all in this room learned how to walk, how to talk, not by being taught how to talk, or taught how to walk, but by interacting with the world, by having certain results as a consequence of being able to ask for something, or being able to stand up and reach it.
这间屋子里的诸位，在学习走路、说话的时候， 不是靠别人教给我们如何说话，或如何走路， 而是通过和周围的世界互动， 是因为我们能够去要东西，或是能够站起来，够到东西了， 通过这些行为导致某种特定的结果.
