What reason, then, have we for believing that there are such public neutral objects?

那么，我们有什么理由相信有这样一个公共中立的对象呢？

Thus, if there are to be public neutral objects, which can be in some sense known to many different people, there must be something over and above the private and particular sense-data which appear to various people.

因此，如果要有公共中立的对象， 在某种意义上可以为许多不同的人所知， 那么除了对不同的人而言的私人和特定感官数据之外， 还必须有一些东西。
