In the present lecture I shall attempt the analysis of memory-knowledge, both as an introduction to the problem of knowledge in general, and because memory, in some form, is presupposed in almost all other knowledge.

It is therefore necessary to find some way of bridging the gulf between the world of physics and the world of sense, and it is this problem which will occupy us in the present lecture.

因此，有必要找到某种方法来弥合物理世界和感官世界之间的鸿沟，而这个问题将成为我们本次演讲的主题。

In the remainder of the present lecture I shall state in outline the view which I advocate, and show how various other views out of which mine has grown result from modifications of the threefold analysis into act, content and object.

在本讲的其余部分，我将概述我所提倡的观点，并展示我的观点是如何从对行为、内容和对象的三重分析的修改中得出的。
