We've begun to turn to

我们开始讨论
Plato's dialogue Phaedo,

柏拉图的对话录《斐多篇》了
and what I started doing last time was sketching

上一节课我们简单的
the basic outlines of Plato's metaphysics--

讲了《斐多篇》形而上学的要点
not so much to give a full investigation of that--

没必要做太深入的研究
clearly we're not going to do that here--

这里我们也不需要那样做
but just to provide enough of the essential outlines

只要对《斐多篇》中形而上学观点的
of Plato's metaphysical views

核心概述有足够的了解
so that we can understand the arguments

我们就可以理解
that come up later in the Phaedo,

《斐多篇》后面的观点
basically all of which or many of which presuppose something--

基本上所有的或者说诸多的这些先决条件
