经典科幻文学:《宇宙尽头的餐馆》第15章1

The Restaurant at the End of the Universe is one of the most extraordinary ventures in the entire history of catering. It has been built on the fragmented remains of… it will be built on the fragmented… that is to say it will have been built by this time, and indeed has been –
One of the major problems encountered in time travel is not that of accidentally becoming your own father or mother. There is no problem involved in becoming your own father or mother that a broadminded and well-adjusted family can’t cope with. There is also no problem about changing the course of history – the course of history does not change because it all fits together like a jigsaw. All the important changes have happened before the things they were supposed to change and it all sorts itself out in the end.
The major problem is quite simply one of grammar, and the main work to consult in this matter is Dr. Dan Streetmentioner’s Time Traveller’s Handbook of 1001 Tense Formations. It will tell you for instance how to describe something that was about to happen to you in the past before you avoided it by time-jumping forward two days in order to avoid it. The event will be described differently according to whether you are talking about it from the standpoint of your own natural time, from a time in the further future, or a time in the further past and is further complicated by the possibility of conducting conversations whilst you are actually travelling from one time to another with the intention of becoming your own father or mother.
Most readers get as far as the Future Semi-Conditionally Modified Subinverted Plagal Past Subjunctive Intentional before giving up: and in fact in later editions of the book all the pages beyond this point have been left blank to save on printing costs.
The Hitch Hiker’s Guide to the Galaxy skips lightly over this tangle of academic abstraction, pausing only to note that the term “Future Perfect” has been abandoned since it was discovered not to be.
To resume:
The Restaurant at the End of the Universe is one of the most extraordinary ventures in the entire history of catering.

宇宙尽头餐馆是整个餐蚀业历史上最非凡的商业冒险之一。它建在破碎的废墟上，它将建在破碎的也就是说，今后，等它建成的时候其实它的的确确已经——
时间旅行中遇到的主要问题之一，并非你碰巧变成了你自己的父亲或者母亲。其实，对一个思想开明、适应性强的家庭来说，变成你自己的父亲或母亲这种问题不难解决。改变历史进程这样的问题同样容易解决——历史进程不会改变，因为它就像一块拼板一样，各部分早就拼好了，契台得严丝合缝。所有重要的改变都早巳发生了，你能改变的只不过是一些小细节而已。到头来，历史进程自会料理好自己，把一切安排得妥妥贴贴的。
主要的问题其实很简单，只是一个语法问题。这方面主要的学术著作是—一唐，史崔特门擞内尔博士的《时间旅行者的1001种时态构成手册》。比方说，某件事本来应该在过去发生在你身上。为了避开这件事，你通过时间旅行向前跳跃了两天。那么，应该用什么时态描述这件事呢，这本书就会告诉你。这件事的时态会有许多变化，变化依据就是：你是基于你目前所处的自然时间点来谈论这件事，还是基于将来的将来的一个时问点，或是将来的过去的一个时间点。如果你在谈论这件事的同时正进行一次时间旅行－－从一个时间段跳跃到另一个时间段，试罔变成你自己的母亲或者父亲——那么，它的时态还会更加复杂化。。
攻读这部学术专著的大部分读者都会读到论述“将来半条件性修饰亚倒装变格过去式虚拟语气意向性时态”的章节，此后才会放弃自己的努力。所以，这本书的再版本中，这一章节之前都是空白，以节约印刷成本。
《银河系漫游指南》轻巧地跳过了这一纠缠不清的学术性抽象概念，只是蜻蜒点水地提了一句：“将来完成时”这个术语因为被发现不可能存在，所以已经被抛弃掉了。
言归正传：
宇宙尽头餐馆是整个餐饮业历史上最非凡的商业冒险之一。
