經典科幻文學:《宇宙盡頭的餐館》第19章2
3 Exports: None.
See imports.
4 Population: None.
It is known that there are an infinite number of worlds, simply because there is an infinite amount of space for them to be in. However, not every one of them is inhabited. Therefore, there must be a finite number of inhabited worlds. Any finite number divided by infinity is as near to nothing as makes no odds, so the average population of all the planets in the Universe can be said to be zero. From this it follows that the population of the whole Universe is also zero, and that any people you may meet from time to time are merely the products of a deranged imagination.
5 Monetary Units: None.
In fact there are three freely convertible currencies in the Galaxy, but none of them count. The Altairan Dollar has recently collapsed, the Flaninian Pobble Bead is only exchangeable for other Flaninian Pobble Beads, and the Triganic Pu has its own very special problems. Its exchange rate of eight Ningis to one Pu is simple enough, but since a Ningi is a triangular rubber coin six thousand eight hundred miles across each side, no one has ever collected enough to own one Pu. Ningis are not negotiable currency because the Galactibanks refuse to deal in fiddling small change. From this basic premise it is very simple to prove that the Galactibanks are also the product of a deranged imagination.
6 Art: None.
The function of art is to hold the mirror up to nature, and there simply isn’t a mirror big enough see point one.
7 Sex: None.
Well, in fact there is an awful lot of this, largely because of the total lack of money, trade, banks, art, or anything else that might keep all the non-existent people of the Universe occupied.
However, it is not worth embarking on a long discussion of it now because it really is terribly complicated. For further information see Guide Chapters seven, nine, ten, eleven, fourteen, sixteen, seventeen, nineteen, twenty-one to eighty-four inclusive, and in fact most of the rest of the Guide.
3、宇宙的出口貿易：無
參見進口貿易。
4、字宙的人口：無
衆所周知，宇宙中存在無限多個世界，因爲有無限多的空間來容納它們。然而，並不是每一個世界上都有居民。因此，有人居住的世界的數量必定是有限的。任何一個有限的數字被無限所乘，都接近於無。所以宇宙中所有行星的平均人口鼓可以說是……0，這絲毫也不奇怪。由此推論，整個宇宙的人口數同樣也是……0”。如果你偶爾覺得自己遇見T什麼人，這只是精神錯亂所導致的幻覺而已。
5、宇宙的貨幣單位：無
實際上，銀河系中有三種可以自由兌換的貨幣，但它們不能算數。章牛星元最近崩潰了；弗萊裏恩的帕伯珠只能和其他的弗萊裏恩帕伯珠交換；而特里甘尼克鈈也有它自己的問題：它的匯率，8尼基兌換l鈈，這本來很簡單，但由於尼基是一種三角形的橡膠硬幣，每一條邊都有六千八百英里長，所以從來沒有人集齊過足夠的尼基以兌換1鈈。尼基不是可兌現的貨幣，固爲銀河系銀行拒絕接受幣值過於微小的零鈔。從這個基本前提出發，很容易證明所謂銀河系銀行同樣也是精神錯亂所導致的幻覺。
6、宇宙的藝術：無
藝術的功能是在自然面前豎起一面鏡子，很簡單，沒有足夠大的鏡子——參見第一點。
7、宇宙的性：無
這個嘛，宇宙中的性活動其實是相當頻繁的。主要是因爲不存在錢、貿易、銀行、藝術或者其他任何東西，所以性佔用了宇宙中所有那些其實並不存在的人們的全部精力。
但這一問題不值得在此展開一場漫長的討論，因爲性這玩意兒實在是太過複雜了。如果想了解進一步的信息，請參見《指南》的第7、9、10、1l、14、16、17、19章，以及第2l到第84章——實際上，應該是《指南》內容中的大部分。
