据说每个人都是靠出售某种东西为生的。
It has been said that everyone lives by selling something.
根据这一说法，教师靠出售知识为生，哲学家靠出售智慧为生，而牧师则靠出售精神慰藉为生。
In the light of this statement, teachers live by selling knowledge, philosophers by selling wisdom and priests by selling spiritual comfort.
尽管用金钱衡量物质产品的价值或许是可能的，但要估算出人们为我们提供的服务的真正价值，却极为困难。
Though it may be possible to measure the value of material goods in terms of money, it is extremely difficult to estimate the true value of the services which people perform for us.
有时候，我们愿意倾其所有来挽救自己的生命，然而我们却可能不愿意向一位外科医生支付高额费用——而他所提供的，恰恰就是这种服务。
There are times when we would willingly give everything we possess to save our lives, yet we might grudge paying a surgeon a high fee for offering us precisely this service.
社会条件就是如此，以至于技能必须被付费购买，就像在商店里购买商品一样。
The conditions of society are such that skills have to be paid for in the same way that goods are paid for at a shop.
每个人都有东西可以出售。
Everyone has something to sell.
流浪汉似乎是这一普遍规律的唯一例外。
Tramps seem to be the only exception to this general rule.
乞丐几乎是在把自己作为人来出售，以此唤起过路人的同情。
Beggars almost sell themselves as human beings to arouse the pity of passers-by.
但真正的流浪汉不是乞丐。
But real tramps are not beggars.
他们没有什么可以出售的，也不向他人索取任何东西。
They have nothing to sell and require nothing from others.
在追求独立的过程中，他们并没有牺牲自己的人格尊严。
In seeking independence, they do not sacrifice their human dignity.
一个流浪汉可能会向你要钱，但他绝不会让你同情他。
A tramp may ask you for money, but he will never ask you to feel sorry for him.
他是经过深思熟虑才选择过这种生活的，并且完全清楚这样做的后果。
He has deliberately chosen to lead the life he leads and is fully aware of the consequences.
他可能永远不知道下顿饭从哪里来，但他却摆脱了困扰其他人的成千上万种忧虑。
He may never be sure where the next meal is coming from, but he is free from the thousands of anxieties which afflict other people.
他少得可怜的那几件物质财产，使他得以轻松自如地四处流动。
His few material possessions make it possible for him to move from place to place with ease.
由于不得不在露天睡觉，他与自然界的距离，比我们大多数人所能做到的要近得多。
By having to sleep in the open, he gets far closer to the world of nature than most of us ever do.
他可能偶尔去打猎、乞讨或偷窃来维持生存；甚至在真正困难的时候，他可能还会做一点儿活；但他绝不会牺牲自己的自由。
He may hunt, beg, or steal occasionally to keep himself alive; he may even, in times of real need, do a little work; but he will never sacrifice his freedom.
我们常常带着蔑视的眼光谈论流浪汉，把他们和乞丐归为同一类，但我们当中有几个人能够坦诚地说，自己从来没有对他们那种简朴的生活方式和无忧无虑的自由感到过一丝羡慕呢？
We often speak of tramps with contempt and put them in the same class as beggars, but how many of us can honestly say that we have not felt a little envious of their simple way of life and their freedom from care?
