[00:18.53]It has been said that everyone lives by selling something. [00:23.16]In the light of this statement, teachers live by selling knowledge, [00:28.12]philosophers by selling wisdom and priests by selling spiritual comfort. [00:35.20]Though it may be possible to measure the value of material goods in terms of money, [00:40.50]it is extremely difficult to estimate the true value of the services which people perform for us. [00:47.94]There are times when we would willingly give everything we possess to save our lives, [00:53.46]yet we might grudge paying a surgeon a high fee for offering us precisely this service. [01:00.53]The conditions of society are such that skills have to be paid for [01:05.27]in the same way that goods are paid for at a shop. [01:09.07]Everyone has something to sell. [01:12.77]Tramps seem to be the only exception to this general rule. [01:18.05]Beggars almost sell themselves as human beings to arouse the pity of passers-by. [01:24.27]But real tramps are not beggars. [01:27.26]They have nothing to sell and require nothing from others. [01:31.67]In seeking independence, they do not sacrifice their human dignity. [01:37.45]A tramp may ask you for money, but he will never ask you to feel sorry for him. [01:43.80]He has deliberately chosen to lead the life he leads and is fully aware of the consequences. [01:51.51]He may never be sure where the next meal is coming from, [01:55.08]but he is free from the thousands of anxieties which afflict other people. [02:01.03]His few material possessions make it possible for him to move from place to place with ease. [02:07.76]By having to sleep in the open, [02:09.88]he gets far closer to the world of nature than most of us ever do. [02:14.97]He may hunt, beg, or steal occasionally to keep himself alive; [02:20.27]he may even, in times of real need, do a little work; [02:24.20]but he will never sacrifice his freedom. [02:27.93]We often speak of tramps with contempt and put them in the same class as beggars, [02:34.26]but how many of us can honestly say [02:36.95]that we have not felt a little envious of their simple way of life [02:40.81]and their freedom from care?
