Yet is it more honourable, and just, and upright, and pleasing, to treasure in the memory good acts than bad. - Xenophon

Just as the various trades are most highly developed in large cities, in the same way food at the palace is prepared in a far superior manner. In small towns the same man makes couches, doors, plows and tables, and often he even builds houses, and still he is thankful if only he can find enough work to support himself. And it is impossible for a man of many trades to do all of them well. In large cities, however, because many make demands on each trade, one alone is enough to support a man, and often less than one: for instance one man makes shoes for men, another for women, there are places even where one man earns a living just by mending shoes, another by cutting them out, another just by sewing the uppers together, while there is another who performs none of these operations but assembles the parts, Of necessity, he who pursues a very specialised task will do it best.

In this mood he [Proxenus] threw himself into the projects of Cyrus, and in return expected to derive from this essay the reward of a great name, large power, and wide wealth. But for all that he pitched his hopes so high, it was none the less evident that he would refuse to gain any of the ends he set before him wrongfully. Righteously and honourably he would obtain them, if he might, or else forego them.

The thing is to get them to turn their thoughts to what they mean to do, instead of to what they are likely to suffer.
