Another time, Socrates being in the shop of Pistias the armourer, who showed him some corselets that were very well made: "I admire," said Socrates to him, "the invention of these arms that cover the body in the places where it has most need of being defended, and nevertheless are no hindrance to the motions of the hands and arms; but tell me why you sell the suits of armour you make dearer than the other workmen of the city, since they are not stronger nor of better-tempered or more valuable metal?" "I sell them dearer than others," answered Pistias, "because they are better made than theirs." "In what does this make consist?" said Socrates, "in the weight, or in the largeness of the arms? And yet you make them not all of the same weight nor of the same size, but to fit every man." "They must be fit," said Pistias, "otherwise they would be of no use." "But do you not know," replied Socrates, "that some bodies are well-shaped and others not?" "I know it well." "How, then," continued Socrates, "can you make a well-shaped suit of armour for an ill- shaped body?" "It will be sufficient if they are fit for him," answered Pistias; "for what is fit is well made." "You are of opinion, then," added Socrates, "that one cannot judge whether a thing be well made, considering it merely in itself, but in regard to the person who is to use it; as if you said that a buckler is well made for him whom it fits, and in like manner of a suit of clothes and any other thing whatsoever. But I think there is another convenience in having a suit of armour well made." "What do you take that to be?" said Pistias. "I think," answered Socrates, "a suit of armour that is well made does not load the bearer so much as one ill made, even though it weigh as much. For ill-made arms, by pressing too much upon the shoulders, or hanging cumbrous on some other part, become almost insupportable, and greatly incommode the person that weareth them. But those arms which, as they ought, distribute an equal weight to all the parts of the body, that join upon the neck, the shoulders, the breast, the back, and the hips, may be said to be glued to the body, and to weigh nothing at all." "For this," said Pistias, "I value the arms I make. It is true that some choose rather to part with their money for arms that are gilt and finely carved, but if with all this they fit not easy upon them, I think they buy a rich inconveniency." Socrates went on:--"But since the body is not always in the same posture, but sometimes bends, and sometimes raises itself straight, how can arms that are very fit be convenient and easy?" "They never can," said Pistias. "Your opinion therefore is," said Socrates, "that the best arms are not those that are most fit, and fit closest to the body, but those that do not incommode the person that wears them." "You, too, are of the same opinion," replied Pistias, "and you understand the matter aright."
