True, he said.
And they exchange with one another, and one gives, and another receives, under the idea that the exchange will be for their good.
Very true.
Then, I said, let us begin and create in idea a State; and yet the true creator is necessity, who is the mother of our invention.
Of course, he replied.
Now the first and greatest of necessities is food, which is the condition of life and existence.
Certainly.
The second is a dwelling, and the third clothing and the like.
True.
And now let us see how our city will be able to supply this great demand: We may suppose that one man is a husbandman, another a builder, someone else a weaver—shall we add to them a shoemaker, or perhaps some other purveyor to our bodily wants?
Quite right.
The barest notion of a State must include four or five men.
Clearly.
And how will they proceed? Will each bring the result of his labors into a common stock?—the individual husbandman, for example, producing for four, and laboring four times as long and as much as he need in the provision of food with which he supplies others as well as himself; or will he have nothing to do with others and not be at the trouble of producing for them, but provide for himself alone a fourth of the food in a fourth of the time, and in the remaining three-fourths of his time be employed in making a house or a coat or a pair of shoes, having no partnership with others, but supplying himself all his own wants?
Adeimantus thought that he should aim at producing food only and not at producing everything.
Probably, I replied, that would be the better way; and when I hear you say this, I am myself reminded that we are not all alike; there are diversities of natures among us which are adapted to different occupations.
Very true.
And will you have a work better done when the workman has many occupations, or when he has only one?
