Book 2
4
And the work of each thing is its End; from this, therefore, it is plain that the work is a greater good than the state, for the End is the best as being an End, since the greatest good is assumed as an End and as the ultimate object for the sake of which all the other things exist. It is clear, therefore, that the work is a greater good than the state and disposition.
5
But the term work has two meanings; for some things have a work that is something different from the employment of them, for instance the work of architecture is a house, not the act of building, that of medicine health, not the process of healing or curing, whereas with other things their work is the process of using them, for instance the work of sight is the act of seeing, that of mathematical science the contemplation of mathematical truths. So it follows that with the things whose work is the employment of them, the act of employing them must be of more value than the state of possessing them.
6
And these points having been decided in this way,we say that the same work belongs to a thing and to its goodness (although not in the same way): for example, a shoe is the work of the art of shoemaking and of the act of shoemaking; so if there is such a thing as shoemaking goodness and a good shoemaker, their work is a good shoe; and in the same way in the case of the other arts also.
