PART FIRST: ON THE STATE OF LAYMEN

Already in the Fourth Precept of the Decalogue we have spoken concerning the various and mutual offices of Superiors and inferiors. But in the present Treatise we must speak concerning the offices which regard the public good, and especially concerning forensic persons. Hence:

It must be treated 1° concerning the obligations of judges; 2° of advocates and procurators; 3° of officers; 4° of scribes and notaries; 5° of the accuser and the accused; 6° of witnesses; 7° of physicians, surgeons, and pharmacists; 8° of craftsmen and workers. Concerning custodians see n. 776. q. 7°. 822. 823.

But the obligations of merchants and of other men of this kind are sufficiently understood from those things which we have discussed concerning justice and contracts.
