Now suppose that we, bearing all this in mind, were to determine, after consideration, that neither of these arts shall any longer be allowed to exercise absolute control either over freemen or over slaves, but that we will summon an assembly either of all the people, or of the rich only, that anybody who likes, whatever may be his calling, or even if he have no calling, may offer an opinion either about seamanship or about diseases--whether as to the manner in which physic or surgical instruments are to be applied to the patient, or again about the vessels and the nautical implements which are required in navigation, and how to meet the dangers of winds and waves which are incidental to the voyage, how to behave when encountering pirates, and what is to be done with the old-fashioned galleys, if they have to fight with others of a similar build--and that, whatever shall be decreed by the multitude on these points, upon the advice of persons skilled or unskilled, shall be written down on triangular tablets and columns, or enacted although unwritten to be national customs; and that in all future time vessels shall be navigated and remedies administered to the patient after this fashion.
