It is necessary that you should become scientific, either by learning from another person, or by discovering yourself the things of which you have a scientific knowledge. If, therefore, you learn from another person, that which you learn is foreign; but what you discover yourself is through yourself, and is your own. Moreover, if you investigate, discovery will be easy, and soon obtained; but if you do not know how to investigate, discovery will be to you impossible. And [right] reasoning indeed, when discovered, causes sedition to cease, and increases concord. For through this the inexhaustible desire of possessing is suppressed, and equality prevails; since by this we obtain what is just in contracts. Hence, on account of this, the poor receive from those who are able to give; and the rich give to those that are in want, both of them believing that through this they shall obtain the equal. This however will be a rule and an impediment to those that act unjustly, viz. that men who possess scientific knowledge will appease their anger, prior to the commission of an injury, being persuaded that the perpetrators of it will not be concealed when it is committed; but that those who do not possess scientific knowledge, becoming manifest in the commission of an injury, will be restrained from acting unjustly.
