(78) Passing on to the second point, let us search the sacred pages for their teaching concerning the light of nature and this Divine law. (79) The first doctrine we find in the history of the first man, where it is narrated that God commanded Adam not to eat of the fruit of the tree of the knowledge of good and evil; this seems to mean that God commanded Adam to do and to seek after righteousness because it was good, not because the contrary was evil: that is, to seek the good for its own sake, not from fear of evil. (80) We have seen that he who acts rightly from the true knowledge and love of right, acts with freedom and constancy, whereas he who acts from fear of evil, is under the constraint of evil, and acts in bondage under external control. (81) So that this commandment of God to Adam comprehends the whole Divine natural law, and absolutely agrees with the dictates of the light of nature; nay, it would be easy to explain on this basis the whole history or allegory of the first man. (82) But I prefer to pass over the subject in silence, because, in the first place, I cannot be absolutely certain that my explanation would be in accordance with the intention of the sacred writer; and, secondly, because many do not admit that this history is an allegory, maintaining it to be a simple narrative of facts. (83) It will be better, therefore, to adduce other passages of Scripture, especially such as were written by him, who speaks with all the strength of his natural understanding, in which he surpassed all his contemporaries, and whose sayings are accepted by the people as of equal weight with those of the prophets. (84) I mean Solomon, whose prudence and wisdom are commended in Scripture rather than his piety and gift of prophecy. (85) Life being taken to mean the true life (as is evident from Deut. xxx:19), the fruit of the understanding consists only in the true life, and its absence constitutes punishment. (86) All this absolutely agrees with what was set out in our fourth point concerning natural law. (87) Moreover our position that it is the well-spring of life, and that the intellect alone lays down laws for the wise, is plainly taught by, the sage, for he says (Prov. xiii:14): "The law of the wise is a fountain of life" - that is, as we gather from the preceding text, the understanding. (88) In chap. iii:13, he expressly teaches that the understanding renders man blessed and happy, and gives him true peace of mind. "Happy is the man that findeth wisdom, and the man that getteth understanding," for "Wisdom gives length of days, and riches and honour; her ways are ways of pleasantness, and all her paths peace" (xiiii:6, 17). (89) According to Solomon, therefore, it is only, the wise who live in peace and equanimity, not like the wicked whose minds drift hither and thither, and (as Isaiah says, chap. lvii:20) "are like the troubled sea, for them there is no peace."
