ABSTRACT
The theological matrix of the concept of deus legislator can be seen through the polysemy that expresses it in the seventeenth century: as juridical law, promulgated in order to regulate the comportment of men, the lex naturalis only applies to rational beings. As lex morum, it is the law of the code. The theological and philosophical currents divide themselves in many ways according to the two possible etymologies: on the one hand, a juridical law, that which is written and read and, on the other hand, an eternal law, a law of nature which has particular characteristics and which is a rule for all of creation. St Thomas Aquinas proposes a natural law inherent to nature; the ideas being thus like patterns according to which God proceeded to create the world. This natural law constitutes the expression of divine wisdom, inasmuch as it directs all actions and all movements.
