"In Modern times, it was emphasized that natural law is reasonable, so that even God could not change it, because that would mean contradicting himself as a Great Mind. Natural law was still seen as the source of both morality and law proper, thus not distinguishing between moral and legal" (Political Science. Edited by B.N. Vasiliev, Moscow, Prospekt, 2003, p. 49). Also, a distinction was not always made between natural law and natural law. Some thinkers (G. Grotius, B. Spinoza) they merge into a single, natural source of positive law and the state. Hobbes and Locke insist that the right is, first of all, the freedom to do or not to do something, while the law is necessary – it commands or forbids. Hobbes, defining natural law, emphasizes that it is "the freedom of every human being to use his own powers at his discretion to preserve his own nature, i.e. his own life." The heiress of such an interpretation of natural law can be considered the modern doctrine of human rights" (Political Science Dictionary. St. Petersburg, "Peter", 2004, p. 77).
