This natural law is the measure of justice. She rests mode comply due to give each his own, to respect the rights of others, etc.. The Classical School of Natural Law The monopoly that the church had throughout the Middle Ages on education, science and religion would be profoundly attacked by the sixteenth-century Protestantism. The postulates were truly revolutionary. You did not need a priest or revelation to access the divine reason.

God as Protestants still ruled the universe but gave the men a greater choice of reasoning to discover through reason which could be the "intentions of God" and even beyond, to discover whether those principles by which God has regulated things . Rationalism was born as a reaction against the Christian philosophy. One of his most important postulates states that it is "reason and not sense the true source of our knowledge." Because the reason usually comes in its operations through deductive (based on clear principles), such as in mathematics, rationalism resolved to adopt as true the deductive method of knowledge and as archetypal science to mathematics. It is considered as the founder of this school to Rene Descartes (1596 – 1650 AD). This philosophical trend obviously has its counterpart in legal terms: Legal Rationalism. Their "starter" was Hugo Grotius (1583 – 1645), but are referred to as true representatives of their positions to Samuel Pufendorf (1632-1694), CRISTIAN TOMASI (1655-1728) AND CHRISTIAN WOLF (1679-1754), along with TOMAS Hobbes, Spinoza, Montesquieu, Locke, Rousseau and so on. Main features of this school are: 1 – all coupled natural law of God; 2 – Natural law is based on reason and is built on reason alone.
