Thiories of the unity of ethics and morals, whose roots are in the ideas of Plato, Aristotle and Thomas Aquinas, see in the law one „higher", „true" law meant to achieve general good and justness in a political community, as well as to contribute to the ethical growth and advancement of man. The goal of such a view of the unity of ethics and morals is to accomplish absolute good. The idea of the natural law is presented as the existence of an unchangeable order as part of the natural world. In the theories of the unity of ethics and law, morality is considered as a must, as something in the domain of imperative, in which an ethically developed personality of man i the highest value of all, and happiness the uppermost good, chosen to serve just him. The need for the unity of law and morals, one discovers in the works of Plato, Aristotle and Thomas Aquinas is based on a simple truth, and that is man's perennial need for the conquest of the absolute good, happiness, his aspiration towards God. Despite the fact that our reality may be „sated", or 'fed up' with law, it „wants" morals, that would be in such a unity of „ correcting" the defects of law, making our reality worth living in. Thus, the necessity to make law and morals closer to each other is the imperative of our time. Man can nether rely on law only, nor found all the principles of „living" in a reality on legal principles. Our reality does not want only a turn, especially in hard cases, to morals, but also to the primordial unity of law and morals. [ABSTRACT FROM AUTHOR]
