The fundamental treatise of the Australian jurist and philosopher John Finnis is one of the most successful and authoritative attempts to reconstruct the classical theory of natural law, taking into account the achievements of modern socio-political and legal philosophy of various directions. The author's concept continues the rich natural law tradition dating back to Aristotle and Thomas Aquinas. J. Finnis identifies certain primary, self-evident, irreducible types of goods, or basic values, such as human life, knowledge, art, play, communication, practical rationality, religion, and justifies the impossibility of abandoning any of these types of goods or neglect some in favor of others, without falling into internal contradiction. In Finnis's interpretation, natural law is those norms of behavior that are necessary for people and societies to achieve good in all its forms. Since its publication in 1980, the book has become a classic and has sparked intense debate that continues to this day.
