DETERMINISM (from the Latin determino, meaning “define”) is a basic philosophical theory about general interdependence and interconditionality of phenomena and processes. This idea was explained for the first time in ancient natural philosophy (atomistic ideas, peripathetic school), in notions about primary origins and elements. Later, it was developed by Persian poet Omar Khayyam, Italian naturalist G. Bruno, and others who believed in the existence of cause and effect as a rational consequence. Laplace’s determinism is the first attempt to generalize and theoretically interpret general deterministic ideas, proposed by Pierre-Simon, Marquise de Laplace, the 18th-century naturalist and philosopher. According to his variant of determinism (sometimes called strict or mechanistic determinism), everything in the contemporary world (and the human being itself, taken as a biological and social creature) is completely caused by previous facts and events. He believed that the unidirectional and dynamic connections of any phenomenon’s states could be described with the help of laws of physics and mechanics. According to Laplace, the universe is utterly rational, and complete knowledge of any given situation permits us to experience with certainty the future and the past of any unit.
