Time - people have thought about its nature at all times. And they could never find an exact answer. Time was studied with natural science, philosophy, physics, and other sciences. As a result, it was only possible to highlight some of its properties and features. But to give an exhaustive description of the connecting link of the Universe is hardly within the power of the human mind.
In modern natural science and philosophy, time is considered as a basic, but vague concept. It is somewhat reminiscent of the definition of a point in geometry or an element in set theory. If we give the simplest philosophical definition, then time is a kind of irreversible flow from the past into the future. It is inside it that all events and processes occur that generally exist in existing in being.
However, even such an elementary description is too vague. It is not surprising: for many millennia, people have been trying to understand the nature of time, but they have not been able to do this until now. There are only points of view on the time of different cultures, sciences, individuals.
And yet, remaining unknown, time is one of the most important concepts of human thinking. Many great philosophers have considered and still consider it as something objective, but there are also thinkers who define time exclusively as a subjective concept inherent in human consciousness.
At the dawn of human development, the concept of time was cyclical. It was determined by the rising and setting of the sun, the change of seasons, etc. Later, a more perfect, linear idea of time was developed. At the beginning of the 20th century, the connection between time and space was discovered. And the thinkers of the Middle Ages formed a new direction in the study of time, interdisciplinary. It received the name - temporology and united philosophers, scientists, theologians, artists - all those who were interested in the nature of time.
Yet there was an attempt to create a universal theory of time. It was undertaken by J. T. Fraser, president of the International Society for the Study of Time. He published under his editorship fundamental research, which included theoretical and empirical materials from all interdisciplinary studies of time. But they only confirm that it is impossible to consider biological, physical, historical, psychological, philosophical and literary concepts of time from one general point of view.
Nevertheless, over the past three thousand years, various sciences have developed four concepts of the nature of time: relational, substantial, static and dynamic. They differ among themselves in the interpretation of the relationship between time and objects.
