In the master's thesis, we will look at the history of philosophical understanding of the notion of time. In accordance with the development of the term throughout the history of philosophy, we will outline the changes and particularities that the concept of time possesses in various philosophical traditions and how it is used by different thinkers. But there will not be much emphasis on the summation of thought, we will instead focus on the meaning of time in the canon of thinkers and look at the advancement of the notion of time throughout history and the relationship that an individual interpretation of the meaning of time shows in the ontological construction of the human life in the world and by the way of epistemological self-understanding. In terms of ontological and epistemological characteristics, the conceptual history of time will be roughly divided into four parts: »Mechanics and naturalism«, »Time of metaphysics«, »Phenomenology of time« and »Immanence of temporal being«. In the end, we will try to summarize the time in its conceptual uniqueness. The purpose of the master's thesis is primarily in researching and interpreting the importance of temporality in human life, as well as the presentation of the way humans have treated the passing of time throughout history.
