The identification of the phenomenon of «terrorism» (and many related terms: violence, anger, hostility, destructiveness, etc.) remains relevant in the modern world. Researchers of various sciences (ethologists, psychobiologists, sociobiologists, genetics, psychopathologists, neuropathologists, clinicians, psychiatrists, psychoanalysts, psychologists, sociologists, anthropologists, criminologists, political scientists) have brought some accuracy to the phenomenon of «terrorism». Taking into account the difference in their views, disciplinary traditions and paradigms, it is not surprising that contradictions are present in the definitions of this phenomenon. The aim of this invistigation is to study general difficulties in defining the phenomenon «terrorism». Certain factors are identified as the main difficulties in defining «terrorism». To experience difficulties in defining «terrorism» from more or less related phenomena or processes, such as «terror», «partisan war», «war for national independence», «irredentism», «separatism», etc. Attempts to explain the essence of terrorism with the help of the related concepts of «radicalism», «extremism», «terrorist acts», «politics of terror», etc. also a mistake. As a rule, a dangerous and erroneous simplification of the concept of «terrorism» occurs in order to equate it with Islamic fundamentalism or other concepts. There are a number of more or less similar concepts, for example, «Islamism», «religious nationalism», «Islamic fascism», «Islamic radicalism», «fundamentalist radicalism», etc. The definition of a «terrorist act», adopted by the European Union, is such an example of the application of the relevant concepts instead of the concept of «terrorism». Thus, we have identified a range of difficulties regarding the concept of «terrorism». They include the definition of terrorism, with its components, a listing of terrorist organizations and the distinction between terrorism and the struggle for national independence. The above difficulties illustrate the discrepancies regarding the universal definition of «terrorism».
