Up until the beginning of the 21st century he referred to himself as a Post-Marxist[1][2] alongside István Mészáros and a number of Yugoslav Marxist philosophers who belonged to Praxis School and emigrated to London.

Since in the 21st century the term Post-Marxism has been appropriated by Ernesto Laclau, Chantal Mouffe and their followers, Alexander Tarasov (together with the above-mentioned István Mészáros and Yugoslav philosophers) stopped referring to himself as a Post-Marxist.

In the psychiatric hospital Tarasov was subjected to cruel treatment and (de facto) to torture (beatings, ETC – electroconvulsive therapy, induced hypoglycemia, injection of large doses of neuroleptics) all resulting in severe somatic disorders, which A.Tarasov has been suffering from since his release, leaving him virtually disabled (hypertonia, Ankylosing Spondylitis, liver and pancreas diseases).

In his address to the readers of the first issue A.Tarasov has noted that The House of the Unions makes it its mission to "update Socialist thought" and "create a theory that matches current reality."

[7] Tarasov has penned more than 1100 publications in sociology (mainly on youth studies,[8] education issues and conflict resolution); politology[9] (current politics,[10] political radicalism in Russia and abroad, mass social movements); history (history[11] and theory of revolutionary movement[12] and guerrilla warfare); culturology[13][14] (popular culture issues, intercultural and inter-civilization contradictions); economics[15](comparative research).

In addition to contributing to compiling and editing of these series, Tarasov takes on the role of a science editor and commentator on the works of famous left-wing thinkers: Leon Trotsky,[21] Alain Badiou,[22] Cornelius Castoriadis[23] to name a few.

On November 4, 1995, Tarasov was the victim of an unprovoked assault near his house: after calling him by name, unknown attackers beat him so severely that he lost consciousness (although he tried to defend himself).

[32][33][34][35] Tarasov is known among Russian anarchists as a consistent critic, primarily of the practice of anarchism as fruitless and unpromising, and, to some extent, of its theory as outdated and unscientific.

He criticized the protests from the left, considering them to be the movement of petit bourgeoisie and "consumers' rebellion" alien to the goals and objectives of left-wing forces in Russia and irrelevant to the revolutionary struggle against capitalism.

[44][45] In 2012 A. N. Tarasov left the Scepsis due to ideological and political differences with the majority of its editorial board members, most of whom were the students and followers of Yuri Semenov.

Tarasov's works have been published, apart from Russia, in the US, Canada, United Kingdom, France, Germany, Netherlands, Switzerland, Sweden, Norway, Italy, Spain, Greece, Finland, Hungary, Czech Republic, Serbia, India, Japan, South Korea, Thailand, Singapore, Argentina, Cuba, Panama, South Africa, Morocco, Réunion, New Zealand, Estonia, Latvia, Lithuania, Belarus, Ukraine, Kazakhstan, Moldova, Georgia, Azerbaijan, as well as in unrecognized Transnistria and Donetsk People's Republic.
