"Alexander Bogdanov was a prominent Russian philosopher, scientist and political activist the end of the XIX century - and the first quarter of the XX. Amongst his numerous scientific achievements, and philosophical conceptions "Tektology", the universal organizational science, is undoubtedly the most significant contribution by Bogdanov to world culture. Not without reason. In Tektology he criticized the philosophical ideas which he propounded at the end of the XIX century and even at the beginning of the XX - including empiriomonism, his main philosophical conception. Bogdanov, until the end of his days, constantly emphasized the radical novelty and universal value of tektology."
