The world of Mozart's operas attempts to achive two goals. On the one hand it describes the mystical jump wich distinguishes the works of a genius from the average standard of its time. On the other hand it intends to characterise the relation between the 'evergreen' authenticity of Mozart’s operas and the specific circumstances of their emergence. The traditional theory of art cannot discover and establish organic connections between the particular historic circumstances of emergence of specific works of art and the possibility of their continuous re-interpretation and overall appeal. Fodor's book makes a geniune effort to reconstruct these organic relations. It traces down the process of realisation of the Enlightenment spirit and moral sensitivity in the forms and dramatics of Mozart’s operas. He therefore offers an alternative approach as opposed to the traditional one which wants to create connections between the raw content of the work of art and its sociological-spiritual equivalent. In this 'philosophical opera-guide' the topic of the investigation is the relation between the spirit of the time and the form of a work of art as it is illustrated and accomplished in six Mozart’s operas.
