As of late, the author prefers and uses 'Max' or 'Maximiliaan' while his official last name is Drenth. Previous work listed and was published under a multitude of pseudonyms, which could be categorized into two groups of each three names. The initial "M" which sometimes refers to the female side of the author, as Marjolein Drenth or M. Februari and M. Drenth von Februar, and recently the male side of the author, Max.

The same ambivalence is found in Een pruik van paardenhaar & Over het lezen van een boek. Amartya Sen en de onmogelijkheid van de Paretiaanse liberaal which is neither purely a novel nor exclusively as a thesis, although it did fulfill this role as a PhD thesis. The title suggests a dual publication under dual authorship, while in fact, it is a single work under two pseudonyms which refer to a single author.

An earlier novel, De zonen van het uitzicht (1989) was anaemic and bland, but hailed as promising. This was followed by Een pruik van paardenhaar & Over het lezen van een boek. Amartya Sen en de onmogelijkheid van de Paretiaanse liberaal more than a decade later, in 2000. Presenting the work as literary or consisting of both literary and scientific passages is somewhat deluding. The work is a highly cerebral, theoretical and philosophical work on ethics.

Not for ordinary readers, extraordinary, perhaps. ( )
