 Also among those who argue for the primacy of historiography is the architectural historian Mark Jarzombek.The focus of this work is on disciplinary production rather than poetic production, as was the case with Bloom.Since psychology – which became a more or less official science in the 1880s – is now so pervasive, Jarzombek argued, but yet so difficult to pinpoint, the traditional dualism of subjectivity and objectivity has become not only highly ambiguous, but also the site of a complex negotiation that needs to take place between the historian and the discipline.
