Beyond Subjective and Objective

What defines  the 'subjective' and the 'objective' ? Is it the nature of the domain itself or the mode, attitude and intention regarding such domains ? We might say that we normally have an objective attitude towards that which we usually call 'objective' and a subjective attitude (i.e. 'first-person' ) towards what we usually call 'subjective'.   Philosophically we should investigate the 'objective' domain's dependence on the 'subjective' domain. But most importantly we should investigate (by a shift of perspective and attitude) the 'subjective' domain in a thoroughly objective manner, rather than subjectively as  usual.  This autoreification, autotranscendence (which is in fact both theoretical and practical) is what was possibly at the core of Husserl's phenomenology and at the same time totally at odds with subsequent phenomenology, existentialism, structuralism and postmodernism.
