The work The Place of Affectivity and Sexuality in the Shaping of Personal Identity presents as its fundamental core a set of scientific texts – both inter- and trans-disciplinary – reflecting on the definition of personal identity, its configuration as a human task, in which the concrete realities of affectivity and sexuality manifest themselves as unavoidable parts. Aiming to transcend ideologies, that always ignore reality, and fashions of irreflective thinking, this work assumes itself as a contribution for the debate about that which is the foundation of that very special identity, properly human: a totally irreducible personal identity.
