At the phenomenal level, consciousness can be described as a singular, unified field of recursive self-awareness, consistently coherent in a particualr way; that of a subject located both spatially and temporally in an egocentrically-extended domain, such that conscious self-awareness is explicitly characterized by I-ness, now-ness and here-ness. The psychological mechanism underwriting this spatiotemporal self-locatedness and its recursive processing style involves an evolutionary elaboration of the basic orientative reference frame which consistently structures ongoing spatiotemporal self-location computations as i-here-now. Cognition computes action-output (...) in the midst of ongoing movement, and consequently requires a constant self-locating spatiotemporal reference frame as basis for these computations. Over time, constant evolutionary pressures for energy efficiency have encouraged both the proliferation of anticipative feedforward processing mechansims, and the elaboration, at the apex of the sensorimotor processing hierarchy, of self-activating, highly attenuated recursively-feedforward circuitry processing the basic orientational schema independent of external action output. As the primary reference frame of active waking cognition, this recursive i-here-now processing generates a zone of subjective self-awareness in terms of which it feels like something to be oneself here and now. This is consciousness. (shrink)

En el presente artículo hacemos una revisión del método neurofenomenólogico de Thomas Metzinger y su capacidad para responder a problemas habituales de filosofía de la mente y evitar dificultades de otros materialismos. Metzinger define estados mentales en función de estados cerebrales, sin embargo, frente al materialismo eliminativo, sí considera como real la experiencia fenoménica y rechaza su reducción conceptual o epistémica. Esta peculiaridad salva su propuesta de críticas como la de José Ignacio Murillo o Graham Harman, que parecen dirigidas a (...) otros tipos de materialismos. Por ello, consideramos necesario repensar las consecuencias éticas de la tajante negación del libre albedrío y la afirmación de la posibilidad de máquinas artificiales conscientes que conlleva la propuesta de Metzinger.
