The article is based on the dual concepts of theoretical incompleteness in systems science and theoretical incomprehensibility in philosophy previously introduced in the literature. Issues of incompleteness relate to the logical openness of complexity models in their nonequivalence and necessary non-zippable incompletable multiplicity. This concerns the quasi-ness of phenomena and the constructivist nature of models. Theoretically, incomprehensibility is considered in different ways, such as the inexhaustible multiplicity of the constructivist reality corresponding to the logical openness of both the world and (...) of understanding itself and in reference to incomprehensibilities such as questions like the divide between species, cognitive systems, and after-death experience (if any). In conjunction with the need for non-classic, interdisciplinary approaches in science to deal with complexity, unanswerable questions need suitable scientifically updated philosophical reasoning in interdisciplinary humanistic backgrounds to allow for new social representations, understandings, and plausible social imaginary. Such approaches more properly allow for effective philosophical representations of the world. Knowing how to deal with these issues through philosophical reasoning updated to the current scientific levels and humanistic interdisciplinarity allows for higher levels of awareness and new comprehensive philosophical understanding, introducing new powerful social imaginary. Such new philosophical reasoning is expected to allow a conception of the world that is no longer just utilitarian, but theoretically necessarily, and not only concessively respectful of diversity with significant, even self-ethical effects.
