This volume starts from an interdisciplinary expertise of the contributors, and chooses to work on the very origins of conscious qualitative states in perception. The leading research paradigm can be synthesized in 'phenomenology to neurons to stimuli, and backwards', since as a starting point it has taken the phenomenal appearances in the visual field. Specifically, the leading theme of the volume is the co-presence and interaction of diverse types of spaces in vision, like the optical space of psychophysics and of neural elaboration, the qualitative space of phenomenal appearances, and its relation with the pictorial space of art. The contributors to the volume agree in arguing that those spaces follow different rules of organization, whose specific singularity and reciprocal dependence have to be individuated, as a preliminary step to understand the architecture of the conscious awareness of our environment and to conceive its potential implementation in constructing any kind of embodied intentional agents.
