is the key point -- our consciously initiated actions can only be governed by the features of our phenomenal world. It is the phenomenal world that poses the essential problem of conscious experience. Here's why. The world that you (or I) consciously experience (the phenomenal world) is, in its irreducible form, a global coherent volumetric space in which you are the egocentric origin of all experience and action. The rich and constantly changing content of your phenomenal world cannot exist outside of your phenomenal 3D space that encompasses it. Whatever your conscious experience, it must be an experience of something somewhere in your egocentric phenomenal world. The problem is that humans have no sensory transducers by which to detect and represent the extended coherent 3D space of the world we live in. This means that the brain must have an innate system of biological mechanisms (most likely neuronal) that provide us with a transparent representation of the world from our privileged egocentric perspective. The existence of this conscious egocentric representation of our personal world is a necessary precondition for the kind of active engagement with the world that Alva Noe describes so well. A final comment. When Noe claims that "... at the present time, we actually can't give any satisfactory explanations about the nature of human experience in terms of the functioning of the brain", it appears that he is unaware of a wealth of recently published findings relating brain events to objective measures of phenomenal experience.
