Think of consciousness as the objective proxy for pure subjectivity. That is, it is a kind of stuff, is in-itself or prakriti, but of a subtle kind determined by ideal parameters rather than material ones. In this way we might try to describe the geometry of consciousness, phenomenologically upstream from more 'objective' objects such as qualia which are pure objectivities devoid of the internal structure needed to model presence. For example there is the size of the time-slice, the 'delta-t' of immediate awareness. If you look closely at this it comes down to a kind of power of persistence, the power to freely retard the flow of ongoing experiences in order to enjoy them. Also here there is the balance between the plus or forward increment of time in the present and the minus or backward increment or tail of the conscious moment. Similarly there is a kind of inherent spatiality to the current mode of presence, its breadth or embrace. What is more clear in this case is that the moments contain a project of self-reference that produces a virtual location of the central 'I' - this is an inveterate feature of most conscious states but probably not a necessary one. It is with reference to the non-thetic 'position' of the 'I' that the conscious moment has spatiality. Qualia theorists associate a hedonic index with their objects which they call 'valence', a term which is insufficiently differentiated to be of much use. The geometry of presence as inherently self-referential means that what is really intended here is value, the worth of a state as determined internally. Value could be thought of as a correlate of will, what you naturally go towards, and in this case what it would mean is the depth to which a particular mode of presence reveals the veritable subject, as if the whole geometry is shifted further upstream, further towards the source of all value. It is a feature of hedonic states that they are more home-like, but there are distinct varieties of this character. The foregoing cover the feeling-perceptual aspects as well as the conative or intentional aspects. There is also an intellectual component, the degree to which a state is cognitively self-transparent, which seems to work in the same way but is less obviously geometric.
