Gender has arisen once before, in the parable of dimensionality. I observed that physical constructs have a propensity to create order or disorder. I also asserted that the various types might be said to experience time differently due to the nature of their construction.
Orderly constructs tend to preserve their state, and so have a more connected experience of time. In a quantum-mechanical sense, the past and future mix together. Even when their state of an orderly construct changes, if it returns to order, it is possible for information, in the form of phase, to be transfered through time across the intervening instability. Through these mechanisms, the past interacts with the future.
Disorderly constructs are the opposite. Unless completely isolated from external influence, their state is continually in flux. Because of this, the transfer of information through time is suppressed. However, without the effect of disorderly constructs, reality falls into stasis. Nothing changes. Nothing grows, and what exists cannot respond to external attack.
There are certain manifestations of this dichotomy in gender physiology and psychology. Brain scans show that, when working math problems, men expend more energy in the grey matter of the brain, where synaptic firings transfer matter from one neuron to the next. Women expend more energy in the axial tracts, where information is transferred, but the configuration of matter is conserved. In our youth, it is a common observation among school age children that girls are calm and focused in class. Boys are disruptive. As adults, men are aggressive and disruptively singular. Women nurture and find deep expression in the maintenance of stable homes and community. This can manifest itself physically: women maintaining close proximity tend to experience synchronization of their menstrual cycles.
