The division into genders is the division into generations. The difference between "inside" and "outside" is the difference between "past" and "future". What was inside will be outside; you become what you eat and since each part is incorporating the other the difference is perpetuated.

"Identification, introjection, incorporation, is eating. The oldest and truest language is that of the mouth: the oral basis of the ego. Even in seeing there is an active process of introjection: perception is partaking of what is perceived (Fenichel); we become what we behold (Blake)." Norman O. Brown, Love's Body. 165.

Eating is at once elimination; introjection is projection. To make space within for the good means spatting out the bad. A part is kept and a part is eliminated; its nothing but parts, nothing but roles in a family drama. What we call "life" is the process of extracting and extruding parts from the whole cloth. The process, however, is terminal, and that, my brothers and sisters, is the good news from Harris Creek this sun-filled Sunday in February.
