# Membranics
A method for separating the internal and external
interests of a sociont or another life form. A functioning membranics
sees to it that nourishment comes in through, and that feces is pressed
out through the membrane in question. Membranics can also be used as a
concept to comprehend the radical difference between extension-neutral
membranes within subphysics. We refer to this form of virtual
relationalism as *subphysical membranics*.
