Concrescence is the process whereby "the many become one, and are increased by one," i.e., a concrete = subject comes into being by internally relating itself to all objects, including all objects that themselves came into being as subjects at some earlier stage of the same process.
The important concept here is "self-relation." A subject comes into being by internally relating itself to objects, including objects that themselves came into being as subjects.
Another idea important for understanding concrescence is "self-creativity," i.e., the process of self-creation, or self-determination, each new instance of which internally relates itself to previous such instances, upon which it therefore depends, but by which it is not wholly determined.
