Concluding:
How can anything will to power?
By positing itself to itself as a ground value.
And you, Nietzscheans, are excellent examples of this. Nothing will be incorporated by you unless you have defined it in your own terms – in the terms made possibly by your self-positing.
This is a prologue to the next phase of the theories development. The question: can one posit oneself in different ways? Self-valuing is the primary activity, absolute to being-subject, but the particular self-value that is posited may very well be more arbitrary, especially as larger entities are concerned, more resource is involved, different contexts are available.
“What matters is the quantum of power that one is” means: what matters is the scope/size/amount of context in which one is able to posit oneself as primary.
As power is context-bound, and a context is a value-system, the essence of power is the capacity to posit oneself as a ground-value. “Fundamental am I to myself, and to what/who else?” This is the question that we self-conscious entities face. We are driven to find the context in which we, as ground-value, determine the greatest good, the highest value.
