Perspectivity is only a complex form, of specificness. My idea is that every specific body strives to become master of all space, and to extend its power (its will to power), and to thrust back everything that resists it. But inasmuch as it is continually meeting the same endeavours on the part of other bodies, it concludes by coming to terms with those (by "combining" with those) which are sufficiently related to it—and thus they conspire together for power. And the process continues.

Even in the inorganic world all that concerns an atom of energy is its immediate neighbourhood: distant forces balance each other. Here is the root of perspectivity, and it explains why a living organism is "egoistic" to the core.

Granting that the world disposed of a quantum of force, it is obvious that any transposition of force to any place would affect the whole system—thus, besides the causality of sequence, there would also be a dependence, contiguity, and coincidence.

The only possible way of upholding the sense of the concept "God" would be: to make Him not the motive force, but the condition of maximum power, an epoch; a point in the further development of the Will to Power; by means of which subsequent evolution just as much as former evolution—up to Him—could be explained.
Viewed mechanically, the energy of collective Becoming remains constant; regarded from the economical standpoint, it ascends to its zenith and then recedes therefrom in order to remain eternally rotatory. This "Will to Power" expresses itself in the interpretation in the manner in which the strength is used.—The conversion of energy into life; "life in its highest power" thenceforward appears as the goal. The same amount of energy, at different stages of development, means different things.
That which determines growth in Life is the economy which becomes ever more sparing and methodical, which achieves ever more and more with a steadily decreasing amount of energy.... The ideal is the principle of the least possible expense....
