Nietzsche's Idea of 'Eternal Recurrence'
n Nietzsche's scheme of history and the universe, there is either order or disorder, extremes. He does not see order, so eternal refers to the idea of one will that in increasingly unstable. It is the one will, the will to power, which is eternal and the only commonality across all events. There is no stability the world and life does not develop. The energy of life rises and sinks, becomes organized then dispossesses but remains constant, at equilibrium! There is merely the repeating of high points and the reverse which leads to ever more complex forms of potency. There is no end point or goal, and all events are the same. Nietzsche follows Heraclitus who posited change and a cyclical history of building and destroying. Nietzsche does not follow Heraclitus completely and rejects the idea of inner patterns that endlessly repeat. Instead the world is repetitious, a play, a game without any final state - an endless alternation back and forth, up and down, of transformations, like fire!
Recurrence implies an occurrence, an event, but Nietzsche does not define event. Instead, development is the occurrence of high points; the highest types are forms of existence of the greatest complexity and highest potency and the most energy, but also the most fragile, unstable and least durable which hence lead to a reversal, a sinking. For Nietzsche, the world does not strive for stability or an end point; nothing posited, not even nothing itself, has been reached. Change and becoming, emergence and dissolution, collapse of power relationships and the establishment of new power relationships that reorganize into new systems of increasing complexity and potency. This greater complexity comes under tensions and strains becomes unstable and vulnerable, and collapses. The world he says eternally retraces the general sequence of states, a cyclical pattern of transformations that is eternally self-creating an eternally self-destroying.
The 'eternal return' he says thru Zarathustra is a test; it is the challenge to live without any hope that life and the world will have a different character than they do. Eternal Return is the great culminating idea! It is a selective principle in the service of "strength" (Nietzsche relates will to strength repeatedly, as often as Freud relates the ego to danger) in humans who are capable of enduring it and craving nothing more!
