One should not be too surprised if all is eventually rendered into one. The will to power is superior in its scientific encompassion to all other similar metaphysical propositions. Shopenhauer’s will to survive, Freud’s will to sex, all lack a certain fundamentality, a certain universality, a certain physicality. The Nietzschean will is simply the most convincing that we have so far, theoretically. Logistically, it is impeccable.
Besides, please note that this is a big besides, that to cum the entirety of Nietzschean philosophy up to the will to power, eternal recurrence, ubermensch, is naivete. That is no way to read any philosopher, any book, not even a way to enjoy any film. What counts in Nietzsche is absolutely every elegent line that the man ever wrote, every aphorism of his inform us an individual truth, all of them together explains, applies and proves sumamtions such as the will to power.
Young people are not experienced enough to be inspired by all that Nietzsche has wrote. The fact that they are impressed by the will to power may well be true, but that only means my point just made in the previous scentence. To capitalise Nietzsche’s popularity among youth against the man’s favour, is a classic cheap shot. Nietzsche is deep, my friend, not cheap. Those who find him easy to read, plainly do not dig him with enough depth. There are plenty of him that I can quote for you to chew over again and again for ten years without actually understanding their essence. Knowing how to spell the word ubermensch is not good enough. Writing an essay on the concept, hoping to be done with it, is no better. It takes a life time or two to absorb Nietzsche in full. That is just for reading him, try applying him into life. Whoever accomplish that particular existential task, who can say that I am the Lord reborn and people will believe him, in Nietzschean perspective, will love to believe him.
To say it once more, common philosophical reasoning has little use in analysing Nietzsche, as his philosophy is a grand refutation of it all. You are welcome to join the revolution, all you have to do is to realise that much of your inner most belief and existential following is very much approved by Nietzsche already.
