Do ideas bring about "power"?
Primarily, I may be thinking of a quote about hedonic pleasure, and how these bodily sensations of power "cannot be satisfied unless the agent has a desire for something else than power" (Reginster 2006). I take this to mean power and its experience are second order goods, and agents bring them about indirectly.
Its [the will of the spirit] object thereby is the incorporation of new "experiences," the assortment of new things in the old arrangements--in short, growth; or more properly, the FEELING of growth, the feeling of increased power--is its object.
If you think of the power as identical to the body, then maybe ideas are the first order goods that increase power.
This may be in part to ask whether Nietzsche a utopian and/or idealist in the Marxist sense. He seemed to want a better society for some, and I don't know how he explained how that might come about.
But now idealism was driven from its last refuge, the philosophy of history; now a materialistic treatment of history was propounded, and a method found of explaining man's "knowing" by his "being", instead of, as heretofore, his "being" by his "knowing". From that time forward, Socialism was no longer an accidental discovery of this or that ingenious brain, but the necessary outcome of the struggle between two historically developed classes - the proletariat and the bourgeoisie. Its task was no longer to manufacture a system of society as perfect as possible
Engels, Socialism Utopian and Scientific
It is pretty normal to use 'utopian' in this sense of lacking a scientific explanation of history, which must then be "idealistic", and utopian socialists are often criticised for having nothing but "plans" and ideas for a future society.
