Full Idea
Man may no longer praise, no longer blame, for it is nonsensical to praise and blame nature and necessity. Just as he loves a work of art (or a plant) but does not praise it, because it can do nothing about itself, so he must regard human actions.
Gist of Idea
It is absurd to blame nature and necessity; we should no more praise actions than we praise plants or artworks

A Reaction
But humans can 'do something about themselves'. They can read the works of Nietzsche. He overestimates the importance of the loss of free will, when we grasp that there is no such thing.
