>>45Utopia means "non-place", as in, a a place or time where change has become superfluous. The notion of Utopia being a perfect society is derived from this very meaning, because it assumes a society that doesn't change anymore has reached a stable equilibrium. So yes, Marx' communist society and Fukuyama's end of history are very much utopian ideas.
The core of progressivism becomes visible when you see where, Marx, Fukuyama and others in between come together. Their dispute is one of methodology, of how to get there. When one rejects progress, one rejects this destination that all progressivists have chosen for themselves (and others, unfortunately).
>>46Your willingness to answer flatters you. Your answer in
>>45 comes quite close, but misses one important implication. If progressivism is a self-perpetuating process, how does one know when enough is enough, and if one knows, can one even stop it through discourse? The last thing is a particularly tough realisation, because nearly all previous progress was brought about through violence (Westphalia, Glorious Revolution, American/French Revolution, Labour movements, Weimar, Civil Rights,…) The question is: when, in your eyes, the first toxic wave of progressivism starts to crest, how will you stop it?
Pic related takes a shot at illustrating the process in question.
I disagree on your assessment that progressivism is one side of the coin of human nature, since it only became a force of change starting from Modernity. More likely, ideas have great sway over the human mind, and progressivism is an idea that evolved into a flexible and contagious one.
