Well there have been a lot.. philosopy, polis, democracy, hemlock cup, enlightenment (note the perversion of "the dark enlightenment"), modernity, the resistance (against Nazism), psychoanalysis, postmodernism and critical studies (postmodernism in the genuine sense of the philosophies/theories that you would assign that label to and not in the misguided sense of relativism as arbitrarity; basically continental philosophy, frankfurt school (e.g. adorno horkheimer, habermas) and the french (e.g. foucault, derrida, deleuze (& guattari))

Of course there were also absolutism, colonialism, the jacobines, nazism & facism, to name just a few. Part of western values, from my perspective at least, is an implicit promise, that what happened in the 20th century with facism was the darkest hour, so to speak-> never again
