Robert Pippin argued that this concept is “neverending” in a book titled for this concept “as a Philosophical Problem.” The “hospitality towards critique” of a form of this concept is likened to a caravanserai in one work. The key dynamics of this concept can be found in all civilizations according to Shmuel Eisenstadt, who developed the idea (15[1])of multiple versions of it. A book titled for this concept argues we should recognize (15[1])the rights of objects in a “Parliament of things.” The shift towards a “risk society” characterizes a (*) “reflexive” (10[1])form of this concept, according to Ulrich Beck and Anthony Giddens. Bruno Latour denied the distinction between nature and culture in his book We Have Never Been [this concept]. A “liquid” form of this concept is the subject of the work of Zygmunt Bauman. For 10 points, name this concept, traditionally thought of as the period of time between the 18th and 20th centuries. ■END■
