Hans-Georg Moeller opens our series on the thought of Niklas Luhmann. Prof. Moeller is especially apt for introducing this complex thinker as he has written two books on Luhmann, "From Souls to Systems" and "The Radical Luhmann."We also discuss the theory in an up-to-date context, discussing Prof. Moeller's newest book, "You and Your Profile" which deals with identity in the age of social media. The book can be viewed here: https://cup.columbia.edu/book/you-and-your-profile/9780231196017The theme music was composed by the always amazing Graeda.
