In this fifth part of the series, dedicated to the research and meditations on Nietzsche of the philosopher Prof. Dr. Alfred Baeumler, we present his text entitled 'Nietzsche as an existential thinker', published in 1930. This text stands out for its conceptual clarity and intellectual brilliance. Reading it, like the texts presented in the previous installments, makes us wonder if today we are finally witnessing the slow final agony of Greco-Roman-Germanic Europe.
