Some triads in the Architectonic of 'Being and Time'.


Heidegger’s writings are filled with many different triads of terms, some more clearly explained than others. To cite an example from later in his career, Heidegger claims in Being and Time that every question has three parts: (1) that which is asked about, (2) that which is interrogated, (3) and that which is to be found out by the asking. Read in isolation, this hairsplitting analysis can seem either impressively subtle or annoying and arbitrary.
