Peter Berger – Signals of Transcendence [Note: Berger analyzes everyday human experiences to uncover what he calls “signals of transcendence” implicit in them. These signals are signals of a transcendent dimension/world which exists beyond phenomenal reality, the positing of which appears to make sense of everyday human experiences and rescue them from absurdity. Berger denominates the process of drawing out the transcendent implications of these human experiences as “arguments”; we  have read three of these: the argument from ordering (386), from damnation (389), and from humor (393).] Thesis: Taken together, Berger’s “signals of transcendence” (i.e., his three arguments) are/are not convincing “arguments” for the existence of a transcendent world, an “unseen order,” to use the words of William James.
