“One could say that age is to time what place is to space,” says Robert Pogue Harrison, and he’s surprising that with all the attention given by philosophers to time, so few make the connection with age. Even Heidegger, who understood time as “a kind of movement, or kinesis, that allows the phenomenon to appear and be taken up in thought and word” and who recognized that “place, in its situated boundedness, is more primordial than space” - even Heidegger didn’t pay any attention to age. This surprises Harrison because “when it comes to Dasein’s existential determinations, age remains as fundamental as thrownness, projection, fallenness, being-unto-death, and being-with-others”.
