When we make an appointment to meet someone, we are orientating ourselves within concepts of time and space that have pre-existed us by thousands of years. The very ‘every-day-ness’ of such moments, as philosophers such as Heidegger and Wittgenstein have described, hold unconsidered origins. We tend to be unaware of the history that underpins our actions when we look at our watch, or locate a town on a map. As Wittgenstein put it, all sorts of ‘stage-settings’ have to be put in place before our everyday behavior is comprehensible.
