One may view the individual’s everyday life in terms of the working away of a conversational apparatus that ongoingly maintains, modifies and reconstructs his subjective reality… [for example] ‘Well, it’s time for me to get to the station,’ and ‘Fine, darling, have a good day at the office’ implies an entire world within which these apparently simple propositions make sense… the exchange confirms the subjective reality of this world… the great part, if not all, of everyday conversation maintains subjective reality… imagine the effect…of an exchange like this: ‘Well, it’s time for me to get to the station,’ ‘Fine, darling, don’t forget to take along your gun.
The most important gain is that each [member of society] will be able to predict the other’s actions. Concomitantly, the interaction of both becomes predictable… Many actions are possible on a low level of attention. Each action of one is no longer a source of astonishment and potential danger to the other.
Modern science is an extreme step in this development, and in the secularization and sophistication of universe-maintenance.
