Modernity's reflexivity provokes activism rather than passive privatism. [causal]
Pragmatic acceptance can be sustained towards most of the abstract systems that impinge on individuals' lives, but by its very nature such an attitude cannot be carried on all the while and in respect of all areas of activity. For incoming expert information is often fragmentary or inconsistent,* as is the recycled knowledge which colleagues, friends, and intimates pass on to one another. On a personal level, decisions must be taken and policies forged. Privatism, the avoidance of contestatory engagement—which can be supported by attitudes of basic optimism, pessimism, or pragmatic acceptance—can serve the purposes of day-to-day "survival" in many respects. But it is likely to be interspersed with phases of active engagement, even on the part of those most prone to attitudes of indifference or cynicism. For, to repeat, in respect of the balance of security and danger which modernity introduces into our lives, there are no longer "others"—no one can be completely outside. Conditions of modernity, in many circumstances, provoke activism rather than privatism, because of modernity's inherent reflexivity and because there are many opportunities for collective organisation within the polyarchic systems of modern nation-states.
