We can, we must, jumble up the categories of reform and revolution, preferring change that, though perforce piecemeal, may, in its cumulative effect,… - Roberto Mangabeira Unger

A central thesis of this book is that the connection between thought and practice is most intimately and fully realized only when our minds are addressed to our own affairs—the concerns of humanity. When we direct our thoughts to nature, even if to see ourselves as fixtures of nature, we loosen the connection between thought and practice. When we loosen it, we are tempted to assume the posture I earlier called naturalism. We survey both the human and the nonhuman worlds from a supposedly godlike distance. We treat the achievement of such distance as the realization of our longing for transcendence.

In our advance to a greater life, we confront an initial obstacle. Unless we remove or overcome this obstacle, we can rise no further. We spend our time in a daze of diminished existence, neither awake nor asleep. We resign ourselves to compromise and routine, seeing the world through the categories of the prevailing culture or the methods of established ways of thinking. We reconcile ourselves to the mutilation of our experience that we begin to accept when we entered on a particular course of life. We allow ourselves to be subdued by the carapace of diminished experience that formed around is, as we grew older. For the vast majority of men and women, overwhelming economic necessity and drudgery overwhelm and disguise a stupefaction that would otherwise be apparent. For the increasing number of people who, with the material progress of society, are released from grinding material constraint, there is no disguise. In this way, we cease to live as embodied spirit: as the context-bound but context-resisting agents that we really are. That which is most precious—life itself—we give away in return for nothing. We belittle ourselves, wrongly mistaking our belittlement for a fate as inescapable as our mortality, our groundlessness, and our insatiability.

Humanity takes a long time to understand its relation to its structures of discourse and sociability. People have usually mistaken the forms of inquiry and discourse, exchange and community, to which they are accustomed for flawed approximations to the true face of reason or society. More often than not, they have cast this prejudice aside only to replace it with a more modest, halfhearted reformulation of the same belief.
