[F]orgiveness and trust embody an expansion strategy, by which self-conscious individuals identify with actual goings-on over which they exert some real, but always only partial authority, identify themselves as the seats of responsibilities that outrun their own capacity to fulfill.A Spirit of Trust, p. 623
I have said that to be an agent is to be subject to a certain kind of interpretation, independent of any consideration of causal power in the modern sense. The expansive approach to agency that Brandom recommends accordingly involves an expansive interpretation. Characteristically, he expresses this in terms of identification, authority and responsibility.
When they implement practices of what Brandom calls “postmodern” forgiveness and trust, self-conscious individuals (metonymically substituted for the applicable transcendental syntheses that actually include identification; see Substance Also Subject) are said to identify with actual goings-on. Consistent with Brandom’s expansive strategy, this should mean they identify with actual goings-on tout court, i.e. with everything that happens. This in turn helps with the implementation of normative monism. (See also Normative “Force”; Essentially Self-Conscious?)
The syntheses in question are said to have real partial authority over these same goings-on. Since what is important in an action (as distinct from, say, an event) is its normative status, how that will be evaluated, and what other normative consequences that will have — not first-nature causal efficacy — real but partial authority is all that is required of an agent. As with what was said about identification above, that real but partial authority also extends to everything that happens. A postmodern ethical being functions as a co-steward of the world.
Brandom compares this expansive approach with Leibnizian optimism that we inhabit the best of all possible worlds. For Brandom, realization of this world as the best of all possible worlds is the task postmodern ethical beings set for themselves. Postmodern ethical beings accept co-responsibility for all things, and remain light of heart in doing so.
In the spirit of postmodern heroism, commitment knowingly and happily takes on responsibilities greater than it could possibly fulfill, then does the best it can, freely confesses where it fell short, and rests confident in the knowledge that it deserves to be forgiven for those shortcomings. That is its essential dignity.
