 In deliberations, a first-person action proposition represents an act. The proposition has a subject-predicate structure and refers directly to the agent, its subject, without the intermediary of a concept of the agent. A centered world represents the proposition. Such a world not only specifies individuals and their properties and relations, but also specifies which individual is the agent and where and when his decision problem arises. Realization of the act is realization of a world with, at its center, the agent at the time and place of his decision problem.
