Starting from logical patterns in inferences, we broaden our scope to other information-producing actions such as questions and observations. These, too, have valid patterns that can be described using techniques from modern logic. Finally, we discuss the foundational issue of two complementary perspectives on logic: as a description of laws about an unchanging reality, and as a provider of forms of rational social activity.
