Futures Literacy (FL) is a capability. A futures literate person has acquired the skills needed to decide why and how to use their imagination to introduce the non-existent future into the present. These anticipatory activities play an important role in what people see and do. Developing a detailed description of this capability to ‘use-the-future’ calls for an analytical framework that can clarify the nature of different anticipatory systems and guide both research into FL and its acquisition as a skill. Such a framework is presented in this chapter, focusing on the sub-set of anticipatory systems and processes that humans use when they consciously imagine the future.
