Imagination is a classical notion which distinguishes Western philosophy since its ancient genesis and keeps being fundamental in contemporary philosophical research. The notion of imagination means a specific sort of mental representation which is different from perceiving, remembering and believing. Imagining means modelling mental objects which exceedingly help us understand ourselves and other human beings and project both our actions and the objects we are working on by providing us with a powerful guide in the realm of what may be possible, as a sort of bridge between the present and the future we aspire to. Imagination is one of the most promising tools we have at our disposal when we think of both how to act and interact and how to work on the objects we create in science and engineering.
