As defined by Margaret Boden in 1992:
Taking two disparate ideas and bringing them together to form something new. In a sense, I think of this type of creativity as the realm of metaphor extended beyond the explanatory realm and into the realm of realization. It’s maybe more hegelian (I’m a little out of my league here) in that it’s two ideas coming together to form something higher.
Exploration of conceptual spaces
Creativity loves constraint. This type of creativity happens within, or expands upon, a cultural framework. A bladesmith inventing a new design for a sword. An architect a new design for a home. A new strategy in Chess or Go. A programmer discovering a new algorithm.
Take the conceptual space we just mentioned in exploration and expand upon or change boundaries or constraints of the space itself. This is the realm of The Structure of Scientific Revolutions. It’s a new type of poetry a la e.e. cummings. It’s going from linear books to Choosing Your Own Adventure.
