What are the grounds for the distinction between the mental and the physical? What is it the relation between ascribing mental states to an organism and understanding its behavior? Are animals and complex systems vehicles of inner evolutionary environments? Is there a difference between personal and sub-personal level processes in the brain? Answers to these and other questions were developed in Daniel Dennett's first book, Content and Consciousness (1969), where he sketched a unified theoretical framework for views that are now considered foundational in cognitive science and philosophy of mind.
