Terrence W. Deacon.
The Symbolic Species: the co-evolution of language and the brain.
Norton. 1997

Drawing on his breakthrough research in comparative neuroscience, Deacon offers a wealth of insights into the significance of symbolic thinking: from the co-evolutionary exchange between language and brains over two million years of hominid evolution to the ethical repercussions that followed man’s newfound access to other people’s thoughts and emotions. In contrast to much contemporary neuroscience that treats the brain as a computer, he provides a new clarity of vision into the mechanism of mind – and a broader view of the adventure of being human.

Incomplete Nature: how mind emerged from matter.
Norton. 2013

As physicists work toward completing a theory of the universe and biologists unravel the molecular complexity of life, a glaring incompleteness in this scientific vision becomes apparent. The “Theory of Everything” that appears to be emerging includes everything but us: the feelings, meanings, consciousness, and purposes that make us what we are. This is an unacceptable omission. We need a “theory of everything” that does not leave it absurd that we exist.

Incomplete Nature begins by accepting what other theories try to deny: that, although mental contents do indeed lack the physical properties that are assumed to be necessary for something to have physical consequences in the world, they are still entirely products of physical processes. And they have an unprecedented kind of causal power that is intrinsically incomplete and therefore unlike anything that physics and chemistry alone have so far explained. The book’s radically challenging conclusion is that we are made of these specific absences—such stuff as dreams are made on—and that what is not immediately present can be as physically potent as that which is. It offers a figure/background shift that shows how even meanings and values can be understood as legitimate components of the physical world.
