Human moral behaviour ranges from vicious cruelty to deep compassion, and any explanation of morality must address how our species is capable of such a range. Darwin argued that any social animal, with sufficient intellectual capacity, would develop morality. In agreement, I argue that human morality is unique in the animal kingdom not because of any particular moral capacity, but because some very abstract cognitive abilities that are unique to our species are layered on top of phylogenetically older emotional instincts (...) for aggression and for empathy. I review research on several components of empathy, intersubjectivity and theory of mind, detailing which of these capacities is uniquely human, and highlighting relevant neuroanatomy for each ability. Finally, I describe our abstract cognitive abilities for recursion and metarepresentation, and argue that these are uniquely human. When these abilities interact with our older social abilities (empathy, intersubjectivity) we are able to reason abstractly about others' mental states and how to affect them. Thus, it is these abstract cognitive capacities that give us the ability to be both cruel and compassionate, but it is our ancient ability for empathy that keeps us moral. Morality is, in a very real sense, a gift from our ancestors. (shrink)

Evolutionary theories of human cognition should refer to specific times in the primate or hominid past. Though alternative accounts of tool manufacture from Wynn's are possible (e.g., frontal lobe function), Wynn demonstrates the power of archaeology to guide cognitive theories. Many cognitive abilities evolved not in the “Pleistocene hunter-gatherer” context, but earlier, in the context of other patterns of social organization and foraging.

“How should I move forward?” you might ask yourself, as you stand at the threshold confronted by the darkness ahead. Many of us learn from an early age to fear the unfamiliar or the unknown. If the unknown is without light, it can become unjustifiably terrifying. How you approach the unknown is unique, as your first encounter with anything can only really be as an individual. Staring ahead into the black void of “How it is” you may wonder whether to (...) move ahead at all. “How it is” simultaneously embodies the unknown and the familiar. The darkness contained in the structure mimics both the architecture of the turbine hall and a shipping container. “It’s fine!” you reassure yourself. What can possibly be inside? “How it is” is only complete when you, the viewer, enter the black hole”. (shrink)
