THE EVOLUTION OF CONSCIOUSNESS

DARWIN, FREUD, AND CRANIAL FIRE--THE ORIGINS OF THE WAY WE THINK

Writing with the same infectious enthusiasm that invests his much of his other work, Ornstein (coauthor, Healthy Pleasures, 1989; Multimind, 1986, etc.) replays familiar themes, adding some new twists. We are basically emotional animals, Ornstein says, acknowledging the importance of Darwin (through his studies of emotional expression and child development) and Freud (in emphasizing the primacy of emotional contexts). Indeed, the book is less about the nature of consciousness and the philosophical dilemmas of the mind/brain problem—very deftly delineated by Daniel C. Dennett in Consciousness Explained (reviewed above)—and more about human evolution and behavior in general. A new twist is the theory that the rapid expansion of the brain (prior to language development) had to do with the need to cool neurons in bipedal animals bereft of the circulatory mechanisms available to quadrupeds. It is a scenario about moving to the warm savannahs, tracking animals in the sun, and evolving more neurons, distributed differently, along with a cunning adaptation of venous flow to protect ultrasensitive nerve cells. Clearly the jury is out on that one. Otherwise, Ornstein reviews findings about right-brain/left- brain differences, visual processing, dreams, ``blindsight,'' subliminal perception, etc., more or less downplaying the role of conscious control and championing the old unconscious systems within us managed by ``simpletons.'' This is his concept of ``multimind'' (not unlike Dennett's ``demons''). Much of the concluding material amounts to a sermon on why we need to move away from bodies evolved to adapt to life 10,000 years ago and toward a new adaptation to the overpopulated, nuclear- threatened, polluted world around us. This will require ``conscious selection''—taking over from simpletons. But how? Yet another Cartesian stage manager, as Dennett might say?

THINKING, FAST AND SLOW

Striking research showing the immense complexity of ordinary thought and revealing the identities of the gatekeepers in our...

A psychologist and Nobel Prize winner summarizes and synthesizes the recent decades of research on intuition and systematic thinking.

The author of several scholarly texts, Kahneman (Emeritus Psychology and Public Affairs/Princeton Univ.) now offers general readers not just the findings of psychological research but also a better understanding of how research questions arise and how scholars systematically frame and answer them. He begins with the distinction between System 1 and System 2 mental operations, the former referring to quick, automatic thought, the latter to more effortful, overt thinking. We rely heavily, writes, on System 1, resorting to the higher-energy System 2 only when we need or want to. Kahneman continually refers to System 2 as “lazy”: We don’t want to think rigorously about something. The author then explores the nuances of our two-system minds, showing how they perform in various situations. Psychological experiments have repeatedly revealed that our intuitions are generally wrong, that our assessments are based on biases and that our System 1 hates doubt and despises ambiguity. Kahneman largely avoids jargon; when he does use some (“heuristics,” for example), he argues that such terms really ought to join our everyday vocabulary. He reviews many fundamental concepts in psychology and statistics (regression to the mean, the narrative fallacy, the optimistic bias), showing how they relate to his overall concerns about how we think and why we make the decisions that we do. Some of the later chapters (dealing with risk-taking and statistics and probabilities) are denser than others (some readers may resent such demands on System 2!), but the passages that deal with the economic and political implications of the research are gripping.

Striking research showing the immense complexity of ordinary thought and revealing the identities of the gatekeepers in our minds.

MASTERY

Readers unfamiliar with the anecdotal material Greene presents may find interesting avenues to pursue, but they should...

Greene (The 33 Strategies of War, 2007, etc.) believes that genius can be learned if we pay attention and reject social conformity.

The author suggests that our emergence as a species with stereoscopic, frontal vision and sophisticated hand-eye coordination gave us an advantage over earlier humans and primates because it allowed us to contemplate a situation and ponder alternatives for action. This, along with the advantages conferred by mirror neurons, which allow us to intuit what others may be thinking, contributed to our ability to learn, pass on inventions to future generations and improve our problem-solving ability. Throughout most of human history, we were hunter-gatherers, and our brains are engineered accordingly. The author has a jaundiced view of our modern technological society, which, he writes, encourages quick, rash judgments. We fail to spend the time needed to develop thorough mastery of a subject. Greene writes that every human is “born unique,” with specific potential that we can develop if we listen to our inner voice. He offers many interesting but tendentious examples to illustrate his theory, including Einstein, Darwin, Mozart and Temple Grandin. In the case of Darwin, Greene ignores the formative intellectual influences that shaped his thought, including the discovery of geological evolution with which he was familiar before his famous voyage. The author uses Grandin's struggle to overcome autistic social handicaps as a model for the necessity for everyone to create a deceptive social mask.

Readers unfamiliar with the anecdotal material Greene presents may find interesting avenues to pursue, but they should beware of the author's quirky, sometimes misleading brush-stroke characterizations.
