An attempt to explain the ``problem of consciousness'' scientifically, by the prolific popular science writer (A Scientist in the City, 1994, etc.) and NPR commentator. Consciousness is a problem because it is difficult to define scientifically and yet would seem to be the one entity rendering humankind distinct from animals—and from the imminent artificial- intelligence capabilities of computers. Trefil (Physics/George Mason Univ.) easily dispenses with arguments that the DNA of some animals hardly differs from our own, and with the supposedly intelligent behavior of, say, chimpanzees and octopi, since, in the end, the gap between animal and human intelligence is impressively large. Computers prove harder to deal with, however. First, in his most brilliant chapters, Trefil lays out everything science knows about the workings of the human brain: how synapses fire to cause actions such as the resolution of sight, and the tracking of where individual functions, such as muscle control or the perception of motion, are born. With his model established, Trefil then tries to demolish the notion of a computer as a mechanical brain. The brain is not an electrical apparatus, but a chemical one, he points out, and therefore the parallel commonly drawn between the firing of a synapse and the connections between semiconductors is false. And what to do about that sturdy yet poorly understood mechanism known as intuition? Could a machine, no matter how sophisticated, ever manage such a leap? Even so, Trefil acknowledges that science will shortly be able to map every function of the brain and that eventually enough semiconductors, mimicking those functions, might be strung together to equal the brain's huge capacity. Once he does so, only a mystical approach to consciousness can rescue him, but Trefil is at pains to avoid any but strictly empirical arguments. A gallant, moving, but in the end unconvincing argument.

Stricter than, say, Bergen Evans or W3 ("disinterested" means impartial — period), Strunk is in the last analysis...



Privately published by Strunk of Cornell in 1918 and revised by his student E. B. White in 1959, that "little book" is back again with more White updatings.

Stricter than, say, Bergen Evans or W3 ("disinterested" means impartial — period), Strunk is in the last analysis (whoops — "A bankrupt expression") a unique guide (which means "without like or equal").

From the national correspondent for PBS's MacNeil-Lehrer Newshour: a moving memoir of her youth in the Deep South and her role in desegregating the Univ. of Georgia. The eldest daughter of an army chaplain, Hunter-Gault was born in what she calls the ``first of many places that I would call `my place' ''—the small village of Due West, tucked away in a remote little corner of South Carolina. While her father served in Korea, Hunter-Gault and her mother moved first to Covington, Georgia, and then to Atlanta. In ``L.A.'' (lovely Atlanta), surrounded by her loving family and a close-knit black community, the author enjoyed a happy childhood participating in activities at church and at school, where her intellectual and leadership abilities soon were noticed by both faculty and peers. In high school, Hunter-Gault found herself studying the ``comic-strip character Brenda Starr as I might have studied a journalism textbook, had there been one.'' Determined to be a journalist, she applied to several colleges—all outside of Georgia, for ``to discourage the possibility that a black student would even think of applying to one of those white schools, the state provided money for black students'' to study out of state. Accepted at Michigan's Wayne State, the author was encouraged by local civil-rights leaders to apply, along with another classmate, to the Univ. of Georgia as well. Her application became a test of changing racial attitudes, as well as of the growing strength of the civil-rights movement in the South, and Gault became a national figure as she braved an onslaught of hostilities and harassment to become the first black woman to attend the university. A remarkably generous, fair-minded account of overcoming some of the biggest, and most intractable, obstacles ever deployed by southern racists. (Photographs—not seen.)
