Four years at Harvard had taught him to do this extremely well. Someone once observed to Stevens that college was just an exercise in learning to pass off form as content. This observation had proven correct. Its proof came sophomore year in a tutorial with a senior professor (Steven's department was a small one). A five-page paper properly foot-noted with a perfectly indented bibliography was rewarded; where a classmate's similar paper, bereft of precision but original, was relegated to the B-minus doldrums...
Spokesmen for the consortium argue that Canada has only about seven years of proven natural gas reserves left before it may have to rely on the untapped Mackenzie Delta deposits. A pipeline to the delta would be too massive a financial undertaking for Canada alone. But by hooking up with U.S. gas fields in Alaska, the Canadians can share the costs. The consortium has thoughtfully proposed that the 48-in.-wide pipe be buried, the surface above it revegetated, and the gas refrigerated to prevent melting the permafrost that it would traverse...
Some Canadian economists note that the proven Mackenzie Delta gas reserves are not now large enough to justify Canada's proposed 50% share of the program's cost. And settling claims with the Eskimos and Indians whose ancestral lands the pipeline would cross could cost billions of dollars. "This is essentially a project to transport Alaskan gas to American consumers," says McGill University Economist Eric Kierans...
...under attack as a kind of international legerdemain that is at least partly mere illusion. Critics, including Scoop Jackson and liberal academicians, charge that detente has been unproductive, that Kissinger's personal style of diplomacy pays more attention to principals than principles, that he has neglected relations with such proven allies as Europe and Japan for deals with America's ideological enemies in Moscow and Peking. They are hard problems, partly because final judgments remain to be uncovered by events...
...functional dimension. For too many black students, "blackness" is defined solely within the ritualistic sphere; that is, being one with the Black Geist deals only on the symbolic level. Black cultural uniqueness must be preserved, but it also must invorporate achievement-oriented behavior that has been universally and historically proven to elevate the power-mustering capacity of a people, thereby alleviating the oppression of blacks...
