In “The Assault on Reason” Al Gore excoriates George W. Bush, asserting that the president is “out of touch with reality,” that his administration is so incompetent that it “can’t manage its own way out of a horse show,” that it ignored “clear warnings” about the terrorist threat before 9/11 and that it has made Americans less safe by “stirring up a hornets’ nest in Iraq,” while using “the language and politics of fear” to try to “drive the public agenda without regard to the evidence, the facts or the public interest.”

The administration’s pursuit of unilateralism abroad, Mr. Gore says, has isolated the United States in an ever more dangerous world, even as its efforts to expand executive power at home and “relegate the Congress and the courts to the sidelines” have undermined the constitutional system of checks and balances.

Mr. Gore’s central argument is that “reason, logic and truth seem to play a sharply diminished role in the way America now makes important decisions” and that the country’s public discourse has become “less focused and clear, less reasoned.” This “assault on reason,” he suggests, is personified by the way the Bush White House operates. Echoing many reporters and former administration insiders, Mr. Gore says that the administration tends to ignore expert advice (be it on troop levels, global warming or the deficit), to circumvent the usual policy-making machinery of analysis and debate, and frequently to suppress or disdain the best evidence available on a given subject so it can promote predetermined, ideologically driven policies.
