The first great American autobiographies both appeared in the 19th century, were born of conflict and written by public men — “The Life and Times of Frederick Douglass” and “The Personal Memoirs of Ulysses S. Grant.”

Since then, what we might call the publishing-industrial complex has turned the reminiscences of our public men and women into a never-ending stream. As former President George W. Bush — barely two years out of office points out in the acknowledgement of his memoir, “Decision Points,” virtually every member of his extended, very political family has published a bestseller, including his parents’ dogs.

Where does Bush’s account of his astonishingly eventful eight years rank in such company? Probably far higher than many of his detractors expected. As Bush writes in “Decision Points,” he enjoys surprising those who underestimate him.

As the title suggests, the former chief executive elected to abandon the usual chronological approach to these volumes (except for a brief, obligatory foray into childhood and school years) in favor of his recollection of his presidency’s key choices and the personal decisions that Bush says prepared him to make them.

Foremost among the latter were his conversion to active Christianity, which he attributes to an after-dinner talk that evangelist Billy Graham gave to the extended Bush family at their Maine compound, and to participation in his male friends’ Crawford, Texas, Bible study group. According to Bush, he continued to read the Bible every morning of his presidency like his daily run, a comforting habit.

Essentially, “Decision Points” confirms many of the better nonfiction accounts of his presidency published while he was in office, particularly Bob Woodward’s four volumes and Robert Draper’s “Dead Certain.” The Bush White House may not have been given to doubts or its chief executive to indecision, but it did have a penchant for ad hoc deliberation, stubborn persistence in the face of failure as in Iraq up to the surge — excessive personal loyalty and for being “blind-sided” by events beyond the unforeseeable tragedy of 9/11.

Nearly midway through “Decision Points,” Bush writes that, “History can debate the decisions I made, the policies I chose, and the tools I left behind. But there can be no debate about one fact: After the nightmare of September 11, America went seven and a half years without another successful terrorist attack on our soil. If I had to summarize my most meaningful accomplishment as president in one sentence, that would be it.”
