Summoning the soul of the nation, President Obama on Wednesday implored Americans to honor those slain and wounded in the Arizona shooting rampage by becoming better people, telling a polarized citizenry that it is time to talk with one another "in a way that heals, not in a way that wounds."
After a hospital bedside visit with Rep. Gabrielle Giffords, target of the assassination attempt, he said: "She knows we're here, and she knows we love her."
In a memorably dramatic moment, the president said that Giffords, who on Saturday was shot point-blank in the head, had opened her eyes for the first time shortly after his hospital visit. First lady Michelle Obama held hands with Giffords' husband, Mark Kelly, as the news brought soaring cheers throughout the arena.
Speaking at a memorial at the University of Arizona, Obama bluntly acknowledged that there is no way to know what triggered the rampage that left six people dead, 14 wounded and the nation shaken. He tried instead to leave indelible memories of the people who were gunned down and to rally the nation to use the moment as a reflection on its behavior and compassion.
"I believe we can be better," Obama said to a capacity crowd of more than 14,000 in the university's basketball arena -- and to countless others watching across the country.
"Those who died here, those who saved lives here -- they help me believe," the president said. "We may not be able to stop all evil in the world, but I know that how we treat one another is entirely up to us."
In crafting his comments, Obama clearly sought a turning point in the raw debate that has defined national political discourse.
After offering personal accounts of every person who died, he challenged anyone listening to think of how to honor their memories, and he was not shy about offering direction. He admonished against any instinct to point blame or to drift into political pettiness or to latch onto simple explanations that may have no merit.
"At a time when our discourse has become so sharply polarized -- at a time when we are far too eager to lay the blame for all that ails the world at the feet of those who think differently than we do -- it's important for us to pause for a moment and make sure that we are talking with each other in a way that heals, not a way that wounds," the president said.
In an unscheduled stop shortly after landing in Arizona, Obama spent about 10 minutes with Giffords and her husband in her hospital room. The president and the first lady also met with other victims wounded in the rampage before moving to the site of the memorial, where they gathered with families of those who were killed.
The shooting happened as Giffords, a three-term Democrat who represents southern Arizona, was holding a community outreach event in a Tucson shopping center parking lot Saturday. A gunman shot her in the head and worked his way down the line of people waiting to talk with her, law enforcement officials said. The attack ended when bystanders tackled the man, Jared L. Loughner, 22, who is in custody.
Obama's speech, by turns somber and hopeful, at times took on the tone of an exuberant pep rally as he heralded the men who wrestled the gunman to the ground, the woman who grabbed the shooter's ammunition, the doctors and nurses who treated the wounded, the intern who rushed to Giffords' aid. The crowd erupted in multiple standing ovations as each was singled out for praise.
Memories of the six people killed dominated much of Obama's speech.
Obama, for example, recalled how federal Judge John M. Roll was on his way from attending Mass when he stopped to say hello to Giffords and was gunned down; Dorothy Morris, shielded by her husband, but killed nonetheless; and Phyllis Schneck, a Republican who took a shine to Giffords and wanted to know her better.
He spoke at length of 9-year-old Christina Taylor Green, the only girl on her Little League team, who often said she wanted to be the first woman to play in the major leagues. She had just been elected to the student council at her elementary school and had an emerging interest in public service.
"I want us to live up to her expectations. I want our democracy to be as good as she imagined it," Obama said. The little girl was born on Sept. 11, 2001, and had been featured in a book about 50 babies born that day. The inscriptions near her photo spoke of wishes for a happy child's life, including splashing in puddles.
Said Obama: "If there are rain puddles in heaven, Christina is jumping in them today."
As finger-pointing emerged in Washington and beyond over whether harsh political rhetoric played a role in creating motivation for the attack, Obama sought to calm the passions.
"Bad things happen," he said, "and we must guard against simple explanations in the aftermath."
He spoke of decency and goodness, declaring: "The forces that divide us are not as strong as those that unite us."
In addition to the crowd in the arena, thousands more listened from an overflow area in the football stadium.
About a mile away, at University Medical Center, Giffords lay fighting for her life. Other victims also remained there hospitalized.
Back on Capitol Hill, Giffords' House colleagues praised her and the other shooting victims and insisted that violence would not silence democracy.
