He always knew that he would be delivering a speech like this. He just thought, or hoped, that it would be more than four years from now. Yet while it was not technically a farewell address, with six months still to go in office and more presidenting to do, it was the beginning of Joe Biden’s long goodbye.

Mr. Biden’s address to the nation from the Oval Office on Wednesday night was all Joe, love him or hate him — the paeans to American exceptionalism, the evocations of family, the selective boasting about his record, the favorite lofty phrases about an “inflection point” and “saving our democracy,” and yes, the soft, raspy old man’s voice that no longer commands the room the way it once did.

What there was not much of was introspection about how he had gotten to this moment of indignity. He may be focused on the soul of America, but he revealed little of his own. Indeed, if there has been much soul searching over these past days and weeks of personal and political trauma that led to this reluctant end of his storied half-century political career, the search has been called off. Or at least the results were not reported.

He said it was time to “pass the torch to a new generation,” but said nothing about his own age, health or capacity that led so many Democrats to desert him since the calamitous debate on June 27. He did not describe the journey from supreme confidence that he and he alone could beat former President Donald J. Trump to the conclusion that in fact he could not. He offered no elaboration on how he had finally decided to give up his bid for a second term, but at the same time, he held back any bitterness he may have felt.

Instead, it was an opportunity for a reset, to tell his story again on his own terms and recast the narrative as he starts to exit the stage. In his first extended public comments since dropping out, he tried to remind voters who had grown weary or wary of him why most of them had liked him in the first place and maybe, just maybe, to begin to shape his place in history.
