Josephus was little more than thirty years old at the time of his surrender. At an age when men usually begin to realize their ambition and ideal, his whole life's course was changed: he had to abandon all his old associations, and accommodate himself to a different and indeed a hostile society. Henceforth he was a liege of the Roman conqueror, and had to submit to be Romanized not only in name but in spirit. His condition was indeed a thinly-disguised servitude. The Romans were an imperious as well as an Imperial people, and though in some circumstances they were ready to spare the lives of those who yielded, they required of them a surrender of opinion and an abasement of soul. For the rest of his years, which comprehended the whole of his literary activity, Josephus was not therefore a free man. He acted, spoke, and wrote to order, compelled, whenever called upon, to do the will of his masters. His legal condition was first that of a _libertus_ (a freedman) of Vespasian, and as such he owed by law certain definite obligations to his patron's family. But the moral subservience of the favored prisoner of a subjugated people must have been a far profounder thing than the legal obligation arising from his status; and this enforced moral and mental subservience is a cardinal point to be remembered in forming a judgment upon Josephus. His expressed opinions are often not the revelation of his own mind, but the galling tribute which he was compelled to pay for his life. And apart from the involuntary and undeliberate adoption of Roman standards, which, living isolated from Jewish life in Rome, he could not escape, he had in writing, and no doubt in conversation, deliberately and consciously to assume the deepest-seated of the Roman prejudices towards his own people. Liberty has been defined as the power of a man to call his soul his own. And in that sense Josephus emphatically did not possess liberty. We must be on our guard, therefore, against regarding him as an independent historian, much less as writing from an independent Jewish point of view. From the time of his surrender till his death he lived and wrote as the client of the Flavian house, and all his works had to pass the Imperial censorship.
