How does Booker see his lack of identity in the early years?

Booker sees his lack of identity as an effect of slavery. The institution itself removed all sense of identity except for the stories passed down from one generation to the next. Booker sees his maternal family as victims. He also sees his father, rumored to be a white man, as a victim of the institution of slavery.

Of my ancestry I know almost nothing. In the slave quarters, and even later, I heard whispered conversations among the coloured people of the tortures which the slaves, including, no doubt, my ancestors on my mother's side, suffered in the middle passage of the slave ship while being conveyed from Africa to America. I have been unsuccessful in securing any information that would throw any accurate light upon the history of my family beyond my mother. She, I remember, had a half-brother and a half-sister. In the days of slavery not very much attention was given to family history and family records - that is, black family records. My mother, I suppose, attracted the attention of a purchaser who was afterward my owner and hers. Her addition to the slave family attracted about as much attention as the purchase of a new horse or cow. Of my father I know even less than of my mother. I do not even know his name. I have heard reports to the effect that he was a white man who lived on one of the near-by plantations. Whoever he was, I never heard of his taking the least interest in me or providing in any way for my rearing. But I do not find especial fault with him. He was simply another unfortunate victim of the institution which the Nation unhappily had engrafted upon it at that time.
