The meaning of the "ground" is clear but I have problem with the phrase below:
In knowing the ground was not ground at all.
So, could you please what the meaning of the phrase is?
The full text is hear:
“I am Professor Steinberg,” he said. “What would you like to read?” I mumbled something about historiography. I had decided to study not history, but historians. I suppose my interest came from the sense of groundlessness I’d felt since learning about the Holocaust and the civil rights movement—since realizing that what a person knows about the past is limited, and will always be limited, to what they are told by others. I knew what it was to have a misconception corrected—a misconception of such magnitude that shifting it shifted the world. Now I needed to understand how the great gatekeepers of history had come to terms with their own ignorance and partiality. I thought if I could accept that what they had written was not absolute but was the result of a biased process of conversation and revision, maybe I could reconcile myself with the fact that the history most people agreed upon was not the history I had been taught. Dad could be wrong, and the great historians Carlyle and Macaulay and Trevelyan could be wrong, but from the ashes of their dispute I could construct a world to live in. In knowing the ground was not ground at all, I hoped I could stand on it.
