Educated, by Tara Westover
(Edited)

I retrieved my journal and wrote another entry, opposite the first, in which I revised the memory.
p. 196.8

revised = changed what was said
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.

revision = making changes

Definitions:

(1) (revise)
to change (and hopefully improve) -- most frequently to improve a written document, but it can be any intentional change such as a change in an estimated amount, a plan, or a series of procedures
(2) (meaning too rare to warrant focus)
In the UK, revise can also mean to review material previously studied to prepare for a test.
