Read the final five lines of the poem: "how they knew what we/ must know/ without knowing a page/ of it/ themselves." what is the author suggesting?

I think that this means, that
How they knew what we
Must know
Without knowing a page did so for future generations to raise them
Of it
Themselves. above themselves/ knew that economic independence would help all women

The author is suggesting that how did they know what we must know with out knowing a page of ? it themselves. So some group of people needed to know something ( probably a book) and somebody knew what they needed to know without knowing a page of (a book probably) something without knowing even a page of it ( possibly a book, that has what the original group of people must know) them selves. Plz 5 star, give thank and brainliest answer. 

Send me the exerpt and i will read it.
