which excerpt in the passage best demonstrates hope for the future?

voices from the veil
by w. e.b. du bois (adapted excerpt)

i believe in liberty for all men: the space to stretch their arms and their souls, the right to breathe and the right to vote, the freedom to choose
their friends, enjoy the sunshine, and ride on the railroads, thinking, dreaming working as they will in a kingdom of beauty and love. i believe in
the training of children; the leading out of little souls into the green pastures and beside the still waters, not for pelf or peace, but for felt by
some large vision of beauty and goodness and truth; lest we forget, and the sons of the fathers like esau, for mere meat barter their birthright
in a mighty nation. finally, i believe in patience-patience with the weakness of the weak and the strength of the strong, the prejudice of the
ignorant and the ignorance of the unseeing patience with the tardy triumph of joy and the mad chastening of sorrow.
