The sentence in this excerpt from Susan B. Anthony's "On Women's Right to Vote" that reveals the purpose of the speech is:
"It shall be my work this evening to prove to you that in thus voting, I not only committed no crime, but, instead, simply exercised my citizen's rights, guaranteed to me and all United States citizens by the National Constitution, beyond the power of any state to deny."
After being tried and fined for casting an "illegal" vote in the presidential elections of 1872, Susan B. Anthony gave this speech to prove that, according to the preamble of the Federal Constitution women had the same right to vote as men.
She explained that the Constitution says "we, the people" which includes not only america's man, but also its women. Therefore, her casting a ballot was not only not illegal, but it was a right that no state should have the power to deny.
