Final answer:
The quote from the speech uses logos as a literary tool by logically arguing for the inclusion of women in the democratic process of voting, aligning with the founding principles of the nation.
Step-by-step explanation:
In the quote from the speech "A woman's right to suffrage," the literary tool being used is logos. Logos appeals to logic and reason by presenting factual and logical arguments to make a point. The speaker in this case is pointing out the contradictions in logic behind denying women the vote when the nation was founded on the principle of liberty for all; this was an essential part of the push for women's suffrage. The emphasis on 'we, the whole people' highlights the illogical exclusion of women from the democratic process, making a strong logical appeal for voter participation rights for women.
