Final answer:
The logical fallacy in the Declaration of Sentiments is a hasty generalization.
Step-by-step explanation:
The logical fallacy in the Declaration of Sentiments is a hasty generalization. A hasty generalization is a faulty logic where not enough evidence is used to draw a reliable conclusion. In the Declaration of Sentiments, the statement 'The history of mankind is a history of repeated injuries and usurpations on the part of man toward woman, having in direct object the establishment of an absolute tyranny over her' generalizes the entire history of mankind as being characterized by the mistreatment of women, without providing sufficient evidence to support this claim.
