Synthesized answer
The passages do not provide specific evidence in the form of examples, data, or detailed arguments from the book. Instead, they summarize the author's overall framework: Smith develops the doctrine of the impartial spectator, argues that we naturally pursue self-interest, and claims that society is held together by sympathy [1]. The passages state that Smith believes we share the emotions and physical sensations of others, and that this leads us to maximize their pleasures and minimize their pains [1].
