Summary
"Public opinion is a second conscience" implies that the collective views and judgements of society act as a moral compass, guiding individuals towards what is considered right or wrong. Just as one's own conscience can shape personal ethical choices, public opinion serves as a larger cultural force that influences behavior, values, and decision-making. This quote suggests that individuals may be compelled to align or conform with the prevalent opinions of society, amplifying the impact of public sentiment on the collective moral fabric of a community or nation.
