What problems does Hardin see in appealing to conscience as a solution?

Garrett Hardin critiques the appeal to conscience as a solution to social and environmental issues by arguing that it relies on individual moral responsibility rather than systemic change. He believes that this approach can lead to inaction, as it places the burden of responsibility on individuals rather than addressing the underlying structural problems. Additionally, Hardin suggests that conscience is subjective and varies among individuals, leading to inconsistent and unreliable outcomes in collective action. Thus, he emphasizes the need for more robust, systemic solutions rather than relying solely on moral appeals.
