Cultural historian: Universal acceptance of scientific theories that regard human beings only as natural objects subject to natural forces outside the individual' s control will inevitably lead to a general decline in morality. After all, if people do not believe that they are responsible for their actions, they will feel unashamed when they act immorally, and a widespread failure of individuals to feel ashamed of their immoral actions is bound to lead to a general moral decline.

B: Human beings who regard themselves only as natural objects will as a result lose their sense of responsibility for their actions.
C: Some scientific theories hold that human beings are not responsible for their actions.
