For Mill, when calculating the utility of any particular action, we must include the happiness it will produce for

A. The family of the individual who will perform the action
B. All sentient creatures
C. The indivvidual who will perform the action
D. All human beings

D? What does your book say?

To determine the correct answer, we need to understand the perspective of John Stuart Mill, a philosopher and proponent of utilitarianism. Utilitarianism is an ethical theory that suggests the right action is the one that produces the greatest amount of happiness or well-being for the greatest number of people.

According to Mill, when calculating the utility of any particular action, we should consider the happiness it will produce for all sentient creatures. Sentient creatures are beings capable of experiencing pleasure or pain. This includes not just human beings but also animals who are capable of feeling happiness or suffering.

Therefore, the correct answer is B. All sentient creatures. Mill advocated for a broader consideration of happiness beyond just oneself or a particular group, emphasizing the importance of promoting overall well-being for all beings capable of experiencing pleasure or pain.
