Final answer:
Phillip is using his moral imagination to make his decision, considering the ethical implications for the workers' wellbeing in the hot Arizona summer.
Step-by-step explanation:
Phillip is relying on e. his moral imagination to make his decision. Moral imagination involves envisioning the full range of possibilities in a situation, considering the ethical dimensions and impacts of those possibilities, and seeking a course of action that is in line with one's ethical principles. In Phillip's case, he is considering the wellbeing of the workers alongside the goals of the project, a reflection of his concern for ethical treatment as opposed to merely operational or economic efficiency. This situational evaluation aligns with modern discussions in moral philosophy, which often critique or build upon the earlier works of thinkers like Anscombe, Ross, and Baxter, all of whom offered perspectives on the complexities of moral decisions beyond simple ethical rules or absolutes.
