What principle asks if everyone in the world would be expected to act the same way?

The principle that asks if everyone in the world would be expected to act the same way is known as the rule of universality. This concept is rooted in ethical philosophy, particularly in the context of moral reasoning and decision-making. It suggests that for an action to be considered morally right, it should be acceptable for everyone to act in a similar manner in similar circumstances.

The rule of universality encourages individuals to consider the broader implications of their actions beyond personal interest or specific situations. It asks individuals to reflect on the consequences if everyone followed the same course of action, promoting consistency in moral reasoning and discouraging selective ethical standards. By applying this principle, people enhance fairness and equality in their moral judgments.

This concept is distinct from the golden rule, which focuses on treating others as one wishes to be treated, and different from the principle of equality, which emphasizes equal treatment and opportunities for all individuals. Additionally, the law of reciprocity pertains to the idea of mutual exchange in relationships and obligations, rather than examining actions through a universal lens. Thus, the rule of universality serves as a foundational ethical guideline for evaluating behavior on a global scale.
