For example, similar principles apply to U.S. foreign policy, which aims to keep the country safe, secure access to foreign markets, and protect human rights. These goals collectively contribute to a successful foreign policy strategy. Likewise, in the context of a philosophical or ethical approach, acknowledging the force that permeates the universe, the natural flow of all things, and a path which people ought to follow might be collectively important. Moreover, when discussing reforms, such as in the area of bio understanding, ensuring the narrative is entrenched in people's mindsets is crucial. Each component supports the overall success of the initiative or policy.
