The phrase "different purposes" refers to various goals, objectives or intentions that are unique and distinct from one another. It means that different individuals or groups have their own specific reasons for doing something, which may vary depending on their needs, wants, beliefs, values, or circumstances. In other words, people act with different motivations, expectations, and desired outcomes in mind when they engage in activities or make decisions. The phrase highlights the fact that there is no one-size-fits-all solution to any problem, as everyone's perspective and needs are unique.
