福利權在本質上涉及了使用他人，涉及了使用某一部分人的財產和勞動成果來掖助另一部分人，因此，除非證成了某些對於他人的使用的正當性，否則福利權將無法被合理化。本文旨在討論福利權該如何被合理化，就論述的展開路徑來說，本文先行分析諾吉克 (R.  Nozick) 所堅持的不得使用他人的規範，在理論上及實踐上所暴露的侷限。隨後本文又對於福利權所涉及的使用他人的類型進行釐清，並以「所有的人都能自由的平等權利｣ 爲基核，來證成福利權。最後則探討福利權如何能協助透顯「社羣｣ 的具體影像。

Welfare rights and using others are intrinsically connected. Yet, some theorists, among whom Robert Nozick is the most typical, stoutly deny the legitimacy of using others in political reasoning. This article contends that political life by its very nature cannot completely exclude use of others, and by further classifying different kinds of using others, tries to justify the legitimacy of a certain kind of using others, that is life­-sustaining use of others. The basic belief behind the justification is that misfortune as a human condition should not be casted away unreflec­tively for the sake of the inviolability of self-ownership. In discussing the foundation of welfare rights, the author also argues that welfare rights can be taken as a concrete way of visualizing the desirability of com­munity, which occupies a core place in contemporary debate in political philosophy.
