本文嘗試根據康德所界定的對家之構成問題，整理維根其時坦前後期思想所提出的兩套構成理論。文中指出，前期理論所設定的獨我論先然主艘，在後期理論中如何被社會性的主體所取代。維根斯坦提出了“生活形式\"之概念，作為這種社會性主體相互了解的基礎。文曲進一步發展這個概念，�主調生活形式乃是人的生命活動的基本模式。到了這一步，康德式傳統討論構成問題的唯心論傾向，顯然已經開始向一種以實踐為參考。點的唯物主義轉化。

In this article Wittgenstein's philosophy is given a Kantian reading by elaborating the early and late phases of his development as two distinct theories of the constitution of objects_ Itis shown that whereas the early theory presupposes a solipsistic transcendental subject， in the later theory this is replaced by people sharing specific common practices_ Wittgenstein suggested "forms of life" to account for the possibility of understanding within each practice_ But it was Peter Winch who developed this notion further， claiming that they represent modes of human life from which human activities derive their coint"_With the concept of life emerging on the horizon， the problem of constitution as conceived by Kant could shed its traditional idealist shackle and be pursued from a more materialist premise instead.
