近代性主義大師斯賓諾莎，以其堅持真理、淡泊寧靜、企向永恆之域的高貴靈魂，在眾多西洋哲學家中，特別為中國哲學院所讚賞。其代表作《倫理學》，為一具獨創性而閎深的形上學兼人生哲學之巨著。而如此類的內容，竟以幾何學式的方法和形式之(例如：先作定義，續述公則，繼之提出定理而由演繹推論以證明之)，尤讓現代的讀者覺得新奇。其中所陳述的諸定義乃是一種實質定義，亦即賦予某某名號以形式本質內容，代表了其特定的哲學或知識立場，可謂其哲學最濃縮精簡的表象或其整體哲學玄思的焦點眼目。本文即針對其第一章〈論神〉之八個定義範疇，一一作闡釋，試圖釐清其中可能的疑點而解決之，且除系統內的考察外，並嘗試系統外的比較批評。

Spinoza is a Rationalist philosophers who has long been admired and respected by Chinese scholars and philosophers due to his tranquil personality and his perseverance in searching for reality. Is most famous work, Ethics, formulates one of the most consummate systems of metaphysics in philosophy and has also been recognized as philosophy of life. Many contemporary readers are fascinated by the geographic representations in Ethics (e.g., definitions are given first, followed by axiom, propositions, and then deductive conclusions), which gave both meanings and forms to the essence of philosophy. The eight definitions of God in Ethics represent his philosophical and epistemological stance, and it is those definitions of God that I would like to discuss in this paper. I will try to clarity several problematic issues regarding the definitions. I will also provide criticism and comparison of viewpoints between Spinoza and others.
