存在與本質之先後 The Precedence of Existence and Essence

顯然，東西必須存在，我們才可能分析它的色、聲、香、味、觸等本質。所以，存在先於本質[1]。	Obviously, there must be a thing, so that we can analyze its kinds of essence, such as its form, sound, smell, taste or touch. Therefore, existence precedes essence.
但是，東西必須發出色、聲、香、味、觸等本質，我們才可能發現它的存在。所以，本質先於存在。	However, a thing must give off some kinds of essence, such as its form, sound, smell, taste or touch, so that we can discover its existence. Therefore, essence precedes existence.
綜上所述，存在若且唯若本質。	In summary, existence if only if essence.
