笛卡爾在《第一哲學沉思》中嘗試的現代形而上學"新計劃",突破了早年的方法路徑,通過"一次性"的形而上學懷疑及其取消,在一個不可經驗的認識原點上,為新科學及其認識原理提供了新的基礎。

The “new plan” of modern metaphysics attempted by Descartes in Meditations on First Philosophy surmounted difficulties in the methodological path he had pursued in his early years. Through the metaphysical doubt“once and for all”and its negation,it provides a new foundation for the new sciences and their cognitive principles on an inexperienceable cognitive point.
