《第一哲学沉思集》中出现的“阿尔诺循环”体现了笛卡尔的认识论立场和本体论立场的冲突。“我思故我在”作为哲学体系的起点,说明认识论立场的优先性,而关于“上帝存在”的本体论问题的探讨则使得“理性/感性”对立的传统得以延续。理性相对于感性的优先性使得审美活动在理性主义的体系中一直不能得到重视。 The “Arnold cycle” appearing in “The First Philosophical Contemplation” embodies Descartes’ clashes between epistemological and ontological positions. As the starting point of the philosophical system, “I think and therefore I am” indicates the priority of epistemological position, while the discussion on the ontological issue of “God ’s existence makes the tradition of ” rational / sensual "contradictory continued. The priority of reason relative to sensibility makes the aesthetic activity unworthy of importance in the system of rationalism.
