马克思主义哲学是关于自然、社会和思维发展规律的一般性科学,是我国高校大学生必修的一门课程。本文试用唯物辩证法的观点从现象与本质、局部与整体、主要矛盾与次要矛盾、规律的特殊性和量变质变规律的普遍性等方面阐述马克思主义哲学原理对外科学的重要指导价值。 Marxist philosophy is a general science on the law of the development of nature, society and thinking, and a compulsory course for university students in our country. This paper attempts to use the viewpoints of materialist dialectics to expound the important guiding value of Marxist philosophy in external science from the aspects of phenomenon and essence, local and whole, primary and secondary contradictions, the particularity of laws and the universality of quantitative and qualitative changes.
