不久前,数学领域中开展了一場尖銳的思想斗爭,这个斗爭集中表現在对数学发展道路的两种不同观点、两条不同道路的斗爭上。在这次斗爭中,主观唯心主义的論点(理論——理論——理論)遭到了彻底的破产,从而捍卫了辯証唯物主义的真理(实践——理論——再实践)。斗爭取得了伟大的胜利,大大地提高了数学工作者的辯証唯物主义的思想水平。但是,这还不是說主观唯心主义的影响完全肃清了,在数学领域中,这一影响还比較广泛地不同程度地存在着。孙泽瀛先生編的“解析几何学”一书的緒言中,就較为明显地表現了主观唯心主义的有害的观点。据了解,有的学校已經采用这本书作为教学用书了,因此,有必要在 Not long ago, there was a sharp ideological struggle in the field of mathematics. This struggle was concentrated on two different perspectives on the road to mathematics development and on two different roads. In this struggle, the subjective idealism argument (theory-theory-theory) was completely bankrupted, thus defending the truth of dialectical materialism (practice-theory-re-practice). The struggle has achieved a great victory and greatly improved the mathematical worker’s dialectical materialism. However, this is not to say that the influence of subjective idealism has been completely eliminated. In the field of mathematics, this influence still exists more widely and to varying degrees. In the introductory book “Analytic Geometry” edited by Mr. Sun Zeyi, the harmful views of subjective idealism are more clearly expressed. It is understood that some schools have already adopted this book as a teaching book. Therefore, it is necessary to
