    有的学者还指出,要坚持集体主义还必须将集体主义的价值精神与社会主义市场经济的要求结合起来,批判地继承计划经济时代倡导的集体主义,合理地对其进行体系结构的调整和内容的更新,形成新的集体主义。与传统的集体主义相比,这种新的集体主义应具有如下两个主要特点。其一,强调集体的出发点是为了维护集体成员的正当个人利益。传统的集体主义具有片面强调集体至上性、绝对性的弊端;新的集体主义必须依据社会主义市场经济的现实要求,将集体应当对个人承担的义务加以科学的阐释。真正的集体应该维护各个集体成员的个人利益,实现组成集体的各个主体的自我价值。这种新型的集体主义是对社会主义市场经济条件下社会关系的真实反映,既与个人主义有本质区别,也不同于传统的集体主义。其二,要体现道德要求的先进性与广泛性的统一。

    人教版高中政治必修4第二课百舸争流的思想教案

    不可知论是否认人们认识世界或彻底改造世界的可能性的哲学学说。此概念首先由英国的赫胥黎(1825—1895)于1869年提出,不可知论的思想在古代就已产生,欧洲近代的主要代表是休谟和康德。其本质是把人的感觉看作是主观和客观之间的屏障而不是桥梁,不承认在感觉之外有确实可靠的客观外部世界的存在,不懂得认识过程中本质与现象、有限与无限的辩证关系。对不可知论最有力的驳斥是实践。有时不可知论一词也用以专指针对宗教教义而提出的一种学说,认为上帝是否存在、灵魂是否不朽是不可知的。2.二元论二元论是认为世界有两个本原的哲学学说,与一元论相对立,它把物质和意识绝对对立起来,认为物质和意识是两个各自独立、相互平行发展着的实体,谁也不产生谁,谁也不决定谁,都是世界的本原。它的观点是错误的:它肯定精神不依赖于物质而独立存在,这本身就是唯心主义的观点;它虽然承认物质是独立的本原,但在说明物质和精神的关系时,又把精神说成是唯一具有能动性的力量,必然倒向唯心主义。主要代表人物是法国的笛卡儿和德国的康德。
