回顾信息概念的研究和探索历程,信息最著名的概念经历了从最初的熵和负熵的理论,到之后的差异说、形式说和状态说,从类反映说到意义和符号,再到计算信息和量子信息的学说,等等。虽然在这些理论中可以不同程度地看到客观信息的影子,但是只有中国信息哲学中的“间接存在”概念将客观信息世界予以了最清晰的揭示。早在40多年前,中国信息哲学就指出:“信息是标志间接存在的哲学范畴,它是物质(直接存在)存在方式和状态的自身显示。”后来,中国信息哲学又根据自己提出的信息形态分类理论,把“认识和实践主体对信息的主观把握和创造”也明确地纳入到关于信息本质的扩展性规定之中。近年来,中国信息哲学的最新发展,把存在、非存在,演化和时间,物质、信息和意识等纳入了信息哲学研究的统一框架,进而增加了对信息本质探讨的“物质世界与非存在世界的指向者”的新维度。由于在存在论层面揭示了信息的本质,中国信息哲学提出的间接存在论学说对人类哲学作出了全方位的独创贡献。
