在对已有关于信息本质及定义的理论学说进行批判性剖析的基础上 ,从“存在”这一哲学本体论范畴角度 ,对信息本质及定义作了新的思考与界定:文章突破了哲学界关于“存在形态”的传统理论 ,提出了将“存在”分为“实在”、“虚在”、“虚实在及实虚在”的新观点 ;并将信息界定在只存在于以生命体为主体方的关系中的“虚实在及实虚在”范畴中 ,认为信息是只对生命体有意义的“虚实在及实虚在”。形象而简单地说 ,信息是游荡于实在与虚在之间的“精灵”。 Based on the critical analysis of the existing theory about the nature and definition of information, from the philosophical ontology category of “Being”, this paper makes a new thinking and definition of the nature and definition of information: With regard to the traditional theory of “existential forms”, this paper puts forward a new viewpoint that divides “existence” into “reality”, “virtual reality”, “virtual reality” and “virtual reality” In the category of “virtual reality and virtual reality” in the relationship of the main party, information is regarded as the “virtual reality and the actual virtual reality” that is meaningful only to the living body. To put it succinctly, information is an “elven” who wanders between reality and reality.
