In the most general if unconventional terms, science is the study of how man is part of the universe. Philosophy is the study of man’s ideas of the universe and how man differs from the rest of the universe. It has of course been recognized that philosophy and science are not totally disjointed. Science is in any case not a monolithic entity but refers to knowledge as the results of reasoning and both invasive and non-invasive experiment. We argue that the philosophy of science, in studying the foundations, methods and implications of science and the link between philosophy and science, must now take into account the impact of the rapidly developing science and philosophy of information. We suggest that the philosophy of information is in fact a metaphilosophy, since informational processes operate in all the sciences and their philosophies. The simplest definition of (a) metaphilosophy is that of a set of statements about (a) philosophy, and any definition of a metaphilosophy thus requires one of philosophy and of the task of philosophy as well. According to Sellars, “the aim of philosophy is to understand how things in the broadest possible sense of the term hang together in the broadest possible sense of the term”. In this paper, we focus on the recursive thought underlying those statements as real processes, occurring both in and between the fundamental and the meta-level. We propose a non-standard logic, Logic in Reality, as the logic of those processes. The metaphilosophy of information is thus a framework for talking about the scientific aspects of philosophy and the philosophical aspects of science. Both Logic in Reality and the metaphilosophy of information provide a basis for understanding the physical and epistemological dynamics of existence, that is, from where the properties of things come that enable both them and the concepts of them to contrast, conflict and ultimately “hang together”. We conclude that the current convergence of science and philosophy under the influence of information science constitutes a revolution in philosophy, that is, in how science and philosophy are done. Many of the issues discussed in the metaphilosophy of information may thus be viewed as part of an emerging informational metaphilosophy of science.

I define information from a philosophical perspective as a category that indicates the presence of indirect existence, which is a self-display by material entities (with direct existence) of the status and trajectory of that existence. In this paper, based in part on articles published only in Chinese over the last 30 years, information is shown to include three basic forms: In-itself, for-itself and regenerated information, which is constituted by the first two. Information in these three basic forms establishes the essence of information which is further developed in a fourth form—social information. Information is further characterized by the qualities of its three different grades, corresponding to these forms: The quality of first-grade information demonstrates direct objective existence and indirect objective existence; the quality of second-grade information demonstrates multiple levels of direct objective and indirect objective existence; the quality of third-grade information is that of the subjective relationships in human understanding that are encoded as information. The grounding of information in the ontological structure of the world gives it a central role in the approach to knowledge, constituting a new and necessary critique of the classical separation of the academic disciplines and the bases of modern philosophy.

Under the impact of information technology and the information sciences, major changes are occurring in both science and philosophy that constitute an informational turn. The recently developed Philosophy of Information has integrated the unique dualistic ontological properties of information, and scientific rationality can now be seen to include an interactive relationship between science and philosophy. Information, in particular Information Science is thus part of the structure, and not just of the content, of philosophy. In this mode of knowledge development, science transforms philosophy and philosophy can critique both science and itself. I see a process of convergence taking place that is leading to a Unified Science-Philosophy of Information, a system of disciplines of which the Philosophy of Information is a part, and Information Science achieves an additional dimension based on this fundamental philosophical stance. I argue further that a proper new Philosophy of Science would be an informational metaphilosophy in that a Unified Science-Philosophy of Information includes both a new content of Science and new dynamics of the relations between a science and its philosophy.

The interpretation of entropy and negative entropy theories on the nature of information is the first scientific paradigm on the interpretation of the nature of information at the beginning of the rise of contemporary information science. The information entropy or negative entropy theories are the relative measurement for the structuralization degree of the system at a specific level, which have certain characteristics of relativity, functionality, and quantification. Although the concepts of entropy, negative entropy, information, entropy increase, and entropy decrease often have very different specific meanings in different disciplines and for different scientists, the meanings of these concepts are unified in essence and the differences between them are generated when the same kind of concepts is applied to the study of different directions of the same kind of phenomena: either to the static structuralization degree of the system or to the change of the dynamic structuralization degree of the system. Since entropy and negative entropy theories only measure the relationship of structural differences at a specific level of the system from a formal aspect, they are not aimed at the information itself but rather they are aimed at only the structuralization characteristics of the information carrier itself at a specific level. Because of this, it is impossible to deduce the general nature of information directly from such theories.

Through the rescientification of philosophy and the philosophization of science, an entirely new concept of science and philosophy as part of general human knowledge is developing. In this concept, science and philosophy become intrinsically integrated and unified, forming dynamic feedback-loops which lead to further mutual transformation and integration. This development is taking place in the face of two kinds of dogmatism: one is naturalistic dogmatism, the other the dogmatism of consciousness philosophy. These two kinds of dogmatism are an inevitable consequence of the method of segmentation of the field of existence in traditional philosophy namely: existence = matter + Spirit (mind). The development of the Science and Philosophy of Information reveals a world of information-by-itself lying between the worlds of matter and Sprit, and re-interprets the essence of the Spiritual world in the sense of prior information activities. Accordingly, we can describe the movements from matter to Spirit, and from Spirit to matter in these activities as processes, eliminating their dualistic separation, and achieve an informational turn in philosophy, the first truly fundamental one.
