This volume aims to provide the elements for a systematic exploration of certain fundamental notions of Peirce and Husserl in respect with foundations of science by means of drawing a parallelism between their works. Tackling a largely understudied comparison between these two contemporary philosophers, the authors highlight the significant similarities in some of their fundamental ideas. This volume consists of eleven chapters under four parts. The first part concerns methodologies and main principles of the two philosophers. An introductory chapter outlines central historical and systematical themes arising out of the recent scholarship on Peirce and Husserl. The second part is on logic, its Chapters dedicated to the topics from Peirce’s Existential Graphs and the philosophy of notation to Husserl’s notions of pure logic and transcendental logic. The third part includes contributions on philosophy of mathematics. Chapters in the final part deal with the theory of cognition, consciousness and intentionality. The closing chapter provides an extended glossary of central terms of Peirce’s theory of phaneroscopy, explaining them from the viewpoint of the theory of cognition.

This book invites readers to embark on a journey into the world of agency encompassing humans, other organisms, cells, intracellular molecular agents, colonies, populations, ecological systems, and artificial autonomous systems. We combine mechanistic and non-mechanistic approaches in the analysis of the function and evolution of organisms, their subagents, and multi-organism systems, and in this way offer a theoretical platform for integrating biosemiotics with both natural science and the humanities/social sciences. Agents are autonomous systems that incorporate knowledge on how to make sense of their environment and use it to achieve their goals. The functions of all agents are supported by mechanisms at the lowest level; however, the explanatory power of mechanistic analysis is not sufficient for complex agents. Non-mechanistic methods rely on the goal-directedness of agents whose dynamics follow self-stabilized dynamic attractors. The properties of attractors depend on stable or slowly changing factors, and such dependencies can be interpreted as sign relations if they are adaptive in nature. Agents can replace or redirect mechanisms on demand in order to preserve their functions; for performing higher-level semiotic functions, mechanisms are thus only means. We assume that mechanism and semiosis are not mutually exclusive, and that simple agents can interpret signs mechanistically. This assumption allows us to extend semiotic analysis to all agents, including ribosomes in cells, computers, and robots. This book challenges established traditions in natural science and the humanities/social sciences: semiotics no longer appears as restricted to humans and rational thinking, and biology is no longer limited to rely exclusively on mechanistic reasoning.

All knowledge is always a matter of change, as this book underlines. All knowledge links You and Me to Reality. This process of positioning cognition has become heavily influenced by conversion. Its cultural background is in this book named ‘the New Plural’: a worldview based on combinations of Analog, Digital, AI and Quantum understandings of reality. The New Plural, combined with in-depth observations on the Subject in new forms of knowledge formation, forms the background theme of the book. To understand the Subject as defined in past centuries, like Kant’s so-called ‘split ego’ or Voegelin’s ‘flow’, are outlined together with Husserl’s ‘phenomenology of ego-positions’. Today, one encounters the Subject transformed into a Self with other forms that replace the traditional Subject and its position. The dynamics of the Self are therefore broader than any Selfie can picture. What the book calls ‘the Self in digital culture’ and for what it introduces the name Self-E, is therefore essential for a semiotic observation of all actual patterns and practices of communication. The decentering of the Subject changed human cognition. The book introduces ‘The 3-S Triad’ (composed of the ‘Subject–Self–Self-E’), which has taken the place and functions of the classical Subject and its dynamics. Cognition has assumed a different position in the heart and mind of every human being. At the same time, the influence of ‘The New Plural’ has grown, making digital thought formation the leading pattern and foundation of today’s knowledge. That different view on human identity made knowledge as understanding and its traditional grasping disappear. All fragments of planetary life were subjected to a newly conceived and often digitally anchored fitting. That forms one of the most powerful and global challenges to the human mind. What if we conclude about climate change that our knowledge fits the problems concerned? The book’s final pages outline an epistemological path through such complex zones of knowledge! But its broad and encompassing background question remains, what the concept of change really means when it is challenged to clarify the topic we name climate change.

In three comprehensive volumes, Logic of the Future presents a full panorama of Charles S. Peirce’s most important late writings. Among the most influential American thinkers, Peirce took his existential graphs to be a significant contribution to human thought. The manuscripts from 1895–1913, with many of them being published here for the first time, testify to the richness and open-endedness of his theory of logic and its applications. They also invite us to reconsider our ordinary conceptions of reasoning as well as the conventional stories concerning the evolution of modern logic. This first volume of Logic of the Future is on the historical development, theory and application of Peirce’s graphical method and diagrammatic reasoning. It also illustrates the abundant further developments and applications Peirce envisaged existential graphs to have on the analysis of mathematics, language, meaning and mind.

This second volume collects Peirce’s writings on existential graphs related to his Lowell Lectures of 1903, the annus mirabilis of his that became decisive in the development of the mature theory of the graphical method of logic.

This first part of the third volume (Volume 3/1) of the Logic of the Future series contains Peirce's 1904–1909 writings on his mature philosophy of pragmaticism, which is grounded upon the principles of logical analysis as provided by existential graphs.
