The ubiquitous pathways of positive feedback in the human brain are generally held to be a necessary condition for the phenomenon of conscious sensation. However, no dynamic mechanism, no causal link has been established between the physical brain and its mental attributes, our sensations, thoughts, our consciousness. I suggest that the missing link between the world of neurons and that of mind is to be found in the transformations the brain performs on the coordinates of physical space and time. In particular, the convolution of past, present and future, that characterizes subjective sensations, blurs the distinction between cause and effect, and allows the emergence of a self-generated phenomenon of consciousness.

The concept of emergence is widely used in both the philosophy of mind and in cognitive science. In the philosophy of mind it serves to refer to seemingly irreducible phenomena, in cognitive science it is often used to refer to phenomena not explicitly programmed. There is no unique concept of emergence available that serves both purposes.

In this book, Hodgson presents a clear and compelling case against today's orthodox mechanistic view of the brain-mind, and in favor of the view that "the mind matters." In the course of the argument he ranges over such topics as consciousness, informal reasoning, computers, evolution, and quantum indeterminancy and non-locality. Although written from a philosophical viewpoint, the book has important implications for the sciences concerned with the brain-mind problem. At the same time, it is largely non-technical, and thus accessible to the non-specialist reader.

This paper begins by tracing interest in emergence in physics to the work of condensed matter physicist Philip Anderson. It provides a selective introduction to contemporary philosophical approaches to emergence. It surveys two exciting areas of current work that give good reason to re-evaluate our views about emergence in physics. One area focuses on physical systems wherein fundamental theories appear to break down. The other area is the quantum-to-classical transition, where some have claimed that a complete explanation of the behaviors and features of the objects of classical physics entirely in quantum terms is now within our grasp. We suggest that the most useful way to approach the emergent/non-emergent distinction is in epistemic terms, and more specifically that the failure of reductive explanation is constitutive of emergence in physics.

The present study asks the question whether Karl Rahner’s treatment of biological evolution holds merit for the dialogue between Catholic theology on the one hand and evolutionary biology on the other. Central to this evaluation will be an emphasis on two core tenets of modern evolutionary biology, namely emergence and the continuity of the evolutionary process. While the former bears relevance for our understanding of how life and anthropologically important phenomena such as “mind” and “consciousness” came to be, the latter plays a crucial role in how we view our existence within the earth’s fluid and changing biosphere. It comes to the conclusion that Rahner’s concept of active self-transcendence recovers the notion of biological evolution as an on-going process where indeed something new emerges, and therefore offers an extremely helpful tool in the interdisciplinary conversation. However, this essay challenges Rahner’s understanding of the directedness of the evolutionary process toward the human being as well as his view that in us nature comes to self-consciousness for the first time and suggests alternatives.

Emergence, a hot topic of discussion for the last several years, has implications not only for the study of science but also for theology. I survey Philip Clayton's book Mind & Emergence , drawing from it and applying some of its philosophical principles to a theological interpretation of emergence. This theological interpretation is supplemented by a brief examination of relevant biblical usages of the term kenosis. From this exploration of kenosis, I assert that the Spirit is kenotically poured into creation, which onsets the long and laborious process of prebiotic evolution, leading to biological evolution toward increasing complexity. The complexification of matter, then, has its ontological origin in and through the agency of the Spirit of God. As such, the concept of creatio continua , continuing creation, is defended. The Spirit enables emergence by endowing creation and creatures with the ability to unfold by apparent natural processes according to their own inherent potentialities and possibilities. This essay contributes to a systematic theology of creation by constructing a theological synthesis between kenosis and emergence.

Emergence is a notorious philosophical term of art. A variety of theorists have appropriated it for their purposes ever since George Henry Lewes gave it a philosophical sense in his 1875 Problems of Life and Mind. We might roughly characterize the shared meaning thus: emergent entities (properties or substances) ‘arise’ out of more fundamental entities and yet are ‘novel’ or ‘irreducible’ with respect to them. (For example, it is sometimes said that consciousness is an emergent property of the brain.) Each of the quoted terms is slippery in its own right, and their specifications yield the varied notions of emergence that we discuss below. There has been renewed interest in emergence within discussions of the behavior of complex systems and debates over the reconcilability of mental causation, intentionality, or consciousness with physicalism.

This volume introduces readers to emergence theory, outlines the major arguments in its defence, and summarizes the most powerful objections against it. It provides the clearest explication yet of this exciting new theory of science, which challenges the reductionist approach by proposing the continuous emergence of novel phenomena.
