The Busyness-Idleness Conundrum

Julien Dupre 1880

In his Works of Love, arguably his greatest ethical text, Kierkegaard uses an agricultural metaphor to describe busyness:

''…the busy people sow and harvest and again sow and harvest (busyness harvests over and over again), […] the busy people store the barns full of what they harvested and rest upon their gains—alas, […] the person who truly wills the good in the same span of time does not see even the smallest fruit of his labors and he becomes the object of ridicule as someone who does not know how to sow, as someone who labors in vain and is merely shadowboxing…''

This passage can be read in light of Kierkegaard’s account of boredom. Like the bored person who rotates their crops, the busy person is described by way of an agricultural metaphor: sowing and harvesting and sowing again. And the bored person and busy person’s similarities do not stop there. The busy person is also experiencing something indeterminate, and is, like the bored person, worse off for doing so.

For Kierkegaard, busy people are experiencing something indeterminate because their activities are not directed towards some particular good. The busy person may seem busy with some specific activity. In the case of the agricultural example in the passage above, the busy person appears busy with sowing and harvesting. The busy person sows and harvests and rests upon these gains. But what is the purpose of this rest? Only to begin once more, for “busyness harvests over and over again.” There is nothing gained by the cycle other than rest from the labor it requires.

Read it all here.

Is there value in idleness? From a psychological standpoint there is, if the idle time is used for reflection. Yet this too is a kind of labor. Further, reflection often leads to productivity and fruition of something latent. For some, physical labor in a field stimulates personal reflection. I know this was true for me while cutting and staking tobacco in Kentucky. 

It appears that we have a conundrum. What are your thoughts on this?

George Ellis "Science and Religion" on The Mind

Randy Isaac of the American Scientific Affiliation reviews

Top-Down Causation in the Human Context
by George Ellis. Berlin Heidelberg: Springer-Verlag, 2016.
501 pages. Hardcover; $80.00. ISBN: 9783662498071

In this magnum opus, as Philip Clayton described it, George Ellis lays out the case for top-down causation in the emergentist perspective. For decades he has been one of the leading proponents of emergence, a philosophical perspective that lies in between strong reductionism on one hand, and vitalism on the other. Reductionist critics of emergence had claimed that the properties and substances that emerged from more fundamental elements had no causal power of their own but were solely determined. Ellis powerfully argues that these emerging entities do indeed have top-down causal powers and that any understanding of the mind, consciousness, and free will must take that into account.

George F R Ellis was born in Johannesburg, South Africa, in 1939. He earned a BS degree in physics from the University of Cape Town and a PhD in Applied Math and Theoretical Physics at Cambridge University. He collaborated with Stephen Hawking to co-author the book The Large Scale Structure of Space-Time. He returned to the University of Cape Town in 1973 where he taught until retirement in 2005, becoming one of the world’s leading theorists in cosmology. He is a Quaker and has served as president of the International Society for Science and Religion. He was awarded the Templeton Prize in 2004. He is a co-author with Nancey Murphy of the book On The Moral Nature of the Universe: Cosmology, Theology, and Ethics. Ellis is a Platonist and has long worked on the emergence of complexity and top-down causality, the focus of this book.

The Stanford Encyclopedia of Philosophy characterizes emergence as “emergent entities (properties or substances) ‘arise’ out of more fundamental entities and yet are ‘novel’ or ‘irreducible’ with respect to them.” Reductionists have countered that these emergent entities have no real causal powers but are determined by the fundamental entities in a purely bottom-up fashion. Ellis devotes this book to showing how top-down causation by the emergent entities on the fundamental entities is real and not illusory. He credits many colleagues for work over several decades in compiling this resource, including Nancey Murphy, Warren Brown, Tim O’Connor, Robert Russell, and others.

Emergence is context dependent, Ellis points out. In the natural world, self-assembly is the key mechanism of emergence. In the biological world it is natural selection while in the man-made world emergence is found in design and construction. His focus is not so much on origins to explain how the world came to be as it is on describing the way the world is. An interacting ensemble of entities, no matter how they came together, generates new entities with more complexity. Ellis offers us a compendium of all the ways in which this can happen.

At the publisher’s request, Ellis structured the book in such a way that each chapter could be sold as a separate stand-alone booklet in addition to the entire set of eight chapters as a single book. This style led to a significant amount of repetition, especially of references, but in a sense, that repetition helped provide an illusion of actually understanding the material. A brief description of each chapter will help the reader decide which option is best for them.

Chapter 1: Complexity and Emergence

Ellis introduces all the key terms and ideas in the first chapter, though with few examples and a minimum of detail. He sets forth the basic ideas of the hieracrchical structure of the universe and of emergence of causal entities at the higher levels. He ends the chapter with some practical implications for health care, mental health, and education. The chapter therefore serves as an effective complete summary of the book but will leave the reader seeking a more detailed explanation.

Complexity lies in the hierarchical structure, in which the bottom layers are the fundamental forces and particles of physics and chemistry. The higher levels are composed of combinations and interactions of the entities in the lower levels. Ensembles of large numbers of interacting entities at one level enable new entities at the next higher level. Those higher-level entities can, in turn, have a causal effect on the lower level entities by controlling the scope and bounds of their interaction. These higher-level entities are said to emerge from that interaction. Bottom-up causation refers to the lower levels of physical particles and their interactions generating higher level, more complex entities. Top-down causation refers to the higher levels imposing constraints or boundary conditions on the lower level entities.

Reductionists claim that top-down causation is an illusion and everthing is determined in a bottom-up fashion. Vitalists, and, in a sense, spiritualists, posit a vital or spiritual force that provide the top-down causation to the lower level entities. Emergentists claim that the top-down causation of higher level entities is real, necessary, and sufficient for the joint top-down/bottom-up causal effects to explain the structure of the universe. Ellis ignores the vitalists and addresses this book as a response to reductionists.

Chapter 2: Digital Computer Systems

Anyone who, like me, has participated in the design of a computer hardware system or who has written any software program will greatly enjoy this chapter. Ellis describes the hardware and software as hierarchical systems that display all the key features of emergence. A reader unfamiliar with and uninterested in computing systems can safely skip this chapter but it does provide an illuminating description of the major features of emergence.

Most, though not necessarily all, higher-levels entities in computing systems are created by intelligent designers and do not emerge through self-organization of the lower levels or through natural selection. In other words, the higher levels of the hierarchy that impose constraints on the lower levels are constructed by intelligent agents external to the computing system itself. A circuit designer, for example, can direct a computer processor chip manufacturer to constrain the size and shape of a transistor. The atoms and molecules in that transistor then interact within the confines of that top-down constraint and effect the behavior desired by the designer. Emergence refers to the properties and entities that arise when the designer has implemented the desired constraints and context.

Ellis closes this chapter with this gem: “At a higher level, the existence of computers is an outcome of the human drive for meaning and purpose: it is an expression of the possibility space of meanings, the higher levels whereby we guide what actions take place.”

Chapter 3: The Basis of Complexity

Chapters 3 and 4 lay out the technical details of emergence. In this chapter the focus is on the hierarchical structure that forms the basis for complexity. Moving from a lower level to a higher level in the hierarchy, the components of one level are comprised of ensembles of interacting elements of the next lower level. For example, solid materials are composed of a very large number of atoms which occupy a lower level in the hierarchy. These atoms, in turn, are composed of protons, neutrons, and electrons which comprise an even lower level. Looking upwards, the solid material forms the basis, when shaped or combined with other solids, of an object that can be used as a tool. The tool may result from an even higher level of intent or purpose to carry out a particular function. The shape of that tool forms a basis for the range of motion of the component atoms. In this way, both top-down and bottom-up causation can be seen.

Chapter 4: Types of Top-Down Causation

The second part of the technical explanation of emergence emphasizes the many different ways in which top-down causation can occur. The simplest types are deterministic as in the lower levels where, say, quarks interact to form protons and neutrons with little variation. More complex types occur in higher level systems where feedback can occur. At even higher levels there are much more interesting types involving adaptive systems. When a high level entity can change in such a way that the lowest levels are channeled into enabling a modified higher level system, then adaptation has occurred. This is where the tremendous power of emergence can be seen.

Chapter 5: Is There Room at the Bottom?

Ellis asks whether the notion of bottom-up and top-down working simultaneously would overdetermine the system. If the physics of the lowest levels is causally closed, can top-down causation really occur? Here Ellis provides several ways in which top-down causation can work. There can be contextual constraints or constraining structures or a change in the nature of the lower level elements. An example of the last is that a free neutron has a lifetime of less than 15 minutes but when the neutron forms a higher level nucleon by interacting with one or more protons or other neutrons, it is stable. The interaction of the neutron with other particles changes the nature of the neutron. Causality from above influences the outcomes of the lower-level causal forces.

Chapter 6: The Foundations: Physics and Top-Down Causation

Physicists and chemists as well as astronomers and cosmologists will revel in reading this chapter. Ellis dives into the details of the lower levels of the hierarchies in this universe to examine the fundamental forces. He explores quantum dynamics, the arrow of time, and gives numerous examples from condensed-matter physics and chemistry. The principles of emergence as laid out in the previous chapters are beautifully illustrated by many examples. Those who are not enamored with physics or chemistry can safely skip or skim the chapter.

Chapter 7: The Mind and the Brain

At last Ellis arrives at the issue everyone is waiting for. How can the brain give rise to the mind? No one should miss this chapter. Not only are biologists and neuroscientists in prominence but also those broadly involved in the social context of our world.

In the hierarchical perspective, a brain is enabled from the bottom by a series of levels from the fundamental particles up through the biochemistry of life and the neurons and neural networks. In turn, these networks in the brain enable a higher level of individual consciousness which in turn enables a society of interacting individuals forming a culture. All of this occurs in the context of an environment leading to a fine-tuned system.

The high level social interactions and environment affect personal perceptions, ideas, and purpose, leading to decisions and actions that causally work downward to direct biochemical activity. Such activity enables the desired actions. In this way, bottom-up and top-down causality work together to implement what we call the mind.

The importance of adaptive systems is emphasized in this chapter. Biological systems are far more adaptive than non-biological systems. When higher level entities are able to modify selection criteria and adapt to the environment by influencing the outcomes of the lower level processes, then a vast spectrum of possibilities opens up.

Chapter 8: The Broader View

Ellis refers to this portion of the book as a polemic that sets emergence apart from reductionism. He reprises the full concept of emergence and then looks at the broad implications.

Inserted in this chapter is a section on “Learning to Read and Write” that Ellis co-authors with his wife, Carole Bloch. They argue that modern methods of teaching people to read over-emphasize a bottom-up approach. This means that there is a focus on the elemental phonemes before putting it all together into a meaningful sentence. Rather, they recommend a greater emphasis on top-down learning in which the meaning is emphasized first. Then the combination of top-down and bottom-up learning leads to a more efficient process. This exemplifies Ellis’ view that everything can be treated as an integrated bottom-up/top-down system.

The book suffers from the weight of making each chapter a stand-alone booklet. The flow is uneven and repetitive. The benefit is that each chapter can indeed be read by itself and a reader interested in only one aspect of emergence can profitably select the relevant chapter. The reader will then be left hungry for more and will want to return for the remaining chapters.

Ellis does not allude to the implications for science and faith. He is a man of faith and has written elsewhere of his disagreement with atheism and with those who advocate a scientific religion. His views seem to be essentially that of Non-Interventionist Objective Divine Action (NIODA) as advocated by Robert Russell, Nancey Murphy, and others. The emergence that he describes in this book is easily compatible with such a view. Multi-level explanations lend themselves well to including the spiritual domain, as Donald MacKay, for example, explained in the middle of the 20th century. On the other hand, materialists can also find support for their own presupposition in this book. The higher levels of explanation, including those leading to meaning and purpose, are fully enabled by the underlying physics and need no external source. If spiritual levels are not required, though not negated, by a complete hierarchical explanation of a system, then on what basis do we believe they exist? Most of all, this book strikes at the heart of dualism. The mind is described as enabled by the brain through the emergence of entities capable of supporting consciousness and rational thought through the interaction of a vast number of complex neurological components. It cannot exist independently from the brain and needs no external vitality other than the environmental interaction for food and energy. The concepts in this book will fuel discussions on faith and science for a long time to come.

Ellis closes the book with this final paragraph: “The daily world in which we live came about by imaginative investigation of possibilities, discarding those that don’t work: the adaptive process that is a central theme of this book, enabled by a modicum of randomness at the macro- and micro-levels, interacting with necessary physical processes. And it is these processes that also allow the emergence of the ordinariness of everyday life: which actually is quite extraordinary. Bottom-up effects are crucial to emergence. Physics underlies all. Nevertheless, the vitality of life, which arises from physics, transcends it.”

The casual reader seeking a relaxing fireside read is advised to look elsewhere. This book is an indispensable resource for anyone who seriously ponders the structure of the universe, the miracle of life, and the mystery of consciousness.
