C.S. Lewis on Suffering and What It Means to Have Free Will in a Universe of Fixed Laws

By:

“Try to exclude the possibility of suffering which the order of nature and the existence of free wills involve, and you find that you have excluded life itself.”

If the universe operates by fixed physical laws, what does it mean for us to have free will? That’s what C.S. Lewis considers with an elegant sidewise gleam in an essay titled “Divine Omnipotence” from his altogether fascinating 1940 book The Problem of Pain (public library) — a scintillating examination of the concept of free will in a material universe and why suffering is not only a natural but an essential part of the human experience. Though explored through the lens of the contradictions and impossibilities of belief, the questions Lewis raises touch on elements of philosophy, politics, psychology, cosmology, and ethics — areas that have profound, direct impact on how we live our lives, day to day.

He begins by framing “the problem of pain, in its simplest form” — the paradoxical idea that if we were to believe in a higher power, we would, on the one hand, have to believe that “God” wants all creatures to be happy and, being almighty, can make that wish manifest; on the other hand, we’d have to acknowledge that all creatures are not happy, which renders that god lacking in “either goodness, or power, or both.”

To be sure, Lewis’s own journey of spirituality was a convoluted one — he was raised in a religious family, became an atheist at fifteen, then slowly returned to Christianity under the influence of his friend and Oxford colleague J.R.R. Tolkien. But whatever his religious bent, Lewis possessed the rare gift of being able to examine his own beliefs critically and, in the process, to offer layered, timeless insight on eternal inquiries into spirituality and the material universe that resonate even with those of us who fall on the nonreligious end of the spectrum and side with Carl Sagan on matters of spirituality.

Lewis writes:

There is no reason to suppose that self-consciousness, the recognition of a creature by itself as a “self,” can exist except in contrast with an “other,” a something which is not the self. . . . The freedom of a creature must mean freedom to choose: and choice implies the existence of things to choose between. A creature with no environment would have no choices to make: so that freedom, like self-consciousness (if they are not, indeed, the same thing), again demands the presence to the self of something other than the self.

What makes Lewis’s reflections so enduring and widely resonant is that, for all his concern with divinity, he cracks open the innermost kernel of our basic humanity, in relation to ourselves and to one another:

People often talk as if nothing were easier than for two naked minds to “meet” or become aware of each other. But I see no possibility of their doing so except in a common medium which forms their “external world” or environment. Even our vague attempt to imagine such a meeting between disembodied spirits usually slips in surreptitiously the idea of, at least, a common space and common time, to give the co- in co-existence a meaning: and space and time are already an environment. But more than this is required. If your thoughts and passions were directly present to me, like my own, without any mark of externality or otherness, how should I distinguish them from mine? And what thoughts or passions could we begin to have without objects to think and feel about? Nay, could I even begin to have the conception of “external” and “other” unless I had experience of an “external world”?

In a sentiment that calls to mind novelist Iris Murdoch’s beautiful definition of love (“Love is the very difficult understanding that something other than yourself is real.”), Lewis adds:

The result is that most people remain ignorant of the existence of both. We may therefore suppose that if human souls affected one another directly and immaterially, it would be a rare triumph of faith and insight for any one of them to believe in the existence of the others.

Lewis considers what it would take for us to fully acknowledge and contact each other’s otherness, to bridge the divide between the internal and the external:

What we need for human society is exactly what we have — a neutral something, neither you nor I, which we can both manipulate so as to make signs to each other. I can talk to you because we can both set up sound-waves in the common air between us. Matter, which keeps souls apart, also brings them together. It enables each of us to have an “outside” as well as an “inside,” so that what are acts of will and thought for you are noises and glances for me; you are enabled not only to be, but to appear: and hence I have the pleasure of making your acquaintance.

Society, then, implies a common field or “world” in which its members meet.

'Tree of virtues' by Lambert of Saint-Omer, ca. 1250, from 'The Book of Trees.' Click image for details.

That “neutral something” might sound a lot like faith, but Lewis is careful to point out the limitations of such traditional interpretations and to examine how this relates to the question of suffering:

If matter is to serve as a neutral field it must have a fixed nature of its own. If a “world” or material system had only a single inhabitant it might conform at every moment to his wishes — “trees for his sake would crowd into a shade.” But if you were introduced into a world which thus varied at my every whim, you would be quite unable to act in it and would thus lose the exercise of your free will. Nor is it clear that you could make your presence known to me — all the matter by which you attempted to make signs to me being already in my control and therefore not capable of being manipulated by you.

Again, if matter has a fixed nature and obeys constant laws, not all states of matter will be equally agreeable to the wishes of a given soul, nor all equally beneficial for that particular aggregate of matter which he calls his body. If fire comforts that body at a certain distance, it will destroy it when the distance is reduced. Hence, even in a perfect world, the necessity for those danger signals which the pain-fibres in our nerves are apparently designed to transmit. Does this mean an inevitable element of evil (in the form of pain) in any possible world? I think not: for while it may be true that the least sin is an incalculable evil, the evil of pain depends on degree, and pains below a certain intensity are not feared or resented at all. No one minds the process “warm — beautifully hot — too hot — it stings” which warns him to withdraw his hand from exposure to the fire: and, if I may trust my own feeling, a slight aching in the legs as we climb into bed after a good day’s walking is, in fact, pleasurable.

Yet again, if the fixed nature of matter prevents it from being always, and in all its dispositions, equally agreeable even to a single soul, much less is it possible for the matter of the universe at any moment to be distributed so that it is equally convenient and pleasurable to each member of a society. If a man traveling in one direction is having a journey down hill, a man going in the opposite direction must be going up hill. If even a pebble lies where I want it to lie, it cannot, except by a coincidence, be where you want it to lie. And this is very far from being an evil: on the contrary, it furnishes occasion for all those acts of courtesy, respect, and unselfishness by which love and good humor and modesty express themselves. But it certainly leaves the way open to a great evil, that of competition and hostility. And if souls are free, they cannot be prevented from dealing with the problem by competition instead of courtesy. And once they have advanced to actual hostility, they can then exploit the fixed nature of matter to hurt one another. The permanent nature of wood which enables us to use it as a beam also enables us to use it for hitting our neighbor on the head. The permanent nature of matter in general means that when human beings fight, the victory ordinarily goes to those who have superior weapons, skill, and numbers, even if their cause is unjust.

But looking closer at the possible “abuses of free will,” Lewis considers how the fixed nature of physical laws presents a problem for the religious notion of miracles — something he’d come to examine in depth several years later in the book Miracles, and something MIT’s Alan Lightman would come to echo several decades later in his spectacular meditation on science and spirituality. Lewis writes:

Such a world would be one in which wrong actions were impossible, and in which, therefore, freedom of the will would be void; nay, if the principle were carried out to its logical conclusion, evil thoughts would be impossible, for the cerebral matter which we use in thinking would refuse its task when we attempted to frame them. All matter in the neighborhood of a wicked man would be liable to undergo unpredictable alterations. That God can and does, on occasions, modify the behavior of matter and produce what we call miracles, is part of Christian faith; but the very conception of a common, and therefore stable, world, demands that these occasions should be extremely rare.

He offers an illustrative example:

In a game of chess you can make certain arbitrary concessions to your opponent, which stand to the ordinary rules of the game as miracles stand to the laws of nature. You can deprive yourself of a castle, or allow the other man sometimes to take back a move made inadvertently. But if you conceded everything that at any moment happened to suit him — if all his moves were revocable and if all your pieces disappeared whenever their position on the board was not to his liking — then you could not have a game at all. So it is with the life of souls in a world: fixed laws, consequences unfolding by causal necessity, the whole natural order, are at once limits within which their common life is confined and also the sole condition under which any such life is possible. Try to exclude the possibility of suffering which the order of nature and the existence of free wills involve, and you find that you have excluded life itself.

He closes by bringing us full-circle to the concept of free will:

Whatever human freedom means, Divine freedom cannot mean indeterminacy between alternatives and choice of one of them. Perfect goodness can never debate about the end to be attained, and perfect wisdom cannot debate about the means most suited to achieve it.

The Problem of Pain is a pause-giving read in its entirety. Complement it with Lewis on duty, the secret of happiness, and writing “for children” and the key to authenticity in all writing, then revisit Jane Goodall on science and spirituality.

The Book of Trees: 800 Years of Visualizing Science, Religion, and Knowledge in Symbolic Diagrams

By:

How the humble tree became our most powerful visual metaphor for organizing information and distilling our understanding of the world.

Why is it that when we behold the oldest living trees in the world, primeval awe runs down our spine? We are entwined with trees in an elemental embrace, both biological and symbolic, depending on them for the very air we breathe as well as for our deepest metaphors, millennia in the making. They permeate our mythology and our understanding of evolution. They enchant our greatest poets and rivet our greatest scientists. Even our language reflects that relationship — it’s an idea that has taken “root” in nearly every “branch” of knowledge.

How and why this came to be is what designer and information visualization scholar Manuel Lima explores in The Book of Trees: Visualizing Branches of Knowledge (public library) — a magnificent 800-year history of the tree diagram, from Descartes to data visualization, medieval manuscripts to modern information design, and the follow-up to Lima’s excellent Visual Complexity: Mapping Patterns of Information.

'Genealogical distribution of the arts and sciences' by Chrétien Frederic Guillaume Roth from Encyclopédie (1780)

A remarkable tree featured as a foldout frontispiece in a later 1780 edition of the French Encyclopédie by Denis Diderot and Jean le Rond d'Alembert, first published in 1751. The book was a bastion of the French Enlightenment and one of the largest encyclopedias produced at that time. This tree depicts the genealogical structure of knowledge, with its three prominent branches following the classification set forth by Francis Bacon in 'The Advancement of Learning' in 1605: memory and history (left), reason and philosophy (center), and imagination and poetry (right). The tree bears fruit in the form of roundels of varying sizes, representing the domains of science known to man and featured in the encyclopedia.

'Notabilia' by Mortiz Stefaner, Dario Taraborelli, and Giovanni Luca Ciampaglia (2011)

A visualization of the 100 longest online discussions on Wikipedia articles up for deletion, part of the collaborative editing process that defines the encyclopedia of our time. These discussions last for at least seven days, until consensus is reached on which of a series of proposed actions (such as keep, merge, rename, or delete) should be performed on a page. Starting from a common root, this visualization maps each of the 100 articles as an individual branch, with color segments and shape determined by the sequence of 'keep' (green) and 'delete' (purple) votes. The final arch of each branch indicates the voting results, bending toward either left (keep) or to the right (delete).

'Tree of virtues' by Lambert of Saint-Omer, ca. 1250

Palm tree illustration from the 'Liber floridus (Book of flowers),' one of the oldest, most beautiful, and best-known encyclopedias of the Middle Ages. Compiled between the years 1090 and 1120 by Lambert, a canon of the Church of Our Lady in Saint-Omer, the work gathers extracts from 192 different texts and manuscripts to portray a universal history or chronological record of the most significant events up to the year 1119. This mystical palm tree, also known as the 'palm of the church,' depicts a set of virtues (fronds) sprouting from a central bulb. The palm tree was a popular early Christian motif, rich in moral and symbolic associations, often used to represent the heavens or paradise.

'Plan of Organization of New York and Erie Railroad' by Daniel Craig McCallum (1855)

Diagram viewed by economists as one of the first organizational charts. The plan represents the division of administrative duties and the number and class of employees engaged in each department of the New York and Erie Railroad. Developed by the railroad's manager, the engineer Daniel Craig McCallum, and his associates, the scheme features a total of 4,715 employees distributed among its five main branches (operating divisions) and remaining boughs (passenger and freight departments). At the roots of the imposing tree, in a circular layout, are the president and the board of directors.

Lima writes in the introduction:

In a time when more than half of the world’s population live in cities, surrounded on a daily basis by asphalt, cement, iron, and glass, it’s hard to conceive of a time when trees were of immense and tangible significance to our existence. But for thousands and thousands of years, trees have provided us with not only shelter, protection, and food, but also seemingly limitless resources for medicine, fire, energy, weaponry, tool building, and construction. It’s only normal that human beings, observing their intricate branching schemas and the seasonal withering and revival of their foliage, would see trees as powerful images of growth, decay, and resurrection. In fact, trees have had such an immense significance to humans that there’s hardly any culture that hasn’t invested them with lofty symbolism and, in many cases, with celestial and religious power. The veneration of trees, known as dendrolatry, is tied to ideas of fertility, immortality, and rebirth and often is expressed by the axis mundi (world axis), world tree, or arbor vitae (tree of life). These motifs, common in mythology and folklore from around the globe, have held cultural and religious significance for social groups throughout history — and indeed still do.

[...]

The omnipresence of these symbols reveals an inherently human connection and fascination with trees that traverse time and space and go well beyond religious devotion. This fascination has seized philosophers, scientists, and artists, who were drawn equally by the tree’s inscrutabilities and its raw, forthright, and resilient beauty. Trees have a remarkably evocative and expressive quality that makes them conducive to all types of depiction. They are easily drawn by children and beginning painters, but they also have been the main subjects of renowned artists throughout the ages.

'The Tree of Life' by Gustav Klimt (1901), one of the most reproduced oil paintings in human history

Among the legions of artists captivated by trees was the great Leonardo da Vinci. Shortly before his death, in one of his voluminous notebooks, Da Vinci worked out a mathematical formula for the relationship between the size of a tree’s trunk and that of its branches — he found that as a tree grows, the total cross-sectional area of all new branches is roughly equal to the area of the mother trunk or branch, no matter the height of the tree. Centuries later, scientific tests using computer-generated models of trees have not only found Leonardo’s formula to hold up across nearly every tree species, but also to explain trees’ remarkable resilience to wind and other external forces.

'Tree Branching' by Leonardo da Vinci (ca. 1515)

Study of a tree branching. Leonardo's rule is fairly simple, stating that 'Every year when the boughs of a tree have made an end of maturing their growth, they will have made, when put together, a thickness equal to that of the main stem.'

Indeed, Leonardo’s formula touched on the very thing that makes the tree such a powerful metaphor for organizing knowledge — its natural function not merely as a static object, but also as a system of relational dynamics. Lima writes:

Our primordial, symbolic relationship with the tree can elucidate why its branched schema has provided not only an important iconographic motif for art and religion, but also an important metaphor for knowledge-classification systems. Throughout human history the tree structure has been used to explain almost every facet of life: from consanguinity ties to cardinal virtues, systems of laws to domains of science, biological association to database systems. It has been such a successful model for graphically displaying relationships because it pragmatically expresses the materialization of multiplicity (represented by its succession of boughs, branches, twigs, and leaves) out of unity (its central foundational trunk, which is in turn connected to a common root, source, or origin.)

Anonymous, 'Yggdrasil tree' (ca. 1680)

A depiction of the world tree or cosmic ash tree, from an Icelandic manuscript containing several illustrations from Norse mythology. Yggdrasil is drawn surrounded by various animals, which live in and on it. Of particular relevance is Ratatoskr, a green squirrel on the bottom left, who, according to Norse mythology, runs up and down Yggdrasil to carry messages between the eagle, shown at the top, and the dragon, Niohöggr, who gnaws at the roots.

Kabbalistic tree of life from 'Oedipus AEgyptiaus' (1652)

Illustration by the Jesuit scholar and polymath Athanasius Kircher. Kabbalah is a Jewish mystical tradition; the term translates as 'received,' in reference to teachings passed through generations or directly from God. A pivotal element of the Kabbalah wisdom is the tree of life, an image composed of a diagram of ten circles, symbolizing ten pulses, or emanations, of divine energy.

'Vortices' by René Descartes, from Principia Philosophiae (1644)

A model of the universe that was widely accepted in the 17th century, based on the Cartesian system of vortices: large whirlpools of tenuous or ethereal matter that were thought to move the planets and their satellites by contact.

'Voronoi treemap' by Michael Balzer, (2005)

A pioneering alternative to conventional rectangular treemaps that relied on Voronoi tessellation to map hierarchies. In contrast to layout algorithms based on rectangular subdivisions, the Voronoi treemap layout algorithm was the first to generate flexible polygonal subdivisions, eliminating analogous shapes and aspect ratios, while also producing extremely alluring organic layouts.

I was delighted to see a longtime favorite among the selections — Stefanie Posavec’s brilliant Writing Without Words project, a hand-drawn visualization of the “literary organism” in Jack Kerouac’s novel On the Road, depicting the sentences, words, and rhythm structures in the book.

'Writing Without Words' by Stefanie Posavec, (2008)

The Book of Trees is a treasure trove of visual literacy, symbolic history, and cultural insight. Complement it with this visual history of tree diagrams explaining evolution and these glorious drawings of trees from Indian mythology, then revisit Rachel Sussman’s gorgeous photographs of Earth’s oldest living trees.

Alan Watts on the Difference Between Belief and Faith

By:

How to master the delicate dance of unconditional openness to the truth.

A century and a half before Carl Sagan explored the relationship between science and religion, Ada Lovelace, the world’s first computer programmer, contemplated the subject in a beautiful letter. Two centuries later, Alan Lightman crafted an enchanting definition of secular spirituality. This question has also been addressed by Albert Einstein in answering a little girl’s question about whether scientists pray, Flannery O’Connor in considering dogma, belief, and the difference between religion and faith, and Jane Goodall in her exquisite conversation with Bill Moyers on science and spirituality — and yet the question is, and perhaps is bound to remain, an open one.

One of the most articulate and lucid attempts to answer it comes from Alan Watts, who popularized Eastern philosophy in the West, in his fantastic 1951 book The Wisdom of Insecurity: A Message for an Age of Anxiety (public library) — the same treasure trove of insight that gave us Watts on happiness and how to live a full life and his prescient admonition about our modern media gluttony.

Watts writes:

We must here make a clear distinction between belief and faith, because, in general practice, belief has come to mean a state of mind which is almost the opposite of faith. Belief, as I use the word here, is the insistence that the truth is what one would “lief” or wish it to be. The believer will open his mind to the truth on the condition that it fits in with his preconceived ideas and wishes. Faith, on the other hand, is an unreserved opening of the mind to the truth, whatever it may turn out to be. Faith has no preconceptions; it is a plunge into the unknown. Belief clings, but faith lets go. In this sense of the word, faith is the essential virtue of science, and likewise of any religion that is not self-deception.

[…]

The present phase of human thought and history … almost compels us to face reality with open minds, and you can only know God through an open mind just as you can only see the sky through a clear window. You will not see the sky if you have covered the glass with blue paint.

But “religious” people who resist the scraping of the paint from the glass, who regard the scientific attitude with fear and mistrust, and confuse faith with clinging to certain ideas, are curiously ignorant of laws of the spiritual life which they might find in their own traditional records. A careful study of comparative religion and spiritual philosophy reveals that abandonment of belief, of any clinging to a future life for one’s own, and of any attempt to escape from finitude and mortality, is a regular and normal stage in the way of the spirit. Indeed, this is actually such a “first principle” of the spiritual life that it should have been obvious from the beginning, and it seems, after all, surprising that learned theologians should adopt anything but a cooperative attitude towards the critical philosophy of science.

The Wisdom of Insecurity is the kind of book that stays with you for life. Complement it with Watts on money vs. wealth and your ego, the universe, and becoming who you really are.
