This page describes my journey as I learned more about the Age of Limits — issues such as climate change, resource depletion, population overshoot and biosphere loss. The page has been divided into four sections:
The Starting Point: A Forest Dark
A History of Knowledge
Predicaments and Oxymorons
The Church’s Opportunity
A summary of each section is provided below. The full document is available here as a .pdf file.
1. The Starting Point: A Forest Dark
My journey to do with understanding the Age of Limits started many years ago when I was a teenager in high school. We were required to read that remarkable novella The Machine Stops by E.M Forster. Although written in the year 1909, the book captures so much of what makes up our current society, including dependence on computers and social media.
My journey then moves on to an article I read in a chemical engineering journal. In the article the author shows how ethanol as a fuel hardly makes sense. Although the author does not use the term ERoEI (Energy Returned on Energy Invested), it is a concept toward which he is moving.
Next we have Rifkin’s book Entropy Into the Greenhouse World. Although published over 30 years ago, this book captures much of what we are learning now about the consequences of climate change. He also explains the reasons behind the deforestation of Europe in the Middle Ages, and the resulting need to use fossil fuels. Finally, he shows how the concept of “progress” has become baked into our way of thinking.

2. A History of Knowledge
The next phase in my journey came from a reading of Charles van Doren’s book A History of Knowledge. Two insights were particularly important. The first was to do with Augustine of Hippo and his book City of God, written around the year 420 CE. Augustine recognized that all “cities of men”, i.e., human organizations, decline and eventually fail. (The fall of the city of Rome in 410 was particularly traumatic for Augustine and other early church fathers.) The only “city” that is permanent, Augustine argued, is the spiritual city — the City of God. Augustine is often seen as being the most important Christian theologian after Paul of Tarsus. I suggest that we now need a theology that is relevant to the crises of our time.
A History of Knowledge was also important to me because it showed how science and technology developed, starting with the Galileo Galilei and his observation of the “heavens”. Galileo declared that heavenly objects such as the moon and planets are made of the same materials as objects here on Earth, and are subject to the same laws of physics.
This line of thought continues with discussion to do with the insights of Francis Bacon, René Descartes and Isaac Newton. Each of them, in his own way, contributed toward the intellectual success of science, and the material success of technology.
The section concludes with a discussion of the book Hard Times, written by Charles Dickens. Like many of his novels, this book describes the impact of the industrial revolution and the miseries that it brought to so many people. He was deeply concerned with what we now refer to as social justice, particularly justice for children. The importance of works such as this is that people communicate by telling stories to one another, yet this approach is rarely used by technical people such as myself, yet we need to recognize that it is the way that most people learn. Dickens was particularly adept at the use of satire.
3. Predicaments and Oxymorons
The issues that we discuss at this site are complex and difficult to understand. Moreover, they interact with one another in ways that are difficult even identify. Moreover, many of the conclusions and action items that we come up will not work in practice. This is why the term “technically feasible” is included in the site’s Mission Statement.
For many years the author John Michael Greer published a blog entitled the Archdruid Report. One of his insights is that we face predicaments, not problems. Problems have solutions, predicaments do not. When faced with a predicament we can respond and adapt, but we cannot make it go away. This thought provides the basis for my second theological point, “Accept and Adapt”.
Next in this section comes the philosopher Georg Hegel and the concept of Hegelian Synthesis. The idea is that we have a “thesis” — an existing condition. It is followed by an “anti-thesis”. It, in turn, is followed by a “synthesis” that incorporates elements of both of the preceding states, but is different from both of them. In the context of this site the thesis is pre-industrial society, the anti-thesis is the industrial society we have created through the use of fossil fuels, and the synthesis is the world that we are in the process of creating.
Jevons Paradox is a very important concept that is discussed in the article Jevons Paradox. In our context, the paradox suggests that efforts we make to “save the environment” will not only fail, they could be counter-productive and could actually make matters worse.
Next up we have the late Dr. Albert Bartlett and his well-known lecture Arithmetic, Population & Energy that explained how the exponential function affects us. Quotations from his talk include, “The greatest shortcoming of the human race is our inability to understand the exponential function”, and, “Sustainable growth is an oxymoron”. Regarding resource and environmental limits, he put these issues in the context of population growth. It is not the absolute quantity of a resource that matters, it is the quantity of that resource per head of population. And if the world’s population is growing exponentially then all our efforts to turn things around are likely to be confounded.
Finally in this section, we have Ugo Bardi and his blog Cassandra’s Legacy. His post The Empire of Lies was particularly helpful to me as I was writing this book. provided a basis for the theological theme, “Understand and tell the truth”.
4. The Church’s Opportunity
The next stage in my learning, a stage that is very much a work in progress, was a realization that we are not going to receive effective leadership from secular institutions. In spite of all the well-researched reports from well-funded organizations such as the IPCC (Intergovernmental Panel on Climate Change) we continue to consume the Earth’s resources without constraint, and we continue to fill the environment with our waste products, particularly CO2, as can be seen from the following chart. Even the COVID-19 pandemic has not changed this trajectory significantly.
As I learned about the predicaments that we face, I also learned that the situation presents an opportunity for people of faith and for the church to provide much-needed leadership. This opportunity is discussed at the Response page.
