INSIGHT

Enlightenment Tilted Culture Toward Mechanism

The Enlightenment shifted Western culture toward a left-hemisphere, mechanistic view that prizes manipulation and explicit logic.
Ian McGilchrist argues this created blind spots by neglecting relational, imaginative, and contextual knowing.

ANECDOTE

The Toll Of Writing A Big Book

McGilchrist nearly killed himself writing The Matter With Things, driven by a 'demon' to keep writing without much rest.
He described the project as enormous and warned about obsessive overwork even for meaningful projects.

INSIGHT

Two Hemispheres, Two Worlds

Each brain hemisphere produces a different experiential world and attention style, with the right hemisphere offering broader perception and wiser judgments.
McGilchrist contends the left alone is delusional and best limited to narrow tasks like routine manipulation.

Montaillou

Cathars and Catholics in a French Village, 1294-1324

Emmanuel Le Roy Ladurie

This book by Emmanuel Le Roy Ladurie examines the lives and beliefs of the population of Montaillou, a small village in the Pyrenees, at the beginning of the fourteenth century. It is largely based on the Fournier Register, a set of records from the Inquisition that investigated and attempted to suppress the spread of Catharism in the Ariège region. The work provides a detailed picture of peasant society, including their social structures, sexual practices, religious beliefs, and daily lives. It is a landmark in the genre of microhistory and offers insights into the mentalité of the villagers, their attitudes towards time, space, magic, morality, death, and childhood.

The Matter with Things

Our Brains, Our Delusions, and the Unmaking of the World

Iain Mcgilchrist

In 'The Matter with Things', Iain McGilchrist delves into the neuroscience, epistemology, and metaphysics of the brain's hemispheres and their impact on human perception and understanding. The book is divided into two volumes: 'The Ways to Truth' and 'What Then is True? '. McGilchrist argues that the left hemisphere's dominance has led to a skewed perception of the world, neglecting the vital role of the right hemisphere in integrating science, reason, intuition, and imagination. He explores topics such as attention, perception, judgement, and the nature of reality, including concepts like time, space, consciousness, and the sacred. The book is a call to re-enchant the world and ourselves by recognizing the deeper, more holistic understanding provided by the right hemisphere.

The Waning of the Middle Ages

Also known as The Autumn of the Middle Ages or Autumntide of the Middle Ages

Johan Huizinga

In this book, Huizinga presents a detailed portrait of life in the fourteenth and fifteenth centuries, focusing on the conventions and customs that reflect the 'autumnal waning' of the Middle Ages. He examines various aspects such as the violent tenor of medieval life, chivalry, courtly love, religious life, and the symbolism that pervaded medieval society. Huizinga argues that the period was marked by cultural exhaustion, pessimism, and nostalgia, rather than the dawn of the Renaissance. The book is based on extensive examples from documents, literature, and artwork of the time and provides insights into the medieval mindset as the Middle Ages transitioned into the Renaissance.

The master and his emissary

The Divided Brain and the Making of the Western World

Iain McGilchrist

This book argues that the division of the brain into two hemispheres is essential to human existence, allowing for two incompatible versions of the world. The left hemisphere is detail-oriented, prefers mechanisms to living things, and is inclined to self-interest, while the right hemisphere has greater breadth, flexibility, and generosity. McGilchrist takes the reader on a journey through the history of Western culture, illustrating the tension between these two worlds as revealed in the thought and belief of thinkers and artists from ancient to modern times. He argues that the increasing dominance of the left hemisphere in today’s world has potentially disastrous consequences.

Dominion

The Power of Man, the Suffering of Animals, and the Call to Mercy

Matthew Scully

In 'Dominion,' Matthew Scully presents a comprehensive and eloquent case against the mistreatment of animals. The book delves into various aspects of animal suffering, including factory farming, hunting, whaling, and laboratory experiments. Scully challenges the notion that humans have unlimited dominion over animals, as suggested by biblical interpretations, and argues for a moral and compassionate approach to animal treatment. He draws on both religious and scientific perspectives to make his case, emphasizing the importance of empathy and the recognition of animal consciousness and suffering. The book is a call to action for reform and a plea for human benevolence and mercy towards animals.

Dr. Ian McGilchrist, best known for his books “The Matter with Things” (2021) and “The Master and His Emissary” (2009), is a psychiatrist, philosopher, and neuroscientist well known around the world. He comes on today, not only to take the (in)famous Light-O-Meter test, but also to talk about reality, about how we relate to reality, and the old vs new schools of thought.

--- This “Enlightened” New World utopia isn’t turning out to be all it was cracked up to be. Society is disenchanting, but are the only alternatives hiding out in the hills or burying yourself in books? With an air of levity and a touch of humor, John Heers teaches how to examine the confusing New World by calling upon the mind and wisdom of oft-forgotten Old. Heavy Things, Lightly. ---
