Reality's Structure
- The structure of information in the world and body confirms an external reality.
- Sensory input shapes the brain, demonstrating an interaction with a structured external world.
Embrace Diversity
- Expose yourself to diverse sensory experiences; novelty is costly but rewarding.
- Human brains thrive on diversity, yet we struggle with it socially.
Constructed Emotions
- Emotions are constructed, not triggered: the brain creates them from experiences, not pre-wired circuits.
- This construction explains the variability of emotional responses.

How Emotions Are Made
The Secret Life of the Brain
Lisa Feldman Barrett
In this book, Lisa Feldman Barrett presents a new neuroscientific explanation of emotions, overturning the widely held belief that emotions are automatic, universal, and hardwired in different brain regions.
Instead, she argues that emotions are constructed in the moment through a unique interplay of brain, body, and culture.
Barrett's theory, known as the 'Theory of Constructed Emotions,' suggests that emotions are highly individualized and vary by culture.
The book explores how this new understanding has significant implications for fields such as psychology, medicine, law, parenting, and national security.
Barrett uses clear, readable prose and practical examples to make her complex theories accessible to a broad audience.

The Dragons of Eden
Speculations on the Evolution of Human Intelligence

Sapiens
A Brief History of Humankind

It divides human history into four major parts: the Cognitive Revolution, the Agricultural Revolution, the Unification of Humankind, and the Scientific Revolution.
Harari argues that Homo sapiens dominate the world due to their unique ability to cooperate in large numbers through beliefs in imagined realities such as gods, nations, money, and human rights.
The book also examines the impact of human activities on the global ecosystem and speculates on the future of humanity, including the potential for genetic engineering and non-organic life.

The botany of desire
a plant's eye view of the world
Michael Pollan
In 'The Botany of Desire,' Michael Pollan examines how people and domesticated plants have formed a mutually beneficial relationship.

Pollan illustrates how these plants have evolved to meet human needs and how, in turn, humans have helped these plants spread and thrive.
The book delves into the history and impact of these plants on human society, highlighting the complex and often reciprocal nature of the relationship between humans and plants.
