# Background knowledge to deeply understand ‘Homo Deus: A Brief History of Tomorrow’ by Yuval Noah Harari
History of Humankind
To fully grasp the arguments presented in *Homo Deus*, a solid understanding of human history is crucial. Harari’s previous book, *Sapiens: A Brief History of Humankind*, provides a comprehensive overview of this history, covering the cognitive revolution, the agricultural revolution, and the unification of humankind. Understanding these milestones, particularly the transition from hunter-gatherer societies to agricultural societies and the subsequent rise of empires and globalization, is essential for appreciating Harari’s analysis of the forces shaping humanity’s future.
Biological Evolution and the Nature of Humans
*Homo Deus* explores the potential for humans to transcend their biological limitations. Therefore, a basic understanding of biological evolution, including concepts like natural selection and genetic mutation, is helpful. Furthermore, the book delves into the nature of consciousness, emotions, and free will, which are all topics explored in fields like neuroscience and philosophy. Familiarizing oneself with these concepts can enhance one’s comprehension of Harari’s arguments about the possibilities of upgrading human capabilities through biotechnology and artificial intelligence.
Technological Advancements and their Impact
The central theme of *Homo Deus* is the impact of technological advancements on the future of humanity. Readers should have a general understanding of key technological trends, such as artificial intelligence, biotechnology, nanotechnology, and dataism. It is important to grasp the potential implications of these technologies on areas like healthcare, economics, warfare, and social structures. Knowledge of the current state of these technologies and the ethical dilemmas surrounding their development and implementation is crucial for evaluating Harari’s predictions.
Political and Economic Systems
*Homo Deus* touches on the evolution of political and economic systems and how they might be affected by future technological advancements. A basic understanding of different political ideologies (e.g., liberalism, communism, nationalism) and economic systems (e.g., capitalism, socialism) is helpful. Furthermore, knowledge of current global challenges like climate change, inequality, and political instability can provide context for understanding Harari’s discussion of the potential future scenarios for humanity.
Philosophy and Ethics
Harari’s work frequently intersects with philosophical and ethical questions about the meaning of life, the nature of consciousness, and the future of humanity. Familiarizing oneself with different philosophical perspectives, including humanism, transhumanism, and dataism, can deepen one’s understanding of the ethical dilemmas presented by the potential for human enhancement and the rise of artificial intelligence. It’s also beneficial to have some understanding of ethical frameworks for navigating these complex issues, such as utilitarianism, deontology, and virtue ethics.
Religion and Spirituality
While not a central focus, *Homo Deus* touches upon the role of religion and spirituality in human history and their potential future. A basic understanding of the history of major religions and the concepts of secularism and atheism can provide context for understanding Harari’s perspective on the evolving relationship between humans and belief systems in a technologically advanced world.
Dataism and Algorithms
*Homo Deus* introduces the concept of “Dataism,” a new ideology that views the universe as a flow of data and sees algorithms as the key to understanding and controlling this flow. To fully grasp this concept, it is helpful to understand the basics of algorithms, big data, and machine learning. This includes understanding how algorithms are designed, how they are used to analyze data, and the potential implications of increasing reliance on algorithms for decision-making in various aspects of life.
The Concept of Liberal Humanism
Harari argues that liberal humanism, the dominant ideology of the modern era, is facing a potential crisis in the face of technological advancements. Understanding the core tenets of liberal humanism, including individualism, human rights, and the belief in human reason and progress, is essential for evaluating Harari’s claims about its potential decline. It is also helpful to be aware of the criticisms levelled against liberal humanism and its potential shortcomings in addressing the challenges of the 21st century.
By familiarizing oneself with these areas of knowledge, readers can gain a deeper appreciation for the complexities and nuances of Harari’s arguments in *Homo Deus*. This background knowledge allows for a more informed and critical engagement with the book’s exploration of the potential future paths of humanity and the challenges and opportunities that lie ahead.
