Early Life and Education: Key Philosophers and Scientists

Sam Harris was born on April 9, 1967, in Los Angeles, California. He grew up in a secular household, and his early intellectual influences came from his education and reading. As a student at Stanford University, Harris studied philosophy, which introduced him to the works of key thinkers such as Plato, Aristotle, and Immanuel Kant. These philosophers laid the groundwork for Harris’ understanding of ethics, metaphysics, and epistemology.

Harris’ interest in neuroscience was sparked after a transformative experience with MDMA, leading him to pursue a Ph.D. in the field at the University of California, Los Angeles. During his studies, he was heavily influenced by the work of neuroscientists like V.S. Ramachandran and Francis Crick. Their research on brain function and consciousness provided Harris with a scientific foundation for his later arguments about the nature of the mind and the roots of morality.

The New Atheist Movement: Key Collaborators and Ideas

Harris’ first book, “The End of Faith,” was published in 2004 and catapulted him into the public eye. Its critique of religious dogma and the promotion of secularism resonated with many readers and helped establish Harris as a prominent member of the “New Atheist” movement. This group of thinkers, which included Richard Dawkins, Daniel Dennett, and the late Christopher Hitchens, sought to promote secularism and criticize religion from an intellectual standpoint.

The New Atheist movement’s ideas and discussions significantly influenced Harris’ thinking on religion, faith, and ethics. Engaging with the works of Dawkins, Dennett, and Hitchens, Harris developed a more comprehensive understanding of the ways in which religion can be criticized and the importance of secularism in modern society.

Eastern Philosophy and Mindfulness: Key Practices and Mentors

Another significant influence on Harris’ thinking is his interest in Eastern philosophy and mindfulness practices. He first encountered meditation during a trip to India and Nepal in the late 1980s, which led him to study under various spiritual teachers, including Sayadaw U Pandita and Joseph Goldstein.

These experiences exposed Harris to the ideas and practices of Buddhism, especially the Theravada tradition. The Buddhist concept of “no-self” and the practice of mindfulness meditation have deeply influenced Harris’ work on consciousness, free will, and morality. His exploration of these ideas culminated in the 2014 book “Waking Up: A Guide to Spirituality Without Religion,” in which Harris argues for the value of secular spirituality and meditation.

Contemporary Thinkers and Intellectual Collaborators

Throughout his career, Harris has engaged with a wide range of contemporary thinkers and writers, both as collaborators and intellectual sparring partners. These interactions have further shaped his ideas and allowed him to refine his arguments. Some key figures include:

  • Jordan Peterson: Harris has engaged in numerous debates with the Canadian psychologist and cultural critic, particularly on topics like religion, truth, and morality. These conversations have been instrumental in refining Harris’ thoughts on these subjects.

  • Douglas Murray: The British journalist and author has been a frequent collaborator with Harris, particularly on issues related

    to politics, culture, and the challenges of secularism. Their discussions have helped Harris develop a more nuanced understanding of the sociopolitical landscape.

    • Ayaan Hirsi Ali: As a vocal critic of Islam and advocate for women’s rights, Hirsi Ali has shared the stage with Harris on multiple occasions. Their conversations have influenced Harris’ perspectives on religion, gender, and human rights.

    • Maajid Nawaz: A former Islamist turned counter-extremism activist, Nawaz has collaborated with Harris on issues of radicalization, reform within Islam, and the importance of dialogue between differing perspectives. Their joint work, “Islam and the Future of Tolerance,” showcases the influence of their intellectual exchange.

Philosophical and Scientific Ideas That Shaped Harris' Thinking

In addition to the personal influences mentioned above, a number of key philosophical and scientific ideas have shaped Sam Harris’ intellectual development:

  • Utilitarianism: As a moral philosophy that seeks to maximize happiness or well-being, utilitarianism has greatly influenced Harris’ thinking on ethics. The works of philosophers like Jeremy Bentham and John Stuart Mill provided Harris with a consequentialist framework for understanding morality.

  • Determinism: Harris’ understanding of neuroscience and the nature of the mind has led him to adopt a deterministic view on human behavior and free will. His arguments against the existence of free will have been shaped by the works of philosophers like Baruch Spinoza and neuroscientists like Benjamin Libet.

  • Humanism: Emphasizing the importance of reason, ethics, and critical thinking, humanism has played a crucial role in Harris’ critique of religious dogma and his advocacy for secularism. The ideas of secular humanists like Bertrand Russell and Paul Kurtz have been influential in shaping Harris’ perspectives on human values and ethics.


Sam Harris’ intellectual journey has been shaped by a wide range of influences, from his early education in philosophy and neuroscience to his encounters with prominent thinkers and writers. The key figures and ideas that have shaped Harris’ thinking include ancient philosophers like Plato and Aristotle, neuroscientists like V.S. Ramachandran and Francis Crick, New Atheist collaborators such as Richard Dawkins and Christopher Hitchens, Eastern philosophy and mindfulness practices, and contemporary thinkers like Jordan Peterson and Ayaan Hirsi Ali.

By understanding the various influences on Harris’ intellectual development, we can gain a deeper appreciation for his work and the ideas that have contributed to his unique perspective on topics such as religion, morality, and consciousness.
