In this groundbreaking book, Edgar N. Weaver confronts the alarming possibility of humanity’s extinction within the next few centuries, citing scientific evidence and predictions. The book does not dwell on dystopian visions but rather offers a roadmap for navigating this crisis. The author introduces the concept of three interconnected “circuitries” within our minds: Self, Spirit, and Emotion. By understanding and cultivating the often-overlooked “Circuitry of Spirit”—our innate capacity for benevolence and ethical decision-making—we can create a more harmonious and sustainable future. “Mindset of Spirit” argues that shifting our focus from individual gain to the collective good, guided by the Circuitry of Spirit, is the key to overcoming existential threats and building a world where all can flourish.
