William James and the Philosophy of Belief in Living
William James and the Power of Belief
William James was one of America’s most influential philosophers and psychologists. He offered this stirring exhortation during a period when existential anxiety was beginning to grip the modern world. The quote comes from his 1896 essay titled “Is Life Worth Living?”, a piece delivered during an era when philosophical pessimism was fashionable among educated classes. Thinkers like Arthur Schopenhauer and Eduard von Hartmann questioned whether existence itself held meaning. James’s response was characteristically bold and practical. Rather than engaging in abstract metaphysical debates about life’s inherent worth, he proposed something far more radical.
He argued that our beliefs about life’s value actually create that value into being. In the context of the late nineteenth century, industrial society was creating unprecedented wealth. Yet it also created equally unprecedented social dislocation and anxiety. James’s insistence that we possess the power to make life meaningful through our beliefs offered a kind of secular salvation. This resonated with readers struggling to find purpose.
William James was born in 1842 to a wealthy and intellectually accomplished New York family. He grew up surrounded by ideas, philosophy, and a decidedly unconventional approach to education. His father, Henry James Sr., was a Christian theologian and social theorist. He rejected traditional schooling in favor of exposing his children to Europe’s greatest minds and institutions. This peripatetic childhood—moving between New York, London, and Paris—gave young William an unusual education. He learned through literature, art, and philosophical debate rather than rote learning. Yet James’s early life was also marked by profound psychological struggle.
He suffered from recurring bouts of depression, back pain, and what we might today recognize as anxiety disorders. In his twenties, he found himself in a state of genuine despair. He questioned whether he could continue living. He documented this personal crisis in his private journals. It became the crucible from which much of his later philosophy emerged. Unlike many philosophers, James did not theorize about life’s meaning from comfort and stability. He had stared into the abyss and found his way back.
Be not afraid of life. Believe that life is worth living, and your belief will help create the fact
James’s career trajectory was as unconventional as his upbringing. He trained initially as a painter. Then he studied medicine and physiology. He earned his medical degree from Harvard in 1869. However, he did not practice medicine. Instead, he found himself increasingly drawn to psychology and philosophy. In 1875, he established what many regard as the first psychology laboratory in America at Harvard University. He effectively founded American experimental psychology as a discipline.
Yet James was never content to remain merely a scientist in the narrow sense. Throughout his career, he worked to bridge the gap between rigorous empirical investigation and deeper questions. These questions concerned meaning, value, and human purpose—questions that pure science seemed unable to address. This integrative approach combined laboratory precision with philosophical inquiry. It made him a unique figure in American intellectual life. His work remains relevant across multiple disciplines today. These include psychology, philosophy, and business leadership.
Perhaps the lesser-known aspect of James’s life is his struggle with depression. He also experienced what he called his “crisis of faith.” In 1869, at age twenty-seven, James hit psychological rock bottom. His breakdown was so severe that he experienced something approaching a nervous breakdown. He spent months unable to work. Suicidal thoughts plagued him, along with a pervasive sense that life was meaningless. A sudden religious conversion or philosophical revelation did not pull him from this abyss. Rather, he made a decision—almost an act of will. He read the French philosopher Charles Renouvier.
Renouvier proposed that “my first act of free will shall be to believe in free will.” This struck James with revolutionary force. He realized he could choose to believe in life’s worth. This belief was not based on intellectual persuasion or some objective fact. Instead, choosing that belief would be itself a meaningful act. He recorded in his diary that he would henceforth assume his freedom and his life’s worth were real. He committed to living accordingly. This personal transformation became the seed from which his philosophy would grow.
How Your Beliefs Shape Your Reality Today
The philosophy that emerged from James’s recovery became known as pragmatism. It fundamentally challenged the way philosophy had traditionally been practiced. Pragmatism did not ask whether a belief was true in some abstract, absolute sense. Instead, it asked what practical difference that belief made in how one lived. Under this framework, the question “Is life worth living?” is not an objective fact to discover. Rather, it is something more like a choice that becomes true through living it. When James wrote “be not afraid of life,” he was not offering a comforting platitude. He was offering a sophisticated philosophical argument. Fear of life and belief that life is not worth living become self-fulfilling prophecies.
They lead us to withdraw from life. We take fewer risks and engage less deeply with the world around us. This makes life objectively less rich and meaningful. Conversely, the belief that life is worth living, held as a conscious commitment, leads us to engage more fully. We take reasonable risks. We form deeper connections. We pursue meaningful goals. All of these actually do make life more worth living.
Over the decades since James wrote these words, countless contexts have invoked them. Self-help literature, therapeutic practice, and motivational speaking all drew upon his ideas. During the tumultuous 1960s, a new generation questioned the value and meaning of the society they had inherited. James’s philosophy experienced a renaissance. His insistence that individual belief and choice could reshape reality resonated with the counterculture’s focus on consciousness and personal transformation. In more recent times, his ideas have been appropriated (sometimes loosely) by positive psychology and the self-help industry.
