Rūḥ'ha-yi bīmār ẕihn'hā-yi sālim: Persiska (Farsi) 1401

William James, the American philosopher and the founder of the philosophy of pragmatism were on the brink of collapse at the threshold of adulthood. But he was able to free himself from the dark well that he was trapped in, and during the next decades of his life, he became the father of American philosophy and psychology. James's problem was not that he did not want to do anything and spend his life in vain; Rather, his problem was that his heart wanted to do many different things at the same time, and because the limited time of human life did not allow him to do this, he was deeply disappointed. In addition, from the very beginning of his youth, James was involved in deep philosophical issues and questions that occupied the minds of great thinkers throughout history. He believed that people like himself are sick souls for whom life is difficult and facing its meaninglessness can drive them to the border of madness. In the face of these overwhelming challenges, James founded a philosophy that he called a philosophy for having a healthy mind. Since most of us humans, especially in the modern age, are teetering on the edge of the abyss, the philosophy of William James can be our guide in continuing the challenging and winding path of life. In the book Sick Souls, Healthy Minds, John Kaag, while describing his encounter with the philosophy of William James, introduces the reader to the foundations of his deep and spiritual thought and shows how a philosophy for having healthy minds Facing the abyss of existence, it can guide people in a path that leads to a happy, healthy, purposeful and at the same time deep and meaningful life.
