There are two kinds of intellectual: Philosophers and Sophists. The former seek the absolute truth while the latter seek the “practical” truth that brings them worldly prestige and success. The weak-minded are far more influenced by Sophists than Philosophers, to the severe detriment of the intellectual progress of humanity. Philosophers have a position based on rationalism, idealism, metaphysics and mathematics, while Sophists hold a position reflecting empiricism, materialism, physics and science. One of the most prominent Sophists in today’s world is Sam Harris, an American controversialist who supports scientism, atheism, and the claim that free will is illusory. All of his positions are closely connected, and the purpose of this book is to expose the fallacies that lie at the heart of the Sophists’ worldview, and Harris’s in particular. Ultimately, the difference between Philosophy and Sophistry reduces to the difference between mathematics and science, and how each relates to ultimate reality.
