This book presents a profound theoretical investigation into the "hidden structures" that precede and shape human knowledge. Dr. elKhalil Baroudi argues that scientific knowledge is not a passive discovery of an objective reality, but rather a "manufactured" product emerged through biological, linguistic, and cultural filters.By analyzing major scientific revolutions-from Copernican heliocentrism to the complexities of quantum mechanics-the book reveals how epistemic limits function not merely as barriers, but as productive mechanisms that define the conditions of truth. The work introduces the groundbreaking concept of the "Manufactured Subject," suggesting that human beings as epistemic agents are constituted within specific knowledge regimes rather than standing as neutral observers outside them.A vital contribution to the philosophy of science and epistemology, this monograph bridges the gap between the rigor of theoretical physics and the depth of critical theory. It calls for a necessary "epistemic humility" and a pluralistic approach to understanding the multifaceted nature of reality.
