The Intellectual Foundation of the Enlightenment: Preparatory Factors and Philosophical Transformation

Upon examining the history of philosophy, it becomes evident that since antiquity, societies have sought to determine “humanity’s place and purpose in this world” and endeavored to formulate answers to these questions. However, it is observable that whenever societal values deteriorate throughout human history, solutions to rectify this decline begin to be pursued. The 18th-century Enlightenment Philosophy emerged in Europe during a period when individuals were regressing, particularly in intellectual terms, due to the oppressive attitudes of the Church and authoritarian institutions. Marking the decline of medieval thought and the rise of Renaissance ideas, the Enlightenment represents an era in which fragmented, divergent, and conflicting intellectual currents of the preceding century gave way to the systematization of thought. The Age of Enlightenment brought about profound transformations across numerous domains—from theories of reason and knowledge to social and political reforms, from conceptions of religion and God to aesthetics and ethics. These changes not only reshaped Europe but also generated repercussions that influenced nearly all of humanity. In this context, research demonstrates that Enlightenment Philosophy constituted an era of profound and comprehensive transformation for Europe in every respect. By embracing reason as its foundational principle, the Enlightenment marked a period of significant advancements in science and philosophy across 18th-century Europe. In this article, we will examine the nature of the Enlightenment, the philosophical movements underlying it, and the intellectual transformation it engendered.
