The concept of infinity in modern mathematical analysis, denoted by ‘∞,’ is a foundational cornerstone in various disciplines, including economics, engineering, finance, and physics. Despite its pervasive application, the profound question of whether the mind can genuinely comprehend the notion of infinity is often overlooked. This thesis seeks to elucidate the intellectual and historical pathways through which the mind conceives the concept of infinity. By employing the framework of metaphysical and mathematical concepts of infinity as outlined by Moore (2019), this study will explore these concepts in depth. Furthermore, it will address the criticisms and challenges associated with the concept of infinity.
