Conversion denotes a profound transformation of one’s philosophical or existential perspective, often involving a shift from one worldview to another. Philosophers like Gabriel Liiceanu frame it as a radical "leap" requiring a new language and vision, akin to Paul’s religious epiphany.
Henri Bergson reinterpreted it as a movement toward temporal, intuitive awareness, while William James emphasized conversion’s role in acquiring a new life-direction through spiritual insight. These varied approaches underscore conversion’s dual nature—as both a personal transformation and a pivotal moment in intellectual or spiritual development.
