Speculative philosophy is philosophy that seeks to reflect on all aspects of human experience to construct a comprehensive view of reality.[1] Its aim is to integrate the insights from various domains into a unified understanding of existence.[1][2]
Historically, speculative philosophy has been central to the work of philosophers like Plato, Georg Wilhelm Friedrich Hegel, and Alfred North Whitehead, who all developed large-scale theories about reality, existence, and knowledge.[2] The term was coined by C. D. Broad as a distinction from critical philosophy.[1]
