Born in Antwerp in 1624, he studied at the University of Leuven before becoming a professor of philosophy at Ghent. Geulincx developed a unique version of Occasionalism, arguing that physical events occur only by the will of God rather than material interaction. His 'Ethica more geometrico demonstrata' applied mathematical rigor to ethical philosophy, earning praise from later thinkers. Despite his influence on philosophers like Spinoza and Leibniz, he maintained a deeply religious perspective. He spent his final years in Leiden, continuing to teach and write until his death in 1669. His blending of faith and reason marked a distinctive chapter in 17th-century philosophy.

Born in Oklahoma City, Oklahoma, Ken Wilber has become a leading voice in transpersonal psychology and integral studies. He introduced Integral Theory, which proposes a multi-dimensional model of consciousness and reality spanning individual and collective levels. Wilber has authored over twenty-five books, including the Spectrum of Consciousness and A Theory of Everything, which have been translated into dozens of languages. He founded the Integral Institute to foster interdisciplinary research and real-world applications of his ideas. Wilber’s work, synthesizing Eastern and Western thought with modern science, has influenced diverse fields from leadership development to environmental ethics, sparking both admiration and debate.
