Maritain considered that a true humanism to be grounded on all aspects of humanity. Coming from the Thomist understanding of human nature as both divinity and humanity, he mentions the concept of integral humanism, not only to critique the inadequacy of the concept of humanism from the Renaissance to now, but also attempt to explore the possibility of a transcendent humanism. Integral humanism is constructed on the two characteristics of authenticity and transcendence. In fact, the main point in Maritain's intergral humanism is the concept of transcendence, which requires not only a simple transcendence of other species, but a transcendence toward the divine nature.
