In a civilization determined by nearly 2,000 years of Judeo-Christianity, the prisms of analysis have become common to thinkers, philosophies and judgments, forming blinders to the exercise of reason. Michel Onfray, through this homage to popular wisdom and the teachings of nature, proposes to escape from it. Empirical and pragmatic knowledge is placed at the heart of reflection in order to question our relationships with nature, with the life it makes possible, and with the animals that populate it. This second set of Cosmos begins a post-Christian work of building a wisdom armed with reason, a reflection that goes beyond philosophy to include art and the sacred, but also the rhythms and breaths of nature.
