Two classical values that inspired renaissance humanists were Neo-Platonism and Hermeticism. The resurgence of Platos teachings was prevalent in Italy and was instrumental in Medici's attempts to heal the growing schism between the Catholic and Greek Orothodox churches. Hermeticism posited the existence of a single unified theological truth. More generally, both platonism and hermetisciem described that there are essential truths which were a philosophical ancestor to the concept of natural laws which became the foundation first of Humanism, then of the Enlightenment.
