for criticism given that it doesn't require proof for belief. Others, however, insist it is as much as any other knowledge, especially when it makes claims that contradict those made by science. There has been much work since the late 20th century by philosophers such as Schellenburg and Moser, and both have written numerous books pertaining to the topic. Much of their work has focused on defining what religion is and specifically what people are skeptical of about it. The work of others have argued for the viability of religious skepticism by appeal to higher-order evidence (evidence about our evidence and our capacities for evaluation), what some call meta-evidence. There are still echoes of early Greek skepticism in the way some current thinkers question the intellectual viability of belief in the divine. In modern times there is a certain amount of mistrust and lack of acceptance of religious skeptics, particularly towards those that are also atheists. This is coupled with concerns many skeptics have about the government in countries, such as the US, where separation of church and state are central tenets.
