This is an introduction to the Reformed Epistemology (RE) movement that was particularly associated with the philospher Alvin Plantinga. Plantinga was interested in establishing the grounds on which a belief might be considered “rational (reasonable)”.

RE was known for proposing that theistic beliefs can be held to be properly basic and therefore do not require “evidence” for it to be rational to hold them.
