What is education? Andragogy and Pedagogy are two approaches to education. The word Education derives from the Latin "educare" -- "to bring up", from e- "out" and ducere "to lead; to bring forward". (Latin root) Such a definition presupposes something is present to bring forward. In other words, humans are not 'tabula rasa' (blank slate) at birth but born with innate skills and capabilities to be nurtured, developed. Moreover, ALL education is religious in nature whether based upon the absolutist values of Judaism or Christianity, or the relativistic, ever changing base of Humanism.
This definition opens up the inquiry to far more than just the late-nineteenth and 20th century Humanism propounded by Dewey and his fellow travelers. It opens up to consideration successful education systems from history as well as those that, despite humanist efforts, have survived and flourished.
Open inquiry is defined as accepting of all intellectually supported positions not just those that are comfortable and familiar. The intellectual liberal is the accepting individual. The intellectual dwarf is not.
