“Every education teaches a philosophy; if not by dogma then by suggestion, by implication, by atmosphere. Every part of that education has a connection with every other part. If it does not all combine to convey some general view of life, it is not education at all” (G.K. Chesterton, The Common Man).
Not only are philosophical and theological assumptions inevitable, they are fundamental.
Since we become what we perceive, it is wise to take great care with the premises of our perceptions.
