Nothing makes one so dizzy as human reasoning, which sees everything from an earthly point of view, and does not allow illumination from above. Earthly reasoning is covered with mud. Therefore, we have need of streams from above, so that, when the mud has fallen away, whatever part of the reason is pure may be carried on high and may be thoroughly imbued with the lessons taught there. This takes place when we manifest both a well-disposed soul and an upright life.
- St. John Chrysostom
as quoted on God's Politics
