“We confess knowledge without certainty, truth without objectivity.”

“It is precisely this refusal of the Cartesian paradigm that characterizes Radical Orthodoxy, which seeks to reanimate the account of knowledge offered by Augustine and Aquinas. On this ancient-medieval-properly-postmodern model, we rightly give up pretensions to absolute knowledge or certainty, but we do not thereby give up on knowledge altogether. Rather, we can properly confess that we know God was in Christ reconciling the world to himself, but such knowledge rests on the gift of (particular, special) revelation, is not universally objective or demonstrable, and remains a matter of interpretation and perspective (with a significant appreciation for the role of the Spirit's regeneration and illumination as a condition for knowledge). We confess knowledge without certainty, truth without objectivity.”

“If in other sciences we should arrive at certainty without doubt and truth without error, it behooves us to place the foundations of knowledge in mathematics...”

“Our aim as scientists is objective truth; more truth, more interesting truth, more intelligible truth. We cannot reasonably aim at certainty. Once we realize that human knowledge is fallible, we realize also that we can never be completely certain that we have not made a mistake.”

“ No one can surely know what knowledge is without the presence of truth.”

“Psychoanalysis is confession without absolution.”
