Encyclopedia of the Philosophical Sciences (1816)
Context: A philosophy without heart and a faith without intellect are abstractions from the true life of knowledge and faith. The man whom philosophy leaves cold, and the man whom real faith does not illuminate, may be assured that the fault lies in them, not in knowledge and faith. The former is still an alien to philosophy, the latter an alien to faith.

Source: Hainish Cycle, The Telling (2000), Ch. 4, §3 (pp. 90–91)
Context: One of the historians of Darranda said: To learn a belief without belief is to sing a song without the tune.
A yielding, an obedience, a willingness to accept these notes as the right notes, this pattern as the true pattern, is the essential gesture of performance, translation, and understanding. The gesture need not be permanent, a lasting posture of the mind or heart, yet it is not false. It is more than the suspension of disbelief needed to watch a play, yet less than the conversion. It is a position, a posture in the dance.

Variant: For those with faith, no evidence is necessary; for those without it, no evidence will suffice.
