If a man were to declare, ‘There is a lamp in the next room
which gives no light’, one hearer might be satisfied with his report, but a
wiser man goes into the room to judge for himself, and behold, when he finds
the light shining brilliantly in the lamp, he knows the truth!
- ‘Abdu’l-Baha (From a talk, Paris, November 20, 1911; ‘Paris Talks’)
