Truths, no matter how momentous or enduring, are nothing to the individual until he appreciates them, and feels their force, and acknowledges their sovereignty. He cannot bow to their majesty until he sees their power. All the blind then, and all the ignorant--that is, all the children--must be educated up to the point of perceiving and admitting the truth, and acting according to its mandates.
