" Typically, a crusade begins when some substantial discrepancy is found between the world as they envision it and the world as it exists. To the anointed, it seems to follow, as the night follows the day, that reality must be brought into line with their vision. Logically, one might just as readily conclude that it is the theory which needs to be brought into line with reality. But that possibility is seldom given much consideration. The fact that reality has survived the test of time and experience, while the viability of their vision has yet to be proven in practice, is likewise seldom given much attention. "
