'No great thing cometh suddenly into being, for not even a bunch of grapes can, or a fig. If you say to me now: I desire a fig, I answer that there is need of time: let it first of all flower, and then bring forth the fruit, and then ripen. When the fruit of a fig-tree is not perfected at once, and in a single hour, would you win the fruit of man's mind thus quickly and easily? Even if I say to you, expect it not.'
