But the world can be different and we can make it so. Let's borrow a concept from biology. Gestation means the amount of time from conception it takes for an organism to grow into a form in which it can emerge into the world at large. Fruit flies gestate in eleven minutes. For most mammals, the process takes several months.
Ideas also gestate.
When America declared itself a free country well over twenty percent of its population were slaves. It took almost a hundred years for Lincoln to free the slaves and almost another hundred years for the civil rights movement to translate these principles into reality. Ideas take time to take hold. The more profound and novel the idea, the longer the gestation period. That's about the length of the gestation period necessary for it to realize that it's G-d's dwelling.
