“In general, human societies are not innovative. They are hierarchical and ritualistic. Suggestions for change are greeted with suspicion: they imply an unpleasant future variation in ritual and hierarchy: an exchange of one set of rituals for another, or perhaps for a less structured society with fewer rituals.

Because it is only when we are suspended in mid-air with no landing in sight, that we force our wings to unravel and alas begin our flight. And as we fly, we still may not know where we are going to. But the miracle is in the unfolding of the wings. You may not know where you're going, but you know that so long as you spread your wings, the winds will carry you.”
― C. JoyBell C.

“People have ideas. They live in their ideas, do you understand? And those ideas, whatever they happen to be, make all the difference.”
