Why ask "Why?" questions?

".. people express a motivation not seen in any other animal species - a yearning for a sense of purpose."

"We want to make sense of what we see around us and to ask: What is the nature of the universe? What is our place in it and where did it and we come from? Why is it the way it is?" Hawking, "Brief History of Time"

"Why have you remained curious? Perhaps it's because you have some measure of confidence that meaningful answers can be found. Somehow that confidence -- or longing-- has been kept alive."

"Test everything. Hold onto the good." 1 Th 5:21
