Existence is rational. Questions are reasonable. All questions can ultimately be answered — it’s only a matter of knowledge and time. In short: It’s a rational universe. Things are “figure outable”. Children start out with this unarticulated, but deeply held, conviction. It’s the irrational and dysfunctional people who cause them to later question it. Giving up on this originally valid conviction leads to the unhappiness and internal conflict so prevalent in the world. Holding on to it — or learning how to embrace it once again — is the road back to serenity and happiness in life.
