Know everything? Were we even listening in Intro to Philosophy? Did we miss the part where Socrates, who supposedly said, "I know that I know nothing," developed an entire method of figuring out stuff based entirely on inquiry? And that all knowledge exists precisely because people have, persistently and for centuries, asked tons and tons of questions?
Have we established that questions are marvelous, momentous things? If so, can we agree that asking ourselves the right ones can have life-altering effects? Because have you ever noticed how questions prevent us from settling for less than we deserve? That asking ourselves "Could it be better?" is a great way to make things, well, a whole lot better? That a bunch of our breakthroughs, triumphs and joys occurred when we asked a few big, bold, paradigm-shifting questions? Don't we owe it to ourselves—don't we deserve—to live an examined life? Can it be said that asking questions is what keeps us honest, drives us to aim higher—and is the very thing that makes us human?
In a word? Yes. No question about it.
