But the solution to the riddle of life and space and time lies outside space and time. For, as it should be abundantly clear by now, nothing inside a frame can state, or even ask, anything about that frame. The solution, then, is not the finding of an answer to the riddle of existence, but the realization that there is no riddle. This is the essence of the beautiful, almost Zen Buddhist closing sentences of the Tracticus: "For an answer which cannot be expressed the question too cannot be expressed. The riddle does not exist."
