““We'll learn more about how the brain operates, how matter works, and what fills up empty space. But even if we evolve into a smarter, wiser species in possession of a truckload of new scientific knowledge, we will still have no access to ultimate answers. When a smart person finally admits that some mysteries can't be solved, she can relax and rejoice. When you honor what you know to be true, that nobody knows the ultimate answers, that there is a difference between what is not yet known and what can't be known, that guesses don't really count, and that easy answers like sitting on a mat or walking in nature may soothe you but answer nothing, then you can leave mysticism behind. Then you are ready for the answer: that you are obliged to take charge of the project of your life.””
