“The meaning of life is something we are using creativity to discover, to build. We can’t find the meaning of life in the world ‘out there’, nor just by pure thought, or by reference to an authority. What we have to do is form explanations about what is right and wrong, what is better and worse, what is beautiful and ugly, and hone those theories, while also trying to meet them. At any one moment, we will meet them imperfectly, just like scientific theories, at any one moment, are only an imperfect explanation of what the physical world is like. But, through criticism and conjecture and seeking the truth, we can resolve the errors in what we had previously thought and thereby make progress.”
