Epilogue

Our quest for knowledge began with our evolution as a species 200,000 years ago. We hunted and gathered, painted on caves, told stories, domesticated animals and plants, wondered about nature, gave birth to civilization and religion, picked up writing, philosophized, and engaged in science. In fact, we keep on doing all these wonderful things and continue to learn more and more, but, why should we? A student of Euclid once asked, What would I earn if I learned geometry? If you should earn from what you learn, here is a coin, Euclid responded sardonically. But, really, why should we learn? Because we can, might be the best answer, but also because the journey of knowledge is infinitely interesting. Nonetheless, in front of the wisdom of the universe, we should remain always humble, for as many learned people have come to know (Democritus, Socrates, Russell), we might be wrong on just about everything.
