Here's a exerpt that moved me. (This is the character Waddington speaking to Kitty after Walters death).
"I wonder. I wonder if it matters that what they have aimed at is illusion [referring to eternal life]. Their lives are in themselves beautiful. I have an idea that the only thing which makes it possible to regard this world we live in without disgust is the beauty which now and then men create out of the chaos. The pictures they paint, the music they compose, the books they write, and the lives they lead. Of all these the richest in beauty is the beautiful life. That is the perfect work of art."
Although I believe that there are many ways that we can view this world without disgust and that there is eternal life, I love that without those beliefs it can come down to the simple idea that a beautiful life, IS the richest beauty. We don't have to be musically inclined, know how to write eloquently or paint like a master, we can lead a life of virtue and integrity and charity and be as fulfilled as that person who painted a masterpiece because a good life IS beautiful.
