I also read a chapter of "The Way We Are" by Wheelis. This chapter was on desire and it had some really good (and long) quotes. I chose only 2 to put on here. Enjoy.
"I am full of desire. Never straight up, balanced, but always learning, I fall in love easily, a small push will do it. And when it happens I always feel I am possessed by—am in possession of—something unique and precious, something that alone can lift me up out of the flat world of dailiness into the higher realm for which life must be destined. Then I want desperately for it to last forever. And when it crumbles, as it always does, I find that I had been in possession only of something ordinary."
"Desire is endless and unappeasable, it is most intense where most forbidden, and is never far from despair."
