Most acknowledgments prefacing substantial studies have somewhere in the text a phrase like: "I could not have done this without the help of," or "I owe it all to." I used to think such sentiments trite; now I know their weightiness. I could not have done this without the help of a long list of people who stimulated and supported me. I owe most of the good ideas to others; responsibility for the poor ones, and any mistakes I made, rest squarely on my shoulders.
Without a doubt, the one who sacrificed most for this work was my wife Lori. Not only did she serve as chief and, most often, sole bread-winner in the family during much of the time I worked on this book, but she also spent seven months with a two-year-old in a tiny apartment in dark, wintery Oslo while I was out collecting materials. In addition, she gave up countless hours of her own time, and time we could have shared, to see that I was free to work. More remarkably, in a world where "right" too often supersedes "duty," she did it all without a word of complaint. Her steadfast love and ready smile lessened my burden tremendously.
My five-year-old daughter Kirsten betrays the sacrifice she has made with her frequent question: "Do you have to work today Daddy?" She will never know how much she has contributed to this enterprise by just being my little girl. My year-old son Evan joined this project late, but his arrival reminded me that there were more important things in life than writing books. My parents, Lois and Frank Nelsen, have also provided time, money, and prayers to this venture. Their encouragement was especially important.
While my family provided personal support, many others provided professional guidance. I am particularly indebted to those who took time to read drafts of this book. These include Professors Barbara
