"I espouse reproductive libertarianism, because when everyone has the broadest choice, love itself expands. The affection my family have found in one another is not a better love, but it is another love, and just as species diversity is crucial to sustain the planet, this diversity strengthens the ecosphere of kindness. The road less traveled by, as it turns out, leads to pretty much the same place."

“Children ensnared me the moment I connected fatherhood with loss, but I am not sure I would have noticed that if I hadn't been immersed in this research. Encountering so much strange love, I fell into its bewitching patterns and saw how splendor can illuminate even the most abject vulnerabilities. I had witnessed and learned the terrifying joy of unbearable responsibility, recognized how it conquers everything else. Sometimes, I had thought the heroic parents in this book were fools, enslaving themselves to a life's journey with their alien children, trying to breed identity out of misery. I was startled to learn that my research had built me a plank, and that I was ready to join them on their ship.”

“A wise psychiatrist once said to me, "People want to get better, but they don't want to change." But I would propose that it is only by allowing people born with horizontal identities not to change that one allows them to get better. Any of us can be a better version of himself, but none of us can be someone else.”

“Difference unites us. While each of these experiences can isolate those who are affected, together they compose an aggregate of millions whose struggles connect them profoundly. The exceptional is ubiquitous; to be entirely typical is the rare and lonely state.”

“Insofar as our children resemble us, they are our most precious admirers, and insofar as they differ, they can be our most vehement distractors. From the beginning, we tempt them into imitation of us and long for what may be life's most profound compliment: their choosing to live according to our own system of values. Though many of us take pride in how different we are from our parents, we are endlessly sad at how different our children are from us.”

“I started this book to forgive my parents and ended it by becoming a parent. Understanding backward liberated me to live forward.”

“Insofar as I have written a self-help book, it is a how-to manual for receptivity: a description of how to tolerate what cannot be cured, and an argument that cures are not always appropriate even when they are feasible.”
