"Over the years I have come to appreciate how elusive the answers to those questions can be. During my first book tour 15 years ago, an interviewer noted that the paleontologist Stephen Jay Gould had dedicated his first book to his father, who took him to see the dinosaurs when he was 5. What was the event that made me become a cognitive psychologist who studies language? I was dumbstruck. The only thing that came to mind was that the human mind is uniquely interesting and that as soon as I learned you could study it for a living, I knew that that was what I wanted to do. But that response would not just have been charmless; it would also have failed to answer the question. Millions of people are exposed to cognitive psychology in college but have no interest in making a career of it. What made it so attractive to me?
As I stared blankly, the interviewer suggested that perhaps it was because I grew up in Quebec in the 1970s when language, our pre-eminent cognitive capacity, figured so prominently in debates about the future of the province. I quickly agreed — and silently vowed to come up with something better for the next time. Now I say that my formative years were a time of raging debates about the political implications of human nature, or that my parents subscribed to a Time-Life series of science books, and my eye was caught by the one called “The Mind,” or that one day a friend took me to hear a lecture by the great Canadian psychologist D. O. Hebb, and I was hooked. But it is all humbug. The very fact that I had to think so hard brought home what scholars of autobiography and memoir have long recognized. None of us know what made us what we are, and when we have to say something, we make up a good story."
