UNFORTUNATELY, THE ENGLISH LANGUAGE does not provide us with a perfect gender-neutral solution to the pronoun problem. I’ve chosen to use “he” throughout the book to refer to nonspecific people. This is for reasons of readability and conciseness only; unless otherwise specified, masculine pronouns do not refer exclusively to men.
