In the book’s foreword, Ive explains:

While this is a design book, it is not about the design team, the creative process or product development. It is an objective representation of our work that, ironically, describes who we are. It describes how we work, our values, our preoccupations and our goals. We have always hoped to be defined by what we do rather than by what we say.

We strive, with varying degrees of success, to define objects that appear effortless. Objects that appear so simple, coherent and inevitable that there could be no rational alternative.
