At the heart of the argument in Kymlicka's book is a principle which is characteristic of liberalism as he conceives it: attachments to a community and to the culture that it embodies are to be honoured as indispensable to intelligible personal choice (p. 47–58, 165–66, 192–93), so long as everyone with the attachments is free to examine them critically and then revise them in any or all of their features (p. 13, 48, 50–51, 167, 172). In one part of the book, the argument moves inward—diastolically—aiming, as the heart is approached, to expose various communitarian objections to liberalism as mistakes about the conditions that liberalism accepts for intelligible personal choice. In the other part of the book, the argument moves outward—systolically—aiming to demonstrate the robust support that liberalism can give the cultures of minority communities like Canadian Indians even when that support requires some restriction of the liberties of other people.
