James M. Buchanan in “Natural and Artifactual Man” from Liberty Press’ What Should Economists Do?:
Man wants liberty to become the man he wants to become. He does so precisely because he does not know what man he will want to become in time…. Man does not want liberty in order to maximize his utility, or that of the society of which he is a part. He wants liberty to become the man he wants to become.
