““The rule of law does not guarantee economic security, social status, or even minimal happiness to anyone. Thus it should not be confused either with the utopian scheme of the worldly philosophers or the divine outline of the City of God. Recognizing the human impossibility of the former and the present lack of the latter, the authors of our Constitution wisely selected as their guiding principle the rule of law which guarantees us nothing more than the absence of arbitrary coercion. Of course, the rule of law does not imply any general prohibition against affirmative government action in the protection of individuals or in pursuit of the general welfare. Rather it simply marks out certain limits to the use of any governmental coercion.””
