““The coercion which a government must still use … is reduced to a minimum and made as innocuous as possible by restraining it through known general rules, so that in most instances the individual need never be coerced unless he has placed himself in a position where he knows he will be coerced. Even where coercion is not avoidable, it is deprived of its most harmful effects by being confined to limited and foreseeable duties, or at least made independent of the arbitrary will of another person. Being made impersonal and dependent upon general, abstract rules, whose effect on particular individuals cannot be foreseen at the time they are laid down, even the coercive acts of government become data on which the individual can base his own plans.””
