The State insists that, by thus quarantining the general reading public against books not too rugged for grown men and women in order to shield juvenile innocence, it is exercising its power to promote the general welfare. Surely this is to burn the house to roast the pig...The incidence of this enactment is to reduce the adult population of Michigan to reading only what is fit for children.

Certainly the affirmative pursuit of one's convictions about the ultimate mystery of the universe and man's relation to it is placed beyond the reach of law.
