When we lose the right to be different, we lose the privilege to be free. - Charles Evans Hughes

We still proclaim the old ideals of liberty but we cannot voice them without anxiety in our hearts. The question is no longer one of establishing democratic institutions but of preserving them. … The arch enemies of society are those who know better but by indirection, misstatement, understatement, and slander, seek to accomplish their concealed purposes or to gain profit of some sort by misleading the public. The antidote for these poisons must be found in the sincere and courageous efforts of those who would preserve their cherished freedom by a wise and responsible use of it. Freedom of expression gives the essential democratic opportunity, but self-restraint is the essential civic discipline.

The most ominous spirit of our times, as it seems to me, is the indication of the growth of an intolerent spirit. It is the more dangerous when armed, as it usually is, with sincere conviction. It is a spirit whose wrath must be turned away by the soft answers of a sweet reasonableness. It can be exorcised only by invoking the Genius which watched over our infancy and has guided our development— a good Genius— still potent let us believe — the American spirit of civil and religious liberty. Our institutions were not devised to bring about uniformity of opinion; if they had we might well abandon hope. It is important to remember, as has well been said, "the essential characteristic of true liberty is that under its shelter many different types of life and character and opinion and belief can develop unmolested and unobstructed."

…[I]n three notable instances the Court has suffered severely from self-inflicted wounds. The first of these was the Dred Scott case. … There the Supreme Court decided that Dred Scott, a negro, not being a citizen could not sue in the United States Courts and that Congress could not prohibit slavery in the territories. … [T]he grave injury that the Court sustained through its decision has been universally recognized. Its action was a public calamity. … [W]idespread and bitter attacks upon the judges who joined in the decision undermined confidence in the Court. … It was many years before the Court, even under new judges, was able to retrieve its reputation.…[The second instance was] the legal tender cases decided in 1870. … From the standpoint of the effect on public opinion there can be no doubt that the reopening of the case was a serious mistake and the overruling in such a short time, and by one vote, of the previous decision shook popular respect for the Court.… [The third instance happened] [t]wenty-five years later, when the Court had recovered its prestige, [and] its action in the income tax cases gave occasion for a bitter assault. … [After questions about the validity of the income tax] had been reserved owing to an equal division of the Court, a reargument was ordered and in the second decision the act was held to be unconstitutional by a majority of one. Justice Jackson was ill at the time of the first argument but took part in the final decision, voting in favor of the validity of the statute. It was evident that the result [holding the statute invalid] was brought about by a change in the vote of one of the judges who had participated in the first decision. … [T]he decision of such an important question by a majority of one after one judge had changed his vote aroused a criticism of the Court which has never been entirely stilled."
