But the difficulty is, that a right which all men claim for themselves, with the most sensitive and pertinacious inflexibility, they have not yet learned to accord to their fellow men, in cases where their own interests are involved. Every man is saying, "Let me have full liberty to propagate my opinions, and to oppose all that I deem wrong and injurious, but let no man take this liberty with my opinions and practices. Every man may believe what he pleases, and propagate what he pleases, provided he takes care not to attack any thing which belongs to me." And how do men exert themselves to restrain this corresponding right of their fellow men? Not by going to the magistrate to inform, or to the spiritual despot to obtain ecclesiastical penalties, but he resorts to methods, which, if successful, are in effect the most severe pains and penalties that can restrain freedom of opinion. What is dearer to a man than _his character_, involving as it does, the esteem, respect and affection of friends, neighbours and society, with all the confidence, honour, trust and emolument that flow from general esteem? How sensitive is every man to any thing that depreciates his intellectual character! What torture, to be ridiculed or pitied for such deficiencies! How cruel the suffering, when his moral delinquencies are held up to public scorn and reprehension! Confiscation, stripes, chains, and even death itself, are often less dreaded. It is this method of punishment to which men resort, to deter their fellow-men from exercising those rights of liberty which they so tenaciously claim for themselves. Examine now the methods adopted by almost all who are engaged in the various conflicts of opinion in this nation, and you will find that there are certain measures which combatants almost invariably employ. They either attack the intellectual character of opponents, or they labour to make them appear narrow-minded, illiberal and bigoted, or they impeach their honesty and veracity, or they stigmatize their motives as mean, selfish, ambitious, or in some other respect unworthy and degrading. Instead of truth, and evidence, and argument, personal depreciation, sneers, insinuations, or open abuse, are the weapons employed. This method of resisting freedom of opinions, by pains and penalties, arises in part from the natural selfishness of man, and in part from want of clear distinctions as to the rights and duties involved in freedom of opinion and freedom of speech. The great fundamental principle that makes this matter clear, is this, that a broad and invariable distinction should ever be preserved between the _opinions_ and _practices_ that are discussed, and the _advocates_ of these opinions and practices.
