His abilities were, perhaps, somewhat overrated in the admiring judgment of his contemporaries. His style as a writer was copious and energetic; but it was sometimes careless, coarse and even incorrect. His eloquence was better adapted to popular assemblies than to the graver occasions of legislative debate; in the halls of justice, it produced a greater effect on the jury than on the judge. "The few fragments of his speeches that were reported and are now extant give no idea of the enthusiasm that was created by their delivery. The elevation of his mind, and the known integrity of his purposes, enabled him to speak with decision and dignity, and commanded the respect as well as the admiration of his audience." While his arguments were sometimes comprehensive and varied, they generally related only to a few points which they placed in a very clear and convincing light. His object was immediate effect. He had studied the art of clear expression and forcible argument in order to act with facility and force upon the minds of others to such an extent as to convince them, and then to convert their conviction into action. He employed the facility and the power thus gained not for any personal agrandizement, but to advocate political reform for the good of the whole people. In the latter part of his speech on the Writs of Assistance, he discussed the incompatibility of the acts of trade as lately adopted by the English Ministry with the charter of the colony. In so doing "he reproached the nation, Parliament, and King," says John Adams, "with injustice, illiberality, ingratitude, and oppression, in their conduct towards the people of this country, in a style of oratory that I never heard equalled in this or any other country." As to the effect of this oration in increasing the courage of the colonists, inciting them to scrutinize more closely and resist more strenuously, the claims of the British Ministry and Parliament, we have Adams's significant statement,-- "I do say in the most solemn manner that Mr. Otis's oration against Writs of Assistance breathed into this nation the breath of life." The longest and most elaborate production from his pen is the pamphlet on the "Rights of the Colonies." It affords a fair specimen of his impetuous and inaccurate rhetoric, his rapid and eager manner of accumulating facts, arguments, and daring assertions, and the "glowing earnestness and depth of patriotic feeling with which all his compositions are animated." It is not surprising that a book written in this style caused the author to be suspected of wildness and even of madness. But there was, as Bowen remarks, a method and a good deal of logical power in his madness.
