In his personal intercourse he is peculiarly bland and urbane, one of the few men capable of conducting an argument on the most interesting subject without the slightest apparent excitement of voice or manner, allowing his adversary every polite advantage and admitting all his just statements with perfect fairness. It is said that a fiery young southerner once fell into a discussion on slavery with him when he was travelling incog., on board a steamboat. Garrison quite won his heart by the fairness and courtesy with which he discussed the subject, and brought him to admissions which the frank southerner in a good humor was quite willing to make. On parting he said to him, "If that Garrison there in Boston were only like you, we should be more ready to listen to him." A great deal of this amiability doubtless is owing to the singular steadiness and healthiness of Garrison's nervous system. In this he was one of the most peculiarly constituted men, in whom nature ever combined traits expressly for a great work. All his personal habits are those of a methodical unexcitable man, and not in the least like the hurry and enthusiasm of a fanatic. He is methodical, systematic and precise in all his arrangements, neat and careful in respect to the minutest trifle. His handwriting is always of the finished completeness of a writing master, and in the most vehement denunciations, not a letter was ever misplaced or a comma or exclamation point, omitted. Every thing he ever wrote was perfected for the press as it left his pen. Such habits as these speak a composed and equable nervous system. In fact, Garrison's nerves never knew what it was to shiver and vibrate either with irritation or with fear. He is gifted with the most perfect imperturbable cheerfulness, which no outward discomposure seems to have any power to shake. His politely bowing to the furious Boston mob before descending to put himself in their hands, is a very characteristic thing, and during all the tossings and tumults of the hour that followed, Garrison was probably the serenest person that ever had his clothes torn off his back for expressing his opinions. That language in the Liberator which looked to the world as if it must have been uttered in a passion, because it was so far above the usual earnestness of expression on such subjects, was in his case the result of a deliberate system. Garrison said that the world blinded conscience and made false issues with itself by the habitual calling of things by the wrong names; that there was no kind of vice which might not be disguised under a polite phrase. Theft might be spoken of as an ingenious transfer of property--adultery as a form of the elective affinity, and so on, but that all such phraseology had an immoral tendency. In like manner the stealing of men and women from Africa--the systematic appropriation of all the fruits of their industry and labor--was robbery. Whoever did this was a thief.
