The character of his mind, as well as the outward circumstances of his life, predisposed Samuel Adams to think that a great crisis in the history of America and of the world confronted the men of Boston. There was in him some innate scholastic quality, some strain of doctrinaire Puritan inheritance diverted to secular interests, that gave direction to all his thinking. In 1743, upon receiving the degree of Master of Arts from Harvard College, he argued the thesis, "Whether it be lawful to resist the Supreme Magistrate, if the Commonwealth cannot otherwise be preserved." We may suppose that the young man acquitted himself well, reasoning with great nicety in favor of the legality of an illegal action, doubtless to the edification of Governor Shirley, who was present and who perhaps felt sufficiently remote from the performance, being himself only an actual supreme magistrate presiding over a real commonwealth. And indeed for most young men a college thesis is but an exercise for sharpening the wits, rarely dangerous in its later effects. But in the case of Samuel Adams, the ability to distinguish the speculative from the actual reality seemed to diminish as the years passed. After 1764, relieved of the pressure of life's anxieties and daily nourishing his mind on premises and conclusions reasonably abstracted from the relative and the conditioned circumstance, he acquired in a high degree the faculty of identifying reality with propositions about it; so that, for example, Liberty seemed threatened if improperly defined, and a false inference from an axiom of politics appeared the same as evil intent to take away a people's rights. Thus it was that from an early date, in respect to the controversy between the colonies and the mother country, Samuel Adams became possessed of settled convictions that were capable of clear and concise presentation and that were at once impersonal and highly subjective, for which outward events--the Stamp Act, the Townshend duties, the appointment of Thomas Hutchinson as Governor, or whatever--furnished as it were the suggestion only, the convictions themselves being largely the result of inward brooding, the finespun product of his own ratiocinative mind.
