One of the first projects to which the Government of the Revolution addressed itself was the reformation of manners—­a purpose at once commendable in itself and politically useful as distinguishing the new Government from the old.  Even while the King was absent in Ireland at the beginning of his reign, the Queen issued a letter calling upon all justices of the peace and other servants of the Crown to exert themselves in suppressing the luxuriant growth of vice, which had been fostered by the example of the Court of Charles.  On the conclusion of the war in 1697, William issued a most elaborate proclamation to the same effect, and an address was voted by Parliament, asking his Majesty to see that wickedness was discouraged in high places.  The lively pamphlet in which Defoe lent his assistance to the good work entitled The Poor Man’s Plea, was written in the spirit of the parliamentary address.  It was of no use to pass laws and make declarations and proclamations for the reform of the common plebeii, the poor man pleaded, so long as the mentors of the laws were themselves corrupt.  His argument was spiced with amusing anecdotes to show the prevalence of swearing and drunkenness among members of the judicial bench.  Defoe appeared several times afterwards in the character of a reformer of manners, sometimes in verse, sometimes in prose.  When the retort was made that his own manners were not perfect, he denied that this invalidated the worth of his appeal, but at the same time challenged his accusers to prove him guilty of any of the vices that he had satirised.

It is impossible now to ascertain what induced Defoe to break with the Dissenters, among whom he had been brought up, but break with them he did in his pamphlet against the practice of Occasional Conformity.  This practice of occasionally taking communion with the Established Church, as a qualification for public office, had grown up after the Revolution, and had attracted very little notice till a Dissenting lord mayor, after attending church one Sunday forenoon, went in the afternoon with all the insignia of his office to a Conventicle.  Defoe’s objection to this is indicated in his quotation, “If the Lord be God, follow Him, but if Baal, then follow him.”  A man, he contended, who could reconcile it with his conscience to attend the worship of the Church, had no business to be a Dissenter.  Occasional conformity was “either a sinful act in itself, or else his dissenting before was sinful.”  The Dissenters naturally did not like this intolerant logical dilemma, and resented its being forced upon them by one of their own number against a practical compromise to which the good sense of the majority of them assented.  No reply was made to the pamphlet when first issued in 1698; and two or three years afterwards Defoe, exulting in the unanswerable logic of his position, reprinted it with a prefatory challenge to Mr. Howe, an eminent Dissenting minister.
