“Harmony, liberal intercourse with all nations, are recommended by policy, humanity, and interest.”

“As Mankind becomes more liberal, they will be more apt to allow that all those who conduct themselves as worthy members of the community are equally entitled to the protections of civil government. I hope ever to see America among the foremost nations of justice and liberality.”

“The Nation, which indulges towards another an habitual hatred, or an habitual fondness, is in some degree a slave. It is a slave to its animosity or to its affection, either of which is sufficient to lead it astray from its duty and its interest. ... The Nation, prompted by ill-will and resentment, sometimes impels to war the Government, contrary to the best calculations of policy. The Government sometimes participates in the national propensity, and adopts through passion what reason would reject; at other times, it makes the animosity of the nation subservient to projects of hostility instigated by pride, ambition, and other sinister and pernicious motives. The peace often, sometimes perhaps the liberty, of Nations has been the victim.”

“I regret exceedingly that the disputes between the protestants and Roman Catholics should be carried to the serious alarming height mentioned in your letters. Religious controversies are always productive of more acrimony and irreconcilable hatreds than those which spring from any other cause; and I was not without hopes that the enlightened and liberal policy of the present age would have put an effectual stop to contentions of this kind.[Letter to Sir Edward Newenham, 22 June 1792]”

“Interwoven as is the love of liberty with every ligament of your hearts, no recommendation of mine is necessary to fortify or confirm the attachment.”

“I hold the maxim no less applicable to public than to private affairs, that honesty is always the best policy.”

“I was sorry to see the gloomy picture which you drew of the affairs of your Country in your letter of December; but I hope events have not turned out so badly as you then apprehended. Of all the animosities which have existed among mankind, those which are caused by a difference of sentiments in religion appear to be the most inveterate and distressing, and ought most to be deprecated. I was in hopes, that the enlightened and liberal policy, which has marked the present age, would at least have reconciled Christians of every denomination so far, that we should never again see their religious disputes carried to such a pitch as to endanger the peace of Society.[Letter to Edward Newenham, 20 October 1792 about violence between Catholics and Protestants]”
