It would be a folly for me to attempt to change the general disposition of mankind, or to flatter my self with the hopes of a different conduct from those who may be employed in the various branches of the department, than what is known to influence and govern men. If experiments are necessary, I have not the least objections to their being made; but I cannot agree to be responsible for the consequences. If government is distressed, and these expedients are requisite for her relief, my aid shall not be wanting, during my stay in the department, to give them a fair and full operation; but I cannot say that I think they will either answer the expectations of the public, or prove competent to the demands of the army.

Letter to George Washington (January 1780)
