Letter to John Jay (15 August 1786) http://gwpapers.virginia.edu/documents/constitution/1784/jay2.html
1780s
Context: If you tell the Legislatures they have violated the treaty of peace and invaded the prerogatives of the confederacy they will laugh in your face. What then is to be done? Things cannot go on in the same train forever. It is much to be feared, as you observe, that the better kind of people being disgusted with the circumstances will have their minds prepared for any revolution whatever. We are apt to run from one extreme into another. To anticipate & prevent disasterous contingencies would be the part of wisdom & patriotism.
What astonishing changes a few years are capable of producing! I am told that even respectable characters speak of a monarchical form of government without horror. From thinking proceeds speaking, thence to acting is often but a single step. But how irrevocable & tremendous! What a triumph for the advocates of despotism to find that we are incapable of governing ourselves, and that systems founded on the basis of equal liberty are merely ideal & falacious! Would to God that wise measures may be taken in time to avert the consequences we have but too much reason to apprehend.
Retired as I am from the world, I frankly acknowledge I cannot feel myself an unconcerned spectator. Yet having happily assisted in bringing the ship into port & having been fairly discharged; it is not my business to embark again on a sea of troubles. Nor could it be expected that my sentiments and opinions would have much weight on the minds of my Countrymen — they have been neglected, tho' given as a last legacy in the most solemn manner. I had then perhaps some claims to public attention. I consider myself as having none at present.

Context: Without knowledge of self there is no knowledge of God.
Our wisdom, in so far as it ought to be deemed true and solid Wisdom, consists almost entirely of two parts: the knowledge of God and of ourselves. But as these are connected together by many ties, it is not easy to determine which of the two precedes and gives birth to the other.
