“Independence I have long considered as the grand blessing of life, the basis of every virtue; and independence I will ever secure by contracting my wants, though I were to live on a barren heath.”

Context: I long to hear that you have declared an independency. And by the way, in the the new Code of Laws which I suppose it will be necessary for you to make I desire you would Remember the Ladies, and be more generous and favourable to them than your ancestors. Do not put such unlimited power into the hands of the Husbands. Remember all Men would be tyrants if they could. If particular care and attention is not paid to the Ladies we are determined to foment a Rebellion, and will not hold ourselves bound by any Laws in which we have no voice, or Representation.
That your Sex are Naturally Tyrannical is a Truth so thoroughly established as to admit of no dispute, but such of you as wish to be happy willingly give up the harsh title of Master for the more tender and endearing one of Friend. Why, then, not put it out of the power of the vicious and the Lawless to use us with cruelty and indignity with impunity? Men of Sense in all Ages abhor those customs which treat us only as the vassals of your sex; regard us then as Beings placed by Providence under your protection, and in imitation of the Supreme Being make use of that power only for our happiness.
