gardens, rivers, every object wore its liveliest hue!  Whence did they borrow it?  From the presence of our charming companion.  They were pleasing, because she seemed pleased.  Alone, the scene would have been dull and insipid:  the participation of it with her gave it relish.  Let the gloomy monk, sequestered from the world, seek unsocial pleasures in the bottom of his cell!  Let the sublimated philosopher grasp visionary happiness, while pursuing phantoms dressed in the garb of truth!  Their supreme wisdom is supreme folly:  and they mistake for happiness the mere absence of pain.  Had they ever felt the solid pleasure of one generous spasm of the heart, they would exchange for it all the frigid speculations of their lives, which you have been vaunting in such elevated terms.  Believe me, then, my friend, that that is a miserable arithmetic, which could estimate friendship at nothing, or at less than nothing.  Respect for you has induced me to enter into this discussion, and to hear principles uttered, which I detest and abjure.  Respect for myself now obliges me to recall you into the proper limits of your office.  When nature assigned us the same habitation, she gave us over it a divided empire.  To you she allotted the field of science; to me that of morals.

When the circle is to be squared, or the orbit of a comet to be traced; when the arch of greatest strength, or the solid of least resistance is to be investigated, take up the problem; it is yours; nature has given me no cognizance of it.  In like manner, in denying to you the feelings of sympathy, of benevolence, of gratitude, of justice, of love, of friendship, she has excluded you from their control.  To these she has adapted the mechanism of the heart.  Morals were too essential to the happiness of man, to be risked on the uncertain combinations of the head.  She laid their foundation, therefore, in sentiment, not in science.  That she gave to all, as necessary to all:  this to a few only, as sufficing with a few.  I know indeed, that you pretend authority to the sovereign control of our conduct, in all its parts:  and a respect for your grave saws and maxims, a desire to do what is right, has sometimes induced me to conform to your counsels.  A few facts, however, which I can readily recall to your memory, will suffice to prove to you, that nature has not organized you for our moral direction.  When the poor wearied soldier, whom we overtook at Chickahominy, with his pack on his back, begged us to let him get up behind our chariot, you began to calculate that the road was full of soldiers, and that if all should be taken up, our horses would fail in their journey.  We drove on therefore.  But soon becoming sensible you had made me do wrong, that though we cannot relieve all the distressed, we should relieve as many as we can, I turned about to take up the soldier; but he had entered a by-path, and was no more to be found:  and from that moment to this, I could never find him out to ask his forgiveness.
