I know a woman who possesses a restless and intelligent mind, interested in her own culture, and earnest to enjoy the highest possible advantages, and I meet her with pleasure as a natural person who not a little provokes me, and I suppose is stimulated in turn by myself.
 Henry David Thoreau, A Week on the Concord and Merrimack Rivers (1849). copy citation

Context

“If they know not of these things, how can they be informed? We often forbear to confess our feelings, not from pride, but for fear that we could not continue to love the one who required us to give such proof of our affection. I know a woman who possesses a restless and intelligent mind, interested in her own culture, and earnest to enjoy the highest possible advantages, and I meet her with pleasure as a natural person who not a little provokes me, and I suppose is stimulated in turn by myself. Yet our acquaintance plainly does not attain to that degree of confidence and sentiment which women, which all, in fact, covet. I am glad to help her, as I am helped by her; I like very well to know her with a sort of stranger’s privilege, and hesitate to visit her often, like her other Friends.” source
