“Women are never tired of bewailing man’s fickleness in love, but they only seem to snub his constancy.”

“The fickleness of the women I love is only equaled by the infernal constancy of the women who love me.”

“My Lady, you certainly tell me about wonderful constancy, strength and virtue and firmness of women, so can one say the same thing about men? (...)Response [by Lady Rectitude]: "Fair sweet friend, have you not yet heard the saying that the fool sees well enough a small cut in the face of his neighbour, but he disregards the great gaping one above his own eye? I will show you the great contradiction in what the men say about the changeability and inconstancy of women. It is true that they all generally insist that women are very frail [= fickle] by nature. And since they accuse women of frailty, one would suppose that they themselves take care to maintain a reputation for constancy, or at the very least, that the women are indeed less so than they are themselves. And yet, it is obvious that they demand of women greater constancy than they themselves have, for they who claim to be of this strong and noble condition cannot refrain from a whole number of very great defects and sins, and not out of ignorance, either, but out of pure malice, knowing well how badly they are misbehaving. But all this they excuse in themselves and say that it is in the nature of man to sin, yet if it so happens that any women stray into any misdeed (of which they themselves are the cause by their great power and longhandedness), then it's suddenly all frailty and inconstancy, they claim. But it seems to me that since they do call women frail, they should not support that frailty, and not ascribe to them as a great crime what in themselves they merely consider a little defect.”

“Loving God alone, we unify our nature in single constancy; God himself kindles a love that burns but never consumes.”

“Constancy in love is a good thing; but it means nothing, and is nothing, without constancy in every kind of effort.”

“Man’s needs change, but not his love, nor his desire that his love should satisfy his needs.”
