That fidelity is impossible, at least to the man?

That an investigation if it could be undertaken would prove that in
the transmission of patrimonial property there was more risk than
security?

That adultery does more harm than marriage does good?

That infidelity in a woman may be traced back to the earliest ages of
society, and that marriage still survives this perpetuation of
treachery?

That the laws of love so strongly link together two human beings that
no human law can put them asunder?

That while there are marriages recorded on the public registers, there
are others over which nature herself has presided, and they have been
dictated either by the mutual memory of thought, or by an utter
difference of mental disposition, or by corporeal affinity in the
parties named; that it is thus that heaven and earth are constantly at
variance?

That there are many husbands fine in figure and of superior intellect
whose wives have lovers exceedingly ugly, insignificant in appearance
or stupid in mind?

All these questions furnish material for books; but the books have
been written and the questions are constantly reappearing.
