Plato says, that the
extremity of philosophy is hurtful, and advises not to dive into it
beyond the limits of profit; that, taken moderately, it is pleasant and
useful; but that in the end it renders a man brutish and vicious, a
contemner of religion and the common laws, an enemy to civil
conversation, and all human pleasures, incapable of all public
administration, unfit either to assist others or to relieve himself, and
a fit object for all sorts of injuries and affronts. He says true; for
in its excess, it enslaves our natural freedom, and by an impertinent
subtlety, leads us out of the fair and beaten way that nature has traced
for us.

The love we bear to our wives is very lawful, and yet theology thinks fit
to curb and restrain it. As I remember, I have read in one place of St.
Thomas Aquinas,--[Secunda Secundx, Quaest. 154, art. 9.]--where he
condemns marriages within any of the forbidden degrees, for this reason,
amongst others, that there is some danger, lest the friendship a man
bears to such a woman, should be immoderate; for if the conjugal
affection be full and perfect betwixt them, as it ought to be, and that
it be over and above surcharged with that of kindred too, there is no
doubt, but such an addition will carry the husband beyond the bounds of
reason.

Those sciences that regulate the manners of men, divinity and philosophy,
will have their say in everything; there is no action so private and
secret that can escape their inspection and jurisdiction. They are best
taught who are best able to control and curb their own liberty; women
expose their nudities as much as you will upon the account of pleasure,
though in the necessities of physic they are altogether as shy. I will,
therefore, in their behalf:

--[Coste translates this: "on the part of philosophy and theology,"
observing that but few wives would think themselves obliged to
Montaigne for any such lesson to their husbands.]--

teach the husbands, that is, such as are too vehement in the exercise of
the matrimonial duty--if such there still be--this lesson, that the very
pleasures they enjoy in the society of their wives are reproachable if
immoderate, and that a licentious and riotous abuse of them is a fault as
reprovable here as in illicit connections. Those immodest and debauched
tricks and postures, that the first ardour suggests to us in this affair,
are not only indecently but detrimentally practised upon our wives.
