Letters 108.16

That is why I have also throughout my life avoided perfumes; because the best scent for the person is no scent at all. That is why my stomach is unacquainted with wine. That is why throughout my life I have shunned the bath, and have believed that to emaciate the body and sweat it into thinness is at once unprofitable and effeminate. Other resolutions have been broken, but after all in such a way that, in cases where I ceased to practice abstinence, I have observed a limit which is indeed next door to abstinence; perhaps it is even a little more difficult, because it is easier for the will to cut off certain things utterly than to use them with restraint.
