Jean Gerson

The bigger problem is that you want to masturbate instead of having sex with your pr- partner, and that's what you should be focused on.

Okay? But a few late medieval manuals, like, um, Jean Gerson told priests how to ask about it.

And you should just also consider the Ten Commandments.

Masturbation's not on them.

Though theoretical theology and philosophy generally were conservative at Paris, yet here as well as elsewhere movements to reform the Church were not wanting.

The authority of Jean Gerson, the university's great chancellor about 1400, had not yet been forgotten, but reform by no means meant inclination to depart from the doctrine of the Church.

It aimed in the first place at restoration and purification of the monastic orders, and afterwards at the extermination of abuses which the Church acknowledged and lamented as existing within its fold.

In that spirit of reformation of spiritual life, the Dutch movement of Devotio Moderna had recently begun to make itself felt also at Paris.
