Book Three, Chapter 11
That the Desires of our Heart are to be Examined and Moderated

For not every inclination which appears good is therefore at once to be followed; nor is every contrary affection at once to be rejected.  Even in good intentions and desires it is expedient sometimes to use some restraint...Sometimes, indeed, we must use violence and manfully resist the sensual appetite, and not regard what the flesh likes or dislikes, but rather endeavor that, even against its will, it may be subject to the spirit.
