There are two salient things to which this quote could apply, and I somewhat endorse applying it to both of them :-)

You can’t prescribe decently for something you hate. It will always come out wrong. You can’t prescribe decently for something you despair in. If you despair of humankind, you’re not going to have good policies for nurturing human beings. I think people ought to give prescriptions who have ideas for improving things, ought to concentrate on the things that they love and that they want to nurture.
