Purity of heart is to will one thing.

We are not naïve enough to ask for pure men; we ask merely for men whose impurity does not conflict with the obligations of their job.

Mud-pies gratify one of our first and best instincts. So long as we are dirty, we are pure.

The sick do not ask if the hand that smoothes their pillow is pure, nor the dying care if the lips that touch their brow have known the kiss of sin.
