"The fourth (of the four cardinal virtues)..." - Quote by Lao Tzu
The fourth (of the four cardinal virtues) is supportiveness: this manifests as service to others without expectation of reward. (Paraphrased: Such service is not a mere conforming to some external rule of behavior, but instead a manifestation of your original nature).

“He is a truly virtuous man who wishes always to be open to the observation of honest men.”
“A strict observance of the written laws is doubtless one of the highest virtues of a good citizen, but it is not the highest. The laws of necessity, of self-preservation, of saving our country when in danger, are of higher obligation. To lose our country by a scrupulous adherence to written law would be to lose the law itself, with life, liberty, property and all those who are enjoying them with us; thus absurdly sacrificing the end to the means.”
“Passions are vices or virtues to their highest powers.”

“You don't want modesty, you want humility. Humility comes from inside out. It says someone was here before me and I'm here because I've been paid for. I have something to do and I will do that because I'm paying for someone else who has yet to come.”
“Although we are never glad when tragedy visits, we can be aware and seize the opportunity to do good in this world, even in the midst of tragedy.”
“To move forward you have to give back.”
