Always tell the truth. It's the easiest thing to remember.

Always speak the truth, think before you speak, and write it down afterwards.

Always tell the Truth : where it is not loved, it is respected and feared.

Be conscious of God and speak always the truth,

When you tell the truth, you have nothing to keep track of. The world itself becomes your memory, and if questions arise, you can always point others back to it. You can even reconsider certain facts and honestly change your views. And you can openly discuss your confusion, conflicts, and doubts with all comers. A commitment to the truth is naturally purifying of error.

When writing about oneself, one must strive to be truthful. Truth is more important than modesty.

Why in fact should one tell the truth? What obliges us to do it? And why do we consider telling the truth to be a virtue? Imagine that you meet a madman, who claims that he is a fish and that we are all fish. Are you going to argue with him? Are you going to undress in front of him and show him that you don't have fins? Are you going to say to his face what you think?...If you told him the whole truth and nothing but the truth, only what you thought, you would enter into a serious conversation with a madman and you yourself would become mad. And it is the same way with the world that surrounds us. If I obstinately told the truth to its face, it would mean that I was taking it seriously. And to take seriously something so unserious means to lose all one's own seriousness. I have to lie, if I don't want to take madmen seriously and become a madman myself.

When in doubt tell the truth. It will confound your enemies and astound your friends.

While it is good to speak well, it is better to speak the truth.

It is always the best policy to speak the truth, unless, of course, you are an exceptionally good liar.

As you grow up, always tell the truth, do no harm to others, and don't think you are the most important being on earth. Rich or poor, you then can look anyone in the eye and say, 'I'm probably no better than you, but I'm certainly your equal.

Always be truthful and you will have fewer visits from regret, guilt or fear.

When you want to help people, you tell them the truth. When you want to help yourself, you tell them what they want to hear.

In Paradise, everyone speaks the truth. That is what makes it Paradise. Tell the truth. Or, at least, don’t lie.
