There are plenty of thoughtful quotes. I loved this one:
To tell the truth is to bring the most habitable
reality into Being. Truth builds edifices that
can stand a thousand years. Truth feeds and
clothes the poor, and makes nations wealthy
and safe. Truth reduces the terrible
complexity of a man to the simplicity of his
word, so that he can become a partner rather
than an enemy. Truth makes the past truly
past, and makes the best use of the future's
possibilities. Truth is the ultimate,
inexhaustible natural resource. It's the light in the darkness.
See the truth. Tell the truth.
