The right to search for truth implies also a duty; one must not conceal any part of what one has recognized to be true.
Knowledge and skills alone cannot lead humanity to a happy and dignified life. Humanity has every reason to place the proclaimers of high moral standards and values above the discoverers of objective truth.

Be of good cheer about death, and know this of a truth, that no evil can happen to a good man, either in life or after death.
I desire only to know the truth, and to live as well as I can. And, to the utmost of my power, I exhort all other men to do the same. I exhort you also to take part in the great combat, which is the combat of life, and greater than every other earthly conflict.

We approach truth only inasmuch as we depart from life. For what do we, who love truth, strive after in life? To free ourselves from the body, and from all the evil that is caused by the life of the body! If so, then how can we fail to be glad when death comes to us? The wise man seeks death all his life and therefore death is not terrible to him.
He’s garbage, he cares about nothing but the truth.
