I know nothing but the certainty of my own ignorance.

You too must be of good hope as regards death, gentlemen of the jury, and keep this one truth in mind, that a good man cannot be harmed either in life or in death, and that his affairs are not neglected by the gods. What has happened to me now has not happened of itself, but it is clear to me that it was better for me to die now and to escape from trouble. That is why my divine sign did not oppose me at any point. So I am certainly not angry with those who convicted me, or with my accusers. Of course that was not their purpose when they accused and convicted me, but they thought they were hurting me, and for this they deserve blame.

I am confident that there truly is such a thing as living again, that the living spring from the dead, and that the souls of the dead are in existence.

Athletics have become professionalized.

Nothing very new. By taking good care of yourselves you are of service to me and my family as well as yourselves, no matter what you do, even if you don't think so at present. But if you neglect yourselves and are unwilling to live, as though following tracks, in accordance with what we now say and have said in the past too, then no matter how much or how seriously you agree with me at present you will accomplish next to nothing.

All thinking begins with wondering

Well I am certainly wiser than this man. It is only too likely that neither of us has any knowledge to boast of; but he thinks that he knows something which he does not know, whereas I am quite conscious of my ignorance. At any rate it seems that I am wiser than he is to this small extent, that I do not think that I know what I do not know.
