Plato Apology 40

[40] I feel that you are my friends, and I wish to show you the meaning of this which has now happened to me. For, judges—and in calling you judges I give you your right name—a wonderful thing has happened to me. For hitherto the customary prophetic monitor always spoke to me very frequently and opposed me even in very small matters, if I was going to do anything I should not; but now, as you yourselves see, this thing which might be thought, and is generally considered, the greatest of evils has come upon me; but the divine sign did not oppose me 40b either when I left my home in the morning, or when I came here to the court, or at any point of my speech, when I was going to say anything; and yet on other occasions it stopped me at many points in the midst of a speech; but now, in this affair, it has not opposed me in anything I was doing or saying. What then do I suppose is the reason? I will tell you. This which has happened to me is doubtless a good thing, and those of us who think death is an evil 40c must be mistaken. A convincing proof of this been given me; for the accustomed sign would surely have opposed me if I had not been going to meet with something good.
  Let us consider in another way also how good reason there is to hope that it is a good thing. For the state of death is one of two things: either it is virtually nothingness, so that the dead has no consciousness of anything, or it is, as people say, a change and migration of the soul from this to another place. And if it is unconsciousness, 40d like a sleep in which the sleeper does not even dream, death would be a wonderful gain. For I think if any one were to pick out that night in which he slept a dreamless sleep and, comparing with it the other nights and days of his life, were to say, after due consideration, how many days and nights in his life had passed more pleasantly than that night,—I believe that not only any private person, but even the great King of Persia himself 40e would find that they were few in comparison with the other days and nights. So if such is the nature of death, I count it a gain; for in that case, all time seems to be no longer than one night. But on the other hand, if death is, as it were, a change of habitation from here to some other place, and if what we are told is true, that all the dead are there, what greater blessing could there be, judges?
