Meditation 12.5
5. How was it that the gods, who ordered all things aright and with love to man, overlooked this one thing only, that among mortal men some altogether good, who had, so to speak, most commerce with the Godhead, and by holy acts and solemn rites had grown in the highest degree familiar with Him, should, once dead, never come into being again but be entirely extinguished?
Now, if indeed it is so, be certain of this that, if it ought to have been otherwise, the gods would have made it so; for were it just, it would also be possible, and were it accordant with Nature, Nature would have brought it about. Therefore from its not being so, if indeed it is not so, you should believe that it ought not to come to pass. For you yourself see that, by questioning thus, you are arguing a point of justice with God. Now we should not be debating thus with the gods unless they were most good and most just; and if this is true, they would not have permitted any part of the ordered world they govern to be unjustly and unreasonably neglected.
