I don't usually discuss 'famous lifetimes' because they don't often carry major life lessons for the famous person. Also, those souls who do famous lifetimes typically work out the remnants of that lifetime pretty swiftly--life has a sharp learning curve against the outcomes of those things.

However, in this case, I must to make an exception...

You are in a cell. It's not really a prison cell as we future folk would know it, more like a monk's cell. Sparse, with a single window you can see out of only if you climb onto the bed.

Part of your true heresy is burning outside that window. The stench of burning flesh mingle with the musty odor of dust and mildew inside the tiny cell.

Your great heresy wasn't disbelief. It was sharing that disbelief with too many people. You hoped for death, for you feared aging... but your true regret floated in the window as ash...

Some of your students are being burned. 'They' [the gov] knew that just killing you would not punish you. They knew that no amount of torture of your self would break your heart...

But your students. Your poor students. That, and that alone, could deeply break your heart, and the stench of their misery and their cries cannot be blocked out.

When they come with the poison, it is a relief. You escape the true torture outside your window, knowing that they will stop now. Having made their point, once your death has come, there will be no more point to their atrocity.

You drink it and you lie down. Your muscles grow weak at first, and you feel light-headed, almost peaceful. Tingles and then numbness fall over your body, creeping across your face. Eventually though, your lungs cease to function, and you begin to die of asphyxiation. You can't even struggle, and it is a horrifying and miserable death, screaming inside the sealed vault of your mind.

At last it is over.

If you have not already done so in this life, Socrates, I invite you to begin teaching again. It will be a great balm to your soul, for 'heresy' is the engine of the future, and without someone to teach it, there can be no one to learn it.
