Nolite te bastardes carborundorum. - Margaret Atwood

Being able to read and write did not provide answers to all questions. It led to other questions, and then to others.

Why is it we want so badly to memorialize ourselves? Even while we're still alive. We wish to assert our existence, like dogs peeing on fire hydrants. We put on display our framed photographs, our parchment diplomas, our silver-plated cups; we monogram our linen, we carve our names on trees, we scrawl them on washroom walls. It's all the same impulse. What do we hope from it? Applause, envy, respect? Or simply attention, of any kind we can get?
At the very least we want a witness. We can't stand the idea of our own voices falling silent finally, like a radio running down.

Extreme good, extreme evil: the abilities required are similar.
