Why are you a Theist?

[Angrboda]

When one is attempting to rebut an accusation that one's scholarship is inadequate, it's best not to resort to quotations of questionable authenticity, lest one be considered to have abetted that accusation.

It is quite easy to do an internet search and find that every quote site has Seneca listed as the author. Until you can provide a source stating that Seneca did not author that quote, you are being silly. All I can find of any relevance is that no one is certain from which of his works it could have possibly derived, that perhaps it was something of his that was undocumented.

You're asking me to prove a negative are you? Sorry friend, that's not how it works. Produce a source for the quote in Seneca or shut the fuck up.
