I've yet to watch Continuum and though I like time travel and parallel worlds stories, as I read Charlie Jane's recap and many of the comments, I couldn't help but to think about how I really don't believe in such things.
Heresy on ObservationDeck and io9, I know, but I've never been able to rationalize it or come up with any logical method which would make time travel possible because I really think of time as a linear thing, plus nobody from the future or the past has ever contacted me or anyone that I know.
Because I had a few minutes to kill, I pulled up the Wikipedia on time travel and learned that one of the first examples of backwards time travel in literature was a 1733 work by Samuel "Premium" Madden which were a series of letters written in 1998 and carried back to 1728 by a guardian angel, Memoirs of the Twentieth Century.
This prompted me to look for a digital public domain copy, something I actually do from time to time and how I've read some really interesting books, especially non-fiction journal things from the 18th and 19th century, but for some reason this morning, I decided that reading this particular book would require too much effort for too little payoff. Wikipedia says it was originally envisioned as a six volume collection, but possibly because it was suppressed by the person considered Britain's first Prime Minister and the one who accepted 10 Downing Street from the king, Sir Robert Walpole, publication stopped at volume one.
Of course, now we have to wonder if Madden's "guardian angel" looked like one of these guys;
In case anyone is interested and where I can test the embed, the following is where I left off reading Memoirs, so I don't really know how accurate its vision of 1998 might have been.
Instead of slight, I guess his disappointment was great.
