You'll never believe who said this!

I love studing history! Just today, I came across these comments from a historical figure who lived in the 18th century. I'd love to see some guesses as to who penned these thoughts. I'll post the answer in a day or two.

I firmly believe it requires but a little philosophy to make a man happy in whatsoever state he is. This consists in a full resignation to the will of Providence, and a resigned soul finds pleasure in a path strewed with briers and thorns.

Need another clue? Here's one more quote:

"In this situation I was constantly exposed to danger and death. How unhappy such a situation for a man tormented with fear, which is vain if no danger comes, and if it does, only augments the pain! It was my happiness to be destitute of this afflicting passion, with which I had the greatest reason to be affected. The prowling wolves diverted my nocturnal hours with perpetual howlings, and the various species of animals in this vast forest, in the daytime, were continually in my view."

Happy guessing!

P.S. How do I get back to the left margin? Everytime I do a block quote, it's indented more than the last time. Help!
