I found the best quote for my paper on insanity:

"For those whom God to ruin designed. He fits for fate, and first destroys their mind."
-John Dryden

I also like this Oscar Wilde quote about selfishness but I'm not sure it quite works with my paper on selfishness, but it's cute:

"A red rose is not selfish because it wants to be a red rose. It would be horribly selfish if it wanted all the other flowers in the garden to be both red and roses."

I've lastly been looking at quotes for my Health care debate paper and I've found a couple (but I'm not convinced about using any of them yet):

“Government's first duty is to protect the people, not run their lives.”
-Ronald Reagan

"The shepherd drives the wolf from the sheep's throat, for which the sheep thanks the shepherd as his liberator, while the wolf denounces him for the same act, as the destroyer of liberty. Plainly the sheep and the wolf are not agreed upon a definition of the word liberty; and precisely the same difference prevails today among human creatures."
- Abraham Lincoln

"I am going to screw the country, redistribute wealth, destroy the nation's healthcare system, and go around apologizing for everything that America has accomplished in the last 200 years".
-BHO
