Famous quotes containing the words systems, secure and/or operating:
“People stress the violence. That’s the smallest part of it. Football is brutal only from a distance. In the middle of it there’s a calm, a tranquility. The players accept pain. There’s a sense of order even at the end of a running play with bodies stewn everywhere. When the systems interlock, there’s a satisfaction to the game that can’t be duplicated. There’s a harmony.”
—Don Delillo (b. 1926)
“There is not to be found, in all history, any miracle attested by a sufficient number of men, of such unquestioned good sense, education, and learning, as to secure us against all delusion in themselves ... beyond all suspicion of any design to deceive others ... and at the same time attesting facts, performed in such a public manner, and in so celebrated a part of the world, as to render the detection unavoidable.”
—David Hume (1711–1776)
“I love meetings with suits. I live for meetings with suits. I love them because I know they had a really boring week and I walk in there with my orange velvet leggings and drop popcorn in my cleavage and then fish it out and eat it. I like that. I know I’m entertaining them and I know that they know. Obviously, the best meetings are with suits that are intelligent, because then things are operating on a whole other level.”
—Madonna [Madonna Louise Ciccione] (b. 1959)
