Jeremy Bentham, The Panopticon Writings

"Happiness is a very pretty thing to feel, but very dry to talk about."

"Bodies are real entities. Surfaces and lines are but fictitious entities. A surface without depth, a line without thickness, was never seen by any man; no; nor can any conception be seriously formed of its existence."

"In the mind of all, fiction, in the logical sense, has been the coin of necessity;—in that of poets of amusement—in that of the priest and the lawyer of mischievous immorality in the shape of mischievous ambition,—and too often both priest and lawyer have framed or made in part this instrument."
