Famous quotes containing the words interesting and/or properties:
“Bolkenstein, a Minister, was speaking on the Dutch programme from London, and he said that they ought to make a collection of diaries and letters after the war. Of course, they all made a rush at my diary immediately. Just imagine how interesting it would be if I were to publish a romance of the “Secret Annexe.” The title alone would be enough to make people think it was a detective story.”

“The reason why men enter into society, is the preservation of their property; and the end why they choose and authorize a legislative, is, that there may be laws made, and rules set, as guards and fences to the properties of all the members of the society: to limit the power, and moderate the dominion, of every part and member of the society.”
—John Locke (1632–1704)
