Famous quotes containing the words material and/or properties:
“Appalling is the soul of a man! Better might one be pushed off into the material spaces beyond the uttermost orbit of our sun, than once feel himself fairly afloat in himself.”
—Herman Melville (1819–1891)
“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)
