Famous quotes containing the words physical and/or properties:
“The preservation of health is a duty. Few seem conscious that there is such a thing as physical morality.”
—Herbert Spencer (1820–1903)
“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)
