Famous quotes containing the words families, common and/or origin:
“There is a city myth that country life was isolated and lonely; the truth is that farmers and their families then had a richer social life than they have now. They enjoyed a society organic, satisfying and whole, not mixed and thinned with the life of town, city and nation as it now is.”
—Rose Wilder Lane (1886–1965)
“A country is strong which consists of wealthy families, every member of whom is interested in defending a common treasure; it is weak when composed of scattered individuals, to whom it matters little whether they obey seven or one, a Russian or a Corsican, so long as each keeps his own plot of land, blind in their wretched egotism, to the fact that the day is coming when this too will be torn from them.”
—Honoré De Balzac (1799–1850)
“There are certain books in the world which every searcher for truth must know: the Bible, the Critique of Pure Reason, the Origin of Species, and Karl Marx’s Capital.”
—W.E.B. (William Edward Burghardt)
