Famous quotes containing the words preventive and/or maintenance:
“General education is the best preventive of the evils now most dreaded. In the civilized countries of the world, the question is how to distribute most generally and equally the property of the world. As a rule, where education is most general the distribution of property is most general.... As knowledge spreads, wealth spreads. To diffuse knowledge is to diffuse wealth. To give all an equal chance to acquire knowledge is the best and surest way to give all an equal chance to acquire property.”
—Rutherford Birchard Hayes (1822–1893)
“My course is a firm assertion and maintenance of the rights of the colored people of the South according to the Thirteenth, Fourteenth, and Fifteenth Amendments, coupled with a readiness to recognize all Southern people, without regard to past political conduct, who will now go with me heartily and in good faith in support of these principles.”
—Rutherford Birchard Hayes (1822–1893)
