Times are bad. Children no longer obey their parents, and everyone is writing a book. — Marcus Tullius Cicero. Roman statesman and lawyer (106–43 BC) Writing
For no phase of life, whether public or private, whether in business or in the home, whether one is working on what concerns oneself alone or dealing with another, can be without its moral duty; on the discharge of such duties depends all that is morally right, and on their neglect all that is morally wrong in life.
Wise men are instructed by reason; men of less understanding, by experience; the most ignorant, by necessity; the beasts, by nature.
