Famous quotes containing the words proposed and/or explanations:

    “There is no legislation—I care not what it is—tariff, railroads, corporations, or of a general political character, that all equals in importance the putting of our banking and currency system on the sound basis proposed in the National Monetary Commission plan.”
    —William Howard Taft (1857–1930)

    “Young children constantly invent new explanations to account for complex processes. And since their inventions change from week to week, furnishing the “correct” explanation is not quite so important as conveying a willingness to discuss the subject. Become an “askable parent.””
    —Ruth Formanek (20th century)
