Famous quotes containing the word supported:

    “Our thoughts are always elsewhere; we are stayed and supported by the hope for a better life, or by the hope that our children will turn out well, or that our name will be famous in the future, or that we shall escape the evils of this life, or that vengeance threatens those who are the cause of our death.”
    —Michel de Montaigne (1533–1592)
