History says, don’t hope

 On this side of the grave.
 But then, once in a lifetime
 The longed-for tidal wave
 Of justice can rise up,
 And hope and history rhyme.--Seamus Heaney ("The Cure at Troy")

Hold your head high, stick your chest out. You can make it. It gets dark sometimes, but morning comes.... Keep hope alive.--Jesse Jackson

Hope and possibility best describe the art of teaching.--Camille Banks Lee (from The Quotable Teacher, comp. by Howe)

Hope arouses, as nothing else can arouse, a passion for the possible.--William Sloan Coffin, Jr.
