- Hoist up sail while gale doth last, Tide and wind stay no man’s pleasure.
- Weak minds sink under prosperity as well as adversity; but strong and deep ones have two high tides.
- Happiness is not a matter of events; it depends upon the tides of the mind.
- Someday, after mastering the winds, the waves, the tides and gravity, we shall harness for God the energies of love, and then, for a second time in the history of the world, man will have discovered fire.
Pierre Teilhard de Chardin
