Carl Sagan on love

Imagination will often carry us to worlds that never were. But without it, we go nowhere.

Extraordinary claims require extraordinary proof.

We live in a society absolutely dependent on science and technology and yet have cleverly arranged things so that almost no one understands science and technology. That’s a clear prescription for disaster.

‘Tis better to have loved and lost / Than never to have loved at all.

Alfred, Lord Tennyson1809–1892In Memoriam A.H.H. (1850)In contextOften credited to Augustine of Hippo

If music be the food of love, play on.

William Shakespeare1564–1616Twelfth Night (1601), Act I, scene i.In context

• Music

Love anything and your heart will be wrung and possibly broken. If you want to make sure of keeping it intact you must give it to no one, not even an animal. Wrap it carefully round with hobbies and little luxuries; avoid all entanglements. Lock it up safe in the casket or coffin of your selfishness. But in that casket, safe, dark, motionless, airless, it will change. It will not be broken; it will become unbreakable, impenetrable, irredeemable. To love is to be vulnerable.

C. S. Lewis1898–1963The Four Loves (1960), Ch. VI: “Charity”
