“Nothing troubled the charm and silence of this solitude. Making the most serious reflections on what we behold, and on our present position, I said to myself: Thus does life also pass away, now calm, now agitated, but at last the end is attained. Happy, ah, thrice happy they who can then look out to the never-ending future with calm and confidence, who can cast themselves on the bosom of God, the Center of our felicity.”

The Siege of Valencia (1823), scene ix, reported in Bartlett's Familiar Quotations, 10th ed. (1919).

Cassandra (1860)
Context: Society triumphs over many. They wish to regenerate the world with their institutions, with their moral philosophy, with their love. Then they sink to living from breakfast till dinner, from dinner till tea, with a little worsted work, and to looking forward to nothing but bed.
When shall we see a life full of steady enthusiasm, walking straight to its aim, flying home, as that bird is now, against the wind — with the calmness and the confidence of one who knows the laws of God and can apply them?
