“Romance and poetry, ivy, lichens and wallflowers need ruin to make them grow.”
Preface
The Marble Faun (1860)
Context: No author, without a trial, can conceive of the difficulty of writing a romance about a country where there is no shadow, no antiquity, no mystery, no picturesque and gloomy wrong, nor anything but a commonplace prosperity, in broad and simple daylight, as is happily the case with my dear native land. It will be very long, I trust, before romance writers may find congenial and easily handled themes, either in the annals of our stalwart republic, or in any characteristic and probable events of our individual lives. Romance and poetry, ivy, lichens and wallflowers need ruin to make them grow.

“LOVE is to stop making demands on people and give them room to grow.”

“The trick is growing up without growing old.”

“People come, people go.
Some grow young, some grow cold.”
