Our passions are the true phoenixes; when the old one is burnt out, a new one rises from its ashes. – Johann Wolfgang von Goethe

Passion, though a bad regulator, is a powerful spring. – Ralph Waldo Emerson

For passion has come to the verge and leaps headlong to the blind abyss, yet gathers thereby the strength of deeps, and eddies a moment and swirls and sweeps till peril is one with bliss! – Harriet L. Childe Pemberton

But this had been a sin of passion, not of principle, nor even purpose. – Nathaniel Hawthorne, The Scarlet Letter
