Political liberty, the tranquility of a nation, nay, knowledge itself, are gifts on which destiny has laid a tax of blood!
Honor de Balzac
The tranquility and peace that a scholar needs is something as sweet and exhilarating as love. Unspeakable joys are showered on us by the exertion of our mental faculties; the quest of ideas, and the tranquil contemplation of knowledge; delights indescribable, because purely intellectual and impalpable to our senses.
Honor de Balzac
