What may not be expected in a country of eternal light - Mary Wollstonecraft Shelley

An ardent affection for the human race makes enthusiastic characters eager to produce alteration in laws and governments prematurely. To render them useful and permanent, they must be the growth of each particular soil, and the gradual fruit of the ripening understanding of the nation, matured by time, not forced by an unnatural fermentation.

"Of what a strange nature is knowledge! It clings to a mind when it has once seized on it like a lichen on a rock."
- Frankenstein p115

A human being in perfection ought always to preserve a calm and peaceful mind and never to allow passion or a transitory desire to disturb his tranquility. I do not think that the pursuit of knowledge is an exception to this rule. If the study to which you apply yourself has a tendency to weaken your affections and to destroy your taste for those simple pleasures in which no alloy can possibly mix, then that study is certainly unlawful, that is to say, not befitting the human mind. If this rule were always observed; if no man allowed any pursuit whatsoever to interfere with the tranquillity of his domestic affections, Greece had not been enslaved, Caesar would have spared his country, America would have been discovered more gradually, and the empires of Mexico and Peru had not been destroyed.
