It must always be borne in mind that the assumption of woman's social superiority lies at the root of these rules of conduct.

Nothing is so dangerous to the progress of the human mind than to assume that our views of science are ultimate, that there are no mysteries in nature, that our triumphs are complete and that there are no new worlds to conquer.

Cuvier had even in his address & manner the character of a superior Man, much general power & eloquence in conversation & great variety of information on scientific as well as popular subjects. I should say of him that he is the most distinguished man of talents I have ever known on the continent: but I doubt if He be entitled to the appellation of a Man of Genius.

Fortunately science, like that nature to which it belongs, is neither limited by time nor by space. It belongs to the world, and is of no country and no age. The more we know, the more we feel our ignorance; the more we feel how much remains unknown.

What is politeness in the home but the outcome of affection and self-respect, and the suppression of all those natural instincts of self-seeking that, allowed their way, produce the worst manners in the world?

Nothing tends so much to the advancement of knowledge as the application of a new instrument. The native intellectual powers of men in different times are not so much the causes of the different success of their labours, as the peculiar nature of the means and artificial resources in their possession.

Profound minds are the most likely to think lightly of the resources of human reason, and it is the superficial thinker who is generally strongest in every kind of unbelief.
