To the natural philosopher, there is no natural object unimportant or trifling. From the least of Nature's works he may learn the greatest lessons.

No doubt the testimony of natural reason, on whatever exercised, must, of necessity, stop short of those truths which it is the object of revelation to make known; still it places the existence and personal attributes of the Deity on such grounds as to render doubts absurd and atheism ridiculous.

Occurrences which according to received theories ought not to happen, are the facts which serve as clues to new discoveries

There is a gentle, but perfectly irresistible coercion in a habit of reading well directed, over the whole tenor of a man's character and conduct, which is not the less effectual because it works insensibly, and because it is really the last thing he dreams of.

Johann Wolfgang von Goethe

Self-respect is the cornerstone of all virtue.

Self-respect,--the corner-stone of all virtue.
