“There are three classes of people: those who see. Those who see when they are shown. Those who do not see.”

“I abhor the supreme folly of those who blame the disciples of nature in defiance of those masters who were themselves her pupils”

“Time stays long enough for those who use it.”

“Those who, in debate, appeal to their qualifications, argue from memory, not from understanding.”

“I love those who can smile in trouble, who can gather strength from distress, and grow brave by reflection. 'Tis the business of little minds to shrink, but they whose heart is firm, and whose conscience approves their conduct, will pursue their principles unto death”

“Why does the eye see more clearly when asleep than the imagination when awake?”

“He who can copy can do.”
