The rust of the mind is the blight of genius.
The only jewel which will not deday is knowledge.
The more understanding the fewer words.
The more a man knows the more he is inclined to be modest.
The learned man has always riches in himself.
The intellect engages us in the pursuit of truth, the passions impel us to action.
The greatest learning is to be seen in the greatest plainness.
The fountain of wisdom flows through books.
The first step to self-knowledge is self-distrust
The exception proves the rule.
The best blood by learning is refined.
Teaching others teaches yourself.
Take heed of the words of the wise.
Take heed of many, the advice of few.
Study makes learned men but not always pious and wise.
Something is learned every time a book is opened.
Search all things, hold fast that which is true.
Profess not the knowledge thou hast not.
One should make a study of pastime.
