“In general I ask for books that make use of learning, not those that build it up.”

“To compensate a little for the treachery and weakness of my memory, so extreme that it has happened to me more than once to pick up again...books which I have read carefully a few years before. I have adopted the habit for some time now of adding at the end of each book the time I finished reading it and the judgment I have derived of it as a whole, so that this may represent to me at least the sense and general idea I had conceived of the author in reading it.”

“Would I fortify myself against the fear of death, it must be at the expense of Seneca: would I extract consolation for myself or my friend, I must borrow it from Cicero.  I might have found it in myself, had I been trained to make use of my own reason.  I do not like this relative and mendicant understanding; for though we could become learned by other men's learning, a man can never be wise but by his own wisdom.”

“In truth, knowledge is a great and very useful quality; those who despise it give evidence enough of their stupidity. Yet I do not set its value at that extreme measure that some attribute to it, such as the philosopher Herillus, who find in it the sovereign good and think it has the power to make us wise and happy.”

“~The value of life lies not in the length of days, but in the use we make of them ~”

“To compose our character is our duty, not to compose books, and to win, not battles and provinces, but order and tranquility in our conduct. Our great and glorious masterpiece is to live appropriately. All other things, ruling, hoarding, building, are only little appendages and props, at most.”

“All we do is to look after the opinions and learning of others: we ought to make them our own.”
