Letter to his daughter (1978)
Context: Life is a love affair. There is a romance with every beauty of nature. I have no hesitation in saving that my most passionate love affair, my most thrilling romance has been with the people. There is an indissoluble marriage between politics and the people. That is why "Man is a political animal" and the state a political theatre. I have been on this stage of the masters for over twenty tumultuous years. I believe I still have a role to play. I believe the people still want me on this stage, but if I have to bow out, I give you the gift of my feelings. You will fight the fight better than me. Your speeches will be more eloquent than my speeches. Your commitment equally total. There will be more youth and vitality in your struggle. Your deeds ill be more daring. I transmit to you the blessing to the most blessed mission. This is the only present I can give you on your birthdays.

The Tatler (1711–1714)
Context: There are many more shining qualities in the mind of man, but there is none so useful as discretion; it is this, indeed, which gives a value to all the rest, which sets them at work in their proper times and places, and turns them to the advantage of the person who is possessed of them. Without it, learning is pedantry, and wit impertinence; virtue itself looks like weakness; the best parts only qualify a man to be more sprightly in errors, and active to his own prejudice.
