For having lived long, I have experienced many instances of being obliged, by better information or fuller consideration, to change opinions, even on important subjects, which I once thought right but found to be otherwise.

How few there are who have courage enough to own their faults, or resolution enough to mend them.

I saw few die of hunger of eating, a hundred thousand.

In this world nothing can be said to be certain, except death and taxes.

I look upon death to be as necessary to our constitution as sleep. We shall rise refreshed in the morning.
