True love is like ghosts, which everyone talks about but few have seen.
There is no disguise which can hide love for long where it exists, or simulate it where it does not.
Absence diminishes mediocre passions and increases great ones, as the wind extinguishes candles and fans fires.
It never ceases to amaze me: we all love ourselves more than other people, but care more about their opinions than our own.
Fortunate is he who does not carry envy as a companion.
The man of knowledge must be able not only to love his enemies but also to hate his friends.
