Liberty makes people unhappy

A people without superstition would be philosophical and philosophers will never obey. The people can be happy only if they are crushed, downtrodden, kept in chains.

[To Voltaire] Your first passion is love of humanity. That love blinds you. Love humanity, but you can only love it as it is. It is incapable of the benefits you would lavish upon it; and, giving them, you would only make it more unhappy and more wicked. Leave it the monster which devours it; the monster is dear to it. I never laughed so much as when I saw Don Quixote having a very hard time defending himself from the galley slaves to whom he had just magnanimously given their freedom.

Giacomo Casanova - History of my life (6, 10)

The kind of people Hamlet likes

Since my dear soul was mistress of her choice
And could of men distinguish her election
Hath sealed thee for herself; for thou hast been
As one in suff'ring all that suffers nothing
A man that fortune’s buffets and rewards
Hast ta'en with equal thanks. And blessed are those
Whose blood and judgment are so well co-meddled,
That they are not a pipe for Fortune’s finger,
To sound what stop she please. Give me that man
That is not passion’s slave, and I will wear him
In my heart’s core, ay, in my heart of heart,
As I do thee. -

William Shakespeare - Hamlet
(The New Oxford Shakespeare - The Complete Works, Modern Critical Edition)

(Ever since I’ve been a free agent in my choice of friends, I’ve chosen you because you take everything life hands you with calm acceptance, grateful for both good and bad. Blessed are those who mix emotion with reason in just the right proportion, making them strong enough to resist the whims of Lady Luck. Show me the person who’s master of his emotions, and I’ll put him close to my heart—in my heart of hearts—as I do you. [No Fear Shakespeare])
