“Nothing is more dangerous than solitude.”

I laugh at my heart, and do its will.

You can easily judge the character of a man by how he treats those who can do nothing for him.

None are more hopelessly enslaved than those who falsely believe they are free.

All that is transitory is but a metaphor.

I love those who yearn for the impossible.

There are two things children should get from their parents: roots and wings.

Two souls, alas, are housed within my breast, and each will wrestle for the mastery there.

Knowing is not enough; we must apply. Willing is not enough; we must do.

We know accurately only when we know little; doubt grows with knowledge.

One ought, every day at least, to hear a little song, read a good poem, see a fine picture, and, if it were possible, to speak a few reasonable words.

There is no past we can bring back by longing for it. There is only an eternal now that builds and creates out of the past something new and better.

The intelligent man finds everything laughable, the sensible man hardly anything.

The suffering may be moral or physical; and in my opinion it is just as absurd to call a man a coward who destroys himself, as to call a man a coward who dies of a malignant fever.

Doubt can only be removed by action.

There is nothing worse than aggressive stupidity.

Daring ideas are like chessmen moved forward. They may be beaten, but they may start a winning game.

The bravest are surely those who have the clearest vision of what is before them, glory and danger alike, and yet notwithstanding go out to meet it.

The most dangerous drug I know has brown eyes and a heartbeat.

In extreme danger fear feels no pity.

It’s fun to be hopelessly in love. It’s dangerous, but it’s fun.

For a man’s counsel cannot have equal weight or worth, when he alone has no children to risk in the general danger.

Danger doesn’t always come from the enemy.

Jails and prisons are designed to break human beings, to convert the population into specimens in a zoo – obedient to our keepers, but dangerous to each other.

No one that encounters prosperity does not also encounter danger.
