Echoes

They are ill discoverers that think there is no land, when they can see nothing but sea.

The most dangerous worldview is the worldview of those who have not viewed the world.

Stubborn and ardent clinging to one's opinion is the best proof of stupidity.

If your mind is empty, it is always ready for anything, it is open to everything.

Stay Hungry. Stay Foolish.

He who lives sees much. He who travels sees more.

Every generation has the obligation to free men's minds for a look at new worlds… to look out from a higher plateau than the last generation.

The world will hardly admit of an excuse for a man leaving a coast unexplored he has once discovered.

Wonder is the beginning of wisdom.

Travel is fatal to prejudice, bigotry, and narrow-mindedness.

If you want to improve, be content to be thought foolish and stupid.

A wise man gets more use from his enemies than a fool from his friends.

Not-knowing is true knowledge. Presuming to know is a disease.

The sun is new each day.

Men who have made these discoveries before us are not our masters, but our guides.

Genius, in truth, means little more than the faculty of perceiving in an unhabitual way.

The greater the ignorance the greater the dogmatism.

He who knows all the answers has not been asked all the questions.

People often say that I'm curious about too many things at once. But can you really forbid a man from harboring a desire to know and embrace everything that surrounds him?

It isn't all over; everything has not been invented; the human adventure is just beginning.

I do not speak the minds of others except to speak my own mind better.

The pessimist sees difficulty in every opportunity. The optimist sees opportunity in every difficulty.
