The only good is knowledge and the only evil is ignorance.

Knowledge becomes evil if the aim be not virtuous.

The real solution lies in a world in which charity will have become unnecessary.

Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it.

My alma mater was books, a good library.... I could spend the rest of my life reading, just satisfying my curiosity.

The first idea the child must acquire is that of the difference between good and evil.

To every action there is always an equal and opposite or contrary, reaction

We could never learn to be brave and patient, if there were only joy in the world

The most important part of teaching is to teach what it is to know.

Any sufficiently advanced technology is indistinguishable from magic.

Seek knowledge from the cradle to the grave.

Never help a child with a task at which he feels he can succeed.

Real learning comes about when the competitive spirit has ceased.

Investigate, educate and organize the country must progress, productive works and industries are the main avenues at present next to education for the advancement of the country

Books are for people who wish they were somewhere else.

Industrialize or perish.

No power and no treasure can outweigh the extension of our knowledge.

Make it a rule never to give a child a book you would not read yourself.

As we acquire more knowledge, things do not become more comprehensible but more mysterious.

It is not enough for the teacher to love the child. She must first love and understand the universe. She must prepare herself, and truly work at it.

Don't learn to do, but learn in doing.
