“The acquisitions he has made are such that we can say the child who enters school at three is an old man.”

Noble ideas, great sentiments have always existed and have always been transmitted, but wars have never ceased.

The only language men ever speak perfectly is the one they learn in babyhood, when no one can teach them anything!

The child who concentrates is immensely happy.

The possibility of observing the developments of the psychical life of the child as natural phenomena and experimental reactions transforms the school itself in action into a kind of scientific laboratory for the psychogenetic study of man.

We are not created only to enjoy the world, we are created in order to evolve the cosmos.

The greatest development is achieved during the first years of life, and therefore it is then that the greatest care should be taken. If this is done, then the child does not become a burden; he will reveal himself as the greatest marvel of nature.

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

The Iranian acquisition of nuclear weapons would be infinitely more costly than any scenario you can imagine to stop it.

That means at times we’ll develop new categories like we did with Surface. It also means we will responsibly make the market for Windows Phone, which is our goal with the Nokia devices and services acquisition.

Science is not a body of knowledge or a belief system, it is just a term that describes humankind’s incremental acquisition of understanding through observation.

Happiness is not an acquisition – it is a skill. We do not experience happiness because of what we get. We experience happiness because of how we live each moment.

Science is not a body of knowledge nor a system of belief.

The best part of writing is not the communication of knowledge to other people, but the acquisition and synthesizing of knowledge for oneself.
