Alexander Graham Bell

I am a believer in unconscious cerebration. The brain is working all the time, though we do not know it. At night it follows up what we think in the daytime. When I have worked a long time on one thing, I make it a point to bring all the facts regarding it together before I retire; I have often been surprised at the results... We are thinking all the time; it is impossible not to think.

But often what the world calls nonsensical, becomes practical, does it not? You were called crazy, too, once, were you not?

The achievement of one goal should be the starting point of another.

Wherever you may find the inventor, you may give him wealth or you may take from him all that he has; and he will go on inventing. He can no more help inventing than he can help thinking or breathing.

I begin my work at about nine or ten o'clock in the evening and continue until four or five in the morning. Night is a more quiet time to work. It aids thought.

We should try ourselves to forget that they are deaf. We should try to teach them to forget that they are deaf.

The main object of the education of the deaf is to fit them to live in the world of a hearing-speaking people.

If it is not necessary, it is obviously not advisable, that deaf children should acquire, and use, as their ordinary and habitual means of communication — their vernacular in fact — a language that is not understood by the people among whom they live.

A man's own judgement should be the final appeal in all that relates to himself.

There are two critical points in every aerial flight - its beginning and its end.

Environment counts for a great deal. A man's particular idea may have no chance for growth or encouragement in his community. Real success is denied that man, until he finds a proper environment.

I had made up my mind to find that for which I was searching even if it required the remainder of my life. After innumerable failures I finally uncovered the principle for which I was searching, and I was astounded at its simplicity.

All really big discoveries are the results of thought.
