More quotes by Alexander Graham Bell
Leave the beaten track behind occasionally and dive into the woods. Every time you do you will be certain to find something you have never seen before.
Alexander Graham Bell
I have had the feeling that a properly constructed flying-machine should be capable of being flown as a kite and conversely, that a properly constructed kite should be capable of use as a flying-machine when driven by its own propellers.
Alexander Graham Bell
I have heard articulate speech produced by sunlight I have heard a ray of the sun laugh and cough and sing! … I have been able to hear a shadow, and I have even perceived by ear the passage of a cloud across the sun's disk.
Alexander Graham Bell

Alexander Graham Bell
What this power is I cannot say all I know is that it exists and it becomes available only when a man is in that state of mind in which he knows exactly what he wants and is fully determined not to quit until he finds it.
Alexander Graham Bell

Alexander Graham Bell
There are two critical points in every aerial flight-its beginning and its end.
Alexander Graham Bell
With every door that closes a new one opens.
Alexander Graham Bell
Sometimes we stare so long at a door that is closing that we see too late the one that is open.
Alexander Graham Bell
Man is an animal which, alone among the animals, refuses to be satisfied by the fulfillment of animal desires.
Alexander Graham Bell
Grand telegraphic discovery today … Transmitted vocal sounds for the first time ... With some further modification I hope we may be enabled to distinguish … the “timbre” of the sound. Should this be so, conversation viva voce by telegraph will be a fait accompli.
Alexander Graham Bell
Night is a more quiet time to work. It aids thought.
Alexander Graham Bell
One day every major city in America will have a telephone.
Alexander Graham Bell
Leave the beaten track behind occasionally and dive into the woods.
Alexander Graham Bell
Don't keep forever on the public road, going only where others have gone and following one after the other like a flock of sheep. Leave the beaten track occasionally and dive into the woods.
Alexander Graham Bell
We are all too much inclined, I think, to walk through life with our eyes shut. There are things all round us and right at our very feet that we have never seen, because we have never really looked.
Alexander Graham Bell
God has strewn our paths with wonders and we certainly should not go through life with our eyes shut
