Man is the result of slow growth; that is why he occupies the position he does in animal life. What does a pup amount to that has gained its growth in a few days or weeks, beside a man who only attains it in as many years.

Fleets are not confined to the ocean, but now sail over the land. … All the power of the British Navy has not been able to prevent Zeppelins from reaching England and attacking London, the very heart of the British Empire. Navies do not protect against aerial attack. … Heavier-than-air flying machines of the aeroplane type have crossed right over the heads of armies, of million of men, armed with the most modern weapons of destruction, and have raided places in the rear. Armies do not protect against aerial war.

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
Postscript (P.S.) on page 3 of letter to Sarah Fuller (1 Jul 1875). Bell Papers, Library of Congress.
Science quotes on:  |  Telephone (21)

Great discoveries and improvements invariably involve the cooperation of many minds. I may be given credit for having blazed the trail but when I look at the subsequent developments I feel the credit is due to others rather than to myself
— 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.
— Alexander Graham Bell
In Orison Swett Marden, 'Bell Telephone Talk: Hints on Success by Alexander G. Bell', How They Succeeded: Life Stories of Successful Men Told by Themselves (1901), 33.

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.

I feel that I have at last struck the solution of a great problem—and the day is coming when telegraph wires will be laid on to houses just like water or gas—and friends converse with each other without leaving home.
— Alexander Graham Bell
Letter (10 Mar 1876) to his father on the day his first words were sent by wire to Mr. Watson. As quoted in Robert V. Bruce, Bell: Alexander Graham Bell and the Conquest of Solitude (1973, 1990), 181.

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. I was still more astounded to discover the principle I had revealed not only beneficial in the construction of a mechanical hearing aid but it served as well as means of sending the sound of the voice over a wire. Another discovery which came out of my investigation was the fact that when a man gives his order to produce a definite result and stands by that order it seems to have the effect of giving him what might be termed a second sight which enables him to see right through ordinary problems. 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
As quoted, without citation, in Mack R. Douglas, Making a Habit of Success: How to Make a Habit of Succeeding, How to Win With High Self-Esteem (1966, 1994), 38. Note: Webmaster is dubious of a quote which seems to appear in only one source, without a citation, decades after Bell’s death. If you know a primary source, please contact Webmaster.

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
Letter to his father (26 Feb 1880), describing his photophone research. Transcript with Bell Papers, Library of Congress.

I have read somewhere that the resistance offered by a wire ... is affected by the tension of the wire. If this is so, a continuous current of electricity passed through a vibrating wire should meet with a varying resistance, and hence a pulsatory action should be induced in the current ... [corresponding] in amplitude, as well as in rate of movement, to the vibrations of the string ... [Thus] the timbre of a sound [a quality essential to intelligible speech] could be transmitted ... [and] the strength of the current can be increased ad libitum without destroying the relative intensities of the vibrations.
— Alexander Graham Bell
Letter to Gardiner Greene Hubbard (4 May 1875), 3-4. Bell Papers, Library of Congress.
Science quotes on:  |  Current (43)  |  Electricity (121)  |  Telephone (21)

I then shouted into M [the mouthpiece] the following sentence: “Mr. Watson—Come here—I want to see you.” To my delight he came and declared that he had heard and understood what I said. I asked him to repeat the words. He answered “You said—‘Mr. Watson—-come here—I want to see you.’” We then changed places and I listened at S [the reed receiver] while Mr. Watson read a few passages from a book into the mouth piece M. It was certainly the case that articulate sounds proceeded from S. The effect was loud but indistinct and muffled. If I had read beforehand the passage given by Mr. Watson I should have recognized every word. As it was I could not make out the sense—but an occasional word here and there was quite distinct. I made out “to” and “out” and “further”; and finally the sentence “Mr. Bell do you understand what I say? Do—you—un—der—stand—what—I—say” came quite clearly and intelligibly. No sound was audible when the armature S was removed.

If a man is not bound down, he is sure to succeed.
— Alexander Graham Bell
In Orison Swett Marden, 'Bell Telephone Talk: Hints on Success by Alexander G. Bell', How They Succeeded: Life Stories of Successful Men Told by Themselves (1901), 36.
Science quotes on:  |  Bound (12)  |  Success (202)

Leave the beaten track occasionally and dive into the woods. Every time you do so you will be certain to find something that you have never seen before. Of course, it will be a little thing, but do not ignore it. Follow it up, explore all around it: one discovery will lead to another, and before you know it, you will have something worth thinking about to occupy your mind. All really big discoveries are the results of thought.
— Alexander Graham Bell

Neither the Army nor the Navy is of any protection, or very slight protection, against aerial raids. We may therefore look forward with certainty to the time that is coming, and indeed is almost now at hand, when sea power and land power will be secondary to air power, and that nation which gains control of the air will practically control the world.
— Alexander Graham Bell

Perseverance is the chief, but perseverance must have some practical end, or it does not avail the man possessing it. A person without a practical end in view becomes a crank or an idiot. Such persons fill our asylums.
— Alexander Graham Bell
In Orison Swett Marden, 'Bell Telephone Talk: Hints on Success by Alexander G. Bell', How They Succeeded: Life Stories of Successful Men Told by Themselves (1901), 32.

The final result of our researches has widened the class of substances sensitive to light vibrations, until we can propound the fact of such sensitiveness being a general property of all matter.
— Alexander Graham Bell
In Paper (27 Aug 1880) read to the American Association for the Advancement of Science, 'On the Production and Reproduction of Sound by Light'. Printed in The American Journal of Science (Oct 1880), 20, 3rd Ser., No. 118, 305.

The inventor is a man who looks upon the world and is not contented with things as they are. He wants to improve whatever he sees, he wants to benefit the world; he is haunted by an idea. The spirit of invention possesses him, seeking materialization.
— Alexander Graham Bell
From Speech to the Patent Congress (1891) in Washington, D.C., as quoted in Jean Lesage, 'Alexander Graham Bell Museum: Tribute to Genius', The National Geographic Magazine (Aug 1956), 110, No. 2, 232. The article notes that this statement is “prominently displayed near the foyer” of the Canadian museum opened that month to memorialize Bell, in Baddeck, Nova Scotia.

The most successful men in the end are those whose success is the result of steady accretion. That intellectuality is more vigorous that has attained its strength gradually. It is the man who carefully advances step by step, with his mind becoming wider and wider—and progressively better able to grasp any theme or situation—persevering in what he knows to be practical, and concentrating his thought upon it, who is bound to succeed in the greatest degree.

There cannot be mental atrophy in any person who continues to observe, to remember what he observes, and to seek answers for his unceasing hows and whys about things.
— Alexander Graham Bell

Watson, if I can get a mechanism which will make a current of electricity vary in its intensity, as the air varies in density when a sound is passing through it, I can telegraph any sound, even the sound of speech.
— Alexander Graham Bell
As quoted by Thomas A. Watson, in Exploring Life: The Autobiography of Thomas A. Watson (1926), 62.
Science quotes on:  |  Electricity (121)  |  Telephone (21)

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. Inventors are born, not made.
— Alexander Graham Bell
(1891) As quoted in Stacy V. Jones, You Ought to Patent That (1962), 21.

You cannot force ideas. Successful ideas are the result of slow growth. Ideas do not reach perfection in a day, no matter how much study is put upon them. It is perserverance in the pursuit of studies that is really wanted.
— Alexander Graham Bell

You have all heard of that celebrated painter who would never allow any one to mix his colors for him. He always insisted on doing that himself, and at last one of his students, whose curiosity had been aroused, said: “Professor, what do you mix your colors with?” “With brains, sir,” said the professor. Now, that is what we have to do with our observations.
— Alexander Graham Bell

Quotes by others about Alexander Graham Bell (3)

As to Bell's talking telegraph, it only creates interest in scientific circles, and, as a toy it is beautiful; but ... its commercial value will be limited.

There may be a golden ignorance. If Professor Bell had known how difficult a task he was attempting, he would never have given us the telephone.
From chapter 'Jottings from a Note-book', in Canadian Stories (1918), 178.

Dear Mr. Bell: … Sir Wm. Thomson … speaks with much enthusiasm of your achievement. What yesterday he would have declared impossible he has today seen realized, and he declares it the most wonderful thing he has seen in America. You speak of it as an embryo invention, but to him it seems already complete, and he declares that, before long, friends will whisper their secrets over the electric wire. Your undulating current he declares a great and happy conception.
Letter to Alexander Graham Bell (25 Jun 1876). Quoted in Alexander Graham Bell, The Bell Telephone: The Deposition of Alexander Graham Bell, in the Suit Brought by the United States to Annul the Bell Patents (1908), 101. Note: William Thomson is better known as Lord Kelvin.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
