Alexander Graham Bell
I have always considered myself as an Agnostic.
Alexander Graham Bell
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 that he can help thinking or breathing.
Alexander Graham Bell
A man, as a general rule, owes very little to what he is born with - a man is what he makes of himself.
Alexander Graham Bell
Great discoveries and improvements invariably involve the cooperation of many minds.
Alexander Graham Bell

Alexander Graham Bell
