A stammering man is never a worthless one. Physiology can tell you why. It is an excess of sensibility to the presence of his fellow creature, that makes him stammer. – Thomas Carlyle, letter to Ralph Waldo Emerson, 1843 November 17th
Great discoveries and improvements invariably involve the co-operation 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
