It is curious to note the old sea-margins of human thought! Each subsiding century reveals some new mystery; we build where monsters used to hide themselves.
Experience shows that what great role pratice and experience play in education; pratice, the prolonged exercice lead to habit: exemple suggests imitation. Habit can become a second nature, but, wrongly directed (or guided), it may also heighten (or intensify) unfortunate tendencies and be an obstacle to progress.
The more we progress the more we tend to progress. We advance not in arithmetical but in geometrical progression. We draw compound interest on the whole capital of knowledge and virtue which has been accumulated since the dawning of time.
