To make converts is the natural ambition of everyone.
What we do not understand we do not possess.
Progress has not followed a straight ascending line, but a spiral with rhythms of progress and retrogression, of evolution and dissolution.
Ambition and love are the wings of great actions.
A talent can be cultivated in tranquility; a character only in the rushing stream of life.
Higher aims are in themselves more valuable, even if unfulfilled, than lower ones quite attained.
