There are, indeed, two forms of discontent: one laborious, the other indolent and complaining. We respect the man of laborious desire, but let us not suppose that his restlessness is peace, or his ambition meekness. It is because of the special connection of meekness with contentment that it is promised that the meek shall 'inherit the earth.' Neither covetous men, nor the grave, can inherit anything; they can but consume. Only contentment can possess.
John RuskinWe must note carefully what distinction there is between a healthy and a diseased love of change; for as it was in healthy love of change that the Gothic architecture rose, it was partly in consequence of diseased love of change that it was destroyed.
