Never regard study as a duty, but as the enviable opportunity to learn to know the liberating influence of beauty in the realm of the spirit for your own personal joy and to the profit of the community to which your later work belongs.
If the policy of the government, upon vital questions affecting the whole people, is to be irrevocably fixed by decisions of the Supreme Court, . . . the people will have ceased, to be their own rulers, having, to that extent, practically resigned their government into the hands of that eminent tribunal. Nor is there, in this view, any assault upon the court, or the judges. It is a duty, from which they may not shrink, to decide cases properly brought before them; and it is no fault of theirs, if others seek to turn their decisions to political purposes.
Abraham Lincoln (1809 - 1865)
