If there is any fixed star in our constitutional constellation, it is that no official, high or petty, can prescribe what shall be orthodox in politi… - Robert H. Jackson

[T]he effect of the religious freedom Amendment to our Constitution was to take every form of propagation of religion out of the realm of things which could directly or indirectly be made public business, and thereby be supported in whole or in part at taxpayers' expense. That is a difference which the Constitution sets up between religion and almost every other subject matter of legislation, a difference which goes to the very root of religious freedom[...] This freedom was first in the Bill of Rights because it was first in the forefathers' minds; it was set forth in absolute terms, and its strength is its rigidity. It was intended not only to keep the states' hands out of religion, but to keep religion's hands off the state, and, above all, to keep bitter religious controversy out of public life by denying to every denomination any advantage from getting control of public policy or the public purse.

For over a century it has been the settled doctrine of the Supreme Court that the principle of stare decisis has only limited application in constitutional cases. It might be thought that if any law is to be stabilized by a court decision it logically should be the most fundamental of all law -- that of the Constitution. But the years brought about a doctrine that such decisions must be tentative and subject to judicial cancellation if experience fails to verify them. The result is that constitutional precedents are accepted only at their current valuation and have a mortality rate almost as high as their authors.

He loved his profession, he had a real sense of dedication to the administration of justice, he held his head high as a lawyer, he rendered and exacted courtesy, honor and straightforwardness at the Bar. He respected the judicial office deeply, demanded the highest standards of competence and disinterestedness and dignity, despised all political use of or trifling with judicial power, and had an affectionate regard for every man who filled the exacting prescription of the just judge. The law to him was like a religion, and its practice was more than a means of support; it was a mission. He was not always popular in his community, but he was respected. Unpopular minorities and individuals often found in him their only mediator and advocate. He was too independent to court the populace - he thought of himself as a leader and lawgiver, not a mouthpiece.
