Certainly the affirmative pursuit of one's convictions about the ultimate mystery of the universe and man's relation to it is placed beyond the reach of law. Government may not interfere with organized or individual expressions of belief or disbelief. Propagation of belief - or even of disbelief - in the supernatural is protected, whether in church or chapel, mosque or synagogue, tabernacle or meeting-house.

We forget that the most successful statesmen have been professionals. Lincoln was a professional politician.

The ultimate touchstone of constitutionality is the Constitution itself, and not what we have said about it.

All our work, our whole life is a matter of semantics, because words are the tools with which we work, the material out of which laws are made, out of which the Constitution was written. Everything depends on our understanding of them.

Fragile as reason is and limited as law is as the institutionalised medium of reason, that's all we have between us and the tyranny of mere will and the cruelty of unbridled, undisciplined feelings.

The words of the Constitution... are so unrestricted by their intrinsic meaning or by their history or by tradition or by prior decisions that they leave the individual Justice free, if indeed they do not compel him, to gather meaning not from reading the Constitution but from reading life.

It is easy to make light of insistence on scrupulous regard for the safeguards of civil liberties when invoked on behalf of the unworthy. It is too easy. History bears testimony that by such disregard are the rights of liberty extinguished, heedlessly at first, then stealthily, and brazenly in the end.
