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.
Felix FrankfurterUltimately there can be no freedom for self unless it is vouchsafed for others; there can be no security where there is fear, and a democratic society presupposes confidence and candor in the relations of men with one another and eager collaboration for the larger ends of life instead of the pursuit of petty, selfish or vainglorious aims.
