The problem is not only one of actual censorship. The shadow of fear cast by these pressures leads, we suspect, to an even larger voluntary curtailment of expression by those who seek to avoid controversy. Such pressure toward conformity is perhaps natural to a time of accelerated change. And yet suppression is never more dangerous than in such a time of social tension. Freedom has given the United States the elasticity to endure strain.
Freedom keeps open the path of novel and creative solutions, and enables change to come by choice.
Every silencing of a heresy, every enforcement of an orthodoxy, diminishes the toughness and resilience of our society and leaves it the less able to deal with controversy and difference. Now as always in our history, reading is among our greatest freedoms. The freedom to read and write is almost the only means for making generally available ideas or manners of expression that can initially command only a small audience. The written word is the natural medium for the new idea and the untried voice from which come the original contributions to social growth. It is essential to the extended discussion that serious thought requires, and to the accumulation of knowledge and ideas into organized collections.
