“It is easy for us to criticize the prejudices of our grandfathers, from which our fathers freed themselves. It is more difficult to search for prejudices among the beliefs and values that we hold.”

Black Boy (1945)

As quoted in Thinking to Some Purpose (1939), p. 204

1920s, The Press Under a Free Government (1925)
Context: The great difficulty in combating unfair propaganda, or even in recognizing it, arises from the fact* that at the present time we confront so many new and technical problems that it is an enormous task to keep ourselves accurately informed concerning them. In this respect, you gentlemen of the press face the same perplexities that are encountered by legislators and government administrators. Whoever deals with current public questions is compelled to rely greatly upon the information and judgments of experts and specialists. Unfortunately, not all experts are to be trusted as entirely disinterested. Not all specialists are completely without guile. In our increasing dependence on specialized authority, we tend to become easier victims for the propagandists, and need to cultivate sedulously the habit of the open mind. No doubt every generation feels that its problems are the most intricate and baffling that have ever been presented for solution. But with all recognition of the disposition to exaggerate in this respect, I think we can fairly say that our times in all their social and economic aspects are more complex than any past period. We need to keep our minds free from prejudice and bias. Of education, and of real information we cannot get too much. But of propaganda, which is tainted or perverted information, we cannot have too little.
