I am reminded of this quote from Ludwig von Mises book, Economic Policy:

Everything that happens in the social world in our time is the result of ideas. Good things and bad things. What is needed is to fight bad ideas...We must substitute better ideas for wrong ideas. . . . What we need is nothing else than to substitute better ideas for bad ideas. This, I hope and am confident, will be done by the rising generation. Our civilization is not doomed, as Spengler and Toynbee tell us. Our civilization will not be conquered by the spirit of Moscow. Our civilization will and must survive. And it will survive through better ideas than those which now govern most of the world today, and these better ideas will be developed by the rising generation" (p. 105).
