I was overjoyed recently when I read that there are still people who, going beyond the ordinary routine of life, have already perceived the practical life as something important. Recently a news item spread through the world, describing how Edison tested the people he wished to prepare for some sort of practical work. It did not interest him at all whether or not a merchant was able to keep books. That, he said, can be learned in three weeks if one is a reasonable, intelligent person. None of these specialties interested him at all; these one can learn.
When Edison wished to know whether people would be of any use in practical life, however, he tested them by asking them questions like, “How large is Siberia?” Thus when he wished to discover whether someone was a good bookkeeper, Edison did not ask whether he could conduct an audit properly, but he asked, “How large is Siberia?” or “If a room is five meters long, three meters wide, and four meters high, how many cubic meters of air are contained in this room?” and similar questions. He posed questions like, “What is standing at the place where Caesar crossed the Rubicon?” and so on, just general questions. And according to the extent to which a person could answer such questions, Edison hired him as a bookkeeper, or whatever. He knew that if a person could answer such a general question this was a proof that his schooling had not been in vain, that as a child he had developed mobile thoughts, and this is what Edison demanded.
This is how practical life really should be conducted, whereas in recent times we have steered precisely in the opposite direction, succumbing more and more to specialization, so that finally one could really despair of finding the people needed for practical life. It is impossible to get anyone to do something outside the pigeonhole into which he wants to fit. Already today it must be said that in this way too we must work toward the mobility of thoughts. If there is such a working toward the mobility of thoughts, then these thoughts will not harden, and Ahriman will be in a difficult position.
