“In making my calculations on the stock market, or any future event, I get the past history and find out what cycle we are in and then predict the curve for the future, which is a repetition of past market movements. The great law of vibration is based on like producing like.Like causes produce like effects. Wireless telegraphy, the phonograph and the radio are based on this law. The limit of future predictions based on exact mathematical law is only restricted by lack of knowledge of correct data on past history to work from. It is just as easy to figure 100 years or 1000 years in the future as one or two years ahead, if you have the correct starting point and know the cycle which is going to be repeated.” 《THE TUNNEL THRU THE AIR》
“我预测股票市场或任何未来事件的方法是重视其历史,并努力发现我们正处在什么样的循环中,据此指出其未来的轨迹,未来不过是市场运动的再现。伟大的波动法则就是建立在波的相似性原理上。即,相近的原因产生相近的结果。无线线、电话及收音机的发明都归功于这一法则。制约使用这种数学法则对未来进行预测的唯一因素是不能正确地理解和掌握历史的数据、资料。如果你站在正确的起点上,又知道再现历史的那种循环,那么预测100年甚至1000年将会同预测1年或者2年一样简单。”
