There are two kinds of knowledge. One is general, the other is specialized. General knowledge, no matter how great in quantity or variety it may be, is of but little use in the accumulation of money. The faculties of the great universities possess, in the aggregate, practically every form of general knowledge known to civilization. Most of the professors have but little money. They specialize on teaching knowledge but the do not specialize on the organization, or the use of knowledge.
Knowledge will not attract money, unless it is organized, and intelligently directed, through practical plans of action, to the definite end of accumulation of money. Lack of understanding of this fact has been the source of confusion to millions of people who falsely believe that "knowledge is power." It is nothing of the sort! Knowledge is only potential power. It becomes power only when, and if, it is organized into definite plans of action and directed to a definite end.
