The great expansion of the market by modern inventions in transportation has broken up all the former local and petty monopolies, and is rapidly making of the industry and commerce of mankind a whole which cannot be divided by geographical lines. The conditions of competition in such a system are no doubt onerous to the last degree. The conditions that must be taken into account to win success are numerous and complicated. The nerve-strain of comprehending and of justly estimating the factors, and of following their constant variations, is too great for any one to endure. Foresight must be used, yet there are so many unknown quantities that foresight is impossible; if the attempt is made to master all the unknown quantities, then the task is so enormous that it cannot be accomplished. Furthermore, the relations with other persons in the industrial system are necessarily close. It is impossible to escape such relations, and it is impossible to avoid a share in the consequences of the mistakes and incompetence of the others. It must be added that, at a time when the advance in the arts has forced the whole industry of the globe into intimate relations which nothing can possibly cut off, legislative interferences have produced artificial and erratic currents in the industrial and commercial relations of all countries. The consequences are disappointing and disastrous incidents in the history of industry. At the same time the improvements in the communication of intelligence have made it possible for men farthest apart in space, language, and nationality, if they have confidence in each other’s business ability and command of capital, to coöperate by personal agreements.
