T.A. Rickard, writing in 1910:

Yet each man possesses some little bit of knowledge, whether as observation, theory, or experience, that is his very own. Thus each can contribute something to the general fund; and seeing how much he owes, it is asking but little that he give cheerfully what he can. Of course, narrow minds still continue to fondle the mean belief that to give information gratuitously is to throw away a stock in trade, and that to keep secret the professional or technical experience of a life is to possess an added weapon in the arena of industry. But this is a pitiable fallacy scarcely worthy of castigation. If adopted universally we would be today as the Hottentot or Eskimo; civilization has been evolved by the free exchange of thought and the frank transmission of experience. Whether we be advocates of free trade, fair trade, or reciprocity in matters of national industry, let us at least reject the shriveling policy of protection as applied to the worldwide traffic in ideas.
