THE GRAMMAR OF SCIENCE (1903)
OF all the travels made by man since the voyages of Dante, this new exploration along the shores of Multiplicity and Complexity promised to be the longest, though as yet it had barely touched two familiar regions - race and sex. Even within these narrow seas the navigator lost his bearings and followed the winds as they blew. By chance it happened that Raphael Pumpelly helped the winds; for, being in Washington on his way to Central Asia he fell to talking with Adams about these matters, and said that Willard Gibbs thought he got most help from a book called the "Grammar of Science," by Karl Pearson. To Adams's vision, Willard Gibbs stood on the same plane with the three or four greatest minds of his century, and the idea that a man so incomparably superior should find help anywhere filled him with wonder. He sent for the volume and read it. From the time he sailed for Europe and reached his den on the Avenue du Bois until he took his return steamer at Cherbourg on December 26, he did little but try to find out what Karl Pearson could have taught Willard Gibbs.
Here came in, more than ever, the fatal handicap of ignorance in mathematics. Not so much the actual tool was needed, as the right to judge the product of the tool. Ignorant as one was of the finer values of French or German, and often deceived by the intricacies of thought hidden in the muddiness of the medium, one could sometimes catch a tendency to intelligible meaning even in Kant or Hegel; but one had not the right to a suspicion of error where the tool of thought was algebra. Adams could see in such parts of the "Grammar" as he could understand, little more than an enlargement of Stallo's book already twenty years old. He never found out what it could have taught a master like Willard Gibbs.
