MY DEAR PILLON,--I have been here a week, taking the baths for my unfortunate cardiac complications, and shall probably stay six weeks longer. I passed through Paris, where I spent a week, partly with my friend the philosopher Strong, partly at the Fondation Thiers with the Boutrouxs, who had been our guests in America when he lectured a few months ago at Harvard. Every day I said: "I will get to the Pillons this afternoon"; but every day I found it impossible to attempt your four flights of stairs, and finally had to run away from the Boutrouxs' to save my life from the fatigue and pectoral pain which resulted from my seeing so many people. I have a dilatation of the aorta, which causes anginoid pain of a bad kind whenever I make any exertion, muscular, intellectual, or social, and I should not have thought at all of going through Paris were it not that I wished to consult a certain Dr. Moutier there, who is strong on arteries, but who told me that he could do nothing for my case. I hope that these baths may arrest the disagreeable tendency to _pejoration_ from which I have suffered in the past year. This is why I didn't come to see the dear Pillons; a loss for which I felt, and shall always feel, deep regret. The sight of the new "Année Philosophique" at Boutroux's showed me how valiant and solid you still are for literary work. I read a number of the book reviews, but none of the articles, which seemed uncommonly varied and interesting. Your short notice of Schinz's really _bouffon_ book showed me to my regret that even you have not yet caught the true inwardness of my notion of Truth. You speak as if I allowed no _valeur de connaissance proprement dite_, which is a quite false accusation. When an idea "works" successfully among _all the other ideas_ which relate to the object of which it is our mental substitute, associating and comparing itself with them harmoniously, the workings are wholly inside of the intellectual world, and the idea's value purely intellectual, for the time, at least. This is my doctrine and Schiller's, but it seems very hard to express it so as to get it understood! I hope that, in spite of the devouring years, dear Madame Pillon's state of health may be less deplorable than it has been so long. In particular I wish that the neuritis may have ceased. I wish! I wish! but what's the use of wishing, against the universal law that "youth's a stuff will not endure," and that we must simply make the best of it? Boutroux gave some beautiful lectures at Harvard, and is the gentlest and most lovable of characters. Believe me, dear Pillon, and dear Madame Pillon, your ever affectionate old friend, Wm. James. _To Theodore Flournoy._ BAD-NAUHEIM, _May 29, 1910_.
