"Russell at Harvard in 1914. Mr. Russell never read his lectures in that course. I sat in the front row and was exceptionally attentive. I do not recall that he even used notes. He did not refer the class to his Monist articles appearing at that time. Mr. Russell did read his lectures before the Lowell Institute, scientific method in philosophy. I was also in the front row at those lectures. The Lowell Lectures correlated quite definitely with the substance of the Harvard course. In the Harvard lectures he did not, so far as I can remember, ever refer to the Lowell Lectures."

"During the years 1911-13, when I was a student of C.I. Lewis at the University of California, he remarked to me that Russell changed his position frequently, but that this made life interesting."
