On verso of Millard's letter. "I think no general rule can be given as to how far one should avow unconventional opinions if the avowal is going to give pain. When I was young, I concealed my rejection of religion from my family, but I could not continue to do so after I was grown up. I think one must ask oneself whether there is any public reason for avowing one's opinion on this or that. Whether this is the case depends upon the nature of one's work."
