To William Main 29 November [1872]
Summary
Thanks WM for his letter. CD does not think WM’s principle of [up-tending and down-tending] lines explains the cases of expression of emotions referred to, and, even if it did, the problem would remain as to why the lines should express what WM believes they do.
