To William Main 29 November 1
Down, | Beckenham, Kent.
I am much obliged for your very courteous letter. If you ever have time & inclination to read my book,2 I think that you will see that all the cases, referred to, will not be easily explained through your principle of the lines. And even if they could be so explained, there would remain the solution why perpendicular & inclined lines should express what you believe they do.—
Dear Sir | Yours faithfully & obliged | Ch. Darwin
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.
