My dear Mr. De Casseres:
I wish to thank you for remembering me with occasional copies of your printed writings. I trust that you will send me more.
I have a sincere admiration for your remarkable powers of expression; and many of your ideas meet with my entire approval.
But of course I do not accept the philosophy of ultimate pessimism. I cannot follow you into the Cimmerian darkness where you sometimes wander. Man has built his own hells, and he will sometime climb out of them to stand upon a cliff of stars.
Cordially yours,
Edwin Markham
