Most valued friend,
Accept my most heartfelt thanks—even though somewhat belated—for your beautiful and significant letter. Had I wished to have you pay me a visit before receiving this letter, I now urgently repeat the sincere and spontaneous invitation extended to you when we parted in front of the "Rössli."
Do come—you need only send me a line in advance. For instance, come Saturday afternoon, remain over Sunday and return early Monday morning. Every day laborer can dispose of his time to this extent, and it should be all the more possible for a professor to do so. . . .
Now show yourself as you really are! As yet, my experiences with my German countrymen have not been altogether pleasurable. Therefore, come and rescue my faith in that which I—together with Goethe and a few others—call German liberty.
