name frequently occurs, and on the 24th November 1813 he wrote to Knebel:  “Young Schopenhauer is a remarkable and interesting man....  I find him intellectual, but I am undecided about him as far as other things go.”  The result of this association with Goethe was his Ueber das Sehn und die Farben ("On Vision and Colour"), published at Leipzig in 1816, a copy of which he forwarded to Goethe (who had already seen the Ms.) on the 4th May of that year.  A few days later Goethe wrote to the distinguished scientist, Dr. Seebeck, asking him to read the work.  In Gwinner’s Life we find the copy of a letter written in English to Sir C.L.  Eastlake:  “In the year 1830, as I was going to publish in Latin the same treatise which in German accompanies this letter, I went to Dr. Seebeck of the Berlin Academy, who is universally admitted to be the first natural philosopher (in the English sense of the word meaning physiker) of Germany; he is the discoverer of thermo-electricity and of several physical truths.  I questioned him on his opinion on the controversy between Goethe and Newton; he was extremely cautious and made me promise that I should not print and publish anything of what he might say, and at last, being hard pressed by me, he confessed that indeed Goethe was perfectly right and Newton wrong, but that he had no business to tell the world so.  He has died since, the old coward!”

In May 1814 Schopenhauer removed from Weimar to Dresden, in consequence of the recurrence of domestic differences with his mother.  This was the final break between the pair, and he did not see her again during the remaining twenty-four years of her life, although they resumed correspondence some years before her death.  It were futile to attempt to revive the dead bones of the cause of these unfortunate differences between Johanna Schopenhauer and her son.  It was a question of opposing temperaments; both and neither were at once to blame.  There is no reason to suppose that Schopenhauer was ever a conciliatory son, or a companionable person to live with; in fact, there is plenty to show that he possessed trying and irritating qualities, and that he assumed an attitude of criticism towards his mother that could not in any circumstances be agreeable.  On the other hand, Anselm Feuerbach in his Memoirs furnishes us with a scarcely prepossessing picture of Mrs. Schopenhauer:  “Madame Schopenhauer,” he writes, “a rich widow.  Makes profession of erudition.  Authoress.  Prattles much and well, intelligently; without heart and soul.  Self-complacent, eager after approbation, and constantly smiling to herself.  God preserve us from women whose mind has shot up into mere intellect.”
