Rahel's power over the brilliant minds of her day lay in her own wonderful personality. She was unique, knew it and gloried in it. She wrote to Varnhagen, her husband and lover: "You will not soon see my like again." She understood thoroughly the limitations of her sex. "They are so surprisingly feeble," she says; "almost imbecile from lack of coherence. They lie, too, since they are often obliged to, and since the truth demands intelligence." ... "I know women: what is noble in their composition keeps together stupidity or madness." ... And she speaks of their "clumsy, terrible stupidity in lying." But, despite Rahel's opinion of women, or because of her understanding of their needs, she was a true feminist and looked toward their liberation through development and self-expression. Ellen Key writes: "How Rahel, with her lucidity of thought, would have exposed the modern superstition that it is in _outward_ departments of work that woman gives expression to her human 'individuality.' She says by true economy 'nature keeps woman nearer to the plant'! This 'economy' is easily understood; it is because the tender life is woman's creation and because that life requires tranquillity for its genesis and growth; because a woman taken up by the problems of external life ... no longer possesses the psychological qualifications which are indispensable in order that a child's soul may grow in peace and joy; because, in other words, _children_ need _mothers_, not only for their physical birth but for their human bringing-up. Rahel hits the very center of the spiritual task of motherhood when she says that if she had a child she would help it to learn to listen to its own inmost ego; everything else she would sacrifice to this.... The progress or ruin of humanity depends, in Rahel's prophetic view, upon the capacity of the mothers for performing their task." How Rahel had listened to her own inmost ego is shown by the following characterization by Ellen Key. "Rahel probably did not know a single date in the history of Greece, but she read Homer in Voss's translation; it made her declare that 'the Odyssey seems to me so beautiful that it is positively painful,' and she discovered that Homer is always great when he speaks of water, as Goethe is when he speaks of the stars. Probably she could not enumerate the rivers of Spain, but she knew _Don Quixote_. In a word, she was the very opposite of the kind of talent that passes brilliant examinations and is capable of carrying 'completely undigested sentences in its head.' What Rahel could not transform into blood of her blood did not concern her at all. There was such an indestructible 'connection between her abilities,' such an intimate 'co-operation between her temperament and her intelligence,' that there was no room in her for all the unoriginal ballast of which the views and opinions of most other people are made up: she could only keep and only give what was her own."
