What about the ovarian idea?

The animus is the deposit, as it were, of all woman's ancestral experiences of man — and not only that, he is also a creative and procreative being, not in the sense of masculine creativity, but in the sense that he brings forth something we might call the the spermatic word. Just as a man brings forth his work as a complete creation out of his inner feminine nature, so the inner masculine side of a woman brings forth creative seeds which have the power to fertilize the feminine side of the man.

Maybe they just needed to get their hair out of their eyes

It seems that women have made few contributions to the discoveries and inventions in the history of civilization; there is, however, one technique which they may have invented—that of plaiting and weaving. If that is so, we should be tempted to guess the unconscious motive for the achievement.

Naturally exuding creativity

Just as we are born with hundreds of thousands more eggs than we will ever use, we also have far more creative ideas than we will ever be able to bring into being. Some of these eggs and ideas are destined to take root and grow if we're willing to fertilize and support them. Others end in miscarriage or stillbirth. This is not a sign of failure. Nor is it a design flaw. Instead, this process simply reflects the adaptability of Nature, a force that keeps creating and experimenting with form and function in a variety of changing environments. When one thing doesn't work, she tries another, and just keeps sending out more eggs, sperms, seed pods—and ideas!

The fury of words

I was lying on the grass ... reading William Faulkner's The Sound and the Fury. ... Suddenly in the middle of a passage, the power of the words rose up and whacked me on the forehead. I felt the earth move as if a huge safe were being swiveled open and afterwards felt flushed and stunned as you are after sex. I'd had this reaction before—to other books, and to music and painting, but this time as I stared at the light—green blades of grass in front of me, vibrating, I was aware that it was the writer who had done something to me. And I thought, I'd like to do that to someone back.

The woman artist as inner-critic

Why have we not had more female writers, painters, scientists, sculptors, or artists. One explanation offered is that many women do not perceive themselves as creators, follow their interests into career preparation, or place importance on the works they produce. Moreover, the problem may be further exacerbated even when a women produces an original, creative work of art, as some researchers have found that women are more conscious of criticism and find it more difficult to deal with negative perceptions of their work.
