The question which titles this article is answered by Mary Baker Eddy, the Discoverer and Founder of Christian Science, in "Unity of Good" (p. 51): "Woman is the highest species of man, and this word is the generic term for all women; but not one of all these individualities is an Eve or an Adam."
The first chapter of Genesis attests the real facts of creation, a creation declared to be spiritual, wholly good, and complete. The record reads, "So God created man in his own image, in the image of God created he him; male and female created he them." This pronouncement of the spiritual unity of man and woman is the scientific truth about the real man. It is opposed to the material untruth allegorically narrated in the second chapter of Genesis.
The latter account asserts that during a mesmeric sleep a rib was extracted from a man of dust to make woman. The entire import of the second chapter, from the sixth verse on, implies that woman is separate from man. It is a contradiction of the truth affirmed in the preceding chapter.
