Friedrich Nietzsche said this quote

“ Of the spirit of women. - The spiritual power of a woman is best demonstrated by her sacrificing her own spirit to that of a man out of love of him and of his spirit but then, despite this sacrifice, immediately evolving _a new spirit_ within the new domain, originally alien to her nature, to which the man's disposition impels her. (from Assorted Opinions & Maxims 272)-- This is the first time among years of reading Nietzsche that i agree with his words on women: this aphorism captures a few quintessences of true and gallant womanhood, namely the will(ingness) to sacrifice (not only to others but also to the necessity that arises in a context), the balance between creative and reactive, the free-spiritedness out of such balance without conceit and swagger, and the malleability/fluidity without blind submission. (It is momentous to note that the man-woman dynamic is not binary, and that man/womanhood is not a given in one's biology - it's more something that evolves in a person over time.) ”
