“Intellect is not sexed;… strength of mind is not sexed; and … our views about the duties of men and the duties of women, the sphere of man and the sphere of woman, are mere arbitrary opinions, differing in different ages and countries, and dependent solely on the will and judgment of erring mortals.”
Letter 9 (August 25, 1837).

Kosmos (1845 - 1847)
Context: From the remotest nebulæ and from the revolving double stars, we have descended to the minutest organisms of animal creation, whether manifested in the depths of ocean or on the surface of our globe, and to the delicate vegetable germs which clothe the naked declivity of the ice-crowned mountain summit; and here we have been able to arrange these phenomena according to partially known laws; but other laws of a more mysterious nature rule the higher spheres of the organic world, in which is comprised the human species in all its varied conformation, its creative intellectual power, and the languages to which it has given existence. A physical delineation of nature terminates at the point where the sphere of intellect begins, and a new world of mind is opened to our view. It marks the limit, but does not pass it.
