On leaving the Kingsboroughs, Mary found work of a kind more congenial to her disposition, as Mr. Johnson, the bookseller in St. Paul's Churchyard who had taken her pamphlet, now gave her regular work as his "reader," and also in translating. Now began the happiest part of Mary's life. In the midst of books she soon formed a circle of admiring friends. She lived in the simplest way, in a room almost bare of furniture, in Blackfriars. Here she was able to see after her sisters and to have with her her young brother, who had been much neglected; and in the intervals of her necessary work she began writing on the subjects which lay nearest to her heart; for here, among other work, she commenced her celebrated Vindication of the Rights of Woman, a work for which women ought always to be grateful to her, for with this began in England the movement which, progressing amidst much obloquy and denunciation, has led to so many of the reforms in social life which have come, and may be expected to lead to many which we still hope for. When we think of the nonsense which has been talked both in and out of Parliament, even within the last decade, about the advanced women who have worked to improve the position of their less fortunate sisters, we can well understand in what light Mary Wollstonecraft was regarded by many whom fortunately she was not bound to consider. Her reading, which had been deep and constant, together with her knowledge of life from different points of view, enabled her to form just opinions on many of the great reforms needed, and these she unhesitatingly set down. How much has since been done which she advocated for the education of women, and how much they have already benefited both by her example and precept, is perhaps not yet generally enough known. Her religious tone is always striking; it was one of the moving factors of her life, as with all seriously thinking beings, though its form became much modified with the advance in her intellectual development.

Her scheme in the Vindication of the Rights of Woman may be summed up thus:—

She wished women to have education equal to that of men, and this has now to a great extent been accorded.

That trades, professions, and other pursuits should be open to women.
This wish is now in progress of fulfilment.

That married women should own their own property as in other European countries. Recent laws have granted this right.

That they should have more facilities for divorce from husbands guilty of immoral conduct. This has been partially granted, though much still remains to be effected.

That, in the case of separation, the custody of children should belong equally to both parents.

That a man should be legally responsible for his illegitimate children. That he should be bound to maintain the woman he has wronged.

Mary Wollstonecraft also thought that women should have representatives in Parliament to uphold their interests; but her chief desires are in the matter of education. Unlike Rousseau, she would have all children educated together till nine years of age; like Rousseau, she would have them meet for play in a common play-ground. At nine years their capacities might be sufficiently developed to judge which branch of education would be then desirable for each; girls and boys being still educated together, and capacity being the only line of demarcation.

Thus it will be seen that Mary's primary wish was to make women responsible and sensible companions for men; to raise them from the beings they were made by the frivolous fashionable education of the time; to make them fit mothers to educate or superintend the education of their children, for education does not end or begin with what may he taught in schools. To make a woman a reasoning being, by means of Euclid if necessary, need not preclude her from being a charming woman also, as proved by the descriptions we have of Mary Wollstonecraft herself. Doubtless some of the most crying evils of civilisation can only be cured by raising the intellectual and moral status of woman, and thus raising that of man also, so that he, regarding her as a companion whose mind reflects the beauties of nature, and who can appreciate the great reflex of nature as transmitted through the human mind in the glorious art of the world, may really be raised to the ideal state where the sacrilege of love will be unknown. We know that this great desire must have passed through Mary Wollstonecraft's mind and prompted her to her eloquent appeal for the "vindication of the rights of woman."
