God has created all creatures in couples. In the vegetable, animal and human kingdom, all are of two sexes, and there is absolute equality between them. In the vegetable world there are male plants and female plants. Both have equal rights, there is no difference between them. Each possess an equal share of the beauty of their species. In the animal world all are male or female. Each have equal rights and there is no difference between them, they each share the advantages of their kind. In all these realms of nature the sexes have equal rights; but when we come to the world of humanity we see a difference. This difference is caused by education.
