“That every will must consider every other will its equal — would be a principle hostile to life, an agent of the dissolution and destruction of man, an attempt to assassinate the future of man, a sign of weariness, a secret path to nothingness.”

Woman in the Nineteenth Century (1845)
Context: We would have every arbitrary barrier thrown down. We would have every path laid open to Woman as freely as to Man. Were this done, and a slight temporary fermentation allowed to subside, we should see crystallizations more pure and of more various beauty. We believe the divine energy would pervade nature to a degree unknown in the history of former ages, and that no discordant collision, but a ravishing harmony of the spheres, would ensue.
Yet, then and only then will mankind be ripe for this, when inward and outward freedom for Woman as much as for Man shall be acknowledged as a right, not yielded as a concession.

Context: The landlord may become a direct oppressor. He may care nothing for the people, and have no object but to squeeze the most that he can out of them fairly or unfairly. The Russian government has been called despotism tempered with assassination. In Ireland landlordism was tempered by assassination.
Unfortunately the wrong man was generally assassinated. The true criminal was an absentee, and his agent was shot instead of him. A noble lord living in England, two of whose agents had lost their lives already in his service, ordered the next to post a notice in his Barony that he intended to persevere in what he was doing, and if the tenants thought they would intimidate him by shooting his agents, they would find themselves mistaken.
